Embodiment Construction
[0071] Concrete steps of the present invention are as follows:
[0072] (1) Calculate the initial formula by using the full-spectrum color matching algorithm according to the target color spectrum data;
[0073] Obtain target color by spectrophotometer color measurement The wavelength range is 400-700nm, the interval is 10nm, a total of 31 data, see Table 1, the material is cotton fiber, and the yarn specification is 30;
[0074] Select monochrome from the database to color ( Input after testing in advance, see Table 1), i is a natural number, representing different monochromatic fibers, the more monochromatic fibers are selected, the more formulas that meet the requirements will be, and the more difficult the empirical screening is.
[0075] Table 1 The target color measured by the spectrum and the reflectance data of the single-color fiber in the database
[0076]

The invention relates to a formula screening and correction method for spun-dyed yarn color matching. When the color matching is carried out on the spun-dyed yarn by using a computer, formulas are too much, formula deviation is poor, one-time color matching accuracy is low; and manual experience correction is needed. The formula screening and correction method comprises the following steps of (1) calculating an initial formula by adopting an all-spectrum color matching algorithm according to target color spectroscopic data; (2) conducting formula screening by using a constructed spun-dyed yarn formula estimation module; (3) drawing a design for the screened optimal formula, calculating aberration between a simulated sample and a target color, on yes judgment, outputting the formula, and on no judgment, entering formula correction; and (4) correcting on the basis of the original formula by adopting a constructed spun-dyed yarn formula correction module, simulating a sample after obtaining a corrected formula until the formula meets requirements. The formula screening and correction method solves the problem that the formulas are too much and difficult to screen and the experience correction is needed and the like when the color matching is carried out on the spun-dyed yarn by using the computer, and greatly improves color matching efficiency.
Description
technical field [0001] The invention relates to an auxiliary method for computer color matching of color spinning yarns, in particular to a method for providing formula optimization and formula secondary correction during color spinning computer color matching. Background technique [0002] In colored spinning, two or more fibers of different colors are fully mixed and then spun into a yarn with a unique color mixing effect. In recent years, the proportion of this mixed-color spinning processing method in the wool, cotton and chemical fiber fields is increasing year by year. [0003] In the wool spinning industry, the production of worsted and woolen fabrics and sweaters basically adopts top dyeing and loose wool dyeing. After combing tops, loose wool and wool processes, mixing colors or synthesizing colored yarns, multi-color fibers and even multi-groups are produced. The composite wool yarn not only ensures the same color of the same batch of products, but also produces h...
