摘要：
FIELD: medicine.SUBSTANCE: composition of forming solution for formation of biopolymeric fibres includes polyethylene oxide, chitosan, organic acid and water. Or composition of forming solution for formation of biopolymeric fibres includes chitosan, water and component, selected from polyethylene oxide, polyvinyl alcohol or polyvinylpyrrolidone. Chitosan with molecular weight 30-40 kDa and polyethylene oxide with molecular weight 2000-8000 kDa are used. Composition additionally contains cellulose diacetate and biologically active substances. Method of forming solution preparation includes mixing of components in powder-like state and their dissolution with mixing to homogenous state. Linen of biomedical purpose, formed from biopolymer chitosan-based fibres, in order to obtain from it bandage for wound treatment, is subjected to swelling in physiological solution or distilled water. Additionally linen of biomedical purpose is subjected to thermal processing, after which it is placed into distilled water or physiological solution for swelling. Or linen is additionally processed with alkaline reagent, with further washing with distilled water, after which it is placed into distilled water for swelling. For wound treatment linen of biomedical purpose is applied on wound in form of biological bandage.EFFECT: invention makes it possible to obtain biopolymer fibre with application of optimal compositions of textile composition based on chitosan and non-toxic polymer for stable electroformation of defect-free fibres, methods of modification of linen of biomedical purpose for obtaining bandage in form of wound covering are ecologically clean and economical.2 tbl, 73 ex, 5 dwgИзобретение относится к получению биополимерных волокон из хитозана методом электроформования и нетканого волокнисто-пористого материала на их основе для получения полотна биомедицинского назначения в качестве биологической повязки для лечения ран.
