In the color report analyzed by the color difference meter, the color difference problem cannot be avoided by adjusting the equipment, process and formula in many cases, so at this time, the addition of suitable additives will be used to improve and adjust the color difference caused by factors such as cloth and equipment. . However, we know that additives are also auxiliary materials, which can sometimes solve one problem, but cannot fully solve all chromatic aberrations.
Only by re-selecting the auxiliaries with better effects on the basis of dyes and chemicals can we produce products that satisfy customers. There is a kind of fabric dyeing auxiliaries called anti-swimming agent. Generally, this kind of auxiliaries is used for dye migration caused by uneven drying temperature in wind room and drying, and improves the color difference caused by it. However, this kind of additive can't improve cotton impurities, neps, fabric surface defects, weaving defects, dead cotton, etc. The reason for this color difference is that the color of the cloth surface is uneven and not full, so the quality of the gray fabric is relatively poor. It is better to use leveling agent to improve this problem. However, there will be new problems when using leveling agent. The color difference is not easy to adjust. Compared with the use of anti-migration agent, the color difference will be more serious. In addition, the analysis results of the color difference meter show that multiple additives may be used at the same time, and the physical and chemical interactions between them will also lead to color difference.
Solutions to the color difference problem of fabrics:
Generally, when using additives, you can choose disperse black or disperse gray according to the gray color. The goal is to control the color difference at a certain level. Through mass production practice, use reasonable production technology and additives to solve the above difficulties. The data of the color difference meter used in production shows that the finishing additives should choose the additives that have little change in color light, because the greater the change, the greater the influence of conditions in production, and the unstable production process will affect the consistency of color light before and after.
Auxiliaries are used as a good product to improve the color difference of fabrics, but due to various physical and chemical factors, different auxiliaries have different effects after use. The mixing of various additives will also produce reactions, which requires the staff to use the color difference meter reasonably and experience joint control to solve the problem.
