Abstract

A composition for sizing staple yarns consists of, or contains, a polymer consisting of copolymerized units of (a) acrylonitrile, and (b) acrylic acid and its sodium or ammonium salt in the molar ratio of (a) : (b) of 1 : 1.5 to 1 : 7 and which, as determined in a 10% by weight aqueous solution at 20 DEG C. has a viscosity of 20 to 2000 c.p. and a pH value of 2.5 to 6.5, the said polymer containing from 0 to 20% by weight of copolymerized units of other monomers, said monomers being soluble in water at 20 DEG C. in an amount of at least 2% by weight. The other monomers employed are e.g. acrylamide, methacrylamide, methyl, acrylate, methacrylic acid or its alkali metal or ammonium salts, maleic acid or its salts or semi-esters, methacrylonitrile and vinyl pyrrolidone. The copolymers are prepared in aqueous solution by copolymerization of acrylonitrile and acrylic acid followed by partial neutralization of the copolymer with ammonium or sodium hydroxide, or by copolymerization of acrylonitrile, acrylic acid and sodium or ammonium acrylate. The aqueous solutions produced are used, after the addition, if desired, of conventional sizing agents such as the starch ether employed in Example 7, for the sizing of cellulosic and/or acrylic fibres (see Division D1).ALSO:A process for sizing staple yarns consisting of cellulosic fibres and/or acrylic fibres, or containing at least 30% by weight thereof, comprises applying to the fibres an aqueous liquor which contains in solution a polymer containing copolymerised units of (a) acrylonitrile and (b) acrylic acid and its sodium or ammonium salt and drying and treated yarn, the said polymer containing units of (a) and (b) in the molar ratio of from 1:1.5 to 1:7 and, as determined in a 10% by weight aqueous solution at 20 DEG C., having a viscosity of 20 to 2000 cp and a pH value of 2.5 to 6.5, and containing 0 to 20% by weight of copolymerised units of other monomers, said monomers being soluble in water at 20 DEG C. in an amount of at least 2% by weight. The sizing liquor may contain conventional agents e.g. the starch ether employed in Example 7. In the examples the sizing liquors are applied to cotton yarn, red-dyed acrylic fibres, pale blue rayon staple/acrylic fibre blend yarns, linen warps, staple rayon yarns and polyester fibre/cotton blend yarns.
