Description

FABRIC ENHANCEMENT TREATMENT
FIELD OF THE INVENTION
The present invention relates to textile and fabric treatment systems which can be suitably applied by the processor or manufacturer of textiles. The treatment systems of the present invention provide a wide range of enduring fabric benefits, inter alia, water absorbency, softness, anti-static, anti-abrasion, without the necessity to react with the fabric material itself.
BACKGROUND OF THE INVENTION
Cotton, rayon and other cellulose based fabrics. including polyester blends, are well suited for apparel. Cellulosic fabric is relatively robust to the rigors of mechanical abrasion whether due to wearing of the fabric or whether due to the laundering process. Cotton is hydrophilic, efficiently absorbing perspiration and providing a "breathable" feel to the wearer. Cotton is easily fabricated and dyed.
Manufacturers of cotton and other cellulosic material-comprising apparel, aside from dyeing, apply fabric finishes. Accordingly, manufacturers of fabric, especially fabric which is fashioned into an article of apparel. have developed various means for providing the fabric with lasting appearance benefits. Among the benefits which have been of importance is the softness.
This is typically accomplished by reacting the native fabric, cotton, inter alia, with softening compounds such as polymers (e.g. organo-silicones). emulsions of oils or wages (e.g. polyethylene emulsion) or surface-active agents. Because of the finishing with such a type of softening compound. treated fibers or fabric exhibit a soft feel to the user. However.
this softness benefit is often to the detriment of the water-absorbency. Hence. it is well known to the consumer that newly bought towels do not give a good absorbency of the water and therefore require at least one domestic wash before providing a good water-absorbency. Accordingly, there is a need for a treatment suitable for industry that provides a good water-absorbency while still not being detrimental to the softness performance.
Moreover. although many agents which provide the desired benefits can be added during the domestic laundry process on the final garment. they must compete for the fabric surface with surfactants. soil release agents, etc. and are therefore not necessarily uniformly or effectively applied.
There is a long felt need in the art for a teltile or fabric enhancement system which is suitably fabric substantive and which can be applied by the manufacturer or the fabricator to native fabric or to fabric after formation of an article of manufacture, which provides water-absorbency.
softness. anti-static. and anti-abrasion benefits.

SUMMARY OF THE INVENTION
The present invention meets the aforementioned needs in that it has been surprisingly discovered that textile finishes which provide enhanced fabric benefits can be applied by the fabric manufacturers or the garment fabricators to fabric, preferably cellulosic fiber containing fabric.
The finishes can be applied to the treated material at any point in the processing of the fabric.
The first aspect of the present invention relates to the treatment of textiles or fabric during any point in the manufacture process including after fabrication into an article of manufacture, inter alia, articles of apparel. The present invention relates to textile enhancement dispersion compositions comprising:
a) from about 0.05% by weight, of a softening compound having a transition temperature of less than 30 °C, b) optionally less than about 25% by weight, of a principal solvent, preferably said principal solvent has a ClogP of from about 0.15 to about l;
c) optionally from about 0.001 % to about 90% by weight, of one or more dye fixing agents;
d) optionally about 0.005% to about 1 % by weight, of one or more crystal growth inhibitors;
e) optionally from about 0.01 % to about 8% by weight. of a polyolefin emulsion or suspension;
f) optionally from about 0.01 % to about 0.2% by weight, of a stabilizer;
g) optionally from about 0.5'% to about 5% by weight. of a cationic surfactant; and h) the balance being a liquid carrier and optional adjunct ingredients.
The present invention further relates to a method for providing textile and fabric enhancement benefits, said method comprising the step of contacting textiles or fabric with the softening compound according to the invention or dispersion thereof or compositions of the present invention in industry. in particular at a point during manufacture or after fashioning into an article of apparel.
These and other objects. features. and advantages will become apparent to those of ordinan~ skill in the art from a reading of the following detailed description and the appended claims. All percentages. ratios and proportions herein are by weight. unless otherwise specified.

All temperatures are in degrees Celsius (° C) unless otherwise specified. All documents cited are in relevant part. incorporated herein by reference.

