活性壳聚糖季铵盐的制备及其对棉织物的功能整理
Preparation of active chitosan quaternary ammonium salt and its functional finishing on cotton fabric
摘要
Abstract
In order to realize the covalent grafting of chitosan quaternary ammonium salt(HTCC)and cotton fabric,synthesis of active chitosan quaternary ammonium salts(TCT-HTCC)and their application effects on cotton fabrics were studied.HTCC was synthesized by homogeneous reaction using 1-allyl-3-methylimidazolium chloride ionic liquid as solvent.Two different dispersants,octadecyltrimethylammonium chloride(STAC)and N-dodecyl-2-pyrrolidone(N-DP),were used to disperse melamine(TCT).TCT-HTCC was synthesized by heterogeneous reaction,and covalent grafting of HTCC and cotton fabric was achieved through nucleophilic substitution reaction.The structure and property of HTCC,TCT-HTCC and modified cotton were characterized using infrared spectroscopy and XPS.The results showed that dispersants were beneficial for the grafting of melamine onto HTCC.Among them,the TCT-HTCC modified cotton fabric synthesized using dispersant octadecyltrimethylammonium chloride had antibacterial rates of 99.9%against Escherichia coli and Staphylococcus aureus,free radical scavenging rate of 30.34%against ABTS,and K/S value of 2.161 6 for cotton fabric dyed with natural dye Sophora flavescens.It is believed that TCT-HTCC prepared by using dispersed system can enhance the antibacterial,antioxidant and dyeing property of modified cotton fabrics.关键词
