Description

FABRIC MAINTENANCE COMPOSITIONS COMPRISING CERTAIN CATIONICALLY CHARGED FABRIC MAINTENANCE POLYMERS

FIELD OF THE INVENTION The present invention relates to fabπc dye maintenance compositions which compπse one or more dye maintenance compounds which can be o gomers, polymers, co-polymers, and the like which compπse one or more monomers which results in the final dye maintenance compound having a net positive charge. Compositions compπsmg the dye maintenance polymers of this invention impart appearance and mtegπty benefits to fabπcs 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 laundeπng fabπcs and textiles, such as articles of worn clothing and apparel, will inevitably adversely affect the appearance and mtegπty of the fabπc and textile items so used and laundered. Fabπcs and textiles simply wear out over time and with use. Laundeπng of fabπcs and textiles is necessary to remove soils and stains which accumulate therein and thereon duπng ordinary use. However, the laundeπng operation itself, over many cycles, can accentuate and contπbute to the deteπoration of the mtegnty and the appearance of such fabπcs and textiles

Deteπoration of fabπc mtegnty and appearance can manifest itself in several ways Short fibers are dislodged from woven and knit fabπc/textile structures by the mechanical action of laundeπng. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabπcs and diminish the appearance of newness of the fabπc. Further, repeated laundeπng of fabπcs and textiles, especially with bleach-contammg laundry products, can remove dye from fabπcs 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 mateπals which could be added to fabπc treatment products, specifically to πnse added fabπc conditioners, pre-wash spray on compositions, pre-soak compositions as well as after wash or between wash malodor control or fabπc re-freshenmg compositions, mateπals which would associate themselves with the fibers of the fabπcs and textiles thereby reducing, abating, or minimizing the tendency of the fabπc/textiles to deteπorate in appearance. Any such fabric treatment/fabric maintenance composition additive mateπal should, of course, be able to benefit fabπc appearance and mtegπty without unduly interfeπng 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 fabπc treatment and fabπc enhancement compositions which perform in this desired manner

SUMMARY OF THE INVENTION The present invention meets the aforementioned need in that it has been surpnsmgly discovered that fabπc 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 aha, due to mechanical wear and abrasion. In addition, fabπc 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, πnse additive, etc. The compositions of the present invention can be added is any manner, inter aha, as part of a formulation or as a separate composition

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

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to attenuation and/or abatement of fabπc 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 polyamme, fabric softness agent (crystal growth inhibitor) and dye fixing agent to provide protection to fabπc from appearance loss which is pπmarily 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 polyamme, fabric softness agent (quaternary ammonium fabnc softener active), dye fixing agent, and one further enhancement agent, inter aha, 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 fabπc enhancement polyamme, fabric softness agent (crystal growth inhibitor) and quaternary ammonium fabπc softness agent, and dye fixing agent. The normal abrasive destruction of the fabπc surface removes the surface layers of fabπc which are dyed. Especially in the case of cotton fabnc, below this layer of dyed fabnc is the less dyed, then non-dyed fabπc. As wears a "washed looked" develops which is due to the abrasive destruction of fabric and the subsequent loss of the weakened fabnc fiber m the laundry cycle.

It has been surpnsmgly discovered that the combination of elements which compπse the compositions of the present invention modify the surface of fabric, especially cellulosic fabπc and ameliorate many of the conditions which enhance fabric fiber surface wear and subsequent loss. The compositions of the present invention also soften the fabnc surface making the fibers less abrasive and thereby reducing the level of friction between the fabnc and surfaces in which the garment comes into contact. This change in surface condition can nullify many of the conditions which contnbute to fabric damage and hence attenuate, and in some cases, abate fabnc damage and therefore the concomitant loss of color.

The compositions of the present invention can be used for a stand alone treatment of fabnc wherein the compositions are added as ingredients to a compatible fully formulated πnsed additive, laundry additive or pre-soak all of which are used together with fabπc 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 fabnc.

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 fabπc 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 fabπc during laundenng. 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 "Crystal Growth Inhibition Test" is used to determine the suitability of a mateπal for use as a crystal growth inhibitor.

Crystal Growth Inhibition Test (CGIT)

The suitability of a mateπal 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., descnbed m "Calcium Phosphate Nucleation and Growth m 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 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.

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, 2.1M KC1 (35 mL), 0.0175M CaCl₂ (50mL), 0.01M KH₂P0₄ (50mL), 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 10⁶ 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 HC1 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 πnsmg procedure is repeated six more time after which the pH of the solution is adjusted to neutrality using 2N HC1. 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 lO^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. For example, crystal growth inhibitors have an affinity for copper ions m a solution of 0.1 ionic strength when measured at 25° C, of less than 15, preferably less than 12.

The cellulose reactive dye fixatives may be suitably combined with one or more dye fixatives described herein above m order to comprise a "dye fixative system"

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 knitted 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 dned. One of the treated swatches which has been thoroughly dned, is passed ten times through an ironing calender which is adjusted to a "lmen fabπc" 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 which has been treated by the ironing calender) are washed separately m Launder-O-Meter pots under typical conditions with a commercial detergent used at the recommended dosage for ^lΛ hour at 60°C, followed by a thorough nnsmg of 4 times 200 ml of cold water and subsequently line dned.

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 m ASTM D2244. In general, DE values relate to the magnitude and direction of the difference between two psychophysical color stimuli defined by tnstimulus values, or by chromaticity coordinates and luminance factor, as computed by means of a specified set of color-difference equations defined the CIE 1976 CIELAB opponent-color space, the Hunter opponent-color space, the Fπele-Mac Adam-Chickermg 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-tπazmes, vmyl sulphones, epichlorhydrme 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 electrophihc groups and their corresponding cellulose affinity. Preferred hydroxyethylene urea denvatives include dimethyloldihydroxyethylene, urea, and dimethyl urea glyoxal. Preferred formaldehyde condensation products include the condensation products denved 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 Clanant, Zetex E ex Zeneca and Levogen BF ex Bayer.

Suitable fatty acyl moieties for use in the softener actives of the present invention are denved from sources of tπglycendes including tallow, vegetable oils and/or partially hydrogenated vegetable oils including inter aha canola oil, safflower oil, peanut oil, sunflower oil, com 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 fabnc softener active, can choose any of the above mentioned sources of fatty acyl moieties, or alternatively, the formulator can mix sources of tπglycende to form a "customized blend". However, those skilled m 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 vaπety of vegetable oil source to vanety of vegetable oil source. DEQA's which are prepared using fatty acids denved from natural sources are preferred.

A preferred embodiment of the present invention provides softener actives compnsmg R! units which have at least about 3%, preferably at least about 5%>, more preferably at least about 10%), most preferably at least about 15%> C\ 1-C22 alkenyl, including polyalkenyl (polyunsaturated) units inter aha oleic, hnoleic, lmolenic

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 R* 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 trans isomers can be used, preferably with a cisltrans ratio is of from 1:1, preferably at least 3: 1, 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 withm 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 categones of compounds being distinguished, having a IV below or above 25 Indeed, for compounds having the formula:

(RV N- -(CH -Q-R¹ X ^'

4-m m

denved from tallow fatty acids, when the Iodme 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 Iodme Value of above 25, the ratio of cis to trans isomers has been found to be less cntical unless very high concentrations are needed. A further preferred embodiment of the present invention compπses DEQA's wherein the average Iodme Value for R* is approximately 45.

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 Iodme 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 occurmg" position, for example, at the third carbon of a C \ η chain What is meant herein by the term "non-naturally occunng" 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 tnglycerides 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 tπglyceπde derived sources of acyl units.
