Description
TECHNICAL FIELD
[0001] This invention relates to a manufacture method of wet-tissue
with antimicrobial and anti-fungus function with Non-woven fabrics,
Cotton fabrics and other tissue papers or nano particle treated
on-woven fabrics which already have antimicrobial and anti-fungus
function, more particulary to the technology how to make those
materials to have antimicrobial and anti-fungus functions by adding
nano particles.
BACKGROUND ART
[0002] In general, the disposable wet tissues are used at various
commercial and public places such as restaurants, public
transportation and hospitals by unspecified persons to clean
themselves and take care of excrements of kids.
[0003] As they clean up by scrubbing the skin with the wet tissue,
it is required to have stability with skin and strong function to
remove foreign materials from the skin of users.
[0004] Therefore, the wet tissues are being manufactured with paper
or fabrics of soft materials such as non-woven fabrics, and it is
cut to specific sizes and add distilled water before they are
sealed and packed in synthetic resin packing material.
[0005] The non-woven fabrics as the major raw materials for wet
tissue are manufactures by put the fabrics parallel or unfixed
direction and combine to make it felt shape. There are Viscose
rayon, Polyester (PE), and Polypropylene (PP) as synthetic fibers,
and cotton as well as natural pulp as raw materials for wet
tissues.
[0006] There are basically two ways to manufacture the non-woven
fabrics; they are immersion method and dry method. The immersion
method is same as sheet forming method to making paper product that
spread synthetic resin binder on the fabrics and drying and
heating. The dry method is erupt synthetic resin on the fabrics
like a cotton sheet and heat and drying.
[0007] There are Non-woven fabrics of Chemical bonding type,
Thermal bonding type, dry/ wet type including Air Ray non-woven
fabrics, Needle punching type, Melt Blown type and Stitch type
depending on manufacturing process.
[0008] The chemical Bonding type of Non-woven fabric is being
manufactured through drying process by having adhesives penetrate
into fabrics while web bonding.
[0009] And there are two ways to manufacture non-woven fabrics
depending on how to make the adhesives penetrate into fabrics: one
is sediment adhesion method which is to penetrate by dipping, and
the other one is Spray method which is to spray the adhesives on to
fabrics. The non-woven fabrics using sediment adhesion method are
OB type, CB type and MB type.
[0010] The proper fibers to do Chemical bonding are Viscose Rayon,
Polyester and blended fibers of Viscose Rayon and polyester.
According to the manufacturing method of chemical bonding, the
shapes and features of the non-woven fabrics can be differ per the
adhesives used for web formulation. The adhesives include soluble
types and non-soluble, soft types and hard types.
[0011] Non-woven fabrics with the chemical Bonding method can be
manufactured in many different ways per its production process,
fabrics and adhesives, and it has variety and wide applications
such as for automobile, Electronics, internal use for Electronics
products, Filters, Adhesive tapes, Civil engineering and cleaner as
industrial application and artificial flowers, general pacing
materials, medical adhesive tape and cosmetics mask pack as general
applications.
[0012] Non-woven fabrics of the thermal bonding method is being
manufactured by mixing raw materials of Polypropylene(P.P.) which
is flammable at low temperature, and melt it by heat or pressure
and combine fibrous tissue and form the Web. This method is being
used to produce lower weight non-woven fabrics.
[0013] There are Polypropylene (PP), Blended Yarn (Polyester+PE,
PP+PE, Polyester+PP), Viscose Rayon and Polyester as fabric raw
materials for Thermal Boding type of Non-woven Fabrics. As the
Viscose Rayon itself is impossible to form the Web, Mix with
Polypropylene or Blended fibers.
[0014] Such Thermal Bonding type Non-woven fabrics are lower in
tensile strength but has soft touch-feeling, superior
absorptiveness, adhesive is not required, form the Web by heat
which does not generate harmful materials. When the blended fiber
is used, it has superior adhesive property by heat, and therefore,
it is being widely used for baby diapers, sanitary diapers,
sanitary masks, Wet tissues and Wipers.
[0015] Span bond type non-woven fabric is being manufactured by for
the Web with pressure after melting and spraying the fabric chips.
Mainly Polyester and Polypropylene are being used as material chips
and sometimes Nylon is also used.
[0016] Span bond has the advantage of tensile strength is higher
and superior in durability and chemical resistance while it has
lower tensile strength because it is filament that does not stop
from the starting point to the end in production without cut. It is
being used for industrial applications such as interior material
for automobiles, Filter, Cable protector, Civil Engineering,
Agricultural and Coating, and packing material for flowers, basic
wall papers, packing materials, Beds and furniture and printing
materials as general industrial applications.
[0017] As Air-ray type of Non-woven fabric is being manufactured
with Compressed air and adhesives, there is no difference in
tensile strength of parallel and horizontal direction.
[0018] It is being used as Filter, wick, carpet, forming agent,
Wipers (rug, dishcloth, towel) and insulation materials.
[0019] Wet Non-woven fabrics use the same manufacturing process as
paper manufacturing which is sheet forming method. The difference
is that it does not use pulps as materials but uses other fabrics
which allow free control of its specification, and being used for
Wipers, Towel, Filter bag and cover of Diapers.
[0020] Needle-punching type non-woven fabrics are manufactured with
special needles to form the web which enables to vary its thickness
of the products with number of punching and density of needles. It
is applied to Carpet, Blanket, Filter, wick coating agent.
[0021] Span-ray non-woven fabrics are manufactured by spraying high
pressure water to the fabrics to form the web. Viscose Rayon,
Polyester, Polypropylene as itself or blended are used as raw
materials. As the products is good in flexibility, breath-ability
and hygienic, it is used for Medical wick, household items, Coating
agent, roofing materials, wiper and sanitary products.
[0022] Specially, as the Span-ray non-woven fabrics have soft-touch
feeling, superior absorptiveness of water, superior cleaning
function and form web with water, its manufacturing process is
hygienic, and therefore it is used mainly for sanitary products
such as Wet Tissue, Wiper and cosmetic mask pack.
[0023] Melt blown type non-woven fabrics are manufactured by
weaving blended high molecule to get ultra thin yarn with high
compressed heat and form the web. With its superiority of
flexibility, permeability and insulation, it is used for Filter,
Insulation materials, Wipers, Oil absorbing sheet and sanitary
napkins.
[0024] And as the Starch bond type non-woven fabrics do not use
adhesives but quilting method, it is thin but high tensile strength
and it is used mainly for wick and interior materials for
automobile.
[0025] The other hands, the general wet tissues are manufactured to
clean the body partially by adding specially prepared water to
cottons or pulps or some of above-mentioned non-woven fabrics (i.e.
thermal bonding type non-woven fabrics and etc.).
[0026] Moisturizer and surfactant are generally added to specially
prepared water for wet tissue to produce wet tissues. And those wet
tissues use chemical preservatives, alcohol and perfumeries to
protect contamination of the wet tissues, possible changes of the
characters of the materials added and to lessen the bad smells.
