Description

FABRIC MAINTENANCE COMPOSITIONS COMPRISING CERTAIN CATIONICALLY
CHARGED FABRIC MAINTENANCE POLYMERS
FIELD OF THE INVENTION
The present invention relates to fabric dye maintenance compositions which comprise one or more dye maintenance compounds which can be oligomers, polymers, co-polymers, and the like which comprise one or more monomers which results in the final dye maintenance compound having a net positive charge. Compositions comprising the dye maintenance polymers of this invention impart appearance and integrity benefits to fabrics and textiles treated with solutions formed from such compositions.
BACKGROUND OF THE INVENTION
It is, of course, well known that alternating cycles of using and laundering fabrics and textiles, such as articles of worn 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 operation itself, 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. 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 laundering of fabrics and textiles, especially with bleach-containing laundry products, 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 fabric treatment products, specifically to rinse added fabric conditioners, pre-wash spray on compositions, pre-soak compositions as well as after wash or between wash malodor

2 control or fabric re-freshening compositions, materials which would associate themselves with the fibers of the fabrics and textiles thereby reducing, abating, or minimizing the tendency of the fabric/textiles to deteriorate in appearance. Any such fabric treatment/fabric maintenance composition additive material should, of course, be able to benefit fabric appearance and integrity without unduly interfering with the ability of the balance of laundry products to perform their intended function. The present invention is directed to the use of dye maintenance polymers in fabric treatment and fabric enhancement compositions which perform in this desired manner.
SUMMARY OF THE INVENTION
The present invention meets the aforementioned need in that it has been surprisingly discovered that fabric which is treated, and subsequently re-treated with the compositions of the present invention, will resist normal fading and color loss without regard to the circumstances, inter alia, due to mechanical wear and abrasion. In addition, fabric which has not been treated can have the loss of fabric dye attenuated by adding the compositions of the present invention to the laundry cycle as an adjunct via pre-soak, rinse additive, etc. The compositions of the present invention can be added is any manner, inter alia, as part of a formulation or as a separate composition.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to attenuation and/or abatement of fabric appearance loss.
The compositions of the present invention comprise a cationic polymer or co-polymer which acts together with a low molecular weight fabric enhancement polyamine, fabric softness agent (crystal growth inhibitor) and dye fixing agent to provide protection to fabric from appearance loss which is primarily due to mechanical loss. Another aspect of the present invention relates to a composition which comprises a cationic polymer or co-polymer which acts together with a low molecular weight fabric enhancement polyamine, fabric softness agent (quaternary ammonium fabric softener active), dye fixing agent, and one further enhancement agent, inter al:a, a stabilizer, co-solvent. Yet another aspect of the present invention relates to a composition which comprises a cationic polymer or co-polymer which acts together with a low molecular weight WO 00/56848 CA 02365282 2001-08-31 pCT~S00/08030 fabric enhancement polyamine, fabric softness agent (crystal growth inhibitor) and quaternary ammonium fabric softness agent, and dye fixing agent. The normal abrasive destruction of the fabric surface removes the surface layers of fabric which are dyed. Especially in the case of cotton fabric, below this layer of dyed fabric is the less dyed, then non-dyed fabric. As wears a "washed looked" develops which is due to the abrasive destruction of fabric and the subsequent loss of the weakened fabric fiber in the laundry cycle.
It has been surprisingly discovered that the combination of elements which comprise the compositions of the present invention modify the surface of fabric, especially cellulosic fabric and ameliorate many of the conditions which enhance fabric fiber surface wear and subsequent loss. The compositions of the present invention also soften the fabric surface making the fibers less abrasive and thereby reducing the level of friction between the fabric and surfaces in which the garment comes into contact. This change in surface condition can nullify many of the conditions which contribute to fabric damage and hence attenuate, and in some cases, abate fabric damage and therefore the concomitant loss of color.
The compositions of the present invention can be used for a stand alone treatment of fabric wherein the compositions are added as ingredients to a compatible fully formulated rinsed additive, laundry additive or pre-soak all of which are used together with fabric softeners, laundry detergent compositions and the like. The compositions of the present invention, either as a stand alone treatment or as a system, are suitable for providing a method for treating fabric and subsequently attenuating or abating the loss of color due to mechanical abrasion and removal of the top layer of dyed fabric.
Alternatively, the compositions comprise a fabric color integrity system. The systems of the present invention are used as an initial treatment of fabric by the manufacturer of either the fabric from which apparel is made or the fully formed article of manufacture (apparel).
However, if the fabric is not pre-treated by the manufacturer, suitable protection is afforded to the fabric wherein the consumer applies the system to fabric during laundering. The systems of the present invention can be used at any point during the lifetime of apparel to abate the loss of color from fabric.
The following is a detailed description of the essential elements of the present invention.

