For the development of dyed spinning and dyed spinning products, if the fibers of various colors are unevenly mixed, after being made into yarn and cloth, the surface of the fabric is not a three-dimensional, subtle, hazy color style, but the color difference between the pieces and the horizontal, which is the defective yarn and waste cloth.
In fact, natural color spinning also has color mixing technology, which is the mixing function of cleaning, combing, merging and fine processes. Although the raw materials of each mark are white, the color will be slightly different, Xinjiang cotton is white, and the cotton in the interior and coastal areas is relatively yellow, and it can be dissolved into one color by blending. However, in the season when the new cotton is on the market, if the cotton is slightly improper, yellow and white yarn will be produced, because the yellow and white difference between new cotton and old cotton is a little bigger, which shows that the mixing function of the general spinning process is limited.
The color difference of the color spinning raw materials is much greater than that of the natural color spinning. For example, the most common hemp gray yarn is a blend of black cotton and white cotton, which is the difference between black and white, compared with the yellow and white difference between old cotton and new cotton, it is much larger, and the general blending technology must not meet the needs of color spinning.