[0027] The chemical preservatives are Benzoic acid, Sorbic acid,
Methylparaben, Ethylparaben, Propylparaben, Butylparaben,
3-iodo-2-propynyl butyl carbonate, 4-thiazolyl-benzimidazole,
2-(4-thiazolyl)-benzimidazole, benzalkonium chloride, polyvinyl
Butyral, deiodinemethyl, p-tolyulfanilamide,
2.4.5.6-tetrachliro-iso-butyno-nitryl, p-hydroxybenzoate.
[0028] All of those materials are skin irritator and may generate
skin problems, and it has high possibility to be accumulated to the
body of kids who are weak in resistance and it can be the reason
for atopic skin problems.
[0029] Again, those types of additives which are chemical
preservatives contained in wet tissue can generate irritation to
the skin or harmful to human body.
[0030] Further, antimicrobial materials and alcohol generate bad
smell that gives bad feeling.
[0031] Even though the antimicrobial materials and alcohol are
added to wet tissues, there is still high possibility for the
bacteria and fungus to be increased in the closed containers
because the moisturizer, plasticizer, antioxidant, adhesive agents
which are the additive materials for non-woven fabrics (PET, PP,
PE, Nylon, Viscose rayon, Pulp, Cotton) become nutritive elements
to microorganism in the container where the proper temperature is
maintained and Ultraviolet rays is blocked.
[0032] Further, there is high possibility for the bacteria to be
increased and fungus is generated during the manufacturing and
distribution process if the non-woven fabrics as raw material for
wet tissues are contaminated, and therefore, the chemical
preservatives are used. However, as a specific chemical
preservatives is not able to cover all different bacteria, it is
fact that at least 2-3 different kind of chemical preservatives of
large quantity need to be used, total 3,000-6,000 ppm in
general.
[0033] Accordingly, considering that the chemical preservatives has
strong possibility to raise skin problem if it is added to the
specially prepared water for wet tissue to kill fungus, using nano
silver as a replacement to chemical preservatives to kill fungus
are being seriously considered.
[0034] For an example, Korean Laid-Open Patent No. 10-2006-1758
shows that Silver colloid as antimicrobial material solved color
change problem to yellowish and black and it has antimicrobial
effect. It also described on the technology to apply it for Wet
Tissues with Silver Colloid of smell-less and harmless to human
body.
[0035] According to the technology of the above-mentioned Korean
Laid-Open Patent No. 10-2006-1758, after forming 100 ppm of nano
silver Colloid in the first process, mix about 1 ppm of sodium
hypochlorite into this colloid as catalyst in the second process,
150 ppm of nano silver colloid in the first process, mix calcium
carbonate as catalyst into the out-put of the second process to get
silver colloid of pH8.5 by melting the calcium carbonate in the
third process, mix sodium acetate into the out-put of the third
process to control to get pH7.5 in the fourth process, produce
antimicrobial silver colloid of unchangeable color by filtering
silver compound and then, produce wet tissue of unchangeable color
to yellow by dip the wet tissue materials into the silver colloid
in the last process.
[0036] The above-mentioned process shows that it solved the
problems of color changes caused by halogen compound and mineral
ingredients or lye and other toxic materials to use it as
antimicrobial materials to white wet tissues. In the first process,
put chlorine (halogen material) into silver colloid and have it
react, and compounding calcium carbonate to yellowish color to make
the pH weak alkali.
[0037] Further, it describes that transparent silver colloid can be
made through filtering the floating particles of transparent white
color which are formed by neutralization with nitric acid soda.
[0038] However, regardless of its reality, it concentrates on
protecting against color changes to yellowish to produce wet
tissue. It does not contain enough technical information on the
optimistic size of solid silver to control and get rid of
fungus.
[0039] The technical explanation to produce wet tissue with
specific silver colloid produced through the 1st -5th process is
rather limited, and there is n definition if such silver colloid is
ion or metal which gives us doubts antimicrobial efficacy, effects
against fungus and its durability. If that is ion, it can be easily
combined to other materials which may be remained in the raw fabric
and treated water of wet tissue, and it is hard to expect its
durability.
[0040] The above-mentioned manufacturing method of wet tissue is
the technology which make difficult to estimate the durability
after open the pack and overall validity of the products but simply
considers how to provide antimicrobial function to treated water
for wet tissues.
[0041] As an another example, Korean Laid-Open Patent No.
10-2006-95685 provides the method of protecting the propagation of
microbes by wetting the wet-tissues into nano silver contained
water in the manufacturing process of wet tissue and the method how
to eliminate the microbes effectively by transferring the harmless
nano silver materials to the hands of customers.
[0042] According to the method, it is required to mix nano silver
treated water of 25-150 ppm to wet-tissue which is formed with
compound of nano silver treated water, surfactants, anti-fungus
materials and preservatives to papers and fabrics.
[0043] However, the above-mentioned Korean Laid-Open Patent No.
10-2006-95685 describes that anti-fungus materials need to be added
besides nano silver treated water used for antimicrobial function.
But it has no definition on the size of nano silver particles of
the nano silver treated water used but only concentration level
only. This can be the case only when the nano silver is added as
supplements for antimicrobial function while anti-fungus materials
and preservatives are also used.
[0044] As notices, the nano-sized silver particles shows its
antimicrobial and anti-fungus functions by energy of the surfaces
with increased surface area, the technology is rather unclear and
has practical problem to apply with only limited concentration
level unless it explains clearly about the particle sizes. It
emphasizes only on adding antimicrobial function instead of
anti-fungus function limited to manufacturing water in the wet
tissue manufacturing process.
[0045] As an another example, Korean Laid-Open Patent No.
10-2006-110952 suggests functional wet tissue that eliminates
accumulated heavy metals from the skin, activate cells and have the
functions of smoothing blood circulation, hygienic, superior safety
to the skin and antimicrobial and antifungal functions against
microbes stays on the skin by adding polyglucosamine, ceramic
liquid, lotion, aloe and vitamin to nano silver material treated
Span lace which is natural pulp.
[0046] According to the above-mentioned Korean Laid-Open Patent No.
10-2006-110952, it is to mix 30-35 weight(wt) % of Span lace,
nature pulp material to mixed water of 63-69 wt % with nano silver
powder of 1-2 wt %. This nano silver power must be either 10-100
ppm in concentration with 1-10nm in size or nano silver coating
powder (capsule type) of 10-100 ppm in concentration with 100-200
nm in size. And mix 0.2-0.4 wt % of polyglucosamine and 0.6-0.8 wt
% of liquid ceramic into above liquid and add 1-2 wt % of at least
two kinds of mixture of lotion, aloe and vitamin or one of
them.
[0047] However, the technology is limited to apply nano silver
powder or nano silver coated capsule and it has some difficulties
to execute and apply it to keep anti-fungus function with 1-100 ppm
concentration of nano silver itself alone a the concentration level
is not sufficient.
