Abstract

The present invention discloses oxidation process of preparing wool keratin solution, and the preparation process can maintaining the physical and chemical performance of wool and has raised solubility and lowered wool dissolving temperature. The preparation process includes the following steps: washing and stoving wool; preparing wool dissolving solution through adding urea into H2O2 to obtain adduct, mixing the adduct with distilled water and adding anionic surfactant via stirring to obtain transparent liquid as the wool dissolving solution; mixing wool dissolving solution and wool in the weight ratio of 5-20 to 1 via stirring, heating to 65-85 deg.c and maintaining for 4-6 hr to obtain yellowish translucent liquid and filtering to eliminate insoluble impurity and obtain wool keratin solution. The process is simple and low in cost.

Description

technical field [0001] The invention relates to a method for preparing a wool keratin protein solution, in particular to a method for preparing a wool keratin protein solution by an oxidation method. Background technique [0002] The regeneration and utilization of natural protein fibers has become a hot issue nowadays, and has attracted the attention of researchers from all walks of life, and the regeneration and utilization of wool keratin protein is the most active field of research. After the waste wool is dissolved, it is prepared into wool keratin protein solution, which can be processed into fibers of various specifications by artificial spinning technology, and can also be used as a finishing agent for textiles, endowing other textiles with the physical and chemical properties of wool fibers . The prepared wool keratin protein solution is also widely used in hair care, skin care products and nutritional additives for animal feed. At present, there are two main ways...
