摘　　要：织物的防紫外线研究大多在整理剂和整理工艺,而在织物的颜色对于防紫外线性能的研究方面相对薄弱。文章选择了真丝(蛋白质纤维)织物,通过数码印花的方式利用活性染料染得HSV模式下的试验样品色块。测试了在UVA和UVB波段各色块的紫外线屏蔽率,探讨在颜色模式HSV下,色相、明度、饱和度对真丝织物防紫外性能的影响规律。研究表明:色相为9、54、108、234及270时,紫外线屏蔽率高;色彩明度越低,紫外线屏蔽率越高;色彩饱和度越高,紫外线屏蔽率越高。Anti-UV researches on fabrics mostly focus on finishing agents and finishing processes, while the research on UV-resistant performance of fabric color is relatively weak. The silk （protein fiber） fabric was selected in this paper, and testing samples of HSV color mode were digitally printed by reactive dyes. The UV shielding ratios of UVA and UVB bands were tested, and the influence of color factors, such as hue, brightness and saturation, on the anti-UV performance of the fabric was investigated. The results show that anti-UV performance is high when the hue value of color is 9,54,108,234 and 270. The lower the brightness value is, the higher the anti-UV performance is. The higher the saturation value is, the higher the anti-UV performance is.
