锦纶织物超细TiO_2防紫外线与抗老化涂层整理
|
摘要
超细粉体通常具有一系列特殊的物理化学性质,如防紫外线、抗老化等性能。文中研究了超细TiO_2分散体系稳定性影响因素,并将超细TiO_2对锦纶织物进行涂层整理,测试分析了TiO_2涂层整理后织物的防紫外性能和抗老化性能。结果表明,采用水性聚氨酯涂层胶掺杂超细TiO_2粉体材料的处理工艺能有效提升常规锦纶66的防紫外线和抗老化性能,整理后锦纶织物的紫外线透过率降低,强力损失由原来的46.2%升高到35.8%。
Ultrafine powder has a series of special physical and chemical properties, such as anti-ultraviolet and anti-aging. This paper studied the effects on ultrafine TiO_2 decentralized system stability and superfine TiO_2 was used to coat nylon fabric. It tested and analyzed the anti-ultraviolet performance and anti-aging properties of the coated fabrics by ultrafine TiO_2. The results show that the PU water-based coating together with the ultrafine TiO_2 powder materials could effectively improve the anti-ultraviolet performance and anti-aging capacity of conventional nylon 66 fibers. The ultraviolet transmittance of the coated nylon 66 fabrics decreased and the strength loss increased from 46.2% to 35.8%.
