Main characteristics of chromatic aberration of the dyeing and finishing, dyeing products prepared with different shades of color, the color difference, mainly reflected in: 1, the same batch of color, the same batch of products, a color carton and box, from piece to piece, and between packages, horse and horse color shading between; 2, the same horse color: with horse centre, left and right of a color or before and after the positive and negative have color or color.
Cause of production

Wooshi Zipper

All kinds of woven fabric with different composition and dyeing the dye types and different process equipment, and dyeing processing have different requirements and characteristics, the reasons for defects and performance is not the same. Color diversity in appearance, but the reason, mainly to several:

1, Dyes in the fabric prior distribution is not uniform: dye before fixation, if in weaving the parts on the uneven distribution, solid color must cause the color difference, causing the main reason for this phenomenon is:

A Fabric factors: due to the different fiber properties or pre-treatment is not uniform enough to make the first half of the dye penetration of the dye caused by the differences in the degree of dye absorption.

B Absorption factors: due to reasons or misoperation mechanical structure, fabric in all parts of the liquid at the same rate, resulting in color. Roller pressure unevenness, unevenness of dye of adding would make the fabric absorbing dye unevenness.

C Pre drying factors: in pad dyeing after pre drying, due to the inconsistency of the rate and extent of drying, causing dye has different degree of migration to make dyes in fabric are unevenly distributed.
