Synthesis and Properties of Multi-Functional Leather Finishing Agent

Abstract:

With the collagen hydrolyzate by alkali extraction from chromium-containing shavings as raw material, the protein leather finishing agent is prepared in this work. The monomers of acrylic acid series and namo-TiO2 are applied in physical and chemical modification of the collagen. The structure of the protein finishing agent is characterized by IR. The optimum technological conditions are determined by the orthogonal tests. The remarkable characteristics of this method were the lower bromine number, the better chemical and mechanical stability, and the better repeatability of the product. The resistance to dry and wet rubbing fastness and water resistance of the protein finishing agent are superior to that of the conventional leather finishing agents. The protein finishing agent has also antimicrobial performance.
