Description
FIELD OF THE INVENTION
[0001] The present invention relates to an alkoxylated
polyethylenimine applicable for textile treatment in the textile
industry, especially for textile finishing. In particular, the
present invention relates to an alkoxylated polyethylenimine to be
used as an additive in textile treatment compositions, such as a
textile softening composition or a water-repellant treatment
composition in a textile finishing process. The present invention
further relates to a textile softening composition and a
water-repellant composition containing the same to be used in
textile industry, especially in the textile finishing process.
BACKGROUND OF THE INVENTION
[0002] In textile industry, especially during the finishing
process, textile treatment agents are applied, which provide
desired properties to the fabricated textile.
[0003] A textile softener is a treating agent for textile to make
the textile soft, fluffy and anti-static. A commonly used textile
softener, e.g. amino modified silicone oil, long carbon chain
alcohol, quaternary ammonium compounds, wax, ester, etc., can offer
soft hand feeling with economical cost.
[0004] A water-repellant agent, such as fluoro-containing
water-repellant agent or silicon-containing water-repellant agent,
is a treating agent for textile to provide the textile with
water-repellant properties. It can be used for textile-treating,
textile-finishing, and the like.
[0005] Furthermore, after being treated by the composition of the
present invention, the treated textile will have excellent washing
durability, which means that, after several times of washing
cycles, the treated textile will keep excellent performances such
as soft hand feeling or water repellence.
[0006] However, generally, textile softeners and water repellant
agents in the art have poor hydrophilicity.
[0007] Because of the hydrophobicity of textile softeners, treating
with these textile softeners will reduce the hydrophilicity of the
treated textile, thus lead to poor water absorption of the
textile.
[0008] Hydrophilic silicone oils have been developed in recent
years. Compared with amino modified silicone oil, hydrophilic
silicone oils exhibit an improved hydrophilicity. However,
producing several hydrophilic silicone oils is tedious, and the
hydrophilic silicone oil will adversely influence the hand of the
treated textile.
[0009] US 2011/0177994A1 discloses a fabric care composition
comprising a polyethylenimine as deposition aid. In this
application, polyethylenimine is used for improving the deposition
of a fabric care active with some examples being silicone or other
water-insoluble actives.
[0010] In the field of textile treating, especially in the
finishing process in textile treatment, there is still a need in
the art to provide a stable textile softening composition which
will improve hydrophilicity of textile at economical cost, while
the soft hand feeling of the textile being kept.
[0011] In the field of textile treating, there is as well still a
need in the art to provide a stable water-repellant composition
providing water-repellant properties to the textile.
[0012] Also, the treated textile will have excellent washing
durability, which means that, after several times of washing cycle,
the treated textile will keep excellent performances such as soft
hand feeling or water repellence.

polyethylenimine, when being used in a textile softening
composition or a water-repellant composition, can achieve the
desired results of the above.
[0014] The first aspect of the invention relates to an alkoxylated

of the alkoxylated polyethylenimine in textile treatment processes
in textile industry, particularly in the textile finishing
processes.

[0068] The alkoxylated polyethylenimine of the present invention
may be applied on nature fibre, e.g. cotton, and synthetic fibre,
e.g. polyester (such as PET, Polyglycolide or polyglycolic acid
(PGA), Polylactic acid (PLA), Polycaprolactone (PCL),
Polyhydroxyalkanoate (PHA), Polyhydroxybutyrate (PHB), Polyethylene
adipate (PEA), Polybutylene succinate (PBS),
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), Polyethylene
terephthalate (PET), Polytrimethylene terephthalate (PTT),
Polyethylene naphthalate (PEN), and so forth), polyamide,
polyethylene (PE), PP (polypropylene), and so on, which could be
woven, knitted or nonwoven fabric, together with other finishing
auxiliary (e.g. softener or water repellent) or alone.
[0069] For instance, the alkoxylated polyethylenimine of the
present invention may be applied to a PE/PP or a PE/Polyester (e.g.
PE/PET) bi-component nonwoven fabric, which is made from continuous
filament fibers and is non-linting or very low in linting, and
which comprises a sheath, that is polyethylene (PE) and a core,
that is polypropylene (PP) or a polyester (e.g. Polyethylene
terephthalate (PET), Polyglycolide or polyglycolic acid (PGA),
Polylactic acid (PLA), Polycaprolactone (PCL), Polyhydroxyalkanoate
(PHA), Polyhydroxybutyrate (PHB), Polyethylene adipate (PEA),
Polybutylene succinate (PBS),
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV),
Polytrimethylene terephthalate (PTT) or Polyethylene naphthalate
(PEN)). The core part provides strength and polyethylene sheath
part provides softness and low melting point.
[0070] The alkoxylated polyethylenimine of the present invention
may be applied in textile industry also for producing textiles for
specific purposes, e.g. including but not limited to for medical or
hygienic use (e.g. gauze, wound dressings, bandages, diapers,
sanitary napkins and so forth), and membrane industry, with the
function of improving hydrophilicity of substrates.
[0071] For instance, it improves the flow of the liquids e.g. into
an absorbent core, which is optionally made from cellulose fibers,
like a matrix of fluff material made from wood pulp, which may also
optionally additionally include wheat/corn based materials. The
liquids are absorbed by the capillaries in the void spaces between
the fibers and the surface tension angle between the fibers and the
water. An alternative to pulp is to use air laid synthetic fibers.
Also, cellulose acetate, e.g. used to make cigarette filters, has
been used in some absorbent products, as well as PP synthetic fiber
has also been attempted for absorbent core formation. For some
purposes, the absorbent core may further comprise chemical crystals
of absorbent polymers such as hydrogel, sodium polyacrylate,
polyacrylate absorbents, which may hold the liquids under
pressure.

