Method for preparing highly porous composite fibers of dibutyrylchitin

摘要

method of manufacturing composite wysokoporowatych fibres with dibutyrylochityny is, to an aqueous solution of ethanol concentration of 62 to 96% by weight containing 15 - 18% by weight dibutyrylochityny viscosity material 1,6 - 2,8 dl / g, with the possible addition of glycerol in quantity of 0.1 - 15% by weight ch in relation to dibutyrylochityny, at 10 - 30 oc,introduces when mixing the hydroxyapatite nanoparticles and / or tricalcium phosphate or their homogeneous dispersion of 10 - 25 degrees celsius temperature, quantity of 0.1 - 100% by weight in relation to dibutyrylochityny.subsequently the mixture is subjected to further mixing for 15 to 60 minutes, after which it obtained solution spinning, after odpowietrzeniu, it cuts through wielootworowu0105 filieru0119 bath koagulacyjnej temperature 25 - 45u00b0c, which is the aqueous solution of ethanol at a concentration of 0.2 - 5.0%. gowych and ph in the 1 - 9.fibre forming using extract filierowego for 0.2 - 3.0, and the obtained fibers are 1,2 - 3.5 times the stretch in the water bath temperature of 80 - 95u00b0c or in solution of sodium hydroxide at a concentration of 0.1 - 0.5% by weight.
