Analysis of the effect of water washing and printing after printing
Washing is closely related to the quality of printed products, which directly affects the hand feel, luster, whiteness, brightness and fastness of fabrics. For example, the silk fabric itself has a soft, smooth feel and a certain gloss. After printing and steaming, if the paste attached to it is not washed clean in the washing process, it will make the finished product feel rough and hard, and lose the luster that silk should have; if the floating color is not washed clean, it will reduce the color fastness of the finished product; under the condition of small water tank capacity and slow water exchange speed, dark color printing Because of the increasing concentration of dyes and auxiliaries in the water, fabrics tend to be stained white and light, which makes the color of the pattern fade. Therefore, choosing good washing conditions is one of the keys to improve the printing quality.
