k]Immobilizing inorganic particles such as zinc oxide (ZnO), titanium dioxide (TiO₂), silver nanoparticles (Ag NPs) or grafting special biopolymer such as chitosan on cotton fabrics is the main method to prepare antibacterial and ultraviolet (UV) protective cotton fabrics. However, poor durability and complex finishing methods are still of the main defects of antibacterial and UV protective fabric samples. In the present work, the Ag/TiO₂ colloid solution was prepared with using the carboxymethyl chitosan (CMC) as a stabilizer, then the CMC and Ag/TiO₂ composite nanoparticles were coated on the fabric via finishing technology of pad-dry-cure. As a result, the modified fabric showed excellent antibacterial and UV protective properties, with the values of bacterial reduction (BR) and ultraviolet protection factor were reached at 99.5 % and 79.0, respectively. Moreover, even after 50 washing cycles, these properties of the finished fabrics were not obviously reduced. These results demonstrated that the finished fabric sample has durable antibacterial and UV protective properties which could has a great potential application in the field of medical and outdoor apparel.

k]在棉织物上固定氧化锌（ZnO）、二氧化钛（TiO ₂）、银纳米粒子（Ag NPs）等无机颗粒或接枝壳聚糖等特殊生物聚合物是制备抗菌防紫外线（UV）防护棉的主要方法面料。然而，耐用性差和整理方法复杂仍然是抗菌和防紫外线织物样品的主要缺陷。在目前的工作中，以羧甲基壳聚糖（CMC）为稳定剂，然后用羧甲基壳聚糖（CMC）和Ag/TiO ₂制备了Ag/TiO ₂胶体溶液。通过轧干固化整理技术将复合纳米粒子涂覆在织物上。结果，改性织物表现出优异的抗菌和紫外线防护性能，细菌减少（BR）值和紫外线防护系数值分别达到 99.5% 和 79.0。此外，即使经过 50 次洗涤循环，整理后织物的这些性能也没有明显降低。这些结果表明，成品织物样品具有持久的抗菌和紫外线防护性能，在医疗和户外服装领域具有巨大的应用潜力。
