FIELD: textile industry. ^ SUBSTANCE: invention relates to technology of treating genuine and synthetic fibrous materials to protect their surface against growth of microorganisms and can find use in manufacture of decorative and finishing or structural materials for spatial objects, in different forms in submarines, in surface or underground tightly sealed rooms, and in precision objects (e.g. electronics) assembly shops. Method comprises radiation graft polymerization of vinyl carboxylic acid from vapors thereof upon irradiation of the yarn with gamma-emission source (60Co), neutralization of carboxylic groups of grafted poly(vinyl carboxylic acid) through soaking in aqueous solution of sodium or potassium hydroxide, carbonate, or bicarbonate, and immobilization of alkyl(benzyl)dimethylammonium cation as counter ion. ^ EFFECT: provided prolonged protection of fibrous materials against attacks of microorganisms. ^ 5 tbl, 15 ex |
