Carding object of color spinning (1)

  1. Colored fibers

Colored spinning uses two or more different colors of fibers, so combing is not only natural color fibers, but also colored fibers, such as dyed cotton fibers or colored chemical fibers.

The properties of non-ferrous fibers are different from those of non-ferrous fibers. Take the most commonly used and most used dyed cotton fiber as an example, the dyeing process of cotton fibers needs to undergo acid, alkali, high temperature and other effects. While obtaining color, the fibers are corroded and destroyed, and wax, fat, gum, protein, sugar and other substances are removed or reduced. The color elements and auxiliary substances are intervened chemically or physically, and the degree of polymerization of the damaged fibers is decreased, the strength loss, and the short piles are increased. It can be seen that the fiber spinnability is degraded.

The spinnability of chemical fibers after dyeing usually decreases, and the properties of chemical fibers dyed by source solution are different from those of natural fibers (such as material density, surface friction properties, etc.).

The spinnability of non-ferrous fibers is different from that of non-ferrous fibers. The carding process during spinning needs to be strained.

 

  1. Mixed fibers

Usually, the natural color spinning is to comb different kinds of fibers (such as cotton and polyester) separately into strips, and then merge them into the back treatment. Colored spinning is different. In order to ensure uniform blending, different colored fibers have been mixed before carding, so when carding fibers, it is often necessary to face different mixtures.

Natural color spinning combs different fiber materials separately, and different carding processes can be adopted, but this method is not suitable for mixed fibers of different properties faced by colour spinning.
