| abstract | 1401649 Fire-proofing acrylic fibres MITSUBISHI RAYON CO Ltd 11 Oct 1972 [21 Oct 1971] 46843/72 Heading D1P Acrylic fibres are fire-proofed by treating with a hydroxylamine salt at a pH of not more than 7 to such an extent that the treated fibre has a solubility of not more than 50% in dimethylformamide at 90‹C, and heating the treated fibre in a gaseous atmosphere. The hydroxylamine salt may be lactate, tartrate or benzoate, nitrate, phosphate, acetate, formate, oxalate, succinate, fumarate, maleate, sulphate or hydrochloride. The treating solution may contain buffering agents, e.g. sodium, potassium, ammonium or zinc phthalate, phosphates, pyrophosphate, triphosphate, citrate, tartrate, oxalate or acetate. The treated fibres can be heated up to 305‹C in air, oxygenenriched air, nitrogen monoxide, nitrogen dioxide or a halogen-containing gas, and introgen or argon may also he present. The acrylic fibre may contain units of acrylonitrile, vinyl acetate, methyl acrylate, ethyl acrylate, 2-diethylamino ethyl methacrylate, methyl vinyl ether, acrylic or methacrylic acid and metal salts thereof, acryloyl or methacryloyl chloride, acrylamide, methacrylamide, itaconic acid and metal salts thereof, itaconamide, N-methyl acrylamide, N-methoxy acrylamide, N-methyl methacrylamide, vinyl chloride, vinylidene chloride, vinyl pyridene, glycidyl acrylate, glycidyl methacrylate, vinyl sulphonic acid, methallylsulphonic acid, allylloxybenzene sulphonic acid, methallyloxbenzene sulphonic acid and metal salts thereof. The fibres can be in the form of tows, filaments, silver, yarns, woven, knitted or non-woven fabrics or paper. The treated fibres may be carbonised or graphitized by heating to 300-2500‹C in an inert atmosphere. |