[0048] In fact, the most serious problem of contamination during
the manufacturing process and usual contamination of the fabrics
for wet tissue is Aspergillus Niger. It has been already proved
through a few experiments that it is not possible to protect or
eliminate the Aspergillus Niger by silver alone under the
circumstances in the wet tissue pack with nano particle of 1-10 nm
with 100 ppm concentration.
[0049] An early experiment has been carried out and proved that
150-200 ppm concentration is required to use nano silver alone for
tissue manufacturing water.
[0050] Further, it still has possibility to have color change into
yellow by reacting with UV or form precipitates by reacting with
remaining sulfides in the fabrics.
[0051] And, it has been confirmed a few times through experiments
that 2-4 times of concentration level of 200 ppm are required to
keep anti-fungus function as the energy value is decreased per
surface size with nano silver of 10-100 nm size.
[0052] As the technology to use it after coating the nano silver
particles to the surface of the particles or put the particles into
the capsule, it has high possibility to offset its surface energy
which reacts on the surface of nano silver particles.
[0053] This is the basic difference technology in antimicrobial and
anti-fungus efficiency from the technology which utilizes the
technology of surface energy itself of uncoated nano particles of
metals of not only silver but also platinum, gold, copper, zinc and
selenium.
[0054] And, even though we assume that all the contents of
technology in the above-mentioned Korean Laid-Open Patent No.
10-2006-110952 are proper, it uses powder or capsule type of silver
only, it has high possibility of color changes and color
contamination. It is limited to only to use for manufacturing water
for wet tissues, not considering antimicrobial and anti-fungus
treatment to non-woven fabrics and pulps.
[0055] According to Korean Patent No.10-0693293 suggested by the
inventor, it is featured to use below 10 nm particle size to
produce preservatives-free cleaning wet tissue which has
antimicrobial and deodorizer functions using nano particles of
metals or to use 1-2 nm nano silver particles to minimize the
quantity to be used. The quantity to use is 50-100 ppm
concentration when the particle size of below 10 nm is used, and
0.4-1 ppm concentration is used with 1-2 nm particle size.
[0056] In the above-mentioned patent, Nano silver is used for
manufacturing water of tissues only. However, the reject rate
(fungus incidence) came to 1-5% in practical repeated mass
production.
[0057] 10,000 packs each were produced 3 times in year of 2006, the
Aspergillus Niger were found and confirmed from average min. 100
packs to max 500 packs out of each lot in 7-30 days during storage
and distribution period. It is confirmed that the Aspergillus Niger
were grown 50% by contamination of non-woven fabrics, 30% by
contaminated manufacturing process, and 20% by other factors.
[0058] This indicates that there are different levels of sanitary
environmental conditions contamination levels between the
manufacturers and there are limitations to maintain sanitary
manufacturing process which is required to manufacture wet tissues
with non-woven fabrics.
[0059] It is difficult to produce good antimicrobial and antifungal
wet Tissue with the above-mentioned patente technology by mixing
nano silver into tissue manufacturing water to provide
antimicrobial and anti-fungus functions to the wet issue because
the non-woven fabrics itself as raw materials can be contaminated
during its manufacturing, distribution and handling process or
possibility of spores in the air stick to the non-woven fabrics
which can be the factor for bacteria or fungus to increase.
[0060] Considering this contamination problem of non-woven fabrics,
the technology to provide antimicrobial and deodorizer functions to
the non-woven fabric itself has been suggested.
[0061] As examples, Korean patent No. 10-643515 introduces
polypropylene span-bond type non-woven fabrics and its
manufacturing technology which solves the problems of human beings
and environment caused by using improper antimicrobial and
deodorizer chemicals, increases economical efficiency for the
necessity of drying process against moisture absorption and work
efficiency against increased pressure raised by uneven dispersion
in the polymer and problems of cut-thread and provide antimicrobial
and deodorizer functions not to allow the virus, bacteria and
fungus to inhabit.
[0062] According to the Patent, it is produced with pure metallic
nano silver particles of 1-3 nm level combined with silica
particles of below 1 nm and polypropylene and the added quantity of
nano silver is to be 10-1,000 ppm of total polypropylene resin of
Polypropylene span bond non-woven fabric, Melt blown span bond
multilayer non-woven fabric, using the prefabricated master batch
chip contains 0.01.about.10 wt % of nano silver and the added
quantity of nano silver is to be 10-1,000 ppm of total
polypropylene resin of polypropylene span bond non-woven fabric or
polypropylene span bond, Melt blown span bond, multilayer non-woven
fabric, polypropylene chip have 20.about.80 g/10 min Melt Flow
Rate(MFR) as a main raw material through the melt, mix, homogenize
on the extruder, melt spinning through the spinneret, formed
filament after cooling, drawing, formed web on the porous conveyer
belt, move to the calendar for heating bond process and then they
have stability of formation.
[0063] According to the above-mentioned Patent No. 10-643515,
silica of below 10 nm is combined to silver of 1-3 nm level;
however, there is no description on the detail method of it. Though
we assume this is the case silica is used as inclusion body as
usual, the silica particles do not require the inclusion body
except a special case. The abovementioned technology may reach the
result of decreasing the increased energy with increased surface of
nano particles because the surface area is decreased if silver
particles of the pure metal are contained in the inside of silica,
inclusion body.
[0064] The way to combine silver and silica without using silica as
inclusion body becomes the decisive factor of cut in spinning
process regardless of it is used as binder to be coupled.
[0065] And, crushing the inorganic silica with physical method, it
can be just 10 nm level under the current technology level due to
the manufacturing technology of related crusher, tolerance in
process and related materials.
[0066] Accordingly, the technical explanation is different from the
one that uses silver of 1-3 nm to non-woven fabrics directly as
described because it must be considered that the nano particle size
exceeds 50 nm if the size of combined silica with silver is 50 nm
even though the silver size is 1-3 nm.
[0067] And, if the patent describes that they use silver Ion
instead of silver metal, it is common to use silica or zeolite as
inclusion body for the stability, which is different from the nano
technological materials and the silica must be foreign materials to
polypropylene as it is used together with silica for stability even
though it uses silver metal. Accordingly, if we compare it to the
case of mixing nano silver particles into thermostatic plastic
resin, the productivity (increase of pressure in the cylinder, wear
out of screws and nozzles) and reliability (tensile strength,
shrinking rate, stain ability and etc.) may not be enough.
[0068] And, the above-mentioned Korean patent No. 10-643515
describes the manufacturing method of non-woven fabrics with nano
silver particles by mixing to polypropylene materials only.
[0069] It does not describe on the manufacturing method of
non-woven fabrics that use Viscose Rayon and polyester or others as
raw materials for the fabrics.
DISCLOSURE

anti-fungus functions by adding nano particles of either one of
platinum, gold, silver, germanium, selenium, zinc, copper and
tungsten or more than 2 of selected metals, and, mix this fabrics
material into distilled water of purified water so that the wet
issue can have optimistic level of antimicrobial and anti-fungus
function.
