Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application Serial No. 60/372,877, filed Apr. 16, 2002.
TECHNICAL FIELD
[0002] The present invention relates to textile mill applications
of certain cellulosic based polymer or oligomer materials which
impart appearance and integrity benefits to fabrics and textiles
during laundering and in-wear. The applications can be stand alone
or incorporated into traditional textile mill processes such as
dyeing and finishing.
BACKGROUND OF THE INVENTION
[0003] It is, of course, well known that alternating cycles of
using and laundering fabrics and textiles, such as articles of
clothing and apparel, will inevitably adversely affect the
appearance and integrity of the fabric and textile items so used
and laundered. Fabrics and textiles simply wear out over time and
with use. Laundering of fabrics and textiles is necessary to remove
soils and stains which accumulate therein and thereon during
ordinary use. However, the laundering and in-wear, over many
cycles, can accentuate and contribute to the deterioration of the
integrity and the appearance of such fabrics and textiles.
[0004] Deterioration of fabric integrity and appearance can
manifest itself in several ways. Short fibers are dislodged from
woven and knit fabric/textile structures by the mechanical action
of laundering and abrasion/rubbing during in-wear. These dislodged
fibers may form lint, fuzz or "pills" which are visible on the
surface of fabrics and diminish the appearance of newness of the
fabric. Further, repeated laundry-wear cycles of fabrics and
textiles, can remove dye from fabrics and textiles and impart a
faded, worn out appearance as a result of diminished color
intensity, and in many cases, as a result of changes in hues or
shades of color.
[0005] Given the foregoing, there is clearly an ongoing need to
identify materials which could be added to textile mill
applications which reduce or minimize the tendency of
fabric/textiles to deteriorate in appearance during laundering and
in-wear. Any applications of such materials should, of course, be
able to benefit fabric appearance and integrity without unduly
interfering with other fabric/textile properties such as fabric
feel or hand feel, draping, softness, smoothness, etc. The present
invention is directed to the use of cellulosic based polymer or
oligomer materials in textile mill application which perform in
this desired manner.
SUMMARY OF THE INVENTION
[0006] Cellulosic based polymer or oligomer materials which are
suitable for textile mill applications and provide the desired
fabric appearance and integrity benefits can be characterized by
the following general formula: 1
[0007] wherein each R is selected from the group consisting of
R.sub.2, R.sub.C, and 2
[0008] wherein:
[0009] each R.sub.2 is independently selected from the group
consisting of H and C.sub.1-C.sub.4 alkyl;
[0010] each R.sub.C is 3
[0011] wherein each Z is independently selected from the group
consisting of M, R.sub.2, R.sub.C, and R.sub.H;
[0012] each R.sub.H is independently selected from the group
consisting of C5-C.sub.20 alkyl, C.sub.5-C.sub.7 cycloalkyl,
C.sub.7-C.sub.20 alkylaryl, C.sub.7-C.sub.20 arylalkyl, substituted
alkyl, hydroxyalkyl, C.sub.1-C.sub.20 alkoxy-2-hydroxyalkyl,
C.sub.7-C.sub.20 alkylaryloxy-2-hydroxyalkyl,
(R.sub.4).sub.2N-alkyl, (R.sub.4).sub.2N-2-hydroxyalkyl,
(R.sub.4).sub.3 N-alkyl, (R.sub.4).sub.3 N-2-hydroxyalkyl,
C.sub.6-C.sub.12 aryloxy-2-hydroxyalkyl, 4
[0013] each R.sub.4 is independently selected from the group
consisting of H, C.sub.1-C.sub.20 alkyl, C.sub.5-C.sub.7
cycloalkyl, C.sub.7-C.sub.20 alkylaryl, C.sub.7-C.sub.20 arylalkyl,
aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, piperidinoalkyl,
morpholinoalkyl, cycloalkylaminoalkyl and hydroxyalkyl;
[0014] each R.sub.5 is independently selected from the group
consisting of H, C.sub.1-C.sub.20 alkyl, C.sub.5-C.sub.7
cycloalkyl, C.sub.7-C.sub.20 alkylaryl, C.sub.7-C.sub.20 arylalkyl,
substituted alkyl, hydroxyalkyl, (R.sub.4).sub.2N-alkyl, and
(R.sub.4).sub.3 N-alkyl;
[0015] wherein:
[0016] M is a suitable cation selected from the group consisting of
Na, K, 1/2Ca, and 1/2Mg;
[0017] each x is from 0 to about 5;
[0018] each y is from about 1 to about 5; and
[0019] provided that:
[0020] the Degree of Substitution for group R.sub.H is between
about 0.0001 and 0.1, more preferably between about 0.0005 and
0.05, and most preferably between about 0.0008 and 0.01;
[0021] the Degree of Substitution for group R.sub.C wherein Z is H
or M is between about 0.2 and 2.0, more preferably between about
0.3 and 1.0, and most preferably between about 0.4 and 0.7;
[0022] if any R.sub.H bears a positive charge, it is balanced by a
suitable anion; and
[0023] two R.sub.4's on the same nitrogen can together form a ring
structure selected from the group consisting of piperidine and
morpholine.
