聚硅氧烷季铵盐微乳液的织物抗菌性能研究

目的探讨聚硅氧烷季铵盐微乳液的抗菌性能。方法以大肠杆菌、金黄色葡萄球菌和白色念珠菌为考核菌,采用抑菌圈法和振荡烧瓶法定性和定量检测抗菌整理剂的效果。结果聚硅氧烷季铵盐微乳液的最低抑菌浓度为2%,对金黄色葡萄球菌的抑菌效果优于大肠杆菌,对酵母菌亦有较好的抑菌效果,纯棉坯布对金黄色葡萄球菌的抑菌效果最佳,洗涤30次后抑菌率仍高达92.34%,保存6个月后其抑菌率仍保持99.96%。结论经聚硅氧烷季铵盐微乳液整理的纯棉坯布抗菌性能好,具有一定的抗菌耐洗性和稳定性。

Antibacterial Performance of Fabric Treated with Siliconequaternary Ammonium Microemulsion

Objective To study the antibacterial performance of the fabric treated with siliconequaternary ammonium microemulsion.Methods Escherichia coli,Staphylococcus aureus and Candida albicans were used as the test bacteria and the method of bacteriostasis circle,vibration flask were used to test the effects of the antibacterial agent qualitatively and quantitatively.Results The lowest bacteriostasis concentration for siliconequaternary ammonium microemulsion was 2%,the bacteriostasis effect on staphylococcus was superior to that on E.coli and it had a good bacteriostasis effect on the yeast.Pure cotton bacteriostasis effect was most noticeable in its antibacterial reorganization and it reached 92.34% of the bacteriostasis rate after washed for 30 times,and the bacteriostasis rate for the treated fabric could still keep 99.96% after 6 months of preservation.Conclusion The fabric reorganized with the siliconequaternary ammonium microemulsion has a good capacity of bacteriostasis and washes well in antibacterial performance.
