摘　　要：用γ-氯丙基三甲氧基硅烷与二乙胺反应,经季铵化反应制得抗菌剂GD-1,并对纯棉织物进行抗菌整理,测试整理后织物的抑菌率、白度、断裂强力、折皱回复角等性能.整理后棉织物对大肠杆菌和金黄色葡萄球菌的抑菌率分别为99.74%和99.37%,自制抗菌剂GD-1的最佳应用工艺为:GD-1用量20g/L,pH=6,80℃预烘,120℃焙烘.整理后的棉织物洗涤50次后,抑菌率仍能保持在80.95%左右.With γ-chloropropyl trimethoxysilane and diethylamine reaction ,the antibacterial GD-1 is ob-tained through quaternization reaction ,and antibacterial finishing process is applied on cotton fabric . Then the finished fabric inhibition rate ,whiteness ,breaking strength ,wrinkle recovery angle and other properties are tested .The results show that the antibacterial rate of Escherichia coli and Staphylococcus aureus on finished cotton fabric reached 99.74% and 99.37% .GD-1′s best application processes are as follows ：GD-1 dosage of 20g/L ,pH=6 ,80 ℃ pre-baking ,120 ℃ baking .After washing 50 times ,the antibacterial rate of the finished cotton fabric is still able to remain at about 80.95% .
