[ ABSTRACT Aqueous blends of (l) a waterdissipatable linear copolyester; (2) an amino resin crosslinking agent; and

10 Claims, No Drawings FINISHING AGENTS FOR TEXTILES This invention relates to compositions useful as finishing agents for textile articles. More specifically, this invention relates to compositions useful as finishing agents for textile articles containing polyester fibers. The compositions of this invention are useful for modifying the hand or handle of polyester fabrics as well as reducing the tendency of knitted and woven fabrics constructed from texturized polyester yarns to snag or pick on sharp or abrasive objects during wear.

Knitted and woven fabrics constructed from texturized polyester yarns or yarns containing polyester fibers have the unfortunate tendency to snag or pick during normal wear. Snags detract from the appearance of garments and shorten acceptable wear-life. The hand or handle of polyester-containing fabrics, particularly those containing only texturized polyester yarns, is also difficult to modify permanently with conventional finishing agents in that many have a tendency to lose their finish during dry cleaning and washing procedures.

lt is an object of this invention to provide compositions useful as finishing agents that impart a durable handle to textile articles containing polyester fibers and that reduce the tendency of fabrics constructed from textured polyester yarns to snag 'or pick on sharp or abrasive objects in wear. It is a further object of this invention to provide crosslinkable, aqueous blends when applied to fabrics which provide excellent adhesion to polyester and many other fibrous substrates, good wash resistance, excellent dry cleaning resistance, and excellent handle. It is a further object of this invention to provide novel compositions which have applications in the areas of spray binding for staple fibers as a nonwoven fabric binder, a knit fabric hand builder, an antipick resin, a flocking adhesive and a fabric finish.

Water-dissipatable copolyesters derived from at least one dicarboxylic acid component, at least one diol component, at least 20 mole percent of said diol being a poly(ethylene)glycol, and a difunctional monomer containing a -SO M group wherein M is a monovalent alkali metal are disclosed in US. Pat. Nos. 3,734,874, 3,546,008 and 3,779,993. Furthermore, aqueous dispersions of coating compositions consisting of the above type copolyesters dispersed together with a melamine-formaldehyde resin have been sold under the trade name of WDX-743, WDX-744 and Eastman Binder DFB, products of Eastman Kodak Company. These aqueous coating compositions, however, provide coatings which produce a very stiff, unpleasant hand or feeling to polyester fabrics. The compositions of this invention improve over the prior art compositions in that they impart a durable handle to textile articles and have advantageous picking and snagging properties.

In one aspect of this invention there is provided textile finishing agents which are prepared from aqueous blends of l a water dissipatable linear copolyester of the type disclosed in US. Pat. No. 3,734,874 and US Pat. No. 3,546,008, (2) an amino crosslinking resin, and (3) a polyoxyethylene containing glycol. An acid or latent acid catalyst is used to effect a thermallyinduced crosslinking reaction which, when carried out on the surface of textile fibers, leaves a water-insoluble film having good adhesion to textile fibers. The compositions thus formed, which partially or wholly covers the fiber surfaces and in some instances forms interfiber bonds, imparts an illusion of added weight and bulk to the fabric and reduces the tendency of the fabric to snag or pick. The handle of the finished fabric may be controlled by judicious selection of the ratio of the three components in finishing agent formulation as hereinafter described.

The compositions of this invention can be more specifically defined as an aqueous blend of the following components:

I. from about 50 to about 85 (preferably about to about parts by weight of a linear, waterdissipatable polyester derived from components (A), (B) and (C) as follows:

A. at least one dicarboxylic acid,

B. at least one diol, at least 20 mole percent of said diol component being a poly(ethylene)glycol having the formula H-OCH CH ),,OH wherein n is an integer of from 2 to about 14, and

C. at least one difunctional dicarboxylic acid sulfomonomer containing a SO M group attached to an aromatic nucleus, wherein M is Na", Li, K, or a combination thereof, said sulfomonomer component constituting at least about 8 mole percent to about 45 mole percent of the sum of the moles of said components (A) and (C);

2. from about l5 to about 50 (preferably about 20 to about 30) parts by weight of at least one waterdissipatable amino resin having atleast two reactive groups, said resin being selected from the group consisting of melamine-formaldehyde condensates, methylated melamine-formaldehyde condensates, urea-formaldehyde condensates, methylated urea-formaldehyde condensates, guanamineformaldehyde condensates and methylated guanamine-formaldehyde condensates; and

