The webbing can be used as one of the clothing accessories or as one of the textiles. There are two main methods of coloring the webbing. One is the most widely used dyeing (conventional dyeing), mainly by placing the webbing 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). The following briefly introduces the dyeing process of the webbing.
Dyes are a relatively complex organic substance with many types.
1, acid dye: 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 the 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 dye its wash color will be very good.
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. Sulphur dye: suitable for cellulose fiber fabric, 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 fiber.
8, vat dye: suitable for cellulosic fiber fabric, light, water wash is very good, and resistant to chlorine bleach and other oxidative bleaching.
