FIELD: textile industry.
SUBSTANCE: invention relates to fabrication of artificial fibers possessing antibacterial activity, in particular to fabrication of chitosan-containing fibers. Process comprises preparation of solution of chitosan in acetic acid, to which concentrated sodium hydroxide solution is added in order to perform mercerization. Mercerized chitosan is then subjected to xanthogenation to produce chitosan viscose. The latter is molded, finished, and dried. According to second option, thus obtained chitosan viscose is blended with cellulose viscose followed by molding, finishing, and drying resulting chitosan-containing blend. According to third option, chitosan-containing alkali solution is supplemented by pulped cellulose for subsequent joint mercerization, xanthogenation, finishing, and drying.
EFFECT: imparted antibacterial activity.
