摘　　要：为提高色纺企业配色打样效率和配色效果,以Friele光学模型为基础,结合全光谱匹配配色算法,以某色纺企业的实际生产为例探讨色纺纱的计算机修色算法。首先随机确定21个混色标准样,分别从现有的80种单色棉纤维中选择2~4种计算拟合配比并打样,测得21组样纱的实际色差均值为2.36。将拟合配比进行赋值循环以计算标准样与仿样的反射率偏差最小时的配比调整量,用以修正拟合配比,并再次打样验证。结果表明:拟合配比第1次修正后实际色差均值为1.215,其中最小色差为0.59;经第2次配比修正后,实际仿样与标准样的色差均值减小到0.67,且每组色差均小于1,即所设计的修色算法精确度较高,且适用于企业实际生产。This wor was carried out aiming to improve the color matching and proofing efficiency in color spinning.Based on the Friele optical model combined with the full spectrum matching color matching algorithm,which was applied in the actual production of a color spinning enterprise,the corresponding color correction algorithm was designed.Twenty-one standard samples were randomly determined,and 2-4 types of matching ratios were calculated and sampled from the existing 80 types of single-color cotton fibers.The average color difference of the 21 groups of samples was 2.36.The research results show that the average color difference of the fitting ratio is 1.215 after the first correction,in which the minimum color difference is 0.59;after the second correction of the ratio,the average color difference between the actual spinning samples and the standard samples drop to 0.67,and the color difference of each group is less than 1.It demonstrated that the designed color correction algorithm,which has high accuracy,is applicable for actual production.