Applied Finishing Treatment Methods
[0119] In the examples below, the fabrics are treated in an exhaust
process and in a padding process, which are common chemical
finishing treatments in textile industry.
[0120] Padding is one of the most common finishing technique, which
can be applied to carry out almost all wet finishing operations.
For the padding process, the dosage of softener is calculated by
weight of working solution, not by weight of fabric. Hence, the
concentration of the applied working solution is provided in g of
softener composition diluted per liter of water.
[0121] The treatment of fabrics in exhaustion liquor is another
possible finishing method, and is recommended when stable chemical
products are applied on the textile substrate. Here the
concentration of the applied softener is provided in percentage, %
"owf" (or o.w.f.) meaning based on the weight of fabric, which has
to be further diluted accordingly for the working solution.

[0166] Cotton Terry Towel was used as fabric to be treated in this
test. Each of the compositions was used and applied in dosage of 2%
owf (of weight fabric). The fabric liquid (work solution) ratio was
1:10, and the pH values of the compositions were in the range of
from 5.0 to 6.0.
[0167] The process was carried at 40.degree. C. for 20 min.

[0169] The data in table 18 showed that: Blank Cotton Terry Towel
had very fast water droplet absorbency (instant), however Hand
feeling was poor (see sample Blank); when being treated with amino
modified silicon oil softener, the Hand feeling of the treated
fabric was increased, the hydrophilicity was then decreased (2
seconds) (see fabric treated with composition 4-1-1); using only
Alkoxylated PEI-A or Alkoxylated PEI-B would not benefit to soft
hand feeling of the treated fabric (see fabrics treated with
composition 4-1-2 and composition 4-1-3) either; but when 20% amino
modified silicone oil softener was replaced by Alkoxylated PEI-A or
Alkoxylated PEI-B, the hydrophilicity was improved as compared with
the fabric treated with composition 4-1.
4.2. Test of the Fabrics Treated by the Compositions as Above in
Padding Process
[0170] PET fabric was used as fabric to be treated in this test.
Each of the compositions was used in dosage of 20 g/L. The pH
values of the compositions were in the range of 5.0 to 6.0.
[0171] The process was carried at pressure of 2.5 kg, and the %

[0172] The data in table 19 showed that: Blank PET fabric was
relative hydrophobic as compared with cotton, and the hand feeling
thereof was also poor (sample Blank); when being treated with amino
modified silicon oil softener, hand feeling of the treated PET
fabric was increased, and the hydrophilicity was then obviously
decreased (fabric treated with composition 4-1-1); when 20% amino
modified silicone oil softener was replaced by Alkoxylated PEI-A or
Alkoxylated PEI-B, the hydrophilicity of the treated fabric was
obviously improved as compared with the PET fabric treated with
composition 4-1-1.
4.3. Test of the Fabrics Treated by the Compositions Containing
Alkoxylated PEI-A, Hydrophilic Silicone Oil and/or Alkoxylated
PEI-B in Padding Process
[0173] The fabrics used in the test was woven PET which is
hydrophobic. Process parameters of the Padding Process were
provided as follows.
TABLE-US-00032 Fabric woven PET Equipment Rapid Padding Mangle

[0175] It can be seen that for PET woven fabrics, the fabric
treated with composition 4-2-4 showed better hydrophilic
performance than the fabrics treated with other compositions in
table 20.

