摘　　要：为赋予聚丙烯非织造材料良好的抗菌、抗病毒性能,采用等离子体技术进行亲水前处理和抗菌、抗病毒浸轧后整理,同时对整理后材料的舒适性能、抗菌性能及抗病毒性能进行测试。结果表明:在等离子体处理工艺参数为气体流量5mL/min、处理功率75W、处理时间180s时,整理后试样透气率从原样的2302mm/s大幅度提升至2609mm/s;整理后试样对大肠埃希菌和金黄色葡萄球菌的抑菌率分别为99.39%和99.99%,表现出较好的抗菌效果;整理后试样的抗病毒活性率由86.90%提升至99.99%及以上,表现出良好的抗病毒效果。该工艺成功赋予了聚丙烯非织造材料抗菌、抗病毒功能,为后续医用防护用品开发奠定试验基础。In order to endow polypropylene nonwoven materials with good antibacterial and antiviral properties,plasma technology is used for hydrophilic pretreatment and antibacterial and antiviral dip finishing.At the same time,the comfort,antibacterial and antiviral properties of the finished materials are tested.The results show that the air permeability of the finished sample is greatly improved from 2302 mm/s to 2609 mm/s under the condition of plasma treatment process with gas flow rate of 5 mL/min,treatment power of 75 W and treatment time of 180 s.The antibacterial rates of the finished samples against Escherichia coli and Staphylococcus aureus are 98.89%and 99.99%,respectively,showing a good antibacterial effect.The antiviral activity rate of the finished sample increases from 86.90%to more than 99.99%,showing a good antiviral effect.This process has successfully endowed polypropylene nonwoven materials with antibacterial and antiviral functions,laying a foundation for the subsequent development of medical protective equipment.