Still another essential element of the invention is a liquid carrier. Indeed.
by use of this carrier. a dispersion is obtained.
Liquid Carrier Another essential ingredient is a liquid carrier. Suitable liquid carriers are selected from water, organic solvents and mixtures thereof. The liquid carrier employed in the instant compositions is preferably at least primarily water due to its low cost relative availability. safety, and environmental compatibility. The level of water in the liquid carrier is preferably at least 50%, most preferably at least 60%, by weight ofthe carrier. Mixtures of water and low molecular weight, e.g., <200, organic solvent, e.g., lower alcohol such as ethanol, propanol, isopropanol or butanol are useful as the carrier liquid. Low molecular weight alcohols include monohvdric, dihydric (glycol. etc.) trihydric (glycerol. etc.), and higher polyhvdric (polyols) alcohols.
Preferably, the obtained dispersion will have a particle size of less than 100 micrometers.
as measured by laser diffraction (for example. a Malvern MastersizerS . from Malvern Instruments).

The fabric conditioning and fabric appearance compositions of the present invention. in addition to the softening compound and liquid carrier described herein above.
may optionally comprise the following optional ingredients.
Principal solvent The compositions of the present invention. preferably the isotropic liquid embodiments thereof may also optionally comprise a principal solvent. The level of principal solvent present in the compositions ofthe present invention is typically less than about 95%, preferably less than about 50%. more preferably less than about 25%. most preferably less than about 15% by weight.
Some embodiments of isotropic liquid embodiments of the present invention may comprise no principal solvent but may substitute instead a suitable nonionic surfactant.
The principal solvents of the present invention are primarily used to obtain liquid compositions having su~cient clarity and viscosity. Principal solvents must also be selected to minmize solvent odor impact in the composition. For example, isopropyl alcohol is not an effective principal solvent in that it does not serve to produce a composition having suitable viscosity.
Isopropanol also fails as a suitable principal solvent because it has a relatively strong odor.
Principal solvents are also selected for their ability to provide stable compositions at low temperatures, preferably compositions comprising suitable principal solvents are clear down to about 4° C and have the ability to fully recover their clarity if stored as low as about 7o C.
The principal solvents according to the present invention are selected base upon their octanol/water partition coefficient (P). The octanol/water partition coefficient is a measure of the ratio of the concentrations of a particular principal solvent in octanol and water at equilibrium.
The partition coe~cients are conveniently expressed and reported as their logarithm to the base 10;
loge.
The loge of many principal solvent species has been reported; for example, the Pomnona92 database. available from Daylight Chemical Information Systems.
Inc.(Daylight CIS), contains many. along with citations to the original literature.
However, the loge values are most conveniently calculated by the "CLOGP"
program, also available from Daylight CIS. This program also lists experimental loge values when they are available in the Pomona92 database. The "calculated IogP" (ClogP) is determined by the fragment approach of Hansch and Leo ( c~, A. Leo. in Comprehensive Medicinal Chemistry, Vol. 4, C.
Hansch, P. G. Sammens, J. B. Taylor and C. A. Ransden, Eds., p. 29~, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each HR species. and takes into account the numbers and types of atoms, the atom comiectivity, and chemical bonding. ClogP values are the most reliable and widely used estimates for octanol water partitioning. It will be understood by those skilled in the art that experimental log P values could also be used. Experimental log P values represent a less preferred embodiment of the invention. Where experimental log P values are used. the one hour log P values are preferred.
Other methods that can be used to compute ClogP include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 27a,21 (1987); Viswanadhan's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 29, 163 (1989): and Broto's method as disclosed in Eur. J.
Med. Chem. - Chim. Theor., 19, 71 (1984).
The principal solvents suitable for use in the present invention are selected from those having a CIogP of from about 0.15 to about 1, preferably from about 0.15 to about 0.64, more preferably from about 0.25 to about 0.62. most preferably form about 0.4 to about 0.6. Preferably the principal solvent is at least to some degree an asymmetric molecule, preferably having a melting, or solidification point which allows the principal solvent to be liquid at or near room temperature. Low molecular weight principal solvents may be desirable for some embodiments.
More preferred molecules are highly asymmetrical.

