摘　　要：为了提高原液着色涤/黏双组分混配色打样效率,基于Kubelka-Munk双常数理论模型,选用3种单色(大红、宝兰G、金黄)涤纶短纤维和3种单色(大红、蓝色、黄色)黏胶短纤维为研究对象,以6种单色纤维进行双组分混色,按9种不同混合比例共得到54种三色混色双组分纤维样品。利用测色仪测定混色样的颜色特征参数:反射率(R)、颜色深度(K/S)、明亮度(L)、红绿色度(a)及黄蓝色度(b),利用最小二乘法对数据进行处理;最后对计算混色比例与实际混色比例之间的误差进行评价,以验证Kubelka-Munk双常数理论模型在双组分混配色中的适用性。结果表明,54种样品的色差均在1.0以下,均值为0.2775,标准差为0.2177,预测比例与实际比例差距较小,红色涤纶与蓝色、黄色黏胶组合的平均比例误差最小,为1.109%,说明其比例预测效果较好,而黄色涤纶与红色、蓝色黏胶组合的平均色差最小,为0.1721,说明其颜色预测较好。In order to improve the efficiency of the color matching of the two components of the pigment polyester/viscose,based on Kubelka-Munk double constant theoretical model,three monochrome(bright red,royalblue G,golden yellow)polyester staple fiber and three monochrome(bright red,blue,yellow)viscose staple fiber were selected as the research objects,twocomponent fibers color mixing was carried out with 6 monochromatic fibers,according to 9 different mixing ratios,54 kinds of three-color mixed-color two-component fiber samples were obtained.The color characteristic parameters,such as reflectance(R),color depth(K/S),brightness(L),red green chromaticity(a)and yellow blue chromaticity(b),were measured by spectrophotometer,the least square method was used to process the data.Finally,the error between the calculated color mixing ratio and the actual color mixing ratio was evaluated.The applicability of Kubelka-Munk two-constant theory model in two-component color mixing was verified.The results show that the color differences of 54 samples are all below 1.0,the mean is 0.2775 and the standard deviation is 0.2177,the differences between the predicted ratio and the actual ratio are small,the average ratio error of the combination of red polyester with blue and yellow viscose is the smallest,1.109%,indicating that the ratio prediction effect is good.The average color difference of the combination of yellow polyester with red and blue adhesive is the smallest,which is 0.1721,indicating that the color prediction is good.