A non-limiting example of an indirect Z unit which can be made to form a cationic charge in situ is the -NHCHO unit, formamide. The formulator can prepare a polymer or co-polymer comprising formamide units some of which are subsequently hydrolyzed to form vinyl amine equivalents.

In general, the polyamines are either linear polyamines or cyclic polyamines.
Linear Polyamines The enhanced fabric appearance compositions of the present invention may comprise one or more polyalkyleneimines which have backbones comprising CZ-C6 alkylene units, however, the backbones must comprise at least one C3-C6 alkylene unit, preferably the linear polyamines have each backbone unit comprising a C3-C6 alkylene unit.
The polyamines of the present invention have the formula:

(R1)ZN-R-[N-R]n N(R~)2 wherein each R is independently CZ-C6 linear alkylene, C3-C6 branched alkylene, and mixtures thereof; preferably the backbone is a mixture of ethylene, 1,3-propylene, 1,3-propylene, 1,4 butylene, 1,6-hexylene, more preferably a mixture of ethylene and 1,3-propylene, most preferably the backbone comprises only 1,3-propylene units.
R' is hydrogen; C,-C,2 alkyl, preferably C,-Cg alkyl, more preferably C,-C4 alkyl;

-~3~)W R4 wherein R3 is CZ C6 linear alkylene, C3-C6 branched alkylene, or mixtures thereof; preferably ethylene, mixtures of ethylene and 1,2-propylene, 1,2-butylene, preferably ethylene, 1,2-propylene. R4 is hydrogen, C,-C6 alkyl, or mixtures thereof; preferably hydrogen or methyl, more preferably hydrogen. The index m is from 1 to 4, however, the value of m is predicated on the desired fabric enhancement benefit sought by the formulator. For example, the level of bleach protection varies over the value of m. Also, the dye fixation properties of the substantially linear polyamines are maximized when the alkyleneoxy unit is absent, i.e., R' and RZ
are hydrogen. R' is also acyl having the formula:
O
-C~ Rs wherein RS is C,-C2~ linear or branched alkyl, C3-C22 linear or branched alkenyl, or mixtures thereof; preferably RS is a hydrocarbyl moiety which sufficiently provides increased fabric lubricity, more preferably C6-C,Z alkyl; hydroxy alkyl having the formula:

Most prefered linear polyamine has a backbone wherein R is 1,3-propylene and n is equal to 2, N,N'-bis(3-aminopropyl)-1,3-propylenediamine (TPTA). This preferred backbone can then be substituted or left unsubstituted in a manner which affords the formulator the maximal fabric benefit and compatibility of the low molecular weight amine with the particular embodiment. As a non-limiting example, when R' and RZ are each equal to hydrogen, dye fixative properties, in certain liquid fabric care embodiments, even in the presence of bleach, are maximal.

The procedure of Nancollas et al., described in "Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Charact., Vol 3, 77-102, (1980), is a method which is suitable for evaluating compounds for their crystal growth 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.
Without CGT
Volume of base added ) With CGI
t-lag TIIiIE
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.
Exemplary Procedure Combine in a suitable vessel, 2,IM KCl (35 mL), O.OI75M CaCI, (50mL), O.O1M
KHZPO4 (SOmL), 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-~

M. The solution is titrated to pH 7.4 with 0.05M KOH. The mixture is then treated with 5 mL's of a hydroxyapatite slurry. The hydroxyapatite 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 2.5 by the addition of sufficient 6N HCl 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. 1.5 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 50 minutes, at a concentration of 1 x IOM. 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. For example, crystal growth inhibitors have an affinity for copper ions in a solution of 0.1 ionic strength when measured at 25° C, of less than I5, preferably less than 12.

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 situ 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 Reactivity Test (CRT) Four pieces of fabric which are capable of bleeding their dye (e.g. 10 x 10 cm of lalitted cotton dyed with Direct Red 80) are selected. Two swatches are 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 i:o a "linen fabric" temperature setting. The first control swatch is also passed ten times through an ironing calender on the same temperature setting.
All four swatches ( the two control swatches and the two treated swatches, one of each TM
which has been treated by the ironing calender) are washed separately in Launder-O-Meter pots under typical conditions with a commercial detergent used at the recommended dosage for '/2 hour at 60°C, followed by a thorough rinsing of 4 times 200 ml of cola 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 beriveen two psychophysical color stimuli defined by tristimulus values, or by chromaticity 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-triazincs, vinyl sulphones, epichlorhydrine derivatives, hydroxyethylene urea derivatives.
formaldehyde condensation products, polycarboxylates, glyoxal and giutaraldehyde 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.

