天然高分子对化学纤维涂覆改性的新方法

The New Methods of Chemical Fibers Modification by Coating Natural Polymers

介绍了采用天然高分子对化学纤维进行涂覆,从而改善化学纤维亲水性的方法。主要包括壳聚糖和海藻酸盐的溶胶-凝胶法。壳聚糖和海藻酸盐分子链上都含有大量的羟基等亲水性基团,利用它们的溶解性质可将其均匀地涂覆在化学纤维表面,从而对化学纤维进行亲水化改性。

In this paper, the new methods of coating a layer of natural polymers onto chemical fibers to make them to be hydrophilic were introduced; it included sol-gel methods of chitosan and alginate. There are abundant hydrophilic groups such as hydroxyls in the molecular chains of chitosan and alginate. Chitosan and alginate can be coated uniibrmLy onto the chemical fibers by using their special dissolving properties, and then the hydrophobic surface of chemical fibers will be modified to be hydrophilic.
