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.

The core-shell acrylic resin emulsion is prepared by seed polymerization technology, with styrene, methyl methacrylate, acrylonitrile as monomer, butyl acrylate, methyl methacrylate, acrylic acid as shell monomer, and the of nanoTiO2 is introducted in shell emulsion. Infrared spectroscopy were used to characterize the structure of the prepared coating agent. The preparation of TiO2/acrylic resin emulsion for leather finishing agent, and discusses its influence on the leather properties. The results show that the synthetic finishing agents for dyeing after the fatliquoring leather finishing, good finishing effect can be obtained.

A novel hyperbranched polyurethane (HBPU) finishing agent was prepared by graft copolymerization of hyperbranched poly (amine-ester) polyols (HPAE) and the isocyanate-terminated polyurethane prepolymer(PPU). The PPU was synthesized by step polymerization of isophorone diisocyanate (IPDI) with polyethylene glycol (PEG) and dibutyltin dilaurate (DBTDL) as catalyst. The FT-IR spectroscopy was used for the structural characterization. The thermal properties of HBPU were characterized by TGA. Microphase separation of HBPU film surface was studied by tapping-mode atomic force microscopy (AFM). Moreover, in contrast to 200-UT, the physical and mechanical properties of HBPU as finishing agent were investigated: curing time was decreased by 26.15% and the water vapor permeability was increased by 9.04%.