3. from about 10 to about (preferably about 10 to about 60) parts by weight of a water-dissipatable nonionic linear poly(oxyethylene) containing glycol having the formula (I) HO-(-CH CH O)-,, ,H wherein m is an integer from about 4 to about I50,

wherein x, y, and z are integers, the sum of which results in a glycol having a molecular weight from about 1,000 to about 14,000, and the ratio of x z to y is such that the hydrophile/lipophile balance is from about 4.5 to about 30.5.

ln one preferred embodiment of this invention the above aqueous blends contain about 0.5 to about 50 percent by weight of combined solids supplied by components l), 2) and 3).

The dicarboxylic acid component (A) from which the linear water-dissipatable polyester component of this invention is prepared can be any aliphatic, cycloaliphatic, or aromatic acid. Examples of such dicarboxylic acids include oxalic; malonic; dimethylmalonic; succinic; glutaric; adipic; trimethyladipic; pimelic; 2,2-dimethylgultaric; azelaic; sebacic; fumaric; maleic; itaconic; l,3-cyclopentanedicarboxylic; 1,2- cyclohexanedicarboxylic, 1,3- cyclohexanedicarboxylic; l,4-

cyclohexanedicarboxylic; phthalic; terephthalic; isophthalic; 2,5-norbornanedicarboxylic; l,4-naphthalic; diphenic; 4,4'-oxydibenzoic; diglycolic; thiodipropiglycol;

onic; 4,4'-sulfonyldibenzoic; and 2,5-

naphthalenedicarboxylic acids. In a preferred embodiment of this invention isophthalic acid is the dicarboxylic acid utilized. If terephthalic acid is used as the dicarboxylic acid component of the polyester, especially good results are achieved when at least five mole percent of one of the other acids listed above is used.

It should be understood that the use of the corresponding acid anhydrides, esters, and acid chlorides of these acids is included in the term dicarboxylic acid." The esters are preferred, examples of which include dimethyl l,4-cyclohexanedicarboxylate; dimethyl 2,6- naphthalenedicarboxylate; dibutyl 4,4-sulfonyldibenzoate; dimethyl isophthalate; dimethyl terephthalate; and diphenyl terephthalate. Copolyesters may'be prepared from two or more of the above dicarboxylic acids or derivatives thereof.

At least about mole percent of the diol component (B) used in preparing the water-dissipatable polyester component of the invention is a poly(ethylene)glycol having the formula H+OCH CH ),,OH wherein n is an integer of from two to about ten. Examples of suitable poly(ethylene)-glycols include diethylene, triethylene, tetraethylene, pentaethylene, hexaethylene, heptaethylene, octaethylene, nonaethylene, and decaethylene glycols, and mixtures thereof. Preferably the poly(ethylene)glycol employed in the polyester of the present invention is diethylene glycol, triethylene glycol, or mixtures thereof. The remaining portion of the diol component is at least one aliphatic, cycloaliphatic, or aromatic diol. Examples of these diols include ethylene propylene glycol; 1,3-propanediol; 2,4- dimethyl-Z-ethylhexanel ,3-diol; 2,2-dimethyl-l ,3- propanediol, 2-ethyl-2-butyl-l,3-propanediol; 2-ethyl- 2-isobutyl-l ,3-propanediol, l,3-butanediol; 1,4- butanediol; l,5-pentanediol; 1,6-hexanediol; 2,2,4- trimethyl-l ,6-hexanediol; l,2 cyclohexanedimethanol; 2,2,4,4-tetramethyl-l ,3-cyclobutanediol; and pxylylenediol. Copolymers may be prepared from two or more of the above diols.

The third component (C) used to prepare the waterdissipatable polyester is a difunctional monomer containing a SO M group attached to an aromatic nucleus, wherein M is hydrogen or a metal ion. This difunctional monomer component may be either a dicarboxylic acid (or derivative thereof) containing a SO M group or a diol containing a -SO M group.

The metal ion of a sulfonate salt group may be Nafi,

Li or K".