[0205] It can be seen from table 26 and 27 that Blank PET fabric
(relative hydrophilic) had poor hand feeling; With PET Fabric
(relative hydrophilic) treated with Composition 5-1, hand feeling
got obviously improved, wicking height was also raised, as compared
with the blank sample; Composition 5-3 with 10% Alkoxylated PEI-B
and Composition 5-4 with 20% Alkoxylated PEI-A improved
hydrophilicity of the treated PET Fabric (relative hydrophilic)
without influencing hand feeling, as compared with the blank
sample.
Example 6
Effect of Alkoxylated PEI-B on Non-Woven Fabric Samples
[0206] To study the effect of Alkoxylated PEI-B on a non-woven
fabric, three samples of a non-woven fabric were prepared, wherein
the non-woven fabric was made of fiber composed of PE
(polyethylene) sheath and PET (poly(ethylene terephthalate))
core.
[0207] The three samples were provided in table 28. The non-woven
fabric used for preparing the three samples was obtained from the
same batch.
TABLE-US-00041 TABLE 28 Sample 6.1 non-woven fabric sample, not
treated Sample 6.2 non-woven fabric sample, treated with
Alkoxylated PEI-B Sample 6.3 non-woven fabric sample, treated with
oleic acid ethoxylate with HLB value 9 (nonionic surfactant)
6.1 Evaluation of the Diffusion Distance
[0208] The test was carried out on a sample as provided above on a
liquid absorbing substrate (made from a disposable diaper) at room
temperature.
[0209] The disposable diaper used in the example 6 had layers
sequentially as follows: [0210] a top sheet nonwoven layer; [0211]
a acquisition distribution layer (a PE/PET bi-component nonwoven
layer, with sheath being PE, and core being PET); [0212] absorbent
pad layer (consisted of (a) water-absorbing polymers and (b)
fibrous materials); [0213] bottom sheet nonwoven layer.
[0214] The disposable diaper was used as such and not treated.
[0215] In the test, the acquisition distribution layer of the
diaper was substituted by one of the above samples, thereby forming
a liquid absorbing device. 150 ml colored normal saline was poured
on the liquid absorbing device through a PVC sleeve (having an
inner diameter of 6 cm and an outer diameter of 7 cm) with one end
contacting directly to the top sheet layer of the liquid absorbing
device. Time recording started once the colored normal saline
reached to the top sheet layer of the liquid absorbing device, and
ended once the liquid level of the colored normal saline was
disappeared in the PVC sleeve. The obtained time was reported as
"Acquisition time" in table 29.
[0216] In addition, the longest diffusion distance of the colored
normal saline on the top sheet layer of the liquid absorbing device
and the shortest diffusion distance of the colored normal saline on
the top sheet layer of the liquid absorbing device were measured
and reported on the table 29.
[0217] After the diffusion of the colored normal saline on the top
sheet layer of the liquid absorbing device was finished, the
diffusion on the absorbent pad layer of the liquid absorbing device
was further studied. The longest diffusion distance of the colored
normal saline on the absorbent pad layer of the liquid absorbing
device and the shortest diffusion distance of the colored normal
saline on the absorbent pad layer of the liquid absorbing device
were further measured and reported on the table 29.
[0218] The test was carried out for each of the three samples
provided in table 28.
6.2 Evaluation of the Rewetting Property
[0219] Further to the test in section 6.1, rewetting property was
tested. A piece of dry filter paper was provided and weighted. The
weight of the dry filter paper was reported as the initial weight.
Then the dry filter paper was put on top of the top sheet layer of
the wetted liquid absorbing device obtained according to the
experimental procedure of section 6.1, and a 3.6 kg weight was
placed on the filter paper for 2 minutes. Then the weight was taken
away, and the weight of the wetted filter paper was measured as the
wetted weight.
[0220] The rewetting property was characterized according to the
wetted weight of the filter paper minus the initial weight of the
filter paper, which was reported as "rewet" in table 29.
Rewet=the wetted weight of the filter paper-the initial weight of
the filter paper.
[0221] The test was carried out for each of the three samples
provided in table 28. The dry filter paper used for testing each
sample was of the same condition.

absorbent pad layer (mm) .sup.1also generally referred to as
"strike through time (STT)", which may be defined as the time taken
for a known volume of liquid to pass through the nonwoven fabric
that is in contact with an underlying dry standard absorbent
pad.
Results:
[0222] It can be seen from table 29 that the Sample 6.2, which is
treated with Alkoxylated PEI-B, has the best results on longest
diffusion on top sheet layer and on both longest diffusion and
shortest diffusion on core. As for the shortest diffusion on top
sheet layer, the result obtained by sample 6.2 is as good as the
result obtained by sample 6.3.
6.3 Evaluation of the Diffusion Rate
[0223] The test was carried out at room temperature and controlled
humidity. A sample in table 28 was put on top of the center of a
tissue paper, wherein the tissue paper was balanced in terms of
weight and moisture beforehand.
[0224] 20 ml colored normal saline was poured to the sample through
a sleeve with one end contacting directly to the sample on the
tissue paper. Time recording started once the colored normal saline
reached to the surface of the tissue paper, and ended once the
colored normal saline was diffused to a marked line on the tissue
paper. The obtained time was reported on table 30.
[0225] The test was carried out for each of the three samples, with
all the conditions remaining the same.

s) 37 15 16
Results:
[0226] It can be seen from table 30 that the Sample 6.2, which is
treated with Alkoxylated PEI-B, has the shortest time for
diffusion.
