Abstract

Polyvinyl alcohol fibres are spun from aqueous solutions comprising (A) polyvinyl alcohol containing more than 98 mole per cent of vinyl alcohol units, (B) a water-soluble polyvinyl alcohol-urea derivative containing at least 80 mole per cent, and preferably 80 to 99 mole per cent vinyl alcohol units, the urea-derived nitrogen content based on B being 0,1 to 6,0% by weight, and based on A and B being 0,05 to 4,5% by weight, and optionally (C) a water-soluble saccharide or water-soluble derivative thereof. B may be prepared by reacting urea with polyvinyl alcohol, completely or partially saponified polyvinyl acetate or ethylene-vinyl acetate copolymer, or partially acetalized polyvinyl alcohol, either in the fused state or in the presence of a solvent such as dimethyl formamide. Specified saccharides and derivatives are glucose, sucrose, starch, dextrin, gum arabic, gum tragacanth, methyl glucose, acetyl glycose, methyl sucrose, methyl starch, ethyl starch, carboxymethyl starch, hydroxyethyl starch, cyanoethyl starch, carboxymethyl cellulose, carboxyethyl cellulose and hydroxyethyl cellulose. Fibres may be dry spun or wet spun into aqueous solutions of salts, such as sodium sulphate and ammonium sulphate. The fibres may be subjected to physical and chemical treatments such as cold-drawing, hot-drawing, heat treatment at constant length, heat-shrinkage, chromination or titanation, and may be acetalized by reacting with an aldehyde containing 1 to 12 carbon atoms, e.g. formaldehyde, acetaldehyde and benzaldehyde, in the presence of mineral acids such as sulphuric, hydrochloric, phosphoric and periodic acid, salt thereof, organic solvents and surface active agents. Examples describe the spinning of fibres from spinning solutions comprising polyvinyl alcohol and (I, III and IV) saponified polyvinyl acetate-urea reaction products, (V) polyvinyl alcohol-urea reaction product and (VI) ethylene-vinyl alcohol copolymer-urea reaction product; polyvinyl alcohol and saponified polyvinyl acetate-urea reaction products together with (VII and XII) starch, (IX) sodium carboxymethyl cellulose and (XI) glucose; and polyvinyl alcohol and polyvinyl alcohol-urea reaction products together with (X) gum arabic and (XIII) sodium carboxymethyl cellulose; and the formalization or benzalization of I, VI and XI with aqueous solutions containing formaldehyde or benzaldehyde, sulphuric acid and methanol; the treatment of V and XI with aqueous solutions comprising sodium periodate, sulphuric acid and sodium sulphate; the formalization of VII with aqueous solutions comprising formaldehyde, sulphuric acid and sodium sulphate; the benzalization of VII with aqueous compositions comprising benzaldehyde, sulphuric acid and methanol; the formalization of IX with aqueous solutions comprising formaldehyde and sulphuric acid and the mixed acetalization of XIII with aqueous solutions comprising formaldehyde, b -cyclohexylamino butyraldehyde, sulphuric acid and sodium sulphate.