[0072] The third objective of this invention is to provide a

mixing nano particles of one or one metals of gold, platinum,
silver, germanium, selenium, zinc, copper and tungsten into fabric
materials such as viscose rayon, polyester, polyethylene,
polypropylene, cotton and pulp to have those fabrics itself

fabrics into antimicrobial and anti-fungus water prepared by mixing
one or one metal particles of gold, platinum, silver, germanium,
selenium and zinc so that both of fabrics and water have
antimicrobial and anti-fungus functions.
Technical Solution
[0073] According to this invention, to achieve above objectives,
the 1st objective provides the manufacture method of antimicrobial
and anti-fungus wet tissue with selected non-woven fabrics of
blended one or one materials of viscose rayon, polyester,
polyethylene, and polypropylene or cotton or pulp by mixing into
antimicrobial water which contains nano metal particles of one or
more than one of platinum, gold, silver, germanium, selenium and
zinc.
[0074] According to the second objective of this invention, the
manufacture method of antimicrobial and anti-fungus wet tissue
comprises a step of forming the antimicrobial and anti-fungus
fabrics by mixing one or more that one metal nano particles of
platinum, gold, silver, germanium, selenium, zinc, copper and
tungsten into blended fabrics of one or more than one out of
viscose rayon, polyester, polyethylene, polypropylene, cotton and
pulp, and a step of fabricating antimicrobial and anti-fungus
tissue by dipping the antimicrobial and anti-fungus fabrics into
distilled water or purified water.
[0075] According to the third objective of this Patent, it provides
the manufacturing method of antimicrobial and anti-fungus wet
tissue with selected antimicrobial and anti-fungus fabrics which is
formed with one or more than one nano metal particles out of gold,
platinum, germanium, selenium, zinc, copper and tungsten and
antimicrobial water which contains one of more than one of metal
particles out of gold, platinum, germanium, selenium, zinc, copper
and tungsten.
[0076] According to this patent, in the above-mentioned viscose
rayon manufacturing process as fabric materials, one or more than
one nano metal particles out of germanium, selenium, zinc, copper
and tungsten are added before spinning of rayon yarn, and process
with master batch chips or compounding chips produced by mixing one
or more than one nano metal particles out of above mentioned gold,
platinum, silver, germanium, selenium, zinc, copper and tungsten
with thermostatic plastic resin into above mentioned polyester,
polyethylene and polypropylene.
[0077] And then, spin the master batch chip treated materials after
mixing 3-10% ratio into its raw materials or spin 100% of treated
compounding chips.
[0078] Above cotton is dipped into above mentioned nano metal
contained liquid or mixed spin with the nano metal particles.
[0079] And the nano metal particles is mixed into water for
dispersion process of pulp materials, or mix above nano metal
particles into adhesive agent which is used in the process of pulp
to have certain thickness and form, or it is mixed with the method
of spraying above nano metal particles after the pulp is formed as
fabrics.
Advantageous Effects
[0080] As described in above, According to the manufacturing method
of antimicrobial and anti-fungus tissue based on this invention,
the first example can provide enough antimicrobial and anti-fungus
efficiency without color changes for long time as it is
manufactured hygienically with antimicrobial and anti-fungus water
and one or more than one of nano metal particles of gold, platinum,
silver, germanium, selenium and zinc into non-woven fabrics or
cotton fabrics or pulp which are relatively less contaminated.
[0081] In case of the second example, as there are still
possibility for the non-woven fabrics to be contaminated and
infected during the manufacturing process, transportation and
warehousing, and the non-woven fabrics can be the place where the
organic materials contained in the wet tissue can be the feeds to
bacteria and fungus to live, the increase of bacteria and fungus
from wet tissues can be inhibited for long period by dipping
antimicrobial and anti-fungus non-woven fabrics into distilled
water or purified water after providing antimicrobial and
anti-fungus function to raw fabrics of textile materials by mixing
one or more than one of nano metal particles out of gold, platinum,
silver, germanium, selenium and zinc.
[0082] And according to the third example, as the antimicrobial and
anti-fungus function is achieved by dipping antimicrobial and
anti-fungus textile fabrics of viscose rayon, polyester,
polyethylene, polypropylene and cotton which was mixed and formed
the web with one or more than one of nano metal particles out of
gold, platinum, silver, germanium, selenium, zinc, copper and
tungsten into antimicrobial and anti-fungus water which one or more
than one of nano metal particles out of gold, platinum, silver,
germanium, selenium and zinc, the propagation of microbes which
cause the contamination are inhibited from the manufacturing
process of non-woven fabrics as textile fabrics, and it is also
possible to inhibit the increase of bacteria and fungus even though
there are organic materials from the materials contained in wet
tissues.
[0083] Therefore, it is possible to manufacture multi-function wet
tissue that both of customers and manufacturers want regardless of
additive raw materials as it protects even the functional additives
of skin-beauty and moisturizer functions from being the feeds to
bacteria and fungus.
[0084] As the antimicrobial and anti-fungus function is added to
both of raw fabrics and manufacturing water for tissue in the third
example, it is possible to manufacture cheaper but high stability
wet tissues by reducing 30-50% in concentration level of nano metal
particles comparing to apply it to one of method of either raw
fabrics or manufacturing water for tissue even though individual
concentration level is different.
[0085] Accordingly, this invention considers contamination level of
the fabrics (non-woven fabric), hygienic level of its manufacturing
process and the contents of the organic additives which are being
used to manufacture wet tissues. It is possible to use nano metal
particles to either non-woven fabrics or manufacturing water for
wet tissue to manufacture wet tissues under this invention. Or, it
is possible to use the nano metal particles to each of these one
materials (fabrics and water) separately.
[0086] And it is possible to control different mixing ratio and
quantity of nano metal particles for wet tissue per its fabric
materials and water for tissue as shown in the above-mentioned
examples 1,2 and 3.
[0087] As the wet tissues manufactured with this invention does not
use chemical preservatives which can give irritation to skin, it
can provide of less irritation to skin of human-being as well as it
minimizes the skin irritation and provides safety wet tissues as
the chemical preservatives are not used even when many other
additives of moisturizer and natural organic materials are added to
manufacture multi function wet tissues.

BEST MODE
[0100] Now, preferred embodiments of this invention will be
described in detail with reference to the accompanying
drawings(that is, pictures).
[0101] At first, according to the first embodiment of this
invention, it applies to tissue manufacturing water of
antimicrobial and anti-fungus function in tissue fabric with nano
metal particles to guarantee antimicrobial and anti-fungus effects
without chemical preservatives or antimicrobial and anti-fungus
materials to manufacture wet tissues with raw tissue fabrics which
have certain measurement, tensile strength and flexibility.
[0102] Hopefully, the Tissue Fabrics applied to the first
embodiment of this invention does not limit to only non-woven
fabrics of less contamination possibility of bacteria infection
caused by external or internal reasons during its manufacturing
process, distribution and warehousing but includes also cotton
fabrics and pulps.
