    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.
