摘　　要：为构建适用于环锭数码纺混色纱的配色模型,以环锭数码纺纱机为平台,选用品红、黄色、青色、黑色、白色5种颜色的粗纱为原料,以10%为混纺梯度进行混色纺纱,并用小圆机织成针织物,进一步对织物进行测色。依据Kubelka-Munk双常数理论,用相对值法求解参数吸收系数和散射系数,并进行模型构建,结合全色谱算法和最小二乘法进行配色算法构建,实现对环锭数码纺混色纱的颜色预测与配方预测。用品红、黄色、青色3色粗纱按不同配比制备36种混色样进行预测效果分析。结果表明色差均值为1.74,平均比例误差为7.38%,色差分布小于2的占比达到72.22%,证明该模型对环锭数码纺纱系统具有适用性。With the aim to construct a color-matching model for ring digital spun yarns,the ring spinning machine is used to produce yarns from rovings of five colors(red,yellow,cyan,black and white)as raw materials,with a 10%blending gradient for color spinning.Such obtained yarns were then made in fabrics with a circular knitting machine to examine the color of fabrics.Based on the Kubelka-Munk double-constant theory,the relative value method was employed to solve the parameter absorption coefficient and the scattering coefficient,leading to the construction of the model.The color-matching algorithm was formulated by combining the full chromatogram algorithm and the least squares method to predict the color mixing in the ring digital spinning.Red,yellow and cyan rovings were prepared using different mixing ratios.The results showed that the average color difference was 1.74,and the average proportional error was 7.38%.72.22%of the samples demonstrated a color difference less than 2%,which proved that the model is applicable for the ring spinning system.
