TEXTILE MILL APPLICATIONS OF CELLULOSIC BASED POLYMERS TO
PROVIDE APPEARANCE AND INTEGRITY BENEFITS TO FABRICS DURING
LAUNDERING AND IN-WEAR
TECHNICAL FIELD
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
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.
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.
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.

processes or
exhaustion methods
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

reduction, antifading,
improved abrasion resistance, and/or enhanced softness.
All percentages, ratios and proportions herein are on a weight basis unless
otherwise
indicated. All documents cited herein are hereby incorporated by reference.

DETAILED DESCRIPTION OF THE INVENTION
A) Cellulosic Based Polymer or Oli~omer Materials
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.
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.

97/31950 published on September 4, 1997 and WO 98/56825 published December 17,
1998.
The production of materials according to the present invention is further
defined in the
Examples below.

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 xepellants, 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
The materials can be applied onto yarns/fabrics/textiles/garments via both pad-
dry
processes and exhaustion methods as shown in Figures 1 and 2 respectively or
via spray
application (not shown). The materials can be applied to woven fabric, lrnit
fabric, nonwoven
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.
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.
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.
With regard to the pad-dry process, referring to Figure 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.
Referring to Figure 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

WO 03/089711 PCT/US03/11529
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.
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
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
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.

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°C. Then
monochloroacetic acid (15 g) and hexylchloride (1 g) are added and the
temperature raised over
time to 95°C and held at 95°C for 150 minutes. The reaction is
cooled to 70°C, and then cooled
to 25°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.
