| 摘 要： | 为评价氯胺抗菌织物在公共卫生领域作为清洁布的实用抗菌效果，采用3-烯丙基-5,5-二甲基乙内酰脲(ADMH)处理涤纶/锦纶超细纤维针织物，以活性氯含量为指标，确定了制备氯胺织物的最佳活化工艺：次氯酸钠溶液活性氯含量3 000 mg/kg,浸泡时间20 min, 60℃下烘干20 min。测试了氯胺织物对金黄色葡萄球菌和大肠杆菌的抗菌性能以及对甲型流感病毒H1N1的抗病毒性能，并将其用于医院重症加强护理病房(ICU)设施和公共食堂餐桌擦拭清洁。结果表明：活化氯胺织物对金黄色葡萄球菌和大肠杆菌接触3 min时，抑菌率均达到99.999%,对H1N1的抗病毒活性率达到99.94%;经过擦拭的ICU设施表面细菌量为零，氯胺抗菌织物连续擦拭30张桌面后桌面和擦拭织物均不带菌，且氯胺抗菌织物具有良好的活化再生功能。

| Abstract: | In order to evaluate the practical antimicrobial effect of chloramine fabrics as wiping cloths in the field of public health,the optimal chloramine fabric activation process of polyester/polyamide microfiber fabric grafted with 3–allyl–5,5–dimethylhydantoin (ADMH) was investigated based on the content of active chlorine on the fabric. The optimal activation process was reached when the active chlorine concentration of sodium hypochlorite solution was 3 000 mg/kg, the soaking time was 20 min, and the fabric was dried at 60 ℃ for 20 min. The chloramine fabric was tested for antibacterial performance against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), and for antivirus property against influenza A virus H1N1. The treated fabric was used for wiping the intensive care unit (ICU) ward facilities in a hospital and public canteen dining tables. The results show that the antibacterial ratio against both S. aureus and E. coli reaches 99.999％, and the antiviral activity ratio against H1N1 is 99.94％. The amount of residual bacteria on the surface of the cleaned ICU facility is zero. After wiping thirty dining tables successively with the same chloramine fabric, neither the surfaces of the wiped 30 dining tables nor the wiping fabrics were found to be contaminated with bacteria. Moreover, the chloramine fabric shows a good activation and regeneration property of active chlorine when it is treated with sodium hypochlorite solution. |
