棉织物作为毛巾、衣服等有较好的吸水性和柔适性,但容易成为微生物滋生繁衍的场所,从而影响人们的生活健康,采用机械混合法制备出AgO/TiO2复合粉末;采用激光粒度仪对AgO/TiO2复合粉末进行了粒度分布分析;然后利用后整理法加工出载AgO/TiO2抗菌棉织物,对整理棉织物的物相组成进行XRD分析,并测试了整理棉织物的抗菌效果。结果表明,AgO/TiO2复合粉末粒径细小、比表面积高,粒度分布为0.286～11.740μm,比表面积为442.37m2/kg;经AgO/TiO2复合粉末整理后,棉织布上附着有颗粒,颗粒以AgO形式存在;整理后棉织物具有强的抗菌效果和好的耐洗性,其对大肠杆菌的抑菌带宽度为1.075cm,杀菌率为100%;经过20次洗涤后,整理棉织物的抑菌带宽度为0.78cm,杀菌率为99.998%。
Cotton texture used as towel and clothing exhibits good hydroscopicity and flexible. However, cotton texture was favor to be the location of microorganism propagation, further affects more and more people. Therefore, AgO/TiO2 composite powders were synthesized by mechanical mixing in this paper. The size distribution of AgO/TiO2 composite powders was analyzed by laser particle sizer. After that, antimicrobial cotton texture with AgO/TiO2 was manufactured by hereafter disposal. The phase composition of the treated cotton texture was analyzed by X-ray diffraction, and the antibacterial effect was tested. The results show that the size of AgO/TiO2 composite powders was fine, and the specific surface area is high, which is distributed in the range of 0. 286-11. 740μm, and is 442.37m2/kg, respectively. After finishing with AgO/TiO2 composite powders, there are particles attached to cotton texture, which exists in the form of AgO. The treated cotton texture possesses strong antibacterial effect and good washing resistance. Its inhibition zone width against E. eoli and bactericidal rate are 1. 075cm and 100%. After 20 times washing, its inhibition zone width and bactericidal rate are 0. 780cm and 99.98%, resPectivelv.