[0103] According to the first embodiment of this invention, the
nano metal particles mixed to tissue manufacturing water to have
antimicrobial and anti-fungus functions include one or more than
one of selected mixtures out of platinum, gold, silver, germanium,
selenium and zinc.
[0104] Referring to FIG. 1, the nano metal particles applied to
this invention to provide antimicrobial and anti-fungus functions,
the Platinum (Pt: refer to TEM picture of FIG. 1) has the function
of antimicrobial and deodorizer and recognized widely as functional
catalyst. In this invention, particle size of 1-50 nm with final
concentration level of 0.00001-0.0005 wt % (0.1-5 ppm) of the
weight to tissue manufacturing water is used.
[0105] The Gold (refer to TEM picture of FIG. 2) out of the
above-mentioned nano metal particles have not only antimicrobial
function but also inhibitive action against aggregation of nano
particles by direct contact, coupling and aggregation. In this
invention, particle size of 1-30 nm with final concentration level
of 0.00001-0.001 wt % (0.1-l0 ppm) is used.
[0106] And, the Silver (refer to FIG. 3, TEM picture and
distribution chart) as nano metal particles applied in this
invention provides antimicrobial and anti-fungus function and
particle size of 1-20 nm with final concentration of 0.0001-0.002wt
% (1-20 ppm) to weight of tissue water.
[0107] According to this invention, as the nano silver particles
may cause color contamination if it reacts to ultra violet light,
or it can be aggregated or precipitated if it reacts to remaining
sulfides which is used in the manufacturing process of viscose
rayon yarn, it is recommended to minimize to use 0.00001-0.002 wt %
(0.1-20 ppm).
[0108] As the Zinc (refer to FIG. 5, TEM picture) out of nano metal
particles applied to this invention shows antimicrobial effect at
30 ppm and anti-fungus effect with above 300 ppm, this invention is
using the zinc of 1-5 nm particle size with final concentration of
0.003-0.03 wt % (30-300 ppm) to tissue manufacturing water.
[0109] The Germanium (organic germanium: refer to TEM picture of
FIG. 6) as nano metal particles were proved through experiment that
it has functions of inhibiting increase of spore of mushrooms and
fungi.
[0110] According to this invention, germanium of 1-50 nm particle
size with final concentration of 0.0001-0.01 wt % (1-100 ppm) to
weight of tissue manufacturing water is used.
[0111] The Selenium (refer to TEM picture of FIG. 7) as nano metal
particles applied to this invention has been proved through
experiments that it shows antimicrobial effect against spore of
fungus bacteria with below 50 ppm.
[0112] According to this invention, selenium of 1-50 nm particle
size with final concentration of 0.0001-0.01 wt % (1-100 ppm) to
the weight of tissue manufacturing water is used.

[0113] Referring to the table 1, the hydrogen peroxide
(H.sub.2O.sub.2) {circle around (7)} is mixed of into tissue
manufacturing water which one or more than one of nano metal
particles out of platinum, gold, silver, germanium, selenium and
zinc is mixed. Hopefully, mix the hydrogen peroxide to be its
concentration 10-450 ppm (0.001-0.045%).
[0114] It is to minimize the color change problem, by having the
oxygen (O.sub.2) of hydrogen peroxide (H.sub.2O.sub.2) react, in
tissue fabrics caused by aggregation or reaction of nano particles
in the tissue manufacturing water.
[0115] The total concentration of the nano metal particles of the
above-mentioned platinum, gold, silver, germanium, selenium and

0.01wt % (100 ppm) even though more than one of the above-mentioned
nano metal particles are mixed with mixing rate of any

concentration is 0.003.about.0.1 wt % (30.about.1,000 ppm) to the
weight of tissue fabrics(non-woven fabrics).
[0131] The size of nano metal particles of the above-mentioned
germanium (Organic germanium, refer to the TEM picture of FIG. 6)
is 1-50 nm and the final concentration is 0.0001.about.0.03wt %
(1.about.300 ppm) to the weight of tissue fabrics(non-woven
fabrics).
[0132] The size of nano metal particles of the above-mentioned
selenium (refer to the TEM picture of FIG. 7) is 1-50 nm and the
final concentration is 0.0001.about.0.01 wt % (1.about.100 ppm) to
the weight of tissue fabrics(non-woven fabrics).
[0133] The size of nano metal particles of the above-mentioned
tungsten(W; wolfram)(refer to the TEM picture of FIG. 8) is 1-50 nm
and the final concentration is 0.001.about.0.03 wt % (10.about.300
ppm) to the weight of tissue fabrics(non-woven fabrics).
[0134] According to the second embodiment, it is possible to use
non-woven fabrics of nano metal particles mixed to any fabric
materials of non-woven fabrics of {circle around (1)}viscose rayon
{circle around (2)}polyester {circle around (3)}polyethylene
{circle around (4)}polypropylene {circle around (5)}cotton {circle
around (6)}pulp, or mixed yarn with proper mixing ratio of each
non-woven fabrics materials contained nano metal particles
selectively.
[0135] However, considering the possibility of aggregation caused
by reaction of nano metal particles of sulfide which is a raw
materials used in the manufacturing process, platinum, gold and
silver from above listed nano metal particles are not used for
viscose rayon.
[0136] And, considering the possibility of separation of nano metal
particles from pulp and cotton materials as mixing status is not
strong enough than the polymerization of nano particles and high
molecule polymer in pulp and cotton, the particles of copper and
tungsten are not used, which may give irritation to the skin
relatively. And use reduced quantity of silver of 0.0005-0.01 wt %
(5-100 ppm) and zinc of 0.003.about.0.05 wt % (30.about.500 ppm)
respectively to the weight of tissue fabrics.
[0137] On the other hand, to make the nano metal particles of the
above-mentioned metals to be mixed as shown in the table 2, the
mixing method of one or more than one of selected nano metal
particles from the above-mentioned platinum, gold, silver,
germanium, selenium, zinc, copper and tungsten into the
manufacturing process of {circle around (2)}polyester {circle
around (3)}Polyethylene(PE), {circle around (4)}plypropylene(PP)
out of {circle around (1)}viscose rayon {circle around
(2)}Polyester {circle around (3)}polyethylene(PE, {circle around
(4)}polypropylene(PP) {circle around (5)}Cotton {circle around
(6)}pulp is applied.
[0138] According to this invention, viscose rayon is produced by
adding one or more than one of selected nano metal particles from
the above-mentioned germanium, selenium, zinc and copper to the
side feeding process of extruder of materials just before spin the
fabric materials prepared.
[0139] In other words, Viscose is manufactured by mixing and
melting the cellulose compound
[(C.sub.6H.sub.9O.sub.4-OCS.sub.2Na)n] with carbon disulfide
(CS.sub.2) after producing alkali-cellulose
[(C.sub.6H.sub.9O.sub.4-ONa)n] through dipping, pressing and
pulverizing process after mixing sodium hydroxide (NaOH) into pulp.