Other effective difunctional monomers containing a SO M group attached to an aromatic nucleus include metal salts of aromatic sulfonic acids (or esters thereof). These monomers have the general formula ROOC o -O-Y-SO3 M ROOC/ o SO M group attached to an aromatic nucleus include metal salts of sulfodiphenyl ether dicarboxylic acids (or esters thereof). These monomers have the general formula wherein R is hydrogen, an alkyl group of one to eight carbon atoms, or phenyl, M is Na Li, or K*, and a is l, 2, or 3. Examples of preferred monomers here are dimethyl 5-[4-(sodiosulfo)phenoxy]isophthalate, dimethyl 5-[4-(sodiosulfo)phenoxy]terephthalate, and 5-[4-(sodiosulfo)phenoxy]isophthalic acid.

The water-dissipatable polyester should contain at least about eight mole percent of the monomer based on total acid content, with about 10 mole percent giving particularly advantageous results. Greater dissipatability is achieved when the difunctional monomer constitutes from about 10 mole percent to about 45 mole percent of the total content of acid of the polyester.

To obtain the polyester component of this invention, the difunctional monomer containing the SO M group may be added directly to the esterification reaction mixture from which the polyester will be made. Thus, these monomers can be used as a component in the original polyester reaction mixture. Other various processes which may be employed in preparing these polyesters are well known in the art and are illustrated in such patents as US. Pat. Nos. 2,465,319; 3,018,272; 2,901,466; and 3,075,952. These patents illustrate ester interchange and polymerization processes.

Whenever the term inherent viscosity (I.V.) is used in this description, it will be understood to refer to viscosity determinations made at 25C. using 0.5 gram of polymer per ml. of a solvent composed of 60% phenol and 40% tetrachloroethane as parts by weight. In addition, whenever the terms dissipatable, dissipated or dissipate," are used in this descrip tion, it will be understood to refer to the action of water or aqueous solutions on the components of the blends of this invention. The terms are specifically intended to cover those situations wherein the solution dissolves and/or disperses these blends. Furthermore, whenever the word water is used in this description, it includes not only aqueous solutions but also hot aqueous solutions.

In an especially preferred embodiment of this invention the water-dissipatable polyester component is derived from 90 mole percent isophthalic acid, mole percent of 5-sodiosulfoisophthalic acid, and 100 mole percent of diethylene glycol and having an inherent viscosity (l.V.) of at least 0.30 as measured at 25 using 0.50 gram of polymer per 100 ml. of a solvent com posed of 60 percent phenol and 40 percent tetrachloroethane. The copolyester useful in this invention may be terminated with either hydroxy or carboxy end-groups. In addition, the end-group functionality of the copolyester, and therefore its crosslinkability, may be increased by reaction of the high molecular weight linear polyester with trior tetrafunctional hydroxy or carboxy compounds such as trimethylolpropane, pentaerythritol, or trimellitic anhydride in a manner known in the art.

Examples of the water-dispersible amino resins useful in this invention include the melamine-formaldehyde condensates, the methylated (wholly or partially) melamine-formaldehyde condensates, the ureaformaldehyde condensates, methylated (wholly or partially) urea-formaldehyde condensates, the methylated (wholly or partially) guanamine-formaldehyde condensates, and the like. These amino resins are known in the art and can be prepared by known means or obtained commercially. The properties of these resins, as well as some of their uses in textiles applications, are set forth in Mark, Wooding, and Atlas, Chemical Aftertrealment of Textiles, John Wiley & Sons, Inc. (1971), pages 267-355. Preferred amino resins useful in this invention are hexamethoxymethyl melamine (Cymel 300, a registered trademark of American Cyanamid Company), partially methylated melamine formaldehyde adduct sold also under various trade names (for example, Aerotex M-3, a registered trademark of American Cyanamid Company), and various urea-formaldehyde condensates such as Aerotex Resin 802, a registered trademark of American Cyanamid Company.

