Abstract

The invention relates to a preparation method and a dry-wet spinning method of a regenerated protein chitosan blended solution. The preparation method comprises the steps of: carrying out ultrafine grinding on raw materials of leftovers of reeling silks and leftovers of animal coarse hairs such as goat hairs, pig hairs, camel hairs and wools, dissolving the crushed raw materials in an ionic liquid to obtain a regenerated protein solution with high molecular weight, and blending the regenerated protein solution with a chitosan liquid to obtain a spinning solution. The spinning solution is molded by using a dry-wet spinning technology, the structure uniformity and the orientation degree of fibers are enhanced through solidification and drafting, and the elongation and the elasticity of the fibers are improved through oxidation crosslinking. The regenerated protein chitosan blended fiber has high protein content, and has functions of bacteria resistance, moisture prevention and promotion of blood coagulation and wound healing; and all compositions in the fiber are in biomass states, have good biodegradability and biocompatibility and can be applied to textile fibers and biomedical materials.

Description

Technical field [0001] The invention is the field of regeneration of biomass resources, involving a preparation method of recycled protein fiber containing chitosan, and specifically involves a regenerative egg with dry and wet spinning technology [0002] The method of preparation and wet wet spinning in white shell polycanic solution. Background technique [0003] Protein fiber has good hygroscopic absorption and anticidering performance, and has good affinity with human skin. In recent years, soybean protein, milk protein, and silkworm pupa protein fibers that have been processed by protein have been market -orientedEssenceHowever, the preparation of these protein fibers is co -concentrated or mixed by protein and synthetic polymers such as polyethylene glycols, polyacrylpines, etc., and the protein content in the fiber is very low.%, The main component is still a synthetic polymer, so the protein fiber is not a protein fiber in a complete sense, and it does not have the excel...
