摘　　要：为便于工业化生产,提高聚酯织物的抗菌性,将非水溶引发剂在水相中乳化,并对聚酯织物接枝3-丙烯基-5,5-二甲基-乙内酰脲抗菌单体。通过对乳化工艺进行讨论,并对接枝前后织物进行表征,再将织物氯化后进行抗菌性测试。结果表明:可将0.5%的引发剂稳定乳化并对织物进行整理;抗菌单体成功接枝到织物表面;相比于引发剂未乳化时织物的接枝率(0.046%),引发剂乳化后织物接枝率(0.489%)大幅提高,加入交联剂进行整理,织物接枝率(1.023%)进一步提高;织物对金黄色葡萄球菌的抗菌率可达80%,引发剂乳化后与交联剂联合整理的织物抗菌率达96%。In order to facilitate the industrial production and improve the antibacterial property of polyester fabrics, the insoluble initiator was emulsified in water to graft 3-allyl-5,5-dimethyl-hydantoin （ADMH） to polyester fabric. The fabrics before and after grafting were characterized, and the fabrics were chlorinated and subjected to antibacterial testing by pad-cure processing according to the AATCC standard. The results show that under the conditions 0.5% initiator can be stabilized and emulsified and then used for fabric finishing; antibacterial monomer is successfully grafted on the fabric surface; compared with the grafting ratio of fabric of 0. 046% using unemulsified initiator, the grafting ratios of polyester fabric using emulsified initiator is greatly improved to 0. 489%, and by finishing with erosslinking agent, the grafting ratio is further improved to 1. 023%. The fabric has the antibacterial ratio to 10^5 CFU/mL Staphylococcus aureus up to 80%, and the antibacterial ratio of modified polyester finished with crosslinking agent is up to 96%.