Gamble Co.; WO 97/03170 "Concentrated. Water Dispersible, Stable, Fabric Softening Composition", published January 30, 1997 and assigned to the Procter & Gamble Co.; and WO

Dve fixing agent Dye fixing agent is an optional component of the invention composition. Dye fixing agents.
or "fixatives". are well-known, commercially available materials which are designed to improve the appearance of dyed fabrics by minimizing the loss of dye from fabrics due to washing. Not included within this definition are components which are fabric softeners or those described hereinafter as amino-functional polymers.
Many dye fixing agents are cationic. and are based on various quaternized or otherwise cationically charged organic nitrogen compounds. Cationic fixatives are available under various trade names from several suppliers. Representative examples include: CROSCOLOR
PMF (July 1981, Code No. 7894) and CROSCOLOR NOFF (January 1988, Code No. 8544) from Crosfield;
INDOSOL E-50 (February 27, 1984, Ref. No. 6008.35.84; polyethyleneamine-based) from Sandoz: SANDOFIX TPS, which is also available from Sandoz and is a preferred polycationic fixative for use herein and SANDOFIX SWE (cationic resinous compound), REWIN
SRF, REWI1V SRF-O and REWIN DWR from CHT-Beitlich GMBH. Tinofix0 ECO, Tinofix~FRD
and Solfin~ available from Ciba-Geigy.

Other cationic dye fixing agents are described in "Aftertreatments for improving the fastness of dyes on textile fibres" by Christopher C. Cook (REV. PROG.
COLORATION Vol. 12, 1982). Dye fixing agents suitable for use in the present invention are ammouum compounds such as fatty acid - diamine condensates e.g. the hydrochloride. acetate, metosulphate and benzyl hydrochloride of oleyldiethyl aminoethylamide. olevlmethyl-diethylenediaminemethosulphate, monostearyl-ethylene diaminotrimethvlannnonium methosulphate and oxidized products of tertiary amines: derivatives of polymeric alkvldiamines, polyamine-cyanuric chloride condensates and aminated glycerol dichlorohvdrins.
Preferred dye fining agents are the cellulose reactive dye fixing agents.
The term "cellulose reactive dye fixing agent" is defined herein as "a dye fixative agent which reacts with the cellulose fibers upon application of heat or upon a heat treatment either in .sitz~ or by the formulator". The cellulose reactive dye fixing agents suitable for use in the present invention can be defined by the following test procedure.
Cellulose Reactivi~ Test (CRT) Four pieces of fabric which are capable of bleeding their dye (e.g. 10 x 10 cm of knitted cotton dyed with Direct Red 80) are selected. Two swatches arc used as a first control and a second control; respectively. The two remaining swatches are soaked for 20 minutes in an aqueous solution containing 1 % (w/w) of the cellulose reactive dye fixing agent to be tested. The swatches are removed and thoroughly dried. One of the treated swatches which has been thoroughly dried. is passed ten times through an ironing calender which is adjusted to a ''linen fabric" temperature setting. The first control swatch is also passed ten times through an ironing calendcr on the same temperature setting.
All four swatches ( the two control swatches and the two treated swatches, one of each which has been treated by the ironing calender) are washed separately in Launder-O-Meter pots under typical conditions with a coimnercial detergent used at the reconmiended dosage for '/Z hour at 60°C, followed by a thorough rinsing of 4 times 200 ml of cold water and subsequently line dried.
Color fastness is then measured by comparing the DE values of a new untreated swatch with the four swatches which have undergone the testing. DE values, the computed color difference. is defined in ASTM D2244. In general. DE values relate to the magnitude and direction of the difference between two psychophysical color stimuli defined by tristimulus values, or by chromaticitv coordinates and luminance factor, as computed by means of a specified set of color-difference equations defined in the CIE 1976 CIELAB opponent-color space, the Hunter opponent-color space, the Friele-Mac Adam-Chickering color space or any equivalent color space. For the purposes of the present invention. the lower the DE value for a sample, the closer the sample is to the un-tested sample and the greater the color fastness benefit.
As the test relates to selection or a cellulose reactive dye fixing agent, if the DE value for the swatch treated in the ironing step has a value which is better than the two control swatches, the candidate is a cellulose reactive dye fixing agent for the purposes of the invention.
Typically cellulose reactive dye fixing agents are compounds which contain a cellulose reactive moiety, non limiting examples of these compounds include halogeno-triazines, vinyl sulphones, epichlorhydrine derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products. polycarboxylates, glyoxal and glutaraldehyde derivatives; and mixtures thereof. Further examples can be found in "Textile Processing and Properties", Tyrone L. Vigo, at page 120 to 121. Elsevier ( 1997). which discloses specific electrophilic groups and their corresponding cellulose affinity.
Preferred hydroxyethylene .urea derivatives include dimethyloldihydroxyethylene, urea. and dimethyl urea glyoxal. Preferred formaldehyde condensation products include the condensation products derived from formaldehyde and a group selected from an amino-group, an imino-group, a phenol group, an urea group, a cyanamide group and an aromatic group.
Commercially available compounds among this class are Sandofix WE 56 ex Clariant, Zetex E ex Zeneca and Levogen BF
ex Bayer. Preferred polycarboxylates derivatives include butane tetracarboxilic acid derivatives.
citric acid derivatives, polyacrylates and derivatives thereof. A most preferred cellulosic reactive dye fixing agents is one of the hvdroxyethylene urea derivatives class connmercialized under the tradename of Indosol CR ex Clariant. Still other most preferred cellulosic reactive dye fixing agents are cormmercialized under the tradename Rewin DWR and Rewin WBS ex CHT R.

