摘　　要：为获得蓬松舒适的一次性卫生用品面层,以双组分皮芯结构聚乳酸(PLA)纤维为原料制备不同的热风非织造布,并与常规聚烯烃系(ES)纤维热风非织造布性能做对比,测试热风非织造布的拉伸性能、耐磨性能、透气透湿性能、液体穿透性能、抗菌性能及微生物降解性能。结果表明:相较于ES热风非织造布,PLA热风非织造布断裂强力、透气透湿性能略低,但仍满足一次性卫生用品标准要求;液体穿透性能及抗细菌性能更好;延长加热时间、提高热风温度可提高PLA热风非织造布的耐磨性和锁液能力;微生物降解140 d后降解率可达92.11%;综合性能更优。To obtain fluffy and comfortable surface layer of disposable sanitary products,different hot-air nonwovens were prepared using bi-component polylactic acid(PLA)fibers as raw materials,and their performance was compared with that of conventional polyolefin(ES)hot-air nonwovens.The tensile properties,wear resistance,air and moisture permeability,liquid penetration,antibacterial properties and microbial degradation properties of the hot-air nonwovens were tested.The results showed that,compared with ES hot-air nonwovens,PLA hot-air nonwovens had slightly lower breaking strength,air and moisture permeability,but which still met the standard requirements of disposable sanitary products.Better liquid penetration and bacterial resistance.Prolonging heating time and increasing hot-air temperature could improve the wear resistance and moisture lock capacity of PLA hot-air nonwovens.The decomposition rate reached 92.11%after 140 d of microbial degradation.The overall performance was better.
