摘　　要：为制备具有长效天然抗菌性的粘胶纤维水刺非织造布,选择以艾草精油-β-环糊精(WO-β-CD)微胶囊为抗菌剂,利用不同质量分数的纤维素溶剂N-甲基吗啉-N-氧化物(NMMO)对粘胶纤维非织造布进行溶胀和表面溶解处理,采用浸轧法将WO-β-CD微胶囊负载至粘胶纤维水刺非织造布上,制备天然抗菌非织造布,并对其进行结构表征和性能测试。结果表明:NMMO质量分数70%可将粘胶纤维溶胀,72%则会使粘胶纤维表面部分溶解,经溶胀和表面溶解处理后的非织造布可以有效负载WO-β-CD微胶囊,所得抗菌非织造布不仅具有良好的物理和力学性能,而且还具有长效抑菌效果。与未经溶胀溶解处理的WO-β-CD抗菌非织造布相比,溶胀和表面溶解处理后的WO-β-CD抗菌非织造布放置96 h后对大肠杆菌的抗菌率从80.4%分别提升至92.4%和96.3%,对金黄色葡萄球菌的抗菌率则从85.3%分别提升至96.4%和99.5%。The preparation of spunlace nonwoven fabrics with long-lasting natural antibacterial properties was achieved using wormwood essential oil-β-cyclodextrin(WO-β-CD)microcapsules as antibacterial agents.Different mass fractions of cellulose solvent N-methylmorpholine-N-oxide(NMMO)were utilized to swell and partially dissolve the surface of the viscose fiber nonwoven fabric.The WO-β-CD microcapsules were then loaded onto the viscose fiber spunlace nonwoven fabric using the padding method,resulting in the production of natural antibacterial nonwoven fabric,whose structure was characterized and performance was tested.The results indicate that a 70%mass fraction of NMMO can swell the viscose fibers,while a 72%mass fraction causes partial surface dissolution of the viscose fibers.The nonwoven fabric treated with swelling and surface dissolution was effectively loaded the WO-β-CD microcapsules.The resulting antibacterial nonwoven fabric not only possesses good physical and mechanical properties but also exhibits long-lasting antibacterial effects.Compared with the WO-β-CD antibacterial nonwoven fabric without swelling and dissolution treatment,the antibacterial nonwoven fabric treated with swelling and surface dissolution show an increase in antibacterial rate against Escherichia coli from 80.4%to 92.4%and 96.3%after 96 h,and against Staphylococcus aureus from 85.3%to 96.4%and 99.5%,respectively.
