The color and color of the dyed products are different,and there are two symptoms( in this problem):

One is batch chromatic aberration:In the same batch, there is a color difference between the case and the case, between the parts, between the bag and the bag, and between the piece and the piece.

The other also is batch chromatic aberration(but there's a difference):In the same batch of products, there is a color difference in the left or in the front and back, or in the front and back.

The fiber composition of all kinds of fabrics is different, the kinds of dyes and the process equipment used in dyeing are different, and there are different requirements and characteristics in dyeing and processing. The causes and manifestations of defects are different. Color aberration is varied in appearance, but the main reasons are as follows:

First is uneven distribution of dyes on fabric(including fabric factor,absorbent factor,pre-drying factor); Second is dyestuffs have a different degree of fixation on the fabric;Last is dye color variation(including predyed factors,dyeing factor,post-dye factors and soaping.)

The product has color difference that bring the bad shopping experience for consumer and the bad influence for brand public praise.Due to reduce this negative effect for minimum level,we should launch a strict test about color difference when the product is finished.