Crystal Growth Inhibition Test (CGIT) The suitability of a material to serve as a crystal growth inhibitor according to the present invention can be determined by evaluating in vitro the growth rate of certain inorganic micro-crystals. The procedure of Nancollas et al., described in "Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Charact., Vol 3, 77-102, (1980), incorporated herein by reference, is a method which is suitable for evaluating compounds for their crystal groWh inhibition. The graph below serves as an example of a plot indicating the time delay (t-lag) in crystal formation afforded by a hypothetical crystal growth inhibitor.

The observed t-lag provides a measure of the compound's efficiency with respect to delaying the growth of calcium phosphate crystal. The greater the t-lag, the more efficient the crystal growth inhibitor.
Exemplan~ Procedure Combine in a suitable vessel. 2.1M KCl (3~ mL), 0.0175M CaCh (~OmL), O.O1M
KH~P04 (~OmL). and de-ionized water (350mL). A standard pH electrode equipped with a Standard Calomel Reference electrode is inserted and the temperature adjusted to 37° C while purging of the solution of oxygen. Once the temperature and pH are stabilized.
a solution of the crystal growth inhibitor to be test is then added. A typical inhibitor test concentration is 1 x 10-6 M. The solution is titrated to pH 7.4 with O.O~M KOH. The mixture is then treated with ~ mL's of a hydroxyapatite slurry. The hvdroxyapatite slurry can be prepared by digesting Bio-Gel HTP
hydroxyapatite powder (100 g) in 1 L of distilled water the pH of which is adjusted to 2.~ by the addition of sufficient 6N HCI and subsequently heating the solution until all of the hydroxyapatite is dissolved (heating for several days may be necessary). The temperature of the solution is then maintained at about 22° C while the pH is adjusted to 12 by the addition of a solution of 50%
aqueous KOH. Once again the solution is heated and the resulting slurry is allowed to settle for two days before the supernatant is removed. 1.~ L of distilled water is added, the solution stirred, then after settling again for 2 days the supernatant is removed. This rinsing procedure is repeated six more time after which the pH of the solution is adjusted to neutrality using 2N HCI. The resulting slurry can be stored at 37°C for eleven months.
Crystal growth inhibitors which are suitable for use in the present invention have a t-lag of at least 10 minutes, preferably at least 20 minutes. more preferably at least ~0 minutes, at a concentration of 1 x 10-~M. Crystal growth inhibitors are differentiated form chelating agents by the fact that crystal growth inhibitors have a low binding affinity of heavy metal ions. i.e., copper.

