Production method of sheep protein fibers

Abstract

The invention relates to the technical field of protein fibers, in particular to a production method of sheep protein fibers. The production method comprises the following steps that firstly, impurities are removed and wool is sterilized, then the wool is prepared and placed in a solution, then side chain modification and grafting are carried out, then filtering and defoaming treatment are carried out, and finally spinning is carried out to obtain a finished product. By using the waste wool, more resources are relatively saved, and the step of sterilization is additionally arranged before the protein solution is prepared, so that bacteria contained in the waste wool are prevented from affecting the subsequent working procedures; a proper amount of Fmoc groups and tert-butyl are added in the spinning step and can protect serine and threonine from being dissolved, so that the content of protein in the sheep protein fiber is increased; and a proper amount of antistatic agent and wool oil are added in the last step, so that the friction coefficient between the sheep protein fibers is greatly reduced, and the high electrostatic property of original wool is avoided.

Description

technical field [0001] The invention relates to a production method of protein fiber, in particular to a production method of sheep protein fiber, and belongs to the technical field of protein fiber. Background technique [0002] Protein fiber is a category of man-made fiber, which refers to the fiber made from protein extracted from natural things such as milk, soybeans, peanuts, and corn, and dissolved in an appropriate solvent, while sheep protein fiber is made from wool Extracted protein fibers. [0003] However, in the production process of sheep protein fiber, some wool waste will be discarded, which is not enough to save resources. In addition, in the production process of sheep protein fiber, the protein of wool needs to be hydrolyzed into amino acids, some of which are small molecular amino acids. They will be dissolved into the coagulation bath in the subsequent process of making solid fibers, especially serine and threonine, both of which will be completely disso...

[0003] However, in the production process of sheep protein fiber, some wool waste will be discarded, which is not enough to save resources. In addition, in the production process of sheep protein fiber, the protein of wool needs to be hydrolyzed into amino acids, some of which are small molecular amino acids. They will be dissolved into the coagulation bath in the subsequent process of making solid fibers, especially serine and threonine, both of which will be completely dissolved, resulting in a difference in texture between the obtained sheep protein fiber and wool. In addition, the current Some sheep protein fibers retain the disadvantage of high static electricity of wool after being made
