Ding, Sheng; Zhu, Jinxing; Tian, Saiqi published the artcile< Polyurethane-based retanning agents with antimicrobial properties>, Category: esters-buliding-blocks, the main research area is polyurethane retanning agent antimicrobial property.
Polyurethane-based retanning agents with antimicrobial properties were synthesized by the chem. incorporation of ciprofloxacin (CPFX) units into polyurethane chains. The chem. structures were characterized by Fourier transform IR (FTIR) and gel permeation chromatog. (GPC). Then, the retanning agents were applied in the leather retanning process. Owing to the conjugation of CPFX into polyurethane chains, the mol. weight increases, further leading to the decrease in hydroxyl value and increase in particle size. The shrinkage temperature was improved after retanning. Owing to the filling of retanning agents in the gap of collagen fibers, the average thickness of leather increased by 65.8%. The mech. properties of leather were visibly improved because of the large number of -COOH coordinate with Cr3+ and more hydrogen crosslinking with carboxyl group, amino group, and hydroxyl group of leather collagen. Furthermore, leather retanned by these polyurethane-based retanning agents presented good antimicrobial properties. The antibacterial activity could be conserved above 89% even after rinsing for ten times.
