防紫外线织物(二)

UV-Cut Processed Fabric (Ⅱ)

3 加工技术 主要采用各种方法将紫外吸收剂和陶瓷或金属氧化物(粉末或分散液)分别或共同对纤维和织物进行处理,并能牢固结合。加工方式有纺丝法、后整理法和涂层法。 3.1 纺丝法 选用适当的紫外吸收剂以及陶瓷细粉或金属氧化物与纤维共同纺丝,制成紫外屏蔽纤维。紫外吸收剂必须与纤维有较好的相容性;要求仿丝工艺不使添加剂起分解、升华等不良影响;陶瓷细粉或金属氧化物有较高细度,符合纺丝工艺要求。有时这两者同时加入。

The current situation of anti-ultraviolet fabric was analysed. In this article,the author recommented the performance of UV-absorber and UV-reflectance agent and their application,summarized the processing technology. Based on the combination of current situation with domestic condition ,the author put forward the exploration and research in future from the protective agent, processing technology ,end-products and testing method.
