摘要
阐述了紫外线各波段对人体的危害以及遮阳伞防紫外性能的原理,重点讨论了伞面织物的种类、颜色、结构、防紫外线整理方式以及气候状态等因素对遮阳伞防紫外线性能的影响。结果表明,伞面织物颜色较深、结构紧密的遮阳伞防晒效果较好。双面银胶或黑胶涂层整理的遮阳伞比普通银胶的防晒效果好且涂层最好在伞面内侧。长期暴晒雨淋等气候状态会减弱遮阳伞的防紫外性能。
In the paper are described the human body injured by certain wave range of UV,and the principle of sunshade ultraviolet prevention performance.The focus of discussion is on the effect of fabric fiber,fabric color,fabric structure,the way of fabric finishing on UV prtection and climate state.The result shows that fabric deeper color, compact structure can gain better anti-UV performance. The sunshade with double sided silver glue or vinyl is better than ordinary silver glue and the coating in the inside of sunshade is better. The exposure to the sun and rain for a long time will weaken the sunshade ultraviolet prevention performance.
