Definitions

• This invention relates to improved textile finishing materials, and methods of treating yarns and fabrics therewith.
• a further object of the invention is to provide a method of finishing fabrics which involves applying the finishing agent to the warp yarns prior to weaving, whereby the weaving operation is facilitated and a suitably finished fabric is obtained without further treatment.
• the yarn or fabric is treated with an aqueous solution or dispersion of an ammonium or amine salt of copolymerized styrene maleic anhydride and a polyamine, after which the yarn or fabric is heated.
• This causes the styrene maleic anhydride copolymer to react with the polyamine, thereby insolubilizing the resin so that most of it remains on the fabric after washing and provides a substantially permanent finish.
• the polyamines which may be used for the purposes of this invention include ethylene diamine, diethylene triamine, tetraethylene pentaamine, and the like.
• Suitable ammonium or amine salts of the copolymer include the salts of ammonia, 'guanidine, alkylamines, such as methyl, butyl and amyl amine, and quaternary ammonium hydroxides, such as phenyl trimethyl ammonium hydroxide.
• the solution or bath below 110 F. to avoid appreciable reaction taking place during the impregnation ofthe" fabric.
• the bath may be kept at somewhat higher temperatures for short periods without harmful effect.
• the fabric Upon removal from the bath, the fabric is heated at an elevated temperature until it is dry. Preferably, the fabric is heated at 250 to 300 F., but satisfactory results may be obtained at temperatures as low as 200 F.
• the concentration of the styrene maleic salt in the bath and the pick-up should be adjusted to 55 deposit on the fabric from 2 to 15% by weight of the styrene maleic salt, but preferably between about 4'and 7%.
• the polyamine is ordinarily added in amounts varying between and 30% on the weight of the styrene maleic salt,
• the copolymer of styrene and maleic anhydride used in accordance with this invention is a wellestablished product which may be prepared in several ways.
• One of the well-known methods is mass polymerization, which involves heating styrene and maleic anhydride at temperatures between about and 300 F. for several hours or more. Preferably, the materials are heated cautiously, as in a water bath.
• Another method which may be used is known as the solvent process which involves reacting the styrene and maleic anhydride at slightly elevated temperatures in the presence of a solvent which is capable of dissolving both the starting materials and the finished polymer, such as acetone.
• the copolymerization may be carried out in the presence of a catalyst, such as benzoyl peroxide.
• copolymer of styrene and maleic anhydride produced by either of the above or by any other well-known method of manufacture is soluble in acetone, but insoluble in alcohol or benzene, and forms water-soluble salts of ammonia or alkali metals.
• styrenes such as methyl or butyl styrene, chlorstyrene or the like, may be used to prepare copolymers which are soluble in dilute aqueous solutions of alkali or ammonia.
• maleic anhydride partially esterifled maleic anhydride, such as the half ester of isopropyl maleate may be used.
• copolymers of styrene. and maleic anhydride which have have been copolymerized with relatively small amounts of other unsaturated compounds, such as vinyl acetate, vinyl chloride, vinyl ethyl ether, indene, vinyl methyl ketone, acrylic esters and the like.
• Example I A solution of an ammonium salt of styrene maleic anhydride resin was prepared by mixing together 600 parts of styrene maleic anhydride, prepared by copolymerizing equimolecular quantitles of styrene and maleic anhydride at about 200 F. in a water bath, 400 parts of 26% NHiOH and 9000 parts of water. The resulting mixture was then heated to 200 to 212 F. with stirring, and maintained at this temperature until a uni- Instead of styrene, substituted form, somewhat viscous transparent solution resulted. This required about one hour. After cooling thesolution to about 100 F., ethylene diamine was added to the extent of about on the weight of the styrene maleic anhydride used.
• Heavy cotton sheeting was dipped in the bath prepared as described above, after which it was passed through a padder adjusted for 100% pickup.
• the bath was maintained at about 100 1''. during the treatment of the fabric to insure uniform penetration.
• the treated sheeting was then heated for about two and a half minutes on a tenter frame using hot air at 300 F.. at which time it was substantially dry.
• the dry sheeting was washed for one hour at the boil in a running suds, and was found to retain 82% of the deposited resin.
• Example II A solution of an ammonium salt of styrene maleic anhydride resin, containing 10% ethylene diamine was prepared as described in Example 1.
• the resulting solution was then poured into the size box of a slasher, after which. a warp of 18/single cotton yarn was passed through the solution and dried on dry cans in the usual manner, using 12 pounds of steam. The treated yarn was then rolled up on a beam and woven. Excellent weaving was obtained and the resulting fabric possessed a desirably stiffened finish which retained its stiffened character even after washing. Moreover, the fabric had an unusually smooth feel and did not dust out.
• Emmpie III Heavy cotton sheeting was dipped in the bath prepared as described above, after which it was passed through a padder adjusted for 100% pickup.
• the bath was maintained at about 100 F. during the treatment of the fabric to insure uniform penetration.
• the treated sheeting was then heated for about two and a half minutes on a tenter frame using hot air at 300 F., at the end of which time it was substantially dry.
• the dry sheeting was washed for one hour at the boil in a running suds, and was found to retain 85% of the deposited resin.
• Example IV A solution of an ammonium salt of styrene maleic anhydride resin was prepared as described in Example I, and diluted with an equal amount of water. To this was then added diethylene triamine in an amount sufficient to provide about 10% on the weight of the styrene maleic anhydride used. Spun viscose rayon was dipped in the resulting bath, after which it was passed through a padder adjusted for 100% pickup. The bath was maintained at about 100 F. during the treatment of the fabric to insure uniform penetration. The treated rayon was then heated for about two and a half minutes on dry cans maintained at about 240 1"., at the end of which time it was substantially dry. The resulting fabric was smooth and full and somewhat stiffened, and retained these characteristics after several washings.
• Example V I full and somewhat stiflened and retained these characteristics after washing.
• the reaction between the polymerized styrene maleic anhydride salt and the polyamine involves or consists of a cross linking between the polymer and the polyamine. It should be understood, however, that the invention is not predicated on this or any other similar theory, and regardless of the type of reaction which takes place the polymeric resin salt becomes insolubilized on the yarn or fabr'ic with the formation of a relatively'permanent size or finish. It should also be understood that the aqueous solutions referred to in the appended claims are intended to include aqueous dispersions, as it is possible that the ammonium or amine salts in the solution are actually present in the form of a colloidal dispersion.
