What are the reasons for the color difference (cylinder difference, bar difference) caused by additive color?

A. The feeding speed is different. If the dose of dye is added is small, it will affect whether it is added in batches, such as one-time addition, the time is short, and the dyeing is not sufficient, resulting in color discoloration.

B. The rubbing on both sides of the feed is uneven, causing stripe deviation, such as one side with more dark color and less side with lighter.

C. Holding time

D. Different color techniques of cut samples cause chromatic aberration. Requirement: Cut samples in the same way to match colors.

For example, the color of the cut sample after the heat preservation is 20, and the degree of washing after the cut sample is different.

E. Different sizes of bath ratios cause chromatic aberration. Small bath ratio: deep color Large bath ratio: light color

F. The degree of post-processing is different. Adequate post-processing, adequate removal of floating color, lighter color than insufficient post-processing.

G. There is a temperature difference between the two sides, resulting in a gap

Add color slowly, at least 20 minutes of quantitative injection, and 30-40 minutes for sensitive colors.
