    Abstract: The pile of pile fabrics, e.g. carpets, velvet, plush, cord and velveteen, derived for example from natural or regenerated cellulose fibres, wool, silk, cellulose ester, polyamide, polyester and acrylonitrile polymer fibres, is secured by treating the reverse side of the fabrics with dispersions of copolymers derived from 1-25% by weight of an N-methylolamide of an acrylic acid that may be etherified and 99-75% by weight of one or more other polymerizable compounds and subjecting the fabrics to a heat treatment at a temperature above 100 DEG C. In addition to the N-methylolamide of an acrylic acid or ether thereof the copolymer may also comprise other unsaturated carboxylic acid amides, derivatives of these carboxylic amides which are mono substituted at the nitrogen atom and the methylol compounds of these amides, esters, nitriles and N-disubstituted amides of unsaturated carboxylic acids, vinyl esters, halides, cyanides, ethers, ketones and aromatics, vinylidene halides and cyanides, C-vinyl pyridine, N-vinyl compounds, e.g. N-vinyl imidazole, N-vinyl pyrrolidone, N-vinyl caprolactam and N-vinyl pyridine, unsaturated aldehydes and esters of unsaturated alcohols, e.g. allyl and methallyl alcohols. The fabrics may be treated on the reverse side with aqueous dispersions of the copolymers having a concentration of 3-50% with reference to the weight of the liquor by coating or padding, dried at temperatures up to 100 DEG C. and then heat treated at temperatures above 100 DEG C. The dispersions may also contain thickeners, e.g. starch, cellulose and starch ethers, polyacrylic acids and their salts and salts of copolymers derived from acrylonitrile and acrylic acid, resin forming substances, e.g. tetramethylol acetone, dimethylol acetal, dimethylol urea, trimethylol melamine, dimethylol ethylene urea, dimethylol glyoxal monoureine, dimethylol butane diol diurethane, dimethylol adipamide, dimethylol propylene urea, dimethylol alkyl triazones and ethers thereof and polyfunctional epoxy compounds such as glycol and diglycol diglycidyl ethers, in combination with hardening catalysts, organic and inorganic fillers and pigments, polyacrylamides, polyvinyl ethers, polyvinyl esters, polyvinyl alcohol, clay, kaolin, china clay, barium sulphate, calcium carbonate, titanium dioxide, zinc oxide, iron oxide, chromium oxide and substative dyes. The treatment may be carried out in conjunction with a padding impregnation with a water repellant comprising a metal salt/paraffin emulsion or silicone.

    Abstract: 880,993. Agglutinated fibrous fabrics; impregnated paper &c. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 30, 1959 [Nov. 5, 1958], No. 36863/59. Classes 96 and 140. A process for the production of a bonded fibre fleece comprises employing as a binder a copolymer derived from 1 to 20% by weight of an alpha-beta unsaturated carboxylic acid amide substituted on nitrogen by at least one methylol group, and 80 to 99% by weight of at least one other polymerizable compound, the fleece containing the binder being heated for a short time, e.g. 3 to 10 minutes, at over 60‹ C. Fibrous materials mentioned are cotton, rayon, cellulose acetate, wool, sisal, polyamides, polyvinyl chloride, polyacrylonitrile, polyterephthalic acid esters, rock wool, slag wool, glass fibres and asbestos fibres, and the polymerizable compound may be an ethylenically unsaturated monomer, e.g. acrylic and methacrylic acid esters, e.g. butyl acrylate, vinyl esters and ethers, styrene, acrylonitrile, and olefines, or mixtures thereof. The methylol compound may be N-methylolamide of acrylic, methacrylic or maleic acid. The binder may be applied as an aqueous emulsion or dispersion, or dissolved in an organic solvent, or strewn in the solid state on the fleece. If the binder is in liquid form, the heating operation may be in two stages, the first at 60‹ C. to 100‹ C., the second at 80‹ C. to 160‹ C. The fleece, prior to impregnating, may be formed by carding, and may be laminated so that the fibres in successive layers lie at an angle to each other, or a random arrangement of fibres may be employed, e.g. by suspending in water which is sucked off on a sieve. Impregnation may be carried out by spraying or soaking, and the liquid may be supplied between two fleeces as they are passed between two rollers under light pressure the fleeces having undergone a preliminary consolidation prior to impregnation. Compounds may be added to the binder to accelerate the reaction, e.g. phosphoric acid, paratoluenesulphonic acid, acetic acid, AlCl 3 , NH 4 NO 3 , NH 4 Cl, and ammonium oxalate, and soluble dyestuffs, colour pigments, plasticizers, stabilizers and optical brightening agents may be added to the binder. Four examples are described in detail and one describes the passing of the impregnated fleece through a bath consisting of melamine-urea precondensate and ammonium oxalate.