-O-C-R' is a fatty acyl moiety. Suitable fatty acyl moieties for use in the softener actives of the present invention are derived from sources of triglycerides including tallow, vegetable oils and/or partially hydrogenated vegetable oils including inter alia canola oil, safflower oil, peanut oil, sunflower oil, corn oil, soybean oil, tall oil, rice bran oil. Yet more preferred are the Diester Quaternary Ammonium Compounds (DEQA's) wherein the index m is equal to 2.
The formulator, depending upon the desired physical and performance properties of the final fabric softener active, can choose any of the above mentioned sources of fatty acyl moieties, or alternatively, the formulator can mix sources of triglyceride to form a "customized blend".
However, those skilled in the art of fats and oils recognize that the fatty acyl composition may vary, as in the case of vegetable oil, from crop to crop, or from variety of vegetable oil source to variety of vegetable oil source. DEQA's which are prepared using fatty acids derived from natural sources are preferred.
A preferred embodiment of the present invention provides softener actives comprising R1 units which have at least about 3%, preferably at least about 5%, more preferably at least about 10%, most preferably at least about 15% C11-C22 alkenyl, including polyalkenyl (polyunsaturated) units inter alia oleic, linoleic, linolenic.
For the purposes of the present invention the term "mixed chain fatty acyl units" is defined as "a mixture of fatty acyl units comprising alkyl and alkenyl chains having from 10 carbons to 22 carbon atoms including the carbonyl carbon atom, and in the case of alkenyl chains, from one to three double bonds, preferably all double bonds in the cis configuration".
With regard to the R1 units of the present invention, it is preferred that at least a substantial percentage of the fatty acyl groups are unsaturated, e.g., from about 25%, preferably from about 50% to about 70%, preferably to about 65%. The total level of fabric softening active containing polyunsaturated fatty acyl groups can be from about 3%, preferably from about 5%, more preferably from about 10% to about 30%, preferably to about 25%, more preferably to about 18%. As stated herein above cis and traps isomers can be used, preferably with a cisltrans ratio is of from 1:1, preferably at least 3: l, and more preferably from about 4:1 to about 50:1, more preferably about 20:1, however, the minimum being 1:1.
The level of unsaturation contained within the tallow, canola, or other fatty acyl unit chain can be measured by the Iodine Value (IV) of the corresponding fatty acid, which in the present case should preferably be in the range of from 5 to 100 with two categories of compounds being distinguished, having a IV below or above 25.

WO 00/56848 CA 02365282 2001-08-31 PCT/[JS00/08030 Indeed, for compounds having the formula:
(R)4_m N-j-(CH2)p Q-R~ X
m derived from tallow fatty acids, when the Iodine Value is from 5 to 25, preferably 15 to 20, it has been found that a cisltrans isomer weight ratio greater than about 30/70, preferably greater than about 50/50 and more preferably greater than about 70/30 provides optimal concentrability.
For compounds of this type made from tallow fatty acids having a Iodine Value of above 25, the ratio of cis to traps isomers has been found to be less critical unless very high concentrations are needed. A further preferred embodiment of the present invention comprises DEQA's wherein the average Iodine Value for R1 is approximately 45.
The R1 units suitable for use in the isotropic liquids present invention can be further characterized in that the Iodine Value (IV) of the parent fatty acid, said IV
is preferably from about 10, more preferably from about 50, most preferably from about 70, to a value of about 140, preferably to about 130, more preferably to about 115. However, formulators, depending upon which embodiment of the present invention they choose to execute, may wish to add an amount of fatty acyl units which have Iodine Values outside the range listed herein above. For example, "hardened stock" (IV less than or equal to about 10) may be combined with the source of fatty acid admixture to adjust the properties of the final softener active.
A prefered source of fatty acyl units, especially fatty acyl units having branching, for example, "Guerbet branching", methyl, ethyl, etc. units substituted along the primary alkyl chain, synthetic sources of fatty acyl units are also suitable. For example, the formulator may with to add one or more fatty acyl units having a methyl branch at a "non-naturally occuring" position, for example, at the third carbon of a C 17 chain. What is meant herein by the term "non-naturally occuring" is "acyl units whihc are not found in significant (greater than about 0.1%) quantities is common fats and oils which serve as feedstocks for the source of triglycerides described herein."
If the desired branched chain fatty acyl unit is unavailable from readily available natural feedstocks, therefore, synthetic fatty acid can be suitably admixed with other synthetic materials or with other natural triglyceride derived sources of acyl units.
The following are examples of preferred softener actives according to the present invention.
