There are two main methods of coloring textiles, one is the most widely used dyeing (conventional dyeing), mainly to the textile in the chemical dye solution, another method is the use of paint, the paint made of small insoluble colored particles to adhere to the fabric (fiber raw materials dyeing and not the original).

Dye is a kind of complex organic matter, it has many kinds.

1, acid dyes, more suitable for protein fiber and nylon fiber and silk and so on.

Its characteristics are bright color, but poor washing fastness, dry cleaning fastness, the use of natural death in a wide range of dyeing. 

2, cationic dyes (alkaline fuel), suitable for acrylic, polyester, nylon and cellulose and protein fiber.Its characteristics are bright color, very suitable for man-made fibers, but used for natural fiber and protein fabric washing and light fastness is poor.

3, direct dyes, suitable for cellulose fiber fabric, washing fastness is poor, light fastness is different, but the modified direct dye its washing color fastness will be very good improvement.

4, disperse dyes, suitable for viscose, acrylic, nylon, polyester and so on, washing fastness, polyester better, viscose poor.

5, Azo fuel (nerf dye), suitable for cellulose fabrics, bright color, more suitable for the gorgeous color. 6, reactive dyes, mostly used in cellulose fiber fabric, less for protein.

It is characterized by bright color, light resistance, washing, and good rubbing fastness.

7, sulfur dyes, suitable for cellulose fiber fabric, color gray, mainly with navy, black and brown, light, washable fastness excellent, chlorine-resistant bleaching fastness, long-term storage fabric will destroy fiber.

8, reducing dyes, suitable for cellulose fiber fabric, light, washing fastness is good, and chlorine bleaching and other oxidation bleaching.

9, coating, suitable for all fibers, it is not a dye, but through the resin machinery attached fibers, dark fabric will harden, but the color is very accurate, most of the light fastness, good washing fastness, especially in the light.