The preferred polymers which comprise D units which are amide moieties are those which have the nitrogen atoms of the amide unit highly substituted so the nitrogen atoms are in effect shielded to a varying degree by the surrounding non-polar groups. This provides the polymers with an amphiphilic character. Non-limiting examples include polyvinyl-pyrrolidones, polyvinyloxazolidones, N,N-disubstituted polyacrylamides, and N,N-disubstituted polymethacrylamides. A detailed description of physico-chemical properties of some of these polymers are given in "Water-Soluble Synthetic Polymers: Properties and Behavior". Philip Molvneux, Vol. I, CRC Press. (1983) included herein by reference.
The amide containing polymers may be present partially hydrolyzed and/or crosslinked forms. A preferred polymeric compound for the present invention is polyvvrylpyrrolidone (PVP).

Polymers Comprising N-oxide Units Another D unit which provides dye transfer inhibition enhancement to the fabric abrasion reducing polymers described herein, are N-oxide units having the formula:
O
Ry ~ - R3 Rz wherein R', R', and R~ can be any hydrocarbyl unit (for the purposes of the present invention the term "hydrocarbyl" does not include hydrogen atom alone). The N-oxide unit may be part of a polymer, such as a polyamine, i.e., polyalkyleneamine backbone, or the N-oxide may be part of a pendant group attached to the polymer backbone. An example of a polymer which comprises an the N-oxide unit as a part of the polymer backbone is polyethyleneimine N-oxide. Non-limiting examples of groups which can comprise an N-oxide moiety include the N-oxides of certain heterocycles inter alia pyridine, pyrrole, imidazole, pyrazole, pyrazine, pyrimidinc, pyridazine, piperidine, pyrrolidine, pyrrolidone, azolidine, morpholine. A preferred polymer is poly(4-vinylpyriding N-oxide, PVNO). In addition, the N-oxide unit may be pendant to the ring. for example. aniline oxide.
N-oxide comprising polymers of the present invention will preferably have a ratio of N-oxidized amine nitrogen to non-oxidized amine nitrogen of from about I :0 to about 1:2, preferably to about I :1. more preferably to about 3:1. The amount of N-oxide units can be adjusted by the formulator. For example, the formulator may co-polymerize N-oxide comprising monomers with non N-oxide comprising monomers to arrive at the desired ratio of N-oxide to non N-oxide amino units, or the formulator may control the oxidation level of the polymer during preparation. The amine oxide unit of the polyamine N-oxides of the present invention have a Pk~
less than or equal to 10, preferably less than or equal to 7. more preferably less than or equal to 6. The average molecular weight of the N-oxide comprising polymers which provide a dye transfer inhibitor benefit to reduced fabric abrasion polymers is from about X00 daltons, preferably from about 100.000 daltons, more preferably from about 160.000 daltons to about 6,000,000 daltons, preferably to about 2,000,000 daltons, more preferably to about 360.000 daltons.

Pol~~rners Comprising Amide Units and N-oxide Units A further example of polymers which are fabric abrasion reducing polymers which have dye transfer inhibition benefits are polymers which comprise both amide units and N-oxide units as described herein above. Non-limiting examples include co-polymers of two monomers wherein the first monomer comprises an amide unit and the second monomer comprises an N-oxide unit. In addition, oligomers or block polymers comprising these units can be taken together to form the mixed amide/N-oxide polymers. However. the resulting polymers must retain the water solubility requirements described herein above.
Molecular weight For all the above polymer of the invention, it most preferred that they have a molecular weight in the range as described herein above. This range is typically higher than the range for polymers which render only dye transfer inhibition benefits alone. Indeed, the high molecular weight enables the abrasion occurring subsequent to treatment with the polymer to be reduced, especially in a later washing procedure. Not to be bound by theory, it is believed that that this benefit is partly due to the high molecular weight. thereby enabling the deposition of the polymer on the fabric surface and providing sufficient substantivity that the polymer is able to remain adhered to the fabric during the subsequent use and washing of the fabric. Further, it is believed that for a given charge density. increasing the molecular weight will increase the substantivity of the polymer to the fabric surface. Ideally the balance of charge density and molecular weight will provide both a sufficient rate of deposition onto the fabric surface and a su~cient adherence to the fabric during a subsequent wash cycle. Increasing molecular weight is considered preferable to increasing charge density as it allows a greater choice in the range of materials which are able to provide the benefit and avoids the negative impact that increasing charge density can have such as the attraction of soil and residue onto treated fabrics. It should be noted however that a similar benefit may be predicted from the approach of increasing charge density while retaining a lower molecular weight material.

