利用卤胺载体氯化三甲基铵乙酰肼(GT)与三聚氯氰(CYCH)间的亲核反应,制得二氯三嗪类卤胺抗菌前驱体2,4-二氯-6-(乙酰氨基-胺基)三甲基氯化铵-1,3,5三嗪(DTCT)。经低温活性染料染色工艺将DTCT接枝到棉织物上,氯化得到了新型抗菌棉织物(Cotton/DTCT-Cl)。通过红外光谱、扫描电镜验证了抗菌棉织物的成功制备。研究了整理前后棉织物的断裂强力及氯化后织物的抗菌效果。综合各项测试发现,此方法在保证高效抗菌的同时较好地保留了织物的力学性能。
Novel kind of dichlorotriazine N-halamine antibacterial precursor 2,4-dichloro-6-(acetamino-amine) trimethylammonium chloride-1,3,5 triazine (DTCT) was prepared by the nucleophilic reaction between Girad's reagent T (GT) and cyanuric chloride (CYCH).The DTCT compound was grafted onto cotton fabric through the finishing process of active dyestuff at low temperature,and the antibacterial cotton fabric was prepared after chlorination processing.The successful preparation of the grafted fabric was determined by analyzing the FT-IR and SEM images.The breaking strength of different fabrics and the bactericidal efficacy of chlorinated DTCT treated cotton fabric were studied as well.Taking into account all the results,the finishing method can not only guarantee the effective antibacterial effect but also retained the mechanical properties of the fabric.
