改性纳米银抗菌剂与改性季铵盐抗菌剂对口罩面料抑菌效果的比较研究

Comparative Study of Bacteriostatic Effect of Mask Fabric Treated with the Modified Nanometer Silver Antibacterial Agent and the Antimicrobial Agent of Modified Quaternary Ammonium Salt

本文分别采用改性纳米银抗菌剂和改性季铵盐抗菌剂对口罩面料进行了抑菌处理,采用吸收法对抑菌处理后样品及抑菌处理后的洗涤样品进行了抗菌效果检测,结果表明改性纳米银抗菌剂对金黄色葡萄球菌和大肠杆菌的抑菌率均达到99%以上,改性季铵盐抗菌剂的抗菌效果不如改性纳米银抗菌剂更为稳定,而在抑菌处理后经过洗涤的样品,只有改性季铵盐抗菌剂处理样品的抑菌率达到99%。

The modified nanometer silver antibacterial agent and the antimicrobial agent of modified quaternary ammonium salt have been used to give an antibacterial treatment for mask fabric. With the method of absorption, the sample through antibacterial treatment and the antibacterial samples washed were used to test antibacterial effect. Results show that the antibacterial rate of modified nanometer silver antibacterial agent toward e.eoli and staphylococcus aureus can reach to 99%. The antibacterial effect of the modified nanometer silver antibacterial agent is more stable than the antimicrobial agent of modified quaternary ammonium salt. Only the mask fabric handled by modified quaternary ammonium salt antibacterial agent the bacteriostasis rate up to 99% of the sample after washing of the sample.