[0024] The cellulosic based polymer or oligomer materials defined
above can be used as an additive in dyeing, dyeing aftertreatments,
softener finishing, hand building finishing, durable press
finishing, antibacterial finishing, soil release finishing, and
even mechanical finishings, etc. The materials can be applied onto
yarns/fabrics/textiles/garments via pad-dry processes or exhaustion
methods
[0025] The amount of the cellulosic based fabric treatment
materials of the present invention needed in the textile mill
applications to provide the best fabric appearance benefits depends
on many factors such as yarn/fabric constructions, types of textile
processes and types of textile equipment. Based on weight of
fabrics, from about 0.005% to 10% of the cellulosic based materials
is needed to impart fabrics with the best fabric appearance and
integrity. The preferred amount is from about 0.01% to 3% based on
weight of fabrics treated with the cellulosic based materials. Such
benefits can include improved overall appearance, pill/fuzz
reduction, antifading, improved abrasion resistance, and/or
enhanced softness.
[0026] All percentages, ratios and proportions herein are on a
weight basis unless otherwise indicated. All documents cited herein
are hereby incorporated by reference.
BRIEF DESCRIPTION OF THE DRAWINGS
[0027] FIG. 1 is an example of the pad-dry treatment process.
[0028] FIG. 2 is an example of the exhaustion treatment method.
DETAILED DESCRIPTION OF THE INVENTION
[0029] A) Cellulosic Based Polymer or Oligomer Materials
[0030] The essential component of the compositions of the present
invention comprises one or more cellulosic based polymer or
oligomer. Such materials have been found to impart a number of
appearance benefits to fabrics and textiles after applied onto
fabrics during textile mill applications. Such fabric appearance
benefits can include, for example, improved overall appearance of
the laundered fabrics, reduction of the formation of pills and
fuzz, protection against color fading, improved abrasion
resistance, etc. The cellulosic based fabric treatment materials
used in the compositions and methods herein can provide such fabric
appearance benefits with acceptably little or no loss in other
preferred textile properties such as fabric feel/hand, draping,
softness, smoothness, etc.
[0031] As will be apparent to those skilled in the art, an oligomer
is a molecule consisting of only a few monomer units while polymers
comprise considerably more monomer units. For the present
invention, oligomers are defined as molecules having an average
molecular weight below about 1,000 and polymers are molecules
having an average molecular weight of greater than about 1,000. One
suitable type of cellulosic based polymer or oligomer fabric
treatment material for use herein has an average molecular weight
of from about 5,000 to about 2,000,000, preferably from about
50,000 to about 1,000,000.

Na, K, 1/2Ca, and 1/2Mg;
[0043] each x is from 0 to about 5;
[0044] each y is from about 1 to about 5; and
[0045] provided that:
[0046] the Degree of Substitution for group R.sub.H is between
about 0.0001 and 0.1, more preferably between about 0.0005 and
0.05, and most preferably between about 0.0008 and 0.01;
[0047] the Degree of Substitution for group R.sub.C wherein Z is H
or M is between about 0.2 and 2.0, more preferably between about
0.3 and 1.0, and most preferably between about 0.4 and 0.7;
[0048] if any R.sub.H bears a positive charge, it is balanced by a
suitable anion; and
[0049] two R.sub.4's on the same nitrogen can together form a ring
structure selected from the group consisting of piperidine and
morpholine.
[0050] The "Degree of Substitution" for group R.sub.H, which is
sometimes abbreviated herein "DSRH", means the number of moles of
group R.sub.H components that are substituted per anhydrous glucose
unit, wherein an anhydrous glucose unit is a six membered ring as
shown in the repeating unit of the general structure above.
[0051] The "Degree of Substitution" for group R.sub.C, which is
sometimes abbreviated herein "DSRC", means the number of moles of
group R.sub.C components, wherein Z is H or M, that are substituted
per anhydrous glucose unit, wherein an anhydrous glucose unit is a
six membered ring as shown in the repeating unit of the general
structure above. The requirement that Z be H or M is necessary to
insure that there are a sufficient number of carboxy methyl groups
such that the resulting polymer is soluble. It is understood that
in addition to the required number of R.sub.C components wherein Z
is H or M, there can be, and most preferably are, additional
R.sub.C components wherein Z is a group other than H or M.
