Abstract: 1,056,283. Textile-treating compositions; aminoplast compositions. BADISCHE ANILIN- & SODA-FABRIK A.G. Nov. 5, 1963 [Nov. 10, 1962], No. 43585/63. Headings C3P and C3R. [Also in Division D1] A composition suitable for treating cellulosic fabrics comprises a compound which improves the crease resistance of the fabric and a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0À5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N- methylolmethacrylamide or an ether derivative thereof and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5 - triacyl - hexahydrotriazine - (1,3,5) allyl acrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinylpyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diureine, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetal, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The composition may be in the form of an aqueous solution or dispersion containing 30-150 g./l. of the crease-resisting agent and 5-100 g./l. of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants, colouring pigments and an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, monoammonium phosphate, ammonium nitrate and ammonium acetate.

Abstract: Textile fabrics which contain at least 25% by weight of cellulosic fibres, e.g. cotton and viscose rayon, are treated with an aqueous liquor which contains (a) a reaction product of an aminoplast-forming substance with formaldehyde which contains in the molecule at least two nitrogen atoms and, connected to nitrogen, at least two methylol groups or etherified methylol group and (b) a copolymer from 1-25% by weight of a compound of the general formula in which R1 stands for -H or -CH3, and 99-75% by weight of an ester formed from an acid in which R2 stands for -H or -CH3 and a monohydric saturated aliphatic alcohol with 1-5 carbon atoms, and are then subjected, conveniently after drying, to a mechanical treatment, e.g. embossing, pleating or schreinering, at a temperature of 140 DEG -210 DEG C. and heated to above 100 DEG C. up to 200 DEG C. The fabrics may be dried before the mechanical treatment at 70 DEG -150 DEG C. until they have a residual moisture content of 6-14% by weight. In addition to the acrylic and methacrylic acid esters, other copolymerisable compounds, e.g. vinyl chloride, vinyl esters and ethers made from acids and alcohols having 1-5 carbon atoms, butadiene, vinyl lactams, such as pyrrolidone or caprolactam, styrene and substituted styrene, may be used for the preparation of the copolymer. Specified aminoplast precondensates are tetramethylol glyoxal diureine, dimethylol urea dimethyl ether, dimethylol ethylene urea, dimethylol N-alkyl triazinones, dimethylol urea, dimethylol glyoxal mono ureine, dimethylol butane-diol diurethane and di-, tri- and hexamethylol melamines. The composition may also contain a dispersing agent, e.g. a reaction product of iso-octylphenol or a fatty acid monoethanol amide with ethylene oxide, and as hardening catalyst ammonium nitrate, chloride or sulphate, mono- or di-ammonium phosphate, zinc nitrate or magnesium chloride. The mechanical treatment may be carried out immediately following drying or impregnation or the impregnated fabric may be allowed to lie for hours or days and then subjected to the mechanical treatment.
