Why is the color of the front of the coral blanket dark and the color of the back light?

This depends on the process and cost reasons, and some are divided into pros and cons.
Coral fleece fabrics are mainly divided into two categories, namely: A and B double-sided coral fleece, A and B single-sided coral fleece; among them, as far as single-sided coral fleece is concerned, A-side coral fleece is better than B-side coral fleece. Because the weaving methods of coral fleece on side A and coral fleece on side B are different, coral fleece on side A belongs to the front weaving of the loom, while side B is the reverse side. Because when cutting the width, only the hair height on the front side is ignored, and whether the hair height on the back side is neat or not, resulting in certain differences in the woven gray fabrics.
Because A and B double-sided coral fleece are more expensive than single-sided coral fleece gray fabrics, in the whole process, double-sided coral fleece has one more important process than single-sided coral fleece - napping. Double-sided coral fleece needs to be brushed to achieve the effect of fluff on the reverse side, while single-sided coral fleece does not need to be brushed, so there is a big gap between the two processing costs. Generally, the processing cost of double-sided coral fleece is higher than that of single-sided coral fleece. Coral fleece is 70% higher.