It is manufactured by spinning the selected one or more than one of
the above-mentioned nano metal particles mixed in the side feeding
process.
[0140] According to this innovation, in case of not using carbon
disulfide (CS.sub.2) or using the nano metal particles produced
with increase quantity of stabilizers or additives to minimize the
reaction against sulfide in the manufacturing process of viscose,
it is suggested to manufacture antimicrobial and anti-fungus rayon
fabrics by mixing nano metal particles in the process of producing
viscose as it increases the dispersibility of final rayon fabrics
[(C.sub.6H.sub.10O.sub.5)n].
[0141] And according to this invention, in case of {circle around
(5)} Cotton, the method of spin mixed with nano metal particles or
the method of dipping cotton materials into the liquid contained
nano particles in the manufacturing process of non-woven fabric or
yarn.
[0142] For {circle around (6)}Pulp, the method of mixing above
mentioned nano metal particles selectively into manufacturing water
which is used for dispersing process of pulp materials in the pulp
manufacturing process, mixing the above-mentioned nano metal
particles to the adhesive agents mixed into manufacturing process
of pulp to have the pulp certain thickness and shape and mixing the
above selected nano metal particles by spraying nano particles
after pulp is formed as raw fabrics.
[0143] And according to this invention, {circle around
(2)}Polyester(PET), {circle around (3)}polyethylene(PE), {circle
around (4)}polypropylene(PP), as authorized to this applicant
suggested by Korean Patent No. 10-0599532 for each resin materials
to be mixed with high concentration nano metal particles,
master-batch chips or compounding chips are produced by mixing the
selected nano metal particles of platinum, gold, silver and etc.
with certain ration into thermostatic plastic resin which is raw
materials for plastic products.
[0144] Afterwards, the antimicrobial and anti-fungus yarns are
produced by mixing the treat master-batch or compounding chips
(3-10% of master-batch chips and 100% of compounding chips) to the
raw materials and spin.
[0145] In above process, the materials of antimicrobial and
anti-fungus {circle around (1)}viscose rayon, {circle around
(2)}polyester(PET), {circle around (3)}polyethylene(PE), {circle
around (4)}polypropylene(PP), {circle around (5)}cotton and {circle
around (6)}pulp which nano metal particles are treated to
selectively is used independently or as mixtures of more than one
of it. And those are a lied to manufacture textile fabrics
(specially non-woven fabrics) that require antimicrobial and
anti-fungus functions including wet tissues as an example.
[0146] And the total concentration of the nano metal particles used
for final raw fabrics of wet tissues is limited not to exceed 0.1
wt % (1,000 ppm to the weight of wet tissue when the nano metal
particles of platinum, gold, silver, germanium, selenium, zinc,
copper and tungsten independently or mixture of more than one are
mixed into above textile materials of {circle around (1)}viscose
rayon, {circle around (2)}polyester, {circle around
(3)}polyethylene(PE), polypropylene(PP), {circle around (5)}cotton
and {circle around (6)}pulp, and the wet tissues manufactured with
the textile materials independently or mixtures of more than one of
each raw fabric.
[0147] This is because that the antimicrobial and anti-fungus
functions become effective within the limit of 0.1 wt % (1,000 ppm)
to the weight of non-woven fabric as the final concentration to be
used even though the mixing rate is fixed with any combination when
more than one nano particles are mixed.
[0148] According to the second embodiment of this invention, it is
possible to manufacture antimicrobial and anti-fungus wet tissue
with general tissue manufacturing water (distilled or purified
water) by mixing selected one or more than one of nano metal
particles of gold, platinum, silver, germanium, selenium, zinc and
tungsten into textile materials to have antimicrobial and
anti-fungus functions to manufacture non-woven fabrics.
[0149] FIG. 10 is a SEM picture of the fiber of mixed spin of
silver as nano metal particles together with polypropylene, FIG. 11
is a SEM picture of the fiber of mixed spin of silver as nano metal
particles together with polyester and FIG. 12 is a SEM picture of
the fiber of mixed spin of silver as nano metal particles together
with viscose rayon based on this invention.
[0150] Followings are the explanation on the manufacturing method
of antimicrobial and anti-fungus wet tissues with the 3rd example
of this invention.
[0151] The first embodiment is the manufacturing method of
antimicrobial and anti-fungus wet tissue by dipping the non-woven
fabric into tissue manufacturing water that contain nano metal
particles assuming the non-woven fabric as raw textile fabric which
is treated well to have antimicrobial, anti-fungus and
antipollution functions.
[0152] The second example is the manufacturing method of
antimicrobial and anti-fungus wet tissue is by mixing nano metal
particles of antimicrobial and anti-fungus functions into non-woven
fabrics as raw fabrics, and then dipping the non-woven fabrics into
general tissue manufacturing water such as distilled or purified
water.
[0153] Under the third embodiment of this invention, the
antimicrobial and anti-fungus wet tissue is manufactured by having
the nano metal particles contained into both of fabrics and tissue
manufacturing water to gain better antimicrobial and anti-fungus
function economically compared to the method of mixing the nano
metal particles into one of non-woven fabrics or tissue
manufacturing water to gain antimicrobial and anti-fungus functions
as explained in the first and second embodiments.
[0154] Again, according to the third embodiment of this invention,
the first antimicrobial and anti-fungus functions are gained by
mixing the nano metal particles of antimicrobial and anti-fungus to
fabrics for wet tissue, and the secondary antimicrobial and
anti-fungus functions are gained by having the tissue manufacturing
water of antimicrobial and anti-fungus non-woven fabrics contain
nano metal particles of antimicrobial and anti-fungus
functions.
[0155] With the above-mentioned first and second embodiments, the
enough concentration needs to be considered to manufacture wet
tissues of enough antimicrobial and anti-fungus function, however,
with this third embodiment, the overall concentration of 30-50% of
nano metal particles which are used for tissue manufacturing water
or tissue fabrics of the first and second embodiments as the nano
metal particles are mixed into both of tissue fabrics and tissue
manufacturing water.
[0156] According to the third embodiment of this invention, the
nano metal particles to mix to non-woven fabrics as raw fabric
materials and tissue manufacturing water are selected one or
mixtures of one from gold, platinum, silver, germanium, selenium,
zinc, copper and tungsten.
[0157] As to the above-mentioned textile fabrics, as explained in
the second embodiment, the nano metal particles of one or mixture
of more than one from the above-mentioned gold, platinum, silver,
germanium, selenium, zinc, copper and tungsten are mixed into raw
fabrics of viscose rayon, polyester, polyethylene, polypropylene
and cotton.
[0158] According to the third embodiment of this invention, as to
the non-woven fabrics to manufacture wet tissue, as the type and
its ratio are decided per the mixing ration of fabrics of viscose
rayon, polyester, polyethylene, polypropylene and cotton, the
mixing rate of the nano metal particles can be lower than the
second embodiment considering that it is dipped into tissue
manufacturing water which already have antimicrobial and
anti-fungus function.
