Abstract
The surface modification process for cotton fabric which was oxidized first, and then crosslinked with collagen was studied. The optimum oxidation process was as follows: concentration of sodium periodate 0.6g/L, time 2.5h, temperature 40°C, ratio of water and cotton fabric was 100:1. The method for surface modification of cotton fabric was determined from comparative analysis, and the optimum process: collagen solution concentration 6%, glutaraldehyde concentration 5%, reaction 40min at 30°C, ratio of water and cotton fabric was 100:1. Compared with original cotton fabric,the breaking strength and elongation of collagen modified cotton fabric decreased, while the dyeing percentage with acid dyes was increased and this means the surface of modified cotton fabric was covered with a large component of collagen.
