Antibacterial Performance of Fabric Treated with Siliconequaternary Ammonium Microemulsion / 环境与健康杂志

ABSTRACT

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.