[0159] The table 3 in the below shows the mixing ratio of the nano
metal particles mixed into above-mentioned fabrics considering the
fact that the non-woven fabrics are mixed into antimicrobial and
anti-fungus fabric materials contained nano metal particles.

to TEM of FIG. 4) is 1-50 nm and its final concentration is
0.001.about.0.01 wt % ( 10.about.100 ppm) to the weight of
fabrics.
[0164] The nano particle size of the above-mentioned zinc (refer to
TEM of FIG. 5) is 1-50 nm and its final concentration is
0.003.about.0.03 wt % (30.about.300 ppm) to the weight of
fabrics.
[0165] The nano particle size of the above-mentioned organic
germanium (refer to TEM of FIG. 6) is 1-50 nm and its final
concentration is 0.0001.about.0.005 wt % (1.about.50 ppm) to the
weight of fabrics.
[0166] The nano particle size of the above-mentioned selenium
(refer to TEM of FIG. 7) is 1-50 nm and its final concentration is
0.0001.about.0.005 wt % (1.about.50 ppm) to the weight of
fabrics.
[0167] The nano particle size of the above-mentioned tungsten
(refer to TEM of FIG. 8) is 1-50 nm and its final concentration is
0.001.about.0.01 wt % (10.about.100 ppm) to the weight of
fabrics.
[0168] According to the third embodiment, same or similar to the
second embodiment, each fiber material of non-woven fabrics of
{circle around (1)}viscose rayon, {circle around (2)}polyester,
{circle around (3)}polyethylene, {circle around (5)}polypropylene,
{circle around (6)}cotton and pulp that are mixed with selected
nano metal particles per the ratio of the table 3, or form of
compound fiber of non-woven fabric material that contained selected
nano metal particles are possible to use to manufacture non-woven
fabrics.
[0169] In the third embodiment, considering the possibility of
aggregation by reaction of sulfide which is the material to
manufacture viscose rayon, the nano metal particles of platinum,
gold and silver are not used.
[0170] And, considering the possibility of separation of nano metal
particles from pulp and cotton materials as mixing status is not
strong enough than the polymerization of nano particles and high
molecule polymer in pulp and cotton, the particles of copper and
tungsten are not used, which may give irritation to the skin
relatively.
[0171] And, considering the high possibility of color change by
reaction to adhesive agents of pulp, the silver particles of
0.0005.about.0.002wt % (5.about.20 ppm) concentration to the weight
of fabrics are used considering the fact of using antimicrobial
tissue water together.
[0172] To make the above-mentioned nano metal particles mix as
shown in the table 3, the mixing method of selected one or mixture
of more than one from the above-mentioned gold, platinum, silver,
germanium, selenium, zinc, copper and tungsten into the
manufacturing process if the above-mentioned materials of {circle
around (1)} viscose rayon, {circle around (2)}polyester, {circle
around (3)}polyethylene , {circle around (4)}polypropylene, {circle
around (5)}cotton and pulp is used.
[0173] As explained in the second embodiment, viscose rayon is
manufactured by adding one or more than one of nano metal particles
of the above-mentioned germanium, selenium, zinc and copper to its
fabric materials before spin in the adding process of raw materials
to extruder.
[0174] According to this invention, in the case of that do not use
the Carbon Di Sulfide(CS.sub.2) or use the nano metal particles
produced by increased quantity of stabilizer or additives to
minimize the reaction against sulfide in the manufacturing process
of viscose, it is suggested that the nano metal particles are mixed
in the forming step of viscose, because it increases the
dispersibility of nano particles of the final rayon fiber
[(C.sub.6H.sub.10O.sub.5)n].
[0175] According to the third embodiment for {circle around
(5)}Cotton, in the manufacturing process of non-woven fabrics or
spin yarn out of cotton, it is applied that the method of dipping
the cotton materials into nano particles contained water or the
method of spinning with mixed nano particles.
[0176] For {circle around (6)}Pulp, selectively mixing method of
the above-mentioned nano metal particles into manufacturing water
which is used for dispersion of pulp material in the pulp
manufacturing process, or mixing method of the above-mentioned nano
metal particles into adhesive agents which are mixed into the
manufacturing process of pulp to certain thickness and shapes, or
the method of having the selected nano metal particles into the
pulp by spraying the nano particles after it is formed as shape of
fabrics are applied.
[0177] And for the above-mentioned {circle around (2)}polyester,
{circle around (3)}polyethylene, {circle around (4)} polypropylene,
as suggested in the afore-mentioned Korean Patent No.10-0599532,
after producing master batch chips or compounding chips by mixing
selected nano metal particles from platinum, gold and silver with
certain ratio into thermostatic plastic resins, the antimicrobial
and anti-fungus yarns is manufactured by mix and spin the master
batch chips with ratio of 3-10wt % to the weight of total amount
resins or spin 100% of the compounding chips.
[0178] The antimicrobial and anti-fungus materials of {circle
around (1)}viscose rayon, {circle around (2)}polyester, {circle
around (3)}polyethylene, {circle around (4)}polypropylene, {circle
around (5)}Cotton and {circle around (6)}Pulp through treatment of
nano metal particles selectively are used independently or as
combined. For example, it can be used to manufacture fabrics for
antimicrobial and anti-fungus products specially non-woven fabrics
including wet tissues.
[0179] And, the final concentration of nano metal particles of the
fabric materials which use each of the above-mentioned nano metal
particles of platinum, gold, silver, germanium, selenium, zinc,
copper and tungsten mixed into one or mixtures of more than one
fabric materials of above {circle around (1)}viscose rayon, {circle
around (2)}polyester(PET), {circle around (3)}polyethylene (PE),
{circle around (4)}polypropylene(PP), {circle around (5)} Cotton
and {circle around (6)} Pulp, and the final fabric of wet tissues
produced with one or mixtures of more than one of the fabric
materials shall not exceed 0.03 wt % (300 ppm) to the weight of
fabrics.
[0180] This is because of that it is possible to have enough
antimicrobial and anti-fungus function of final wet tissues as the
antimicrobial and anti-fungus tissue manufacturing water is able to
have the secondary functions in addition to preliminary
antimicrobial and anti-fungus functions within the limited
concentration of nano metal particles of 0.03 wt % (300 ppm) to the
non-woven fabrics finally used even though the mixing ratio of any
combination of more than one nano metal particles is decided.
[0181] In the tissue manufacturing water to achieve antimicrobial
and anti-fungus functions as shown in the table 3 of the third
embodiment of this invention, platinum, gold, silver, zinc,
germanium and selenium is mixed independently or more than one of
those selected material with the ratio shown in table 4. As for the
tissue manufacturing water of this third embodiment, relatively
lower mixing ratio is applied than above 1st example considering
that it is used as mixtures with antimicrobial an anti-fungus
fabrics.

