摘　　要：以还原染料染色的纯棉织物为基材,选用季铵盐、有机胍、氯化银、二氧化钛4种抗菌剂,选取抗菌剂用量、轧液率、焙烘温度3个因素进行正交实验,以大肠杆菌的抗菌效果为评价指标,优化抗菌整理工艺。结果表明,在每种抗菌剂的优化工艺条件下,有机类抗菌剂整理棉织物的抗菌效果优于无机类抗菌剂,其中有机胍抗菌剂对大肠杆菌的抑菌率最高,达到99.8%,二氧化钛抗菌剂的抗菌性能低于其他3种抗菌剂。洗涤10次后,季铵盐抗菌剂整理织物的抑菌率下降到34.1%,其余两种抗菌剂抑菌率在49.0%左右,耐洗性均需要提升。Pure cotton fabrics dyed with vat dyes were chosen as the substrate,four antibacterial agents,namely quaternary ammonium salt,organic guanidine,silver chloride and titanium dioxide antibacterial agent were used for antibacterial finishing.Three factors of agent concentration,rolling rate and baking temperature were selected for orthogonal experiment.The antibacterial effect of Escherichia coli was used as the evaluation index to optimize the antibacterial finishing process.The results showed that under the optimized process con⁃ditions of each antibacterial agent,the effect of organic antibacterial agent finished cotton fabric was better than that of inorganic antibacterial agent.Among them,organic guanidine antibacterial agents had the highest antibacterial rate against Escherichia coli,reaching 99.8%,while titanium dioxide antibacterial agents had lower antibacterial performance than the other three antibacterial agents.After washing 10 times,the antibacterial rate of the fabric treated with quaternary ammonium salt antibacterial agent decreased to 34.1%,while the oth⁃er two antibacterial agents were around 49.0%.The washing resistance of all agents needs to be improved.
