Dyeing Process of Ribbon

【Industry news】 Date:2023-03-20
Ribbon can be used as one of the clothing accessories, as well as one of the textiles. There are two main methods for dyeing webbing. One is to use Z as a broad range of dyeing (conventional dyeing), mainly by placing the webbing in a chemical dye solution for treatment. Another method is to use paint, which is made into tiny insoluble colored particles to adhere to the fabric (fiber raw material stock dyeing is not included). The following is a brief introduction to the dyeing process of webbing.

Dyes are a relatively complex organic substance with many types.

1. Acid dyes are widely used in protein fibers, nylon fibers, and real silk. It is characterized by bright color, but poor water washability and excellent dry cleaning, and is widely used in natural dead dyeing.

2. Cationic dyes (alkaline fuels) are suitable for acrylic, polyester, nylon, fiber, and protein fibers. Its characteristic is bright color, which is very suitable for man-made fibers, but it is used for washing natural cellulose and protein fabrics with poor light fastness and color fastness.

3. Direct dyes are suitable for cellulose fiber fabrics, with poor washing fastness and varying light fastness. However, modified direct dyes can significantly improve their washing color.

4. Disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., with different washing fastness, better polyester, and worse viscose.

5. Azo fuel (Nafto dye), suitable for cellulose fabrics, with bright colors, more suitable for bright colors.

6. Reactive dyes are mostly used in cellulosic fabrics, but less in proteins. It is characterized by bright color, light resistance, water washing, and good friction resistance.

7. Sulfide dyes are suitable for cellulose fiber fabrics. They have a dull color, mainly in navy, black, and brown. They have excellent light and water resistance, and poor resistance to chlorine bleaching. Long term storage of fabrics can damage fibers.

8. Vat dyes, suitable for cellulose fiber fabrics, have excellent light resistance, water washability, and resistance to chlorine bleaching and other oxidative bleaching.
