There are four types of fabric dyeing using environmentally friendly direct dyes: 1. Fiber dyeing-dyeing is done when it is still fiber. Such as: flower gray;

Cellulose fiber dyeing, the process of dyeing cotton, hemp, viscose and cupra fiber textiles. Cotton and hemp fiber textiles should be fully removed from the cellulose symbiotic before dyeing. When dyeing textiles of cuproammonium or viscose fiber, tension and friction should be reduced as much as possible to prevent deformation or generation of hairs that affect the quality of the dyed products.

2. Yarn dyeing-dyeing is done after spinning into yarn. Such as: plaid shirt; yarn dyeing is done by spinning the grey yarn first and then dyeing. It can't be used for fancy color, only plain color. The color is easy to dye flowers, and the fabric feels better than loose dyeing. 3. Piece dyeing-dyeing is done after weaving into cloth. Such as: pure color clothes; This is the corresponding yarn-dyed fabric. Yarn-dyed fabric is first dyed with yarn, then weave, and finally finished, the finished product is produced. The piece dyeing textile factory comes out of the original color grey fabric, throws it into the dyeing vat for dyeing (or long-car pad dyeing), and then finishing, and finally the finished product. Piece dyeing can be one piece of cloth, or several pieces of cloth in a row, suitable for small orders of fashion; it can also be dyed in large quantities, suitable for large orders in the market. 4. Piece dyeing-dyeing into pieces after making clothes. The effect is better, the hand feels very soft and smooth, and it is more durable.
