There are two main methods for coloring textile ribbon. One is the most widely used dyeing (conventional dyeing), mainly by placing the textile ribbon in a chemical dye solution. Another method is to use a coating to make the coating into tiny insoluble colored particles to adhere to the fabric (the fiber stock solution is not listed here).
Dyes are a relatively complex organic substance with many types.
1, acid dyes, more suitable for protein fiber and nylon fiber and silk. It is characterized by bright color, but poor water washing degree, excellent dry cleaning degree, and is widely used in natural dead dyeing.
2, cationic dyes (alkaline fuel), suitable for acrylic, polyester, nylon and fiber and protein fiber. It is characterized by bright color and is very suitable for man-made fibers, but it is used for washing and light fastness of natural cellulose and protein fabrics.
3, direct dye, suitable for cellulose fiber fabrics, washing fastness is poor, light resistance is not the same, but the modified direct dyes will have a good improvement in water wash color.
4, disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., washing fastness is different, polyester is better, viscose is poor.
5, azo fuel (nafto dye), suitable for cellulose fabrics, bright color, more suitable for bright color.
6, reactive dyes, mostly used in cellulose fiber fabrics, less for protein. It is characterized by bright color, light resistance, water washing and good friction resistance.
7. Sulfur dyes, suitable for cellulose fiber fabrics, with dark color, mainly navy, black and brown, excellent light and water wash resistance, poor chlorine bleaching resistance, long-term storage of fabric will destroy the fiber.
8, vat dyes, suitable for cellulose fiber fabrics, light, water washability, and resistant to chlorine bleach and other oxidative bleaching.
9, paint, suitable for all fibers, it is not a dye, but through the resin mechanical attachment fibers, dark fabric will become hard, but the color is very accurate, most of the light resistance is good, the water wash is good, especially in the middle, Light color.
