What are the colors of denim?
Denim is a thicker yarn-dyed warp twill fabric. The warp yarn is dark in color, generally indigo blue, and the weft yarn is light in color, generally light gray or plain white yarn after scouring. Also known as indigo labor cloth.
There are mainly bromine indigo (commonly known as turquoise blue in the market) denim and vulcanized black denim. As well as coffee, emerald green, gray, khaki, and sulfur blue denim that use sulfur dyes to match colors. There are also a small amount of scarlet, pink, and royal denim dyed with naftor dyes or reactive dyes. Although the production volume is not large, the market demand is relatively urgent and often cannot meet the demand. The main problem is that the color and luster are not stable enough, and the dyeing value is also poor. The garment manufacturer is not satisfied. This is certainly related to the small production batch and too many colors. However, it is difficult to produce assorted varieties by dyeing and pulping combined machines, which are expensive, costly, and difficult to treat sewage, etc., which also have a certain impact.
The first solution is to minimize the number of colors in the design. Use two-color matching as much as possible, and no more than three-color matching at most. Or use other more stable dye varieties to replace. In order to adapt to the production characteristics of the dyeing and sizing online table, a more stable dyeing effect can be obtained. Second, the more thorough solution is to use yarn-dyed factories for large-capacity dyeing. The production process route of split warping is ideal to produce assorted denim.
