摘　　要：研究可重复使用医用防护服织物洗消灭菌前后防护性能、舒适性能及机械性能的变化,分析影响可重复使用医用防护服织物耐洗消灭菌性能的主要因素。结果表明:重复洗消灭菌前后医用防护服织物的过滤效率均在97.0%以上,抗合成血液穿透性能均在6级以上;重复洗消灭菌处理后防护服织物断裂强力有所下降,撕破强力显著降低;透气性能、耐磨性能与表面电荷面密度变化均不明显;重复洗消灭菌后防护服织物抗渗水性能下降,表层织物薄,聚四氟乙烯膜薄,导致静水压值下降;防护服织物透湿率有所下降,聚四氟乙烯膜的厚度是影响透湿率变化的主要因素,厚度增加则透湿率下降幅度减小。The changes on the protective,comfort and mechanical performance of reusable medical protective clothing fabrics before and after sterilization are studied.The main factors affecting the washing,disinfection,and sterilization performance of reusable medical protective clothing fabrics are revealed.The results show that the filtration efficiency of medical protective fabrics before and after repeated washing and sterilization is above 97.0%,and the anti-synthetic blood penetration is above level 6.After repeated washing and sterilization treatment,the breaking strength of the protective fabric decreases,and the tearing strength significantly decreases,and the air permeability,wear resistance and surface charge density do not change significantly.The hydrostatic pressure of the protective fabric declines.The surface fabric is thin or the polytetrafluoroethylene film is thin,leading to a decline in hydrostatic pressure,the moisture permeability of protective fabrics decreases,and the thickness of polytetrafluoroethylene film is the main factor affecting the change in moisture permeability.As the thickness increases,the decrease in moisture permeability reduces.