Examples of poly(oxyethylene) containing glycols useful in this invention are those which have an average molecular weight of from 200 to about 7,000, the only requirement being that the poly(oxyethylene)-glycols be dispersible in water. Especially preferred poly(oxyethylene)-glycols useful in this invention are those having an average molecular weight of from about 1000 to about 6000 (eg., having the formula HO(CH CH O),,,H wherein n is an integer of from about to about 130), sold under the trade name Carbowax, a registered trademark of Union Carbide Corporation. Examples of the specific Carbowaxes useful in this invention are Carbowax 200, Carbowax 4000, and Carbowax 1000, Carbowax 4000 being especially preferred. Also useful as the poly(oxyethylene)glycol component of this invention are the water-dispersible ethylene oxidepropylene oxide block copolymer glycols which are also sold commercially under the trade name of Pluronics, a registered trademark of Wyandotte Chemicals Corporation. These glycols are the condensates of ethylene oxide with hydrophobic bases formed by condensing propylene oxide with propylene glycol and have the general formula H+ocH,CHrmocucHm vocn cumon where .r, y, and z are integers, the sum of which results in molecular weights ranging from about 1,000 to 14,000, preferably 3,000 to 10,000. The ratio ofx z/y is such that the HLB (hydrophile/lipophile balance) is from about 4.5 to about 30.5, preferably 6.6 to 24.5. [The HLB of a nonionic surfactant is defined as the approximate weight percent of ethylene oxide in the surfactant divided by 5. See W. C. Griffin, J. Soc. Cosmetic Chemists, l, 311 (1949).]

Examples of useful Pluronics are Pluronic F38, L35 and P65.

The ratio of poly(oxyethylene) containing glycol to combined parts of copolyester and amino resin used in the dispersions of this invention determines the softness of the cured film and therefore the softness of the finished textile article. If no poly(oxyethylene)glycol is used, the finished article tends to be rather stiff and boardy. Softness increases with increasing poly(oxyethylene)glycol content. Surprisingly, it has been found that the articles coated with the compositions of this invention show better softness or handle properties than the prior art compounds. In a preferred embodiment of the invention 10 to 60 parts by weight of poly (oxyethylene)glycol per parts of copolyester- /amino resin is used to produce commercially attractive hands of increasing softness.

The optimum ratio of copolyester to amino resin depends upon several factors, including amino resin functionality and reactivity, copolyester end-group concentration and reactivity, and molecular weight and concentration of poly(oxyethylene)glycol. The copolyester/amino resin ratios found useful in practice of the invention range from about 1:1 to 6:1, the preferred ratio being about 3:] copolyester/amino resin.

The above components 1), 2) and 3) are, for convenience in commercial handling, dispersed in enough water to bring the total solids content to approximately 30 percent. This concentration can then be readily diluted to the desired level for application to textile substrates when ready for use. It is desirable but not essential to include 1 to 10 parts (4 to 5 parts preferred) of a poly(oxyethylated) alkyl phenol to the 30 percent solid dispersion. This type of nonionic surfactant improves the storage life and electrolyte stability of the formulation and serves as a wetting agent for the substrate. Poly(oxyethylated) alkyl phenols are sold under various trade names, such as Triton, a registered trademark of Rohm & Haas Company, and Igepal, a registered trademark of CAP Corporation.

To apply a finish of the type disclosed in this invention to a textile substrate, a pad bath containing the desired component is prepared either by direct addition of the individual components to water or by dilution of a high solids (30 percent, for example) dispersion. The solids content of the pad bath is adjusted so as to obtain about 0.5 to 5 percent (1 to 3 percent preferred) addon of finish on the fabric when dried. in order to accelerate the curing or crosslinking reaction which insolubilizes the finish on the fabric, it is necessary to include an acid or a latent acid catalyst in the pad bath. Generally, from 0.5 to 3 percent (based on weight of solids in the pad bath) of catalyst is sufficient to effect a cure under typical textile processing conditions. The optimum catalyst concentration depends upon the catalyst used, the nature of the amino resin, and the time and temperature of curing. Examples of such suitable catalysts which may be used to promote the reaction of the amino resin with the hydroxy or carboxy groups available in the dispersion are well known in the art and include p-toluenesulfonic acid, citric acid, glycolic acid, oxalic acid, amine hydrochloride, zinc fluoborates, and

solids). To 500 g. of the diluted formulation is added 0.45 g. of citric acid (3% catalyst based on weight of bath solids). A 100% textured polyester (1-50 denier) double-knit fabric (8 oz./sq. yd., Ponti de Roma style) magnesium chloride. Citric acid and p-tolueriesulfonic is padded with the above formulation, dried at 220F. acid are preferred. Further examples of'these useful for minutes and cured at 340F. for 90 seconds. The catalysts are described in Mark, Wooding, and Atlas, dry weight increase of the fabric is 2.1%. In comparison Chemical Aftertreatment ofTextiles, John Wiley & Sons with the original, untreated fabric (heated in the same 1971 pages 332334.
