Keratin solution and solid preparing process

Abstract

A process for preparing the solution and solid of ceratin includes extracting ceratin from wool of goat and sheep, camel hair, feather, leather leftover, etc by reduction method, and preparing solution and solid by use of the reagent, such as inorganic salt, urea, or thiourea.

Description

technical field [0001] The invention belongs to a regenerative protein utilization technology in the application field of natural polymer materials. It dissolves various keratin raw materials and makes them into solutions or solids for further processing and application. Its solution has remarkable characteristics, and its solid phase powder products have white color (when using non-colored raw materials), subunit Characterized by high molecular weight. Background technique [0002] my country is a big producer of goat hair, especially stimulated by the high profits of the cashmere industry, the total amount of goat breeding in my country has increased sharply, and the total number of goats in stock is about 160 million. However, the cashmere output in the raw cashmere produced by each goat is very limited, the cashmere content is less than 40%, and more than 60% is goat hair fiber with very low use value; along with the production and processing of cashmere, natural A lar...

AI Technical Summary

Problems solved by technology

However, the cashmere output in the raw cashmere produced by each goat is very limited, the cashmere content is less than 40%, and more than 60% is goat hair fiber with very low use value; along with the production and processing of cashmere, natural A large amount of goat hair fibers with very low use value are produced

However, the obtained polypeptides not only have low molecular weight and low production rate, but also have serious defects such as low concentration of keratin solution, protein variability, and high industrialization cost.