[0052] Other suitable cellulosic based polymer and/or oligomer
materials are described in WO 97/31950 published on Sep. 4, 1997
and WO 98/56825 published Dec. 17, 1998.
[0053] The production of materials according to the present
invention is further defined in the Examples below.
[0054] B) Textile Mill Applications
[0055] The cellulosic based polymer or oligomer materials defined
above can be used as an additive in dyeing, dyeing aftertreatments,
softener finishing, hand building finishing, durable press
finishing, soil release finishing, antibacterial finishing and even
mechanical finishings, etc. The materials can be also used either
by themselves alone or in conjunction with other textile additives
such as but not limited to wetting agents, chelating agents, pH
control agents, softeners, soil release agents, water repellants,
dye fixatives, durable press finishing agents, antibacterial
agents, etc. With regard to the textile processing process, the
cellulosic based polymer or oligomer materials are commonly
utilized during the dyeing and/or finishing stages
[0056] The materials can be applied onto
yarns/fabrics/textiles/garments via both pad-dry processes and
exhaustion methods as shown in FIGS. 1 and 2 respectively or via
spray application (not shown). The materials can be applied to
woven fabric, knit fabric, non-woven fabric, or combinations
thereof. The pad-dry process is common for the dyeing and finishing
of woven fabrics. No curing is necessary to fix the materials onto
fabrics although they are safe to go through high temperature
curing processes. Examples of high temperature curing processes
include but are not limited to finishes such as durable press
finishes and antibacterial finishes.
[0057] The exhaustion method is commonly used to treat knit fabrics
in the textile mill applications although some knit fabrics may be
treated in the pad-dry process.
[0058] The amount of the cellulosic based fabric treatment
materials of the present invention needed in the textile mill
applications to provide the best fabric appearance benefits depends
on many factors such as yarn/fabric constructions, types of textile
processes and types of textile equipment. Based on the weight of
the fabric, from about 0.005% to 10% of the cellulosic based
materials is needed to impart fabrics with the best fabric
appearance and integrity. The preferred amount is from about 0.01%
to 3% based on the weight of the fabric treated with the cellulosic
based materials. Such benefits can include improved overall
appearance, pill/fuzz reduction, antifading, improved abrasion
resistance, and/or enhanced softness.
[0059] With regard to the pad-dry process, referring to FIG. 1, the
concentration of the cellulosic based materials in the padding
solution 20 should be determined by wet pick-up. For example, 1% of
the aqueous solution is needed in the padding bath 40 if the wet
pick-up is controlled as 100% based on the weight of the fabric 10
and 1% of the cellulosic based materials are needed to deliver the
fabric 10 appearance and integrity benefits.
[0060] Referring to FIG. 2, for the exhaustion method, the amount
of the cellulosic based materials added into the exhaustion bath 60
is determined by the weight of the fabric 10. A non-limiting
example would be, if a 1% add-on level of the cellulosic based
materials to the fabric 10 is desired, this would be accomplished
for example by adding 1 kg of the cellulosic based materials to the
exhaustion bath 60 to treat 100 kg of fabric 10.
[0061] The pH range for fabric treatment is preferably from about 3
to 12 and more preferably from about 4 to 10.

Synthesis of Modified CMC Materials
[0066] The carboxylation of cellulose to produce CMC is a procedure
that is well known to those skilled in the art. To produce the
modified CMC materials of this invention, one adds during the CMC
making process the material, or materials, to be substituted. An
example of such as procedure is given below. This same procedure
can be utilized with the other substituent materials described
herein by replacing the hexylchloride with the substituent
material, or materials, of interest, for example, cetylchloride.
The amount of material that should be added to the CMC making
process to achieve the desired degree of substitution will be
easily calculated by those skilled in the art in light of the
following Examples.
Synthesis of Hexylether of CMC
[0067] This example illustrates the preparation of a carboxymethyl
hydrophobically modified carboxymethyl cellulose and is
representative of preparation of all of the cellulose ether
derivatives of this invention.
[0068] Cellulose (20 g), sodium hydroxide (10 g), water (30 g), and
ethanol (150 g) are charged into a 500 ml glass reactor. The
resulting alkali cellulose is stirred 45 minutes at 25.degree. C.
Then monochloroacetic acid (15 g) and hexylchloride (1 g) are added
and the temperature raised over time to 95.degree. C. and held at
95.degree. C. for 150 minutes. The reaction is cooled to 70.degree.
C., and then cooled to 25.degree. C. Neutralization is accomplished
by the addition of a sufficient amount of nitric acid/acetic acid
to achieve a slurry pH of between 8 and 9. The slurry is filtered
to obtain a hexylether of CMC.
