交织方式对光致变色织物变色效果的影响

Influence of Interweave Style on Color Change Effect of Photochromic Fabric

探讨交织方式对光致变色织物变色效果的影响。以变色粘胶长丝及普通粘胶长丝为纬纱,织造了3种纬纱配比的平纹织物,测试了织物变色前后的有关颜色指标,包括三刺激值、颜色空间、彩度、光泽度、K/S值、光谱反射率等;通过一元方差分析了各项指标与织物变色效果之间的显著性。结果表明:不同的纬纱交织方式对织物色相、明度、彩度影响十分显著,对光泽度和K/S值影响不显著。认为:通过合理设定纬纱配比,可以设计出不同的光致变色织物。

The influence of weave pattern on color change effect of photochromic fabric was discussed. Color changing viscose filament and normal viscose filament were used as weft. The plain weave fabrics with three kinds of weft yarn ratios were woven. The related color indexes of fabric before and after color change including tristim- ulus value, color space, saturation, glossiness, K/S value, spectral reflectivity and so on were tested. The signifi- cance between each index with the fabric color change effect was analyzed with univariate analysis of variance. The test results show that the influences of different weft weave patterns on fabric hue, lightness and saturation is ob- vious while the influence on glossiness and K/S value is not obvious. It is considered that different photochromic fabrics can be designed by reasonable setting weft ratios.
