| titleOfInvention | Method of obtaining polysaccharide material |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of obtaining polysaccharide fibre for making materials, specifically for making surgical suture materials absorbable in a human and a mammal body, absorbable and non-absorbable dressing material and absorbable textile matrix materials. The method is characterised by that 2.4-4.0 wt % solution of polysaccharide in dimethylacetamide which contains 4.56-10.00 wt % lithium chloride is mixed with 1.0-5.0 wt % poly-N-vinylpyrrolidone with molecular weight of 8-35 kDa or a metallopolymer complex - fine-grained silver stabilised by poly-N-vinylpyrrolidone in such an amount that, content of fine-grained silver relative polysaccharide dissolved in spinning solution ranges from 0.07 to 0.87 wt %. Mass ratio of polysaccharide: metallopolymer complex equals 88.0-99.0:1.0-12 wt %. The mixture is intensely stirred, held, filtered, degassed and the obtained spinning solution is extruded at room temperature into an alcohol deposition tank in form of water-soluble aliphatic C 2 and C 3 alcohols. The fibre is then processed in plastification and washing tanks and dried. n EFFECT: obtaining fibre with good deformation and strength properties. n 1 dwg, 4 tbl, 29 ex |
