| 摘 要： | 提出了一种以双常数理论为基础的求解涤、棉单色纤维的吸收系数和散射系数的方法——相对值法。根据单色纤维的吸收系数和散射系数对5个涤棉目标样进行反射率曲线拟合，拟合反射率曲线和仪器测量反射率曲线重合性较好，且计算得到的拟合色差在2．0（以CIEl976Lab为单位）以内。采用全光谱配色法对涤棉目标样进行了配方预测，实际混色样与计算出的预测配方之间的CIEl976Lab色差满足配色要求。

| Abstract: | In this paper, a relative value method that can solve absorption coefficients and scattering coefficients of each colored polyester and cotton fiber based on the two-constant theory is proposed. The absorption coefficients and scattering coefficients of each colored fiber are used to fit the reflectance curve of five polyester and cotton target blends, and good results are obtained. The algorithm of spectrophoto- metric color matching is run to predict the recipes for the five polyester and cotton target blends, and the color differences between the original target blends and the calculated ones are expressed in CIE1976Lab units. As a result, the color differences can meet color-matching requirements. |
