摘　　要：采用自制的纳米ZnO整理剂制备了负载纳米ZnO非织造布,利用Zeta电位及粒径分析仪研究了整理剂的Zeta电位、纳米ZnO的粒径大小和分布;运用原子力显微镜(AFM)研究了负载于非织造布上纳米ZnO颗粒分布情况。研究结果表明:整理剂中ZnO颗粒的平均粒径小于100 nm,整理后非织造布上颗粒粒径大都小于100 nm。负载纳米ZnO非织造布具有良好的光催化性能和一定的耐洗性,经洗涤8次后,其光催化性能依然保持在50%以上;在相同的条件下,采用含有丙烯酸酯黏合剂的纳米ZnO整理剂处理后的非织造布耐洗牢度较好。Nonwovens loaded with nano-ZnO was prepared with nano-ZnO finishing agent.Zeta particle size and potential analyzer was used to examine the Zeta potential,nano-ZnO particle size and distribution of the finishing agent.Atomic force microscopy（AFM） was employed to study the distribution of nano-ZnO on nonwovens.The results revealed that the average particle size of nano-ZnO finishing agent was less than 100 nm,and most of the particle sizes on nonwovens after treatment were less than 100 nm.The nonwoven materials loaded with nano-ZnO had good photocatalytic performance and washability.The photocatalytic reactivity still maintained above 50% after 8 times washing.Under the same experimental conditions,the nonwoven materials treated with nano-ZnO finishing agent containing acrylate adhesive had better washing fastness.