[0182] According to the table 4, the size of nano platinum
particles mixed into the above-mentioned tissue manufacturing water
to have additional antimicrobial and anti-fungus to antimicrobial
and anti-fungus tissue fabrics shown in the table 3 is 1-50 nm and
the final concentration is 0.00001.about.0.0003 wt % (0.1.about.3
ppm) to the weight of tissue manufacturing water.
[0183] The size of nano gold particles mixed into the tissue
manufacturing water is 1-30 nm and its final concentration is
0.00001.about.0.0005 wt % (0.1.about.5 ppm) to the weight of tissue
manufacturing water.
[0184] The size of nano silver particles mixed into the tissue
manufacturing water is 1-20 nm and its final concentration is
0.00001.about.0.0001 wt % (0.1.about.10 ppm) to the weight of
tissue manufacturing water.
[0185] The size of nano zinc particles mixed into the tissue
manufacturing water is 1-50 nm and its final concentration is
0.0001.about.0.005 wt % (1.about.50 ppm) to the weight of tissue
manufacturing water.
[0186] The size of nano germanium particles mixed into the tissue
manufacturing water is 1-50 nm and its final concentration is
0.0001.about.0.005 wt % (1.about.50 ppm) to the weight of tissue
manufacturing water.
[0187] The size of nano selenium particles mixed into the tissue
manufacturing water is 1-50 nm and its final concentration is
0.0001.about.0.005 wt % (1.about.50 ppm) to the weight of tissue
manufacturing water.
[0188] And the final concentration of the nano metal particles
which make more than one nano metal particles of each of the
above-mentioned platinum, gold, silver, germanium, selenium and
zinc dip into the tissue manufacturing water of the third
embodiment 3 which already have bit of antimicrobial and
anti-fungus functions shall not exceed 0.005 wt % (50 ppm) to the
weight of tissue manufacturing water.
[0189] This is because of that it is possible to have enough
antimicrobial and anti-fungus function of final wet tissues as the
nano metal particles mixed in the non-woven fabrics get additional
antimicrobial and anti-fungus effects to the antimicrobial and
anti-fungus effect from the antimicrobial and anti-fungus tissue
manufacturing water is able to have the secondary functions in
addition to preliminary antimicrobial and anti-fungus functions
within the limited concentration of nano metal particles of 0.005
wt % (50 ppm) to the non-woven fabrics finally used even though the
mixing ratio of any combination of more than one nano metal
particles is decided.
[0190] This is because of that enough antimicrobial and anti-fungus
function can be obtained in the final wet tissue as the nano metal
particles contained in non-woven fabrics provide additional
antimicrobial and anti-fungus effects in addition to the effects
from the final concentration of 0.005 wt % (50 ppm) to the weight
of tissue manufacturing water even though the mixing rate of any
combination of the mixture of more than one of above nano metal
particles is decided.
[0191] The same manufacturing method as explained in the first and
second embodiments to select and use nano metal particles from the
raw materials of platinum, gold, silver, germanium, selenium, zinc,
copper and tungsten for non-woven fabrics and its manufacturing
water of the third embodiment to manufacture each nano particles,
additives such as reduction materials and stabilizers and the
manufacturing method to the specifications of each nano metal
particles are equally applied. (How to execute this invention)

of ignoring the possibility of non-woven fabric pollution itself by
impregnate non-woven fabric with tissue manufacturing water of
selected mixed nano metal particles of antimicrobial and
anti-fungus function as antimicrobial and anti-fungus fabrics under
this invention.
INDUSTRIAL APPLICABILITY
[0202] On the other hand, this invention is not limited to above
listed application examples but also possible to change its
applications subject to follow its technological basics of this
invention.
[0203] According to this invention, Even though the second
embodiment shows that it is possible to get antimicrobial and
anti-fungus function by melt-spinning one or mixture of more than
one of nano metal particles (of gold, platinum, silver, germanium,
selenium, zinc, copper and tungsten) into fabrics (of viscose
rayon, polyester, polyethylene, polypropylene, cotton and pulp) to
manufacture antimicrobial and anti-fungus non-woven fabrics, this
invention is not limited to only this embodiment.
[0204] As an another example, it is possible to make the non-woven
fabrics have antimicrobial and anti-fungus function by mixing
additives such as adhesive agent to one or mixture of nano metal
particles (of gold, platinum, silver, germanium, selenium, zinc,
copper and tungsten) in the manufacturing process of fabrics (of
viscose rayon, polyester, polyethylene, polypropylene, cotton and
pulp).
[0205] As an example, Chemical-bonding non-woven fabrics made of
viscose rayon and polyester or mixture of viscose rayon and
polyester can have antimicrobial and anti-fungus function by
dipping or spray method with one or mixtures of more than one of
above nano metal particles (of gold, platinum, silver, germanium,
selenium, zinc, copper and tungsten) mixed with adhesives (water
base adhesives, non-water base adhesives, soft type and hard type)
used to form the web.
[0206] As an other example, thermal-bonding non-woven fabrics of
polypropylene, blended yarn (PET-PE, PP-PE, PET-PP), viscose
rayon(hopefully polypropylene or mixture of blended yarn) and
polyester can get antimicrobial and anti-fungus function by forming
the web through combination of fabric structures by mixing one or
mixture of more than of above listed one nano metal particles
selected from gold, platinum, silver, germanium, selenium, zinc,
copper and tungsten to above fabrics of which fabric materials are
attached by heat or melted to the surface.
[0207] As another example, span-bond non-woven fabrics can be
manufactured to have antimicrobial and anti-fungus function by
using polyester, polypropylene or nylon chips and mix one or
mixture of more than one of selected nano metal particles from
above listed gold, platinum, silver, germanium, selenium, zinc,
copper and tungsten in the manufacturing process of melting and
spraying, and form the web.
[0208] And, air ray non-woven fabrics which are manufactured with
compressed air and adhesives to raw materials of fabric can have
antimicrobial and anti-fungus function by adding one or mixture of
more than one of selected nano metal particles from the
above-mentioned gold, platinum, silver, germanium, selenium, zinc,
copper and tungsten to above mentioned adhesives.
[0209] Spun Lace (Hydro-entanglement) can have antimicrobial and
anti-fungus function by adding one or mixture of more than one of
selected nano metal particles from the above-mentioned gold,
platinum, silver, germanium, selenium, zinc, copper and tungsten to
the water to spray to form the web after mixing one or mixture of
more than one of viscose rayon, polyester and polypropylene.
[0210] And, Melt-blown non-woven fabrics can have antimicrobial and
anti-fungus function by mixing one or mixture of more than one of
selected nano metal particles from the above-mentioned gold,
platinum, silver, germanium, selenium, zinc, copper and tungsten to
above melting fabric web in the manufacturing process of
homogeneous melting fabric web from spinning synthetic polymer and
formed micro fiber by high pressure and hot wind.
