Abstract:

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.

Key words: color spinning, spectral reflectivity, computer color matching, color correction algorithm, color difference
