摘要
探讨基于尿素的卤胺抗菌剂整理棉织物的效果。以环氧氯丙烷和尿素为原料合成一种卤胺抗菌剂前驱体(环氧尿素),然后将其通过轧烘焙的方式整理到棉织物上,采用红外光谱和扫描电镜对整理后的棉织物进行表征;通过滴定氯化后棉织物上的氯含量研究焙烘温度和整理剂浓度对处理效果的影响;测试了氯化后棉织物的抗菌性、水洗和储存稳定性及强力。试验表明:较理想工艺条件为环氧尿素质量分数6%,焙烘温度180℃,焙烘时间5min;氯化后的棉织物能在30min内杀死1×105 CFU^1×106 CFU的金黄色葡萄球菌和大肠杆菌,在水洗50次和储存30天后含氯量的保留率分别为50%和71%,并且失去的活性氯都能在次氯酸钠溶液的处理下恢复,且强力保留率能达到80%以上。认为:氯化后的棉织物具有良好的抗菌性能、耐水洗性能和储存稳定性,且强力损失较小。
The effect of halamine antibacterial agent based on carbamide using for cotton fabric finishing was discussed. One kind of halamine antibacterial agent precursor was synthesized by raw materials of epoxy ehloro- propane and carbamide. Then it is finished on cotton fabric by pad-dry-bake process. Infrared spectroscopy and scanning electron microscope were used for the evaluation of cotton fabric after finishing. The influence of baking temperature and finishing agent concentration on treatment effect was studied by chlorine content titration on cotton fabric after chlorination. Antibacterial property,washing, storing stability and strength of cotton fabric after chlorination were tested. The test results show that the ideal processing condition contains ethylene earbamide weight concentration as 6% ,baking temperature at 180 ℃ and baking time as 5 min. The cotton fabric after chlorination can kill staphylococcus aureus and Escherichia coli in the quantity of 1 ×10^5 CFU- 1 ×10^6 CFU within 30 min. After 50 times washing and 30 days storage,the retention rates of chlorine content are 50% and 71% respectively. Moreover,all the chlorine losing activity can recover after the treatment with sodium hypochlorite solu- tion. The strength retention rate is up to 80%. It is considered that antibacterial property, wash resistance and storage stability of cotton fabric after chlorination are better. The strength loss is smaller.
