摘要纺织品的色彩性能受多种因素的影响。为了使颜色呈现得更加精确，有必要明确织物结构与染色效果的关系，以便在配色时根据不同织物对所显示的颜色进行补偿。采用还原染料对不同的棉织物进行轧染，并采用主成分分析法对织物的综合性能进行分析。根据因素权重，得出影响染色效果的主要因素，建立了织物性能综合值与染色效果的数学回归模型。结果表明，随着染料浓度的增加，织物的表观色光深度相应增加。对于相同染料浓度的不同织物，其表观色光深度随织物结构的不同而不同。影响织物染色效果的主要因素有光泽度、白度、纬密、粗糙度、克重5个。织物性能综合值与染色后的K/S值呈负相关。织物综合值越小，染色后的表观颜色越深。
Abstract Color performance on textiles is affected by many factors. In order to make the color presented more precisely, it is necessary to clarify the relationship between fabric structure and dyeing effect, so as to compensate the color displayed according to different fabrics in color matching. Pad dyeing of different cotton fabrics with vat dyes was carried out, and principal component analysis was used to analyze the comprehensive properties of fabrics. According to the factor weight, the main factors affecting the dyeing effect were obtained, and a mathematical regression model between the comprehensive values of fabric properties and the dyeing effect was established. The results showed that with the increase of dye concentration, the apparent shade depth of the fabric increased correspondingly. For different fabrics with the same dye concentration, their apparent shade depth varied with the fabric structure. There were five main factors affecting the dyeing effect of fabrics, which was glossiness, whiteness, weft density, roughness, gram weight. The comprehensive values of fabric properties were negatively correlated with the K/S values after dyeing. The smaller the comprehensive value of fabric, the deeper the apparent color after dyeing.
