Computer color-matching method of color-blended wool fabrics based on full-spectrum color matching

Abstract

The invention relates to a computer color-matching method of color-blended wool fabrics based on full-spectrum color matching, comprising the following steps of: (1) building a single-color reflectivity database; (2) primarily analyzing a sample; (3) selecting the reflectivity of single-color wool tops for carrying out color matching; (4) measuring the reflectivity of the sample; (5) carrying out full-spectrum color-matching calculation; and (6) correcting a formula by adopting a full-spectrum iteration correction method and finally realizing formula forecasting to color-mixing composition and proportion of the customer sample so as to achieve the aim of rapid color-matching. The invention has the advantages of high speed, high color-matching accuracy, simple and convenient operation, greatly-improved efficiency and potential merits.

Description

technical field [0001] The invention relates to a computer color matching method for color mixing of colored wool fibers, in particular to a computer color matching method for color mixing wool fabrics based on full-spectrum color matching. Background technique [0002] It is a production method commonly used by wool spinning enterprises to mix dyed monochrome wool fibers according to a certain mass ratio to produce various color melange fabrics. This production method can not only produce products with uniform color, but also produce products with non-uniform special effects, and during the production process, the carded loose fibers can still be used as raw materials for further carding, which is an environmentally friendly production method. For blending and color mixing (different colors, different fibers), since each component is dyed separately, a series of problems such as competition dyeing, staining, and damage to fibers due to dyeing can be avoided during the dyein...

Problems solved by technology

[0003] However, in the method of mixed-color wool fabrics, color matching is the first major difficulty. When color matching, the color matching personnel in the factory first untwist the yarns of the customer's samples, and then classify and weigh the fibers of the same color, and then rely on Color matching through experience and trial and error

Moreover, the computer color matching software widely used in dyeing formula prediction is not suitable for the color matching of mixed-color wool fabrics, and its production cycle is long and the production efficiency is low. Therefore, it is of great practical significance to study the computer color matching method of mixed-color wool fabrics