However, any suitable clay/soil dispersent or anti-redepostion agent can be used in the laundry compositions of the present invention.
Electrolyte The fabric softening embodiments of the compositions of the present invention, especially clear. isotropic liquid fabric softening compositions, may also optionally.
but preferably comprise.
one or more electrolytes for control of phase stability, viscosity, and/or clarity. For example. the presence of certain electrolytes inter alia calcium chloride. magnesium chloride may be key to insuring initial product clarity and low viscosity, or may affect the dilution viscosity of liquid embodiments. especially isotropic liquid embodiments. Not wishing to be limited by theory, but only wishing to provide an example of a circumstance wherein the formulator must insure proper dilution viscosity. includes the following example. Isotropic or non-isotropic liquid fabric softener compositions can be introduced into the rinse phase of laundry operations via an article of manufacture designed to dispense a measured amount of said composition.
Typically the article of manufacture is a dispenser which delivers the softener active only during the rinse cycle. These dispensers are typically designed to allow an amount of water equal to the volume of softener composition to enter into the dispenser to insure complete delivery of the softener composition. An electrolyte may be added to the compositions of the present invention to insure phase stability and prevent the diluted softener composition from "gelling out" or from undergoing an undesirable or unacceptable viscosity increase. Prevention of gelling or formation of a "swelled". high viscosity solution insures thorough delivery of the softener composition.
However. those skilled in the art of fabric softener compositions will recognize that the level of electrolyte is also influenced by other factors inter alia the type of fabric softener active, the amount of principal solvent, and the level and type of nonionic surfactant. For example, triethanol amine derived ester quaternary amines suitable for use as softener actives according to the present invention are typically manufactured in such a way as to yield a distribution of mono-.
di-, and tri- esterified quaternary armnonium compounds and amine precursors.
Therefore. as in this example, the variability in the distribution of mono-. di-. and tri-esters and amines may predicate a different level of electrolyte. Therefore, the fornmlator must consider all of the ingredients. namely. softener active, nonionic surfactant. and in the case of isotropic liquids. the principal solvent type and level, as well as level and identity of adjunct ingredients before selecting the type and/or level of electrolyte A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of the Group IA and IIA metals of the Periodic Table of the elements, e.g., calcium chloride, sodium chloride, potassium bromide, and lithium chloride. The ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and later to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the desires of the formulator. Typical levels of salts used to control the composition viscosity are from about 20 to about 10,000 parts per million (ppn-1), preferably from about 20 to about x.000 ppm, of the composition.
Alkylene polyammonium salts can be incorporated into the composition to give viscosity control in addition to or in place of the water-soluble. ionizable salts above, In addition, these agents can act as scavengers, forming ion pairs with anionic detergent carried over from the main wash, in the rinse, and on the fabrics, and can improve softness performance.
These agents can stabilized the viscosity over a broader range of temperature. especially at low temperatures, compared to the inorganic electrolytes. Specific examples of alkylcne polyamlnonium salts include L-lysine, monohydrochloride and 1.5-dianunonium 2-methyl pentane dihydrochloride.
Cationic Charge Boosters The compositions or the present invention may optionally comprise one or more cationic charge boosters. especially to the rinse-added fabric softening embodiments of the present invention. Typically, ethanol is used to prepare many of the below listed ingredients and is therefore a source of solvent into the final product formulation. The formulator is not limited to ethanol. but instead can add other solvents inter alia Iiexyleneglycol to aid in formulation of the final composition. This is especially true in clear. translucent, isotropic compositions.
The preferred cationic charge boosters of the present invention are described herein below.
