Textile ribbon coloring there are two main methods, one is the most widely used dyeing (conventional dyeing), mainly in the textile ribbon in chemical dye solution treatment. Another method is to use paints, which are made into tiny, insoluble colored particles that adhere to the fabric (except for dyeing the raw material).Dye is a kind of complex organic matter, and there are many kinds of it.
1, acid dyes, more suitable for protein fiber and nylon fiber and silk, etc. It is characterized by bright color, poor washing degree and excellent dry cleaning degree. It is widely used in natural dying dyeing.
2, cationic dye (alkaline fuel), suitable for acrylic fiber, polyester fiber, polyamide fiber and protein fiber. It is characterized by bright color, very suitable for artificial fiber, but used for natural cellulose and protein fabric washing and light resistance is very poor.
3, direct dye, suitable for cellulose fiber fabrics, washing fastness is poor, light resistance is not the same, but the modified direct dye washing chroma will be very good improvement.
4, disperse dyes, suitable for viscose, acrylic fiber, nylon, polyester, etc., washing fastness is different, polyester is better, viscose is worse.
5, azo fuel (naftol dye), suitable for cellulose fabrics, bright color, more suitable for bright color.
6, reactive dyes, mostly used for cellulose fiber fabrics, less used for protein. It is characterized by bright color, light resistance, washing and good friction resistance.
7, vulcanized dyes, suitable for cellulose fiber fabrics, dark color, mainly dark blue, black and brown, light resistance, water resistance is excellent, chlorine bleaching resistance is poor, long-term storage fabric will destroy fiber.
8, VAT dyes, suitable for cellulose fiber fabrics, light resistance, washing is very good, and resistance to chlorine bleaching and other oxidation bleaching.
9, coating, suitable for all fiber, it is not a dye, but through the resin mechanical adhesion fiber, dark fabric will harden, but the color is very accurate, most of the light resistance is good, good washing, especially medium and light color.-term storage fabric will destroy fiber.
