利用脲的热分解产物异氰酸与织物表面羟基的反应，制备了表面含氨基甲酸酯基团的棉织物；经稀次氯酸钠溶液漂洗后，表面可生成N-氯胺基甲酸酯，赋予织物抗菌性。研究了氨基甲酸酯化(酯化)条件对织物含氮量的影响，采用抑菌圈法和振荡法测试了改性织物对大肠杆菌和金黄色葡萄球菌的抗菌性。结果表明，酯化后，棉布表面生成了氨基甲酸酯基团。随酯化温度提高或酯化时间增加，织物含氮量均先增加后降低；浸渍液中脲浓度和织物带液率的增加均有利于改性织物含氮量的提高。织物经稀次氯酸钠溶液漂洗后，在织物表面生成了氯胺。氯化后的棉织物对大肠肝菌和金黄色葡萄球菌显示出有效和强大的杀灭能力。

Fabric with carbamate group on surface was prepared by reacting the hydroxyl group on fabric with isocyanic acid which is the product of heat decomposition of urea;the carbamate groups were transformed to be N-chlorocarbamates by exposing them to dilute sodium hypochlorite solution, which renders the fabric biocidal. The effect of carbamatization technology on nitrogen content of fabrics was studied. Antibacterial activities of the modified fabrics against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were evaluated according to the Inhibition zone method and Flask-shake method, respectively. The results show that carbamate group is formed on fabric surface after carbamatization. With carbamatization temperature rise or time extendence, nitrogen content on fabrics increases firstly and then drops. Increase of liquid retain ratio or urea concentration in dipping solution is helpful for increasing the nitrogen content on the modified fabric. Chloramines are formed on fabric surface after bleaching it with dilute sodium hypochlorite solution. The bleached cotton fabrics show effective and strong sterilizing ability against E. coli and S. aureus.
