(57) [Summary] [Purpose] It is advantageous for storage, transportation and use, A method for sizing a textile fiber yarn using a powdery copolymer that is bioenvironmentally and toxicologically acceptable. [Structure] As a sizing agent for textile fiber yarns, a) acrylic acid ester and / or methacrylic acid ester 40 to 9 0% by weight, b) a monoethylenically unsaturated C 3 -C 5 carboxylic acid, maleic acid, fumaric acid or a half-ester of a monovalent C 1 -C 4 alcohol with itaconic acid, or a monomer thereof. Mixtures 10 with up to 55% by weight of other water-soluble monomers ˜35% by weight, c) a suspension polymer consisting of 0-30% by weight of another water-insoluble monomer in an aqueous solution or suspension in a form at least partially neutralized with a base. use. |
