摘要
采用胶原蛋白溶液对经高碘酸钠有限氧化处理的棉纤维进行化学改性,制备了胶原蛋白交联棉纤维。运用傅里叶红外光谱和光电子能谱研究胶原蛋白与棉纤维的交联机理,并分析了胶原蛋白浓度、处理时间、反应温度、溶液pH值等因素对交联效果的影响以及经胶原蛋白处理后棉纤维的性能。胶原蛋白交联棉纤维的优化工艺为：胶原蛋白用量1%-2%,反应温度35-40℃,处理时间1 h,pH值4-5,高碘酸钠质量浓度1 g/L。处理后棉纤维断裂强力有所提高,断裂伸长率略有降低,初始模量增大,弹性变形增加。
Cotton fabric was oxidized with sodium periodate followed by collagen modification. The crosslinking mechanism of cotton fiber was investigated by Fourier transform infrared spectra and X-ray photoelectron spectrometry. Influences of dosage of collagen, reaction time and temperature, pH value of the collagen solution on crosslinking results and the properties of cotton fiber were analyzed. The optimum process was determined as follows： collagen 1 % - 2%, reaction at temperature 35 - 40℃ for 1 hour, pH value 4-5, sodium periodate 1 g/L. It was found that collagen modified cotton fiber featured increased breaking strength, decreased breaking elongation, increased initial modulus and elastic deformation.
