Textile coloring There are two main methods, one of the most widely used staining (conventional staining), mainly in the textile processing chemical dye solution. Another method is to use paint, the paint is made of tiny colored particles insoluble in the adhesive and fabric (dope dyed fiber materials not included). Dye is a complex organic substances, many of its kind.
　　1, acid dyes, more suitable for protein fibers such as silk and nylon fibers. It characterized by bright color, but the water of the poor, excellent dry degree, the use of natural death in the more extensive staining.
　　2, cationic dyes (basic fuel) for acrylic, polyester, nylon and fiber and protein fibers. Which is characterized by bright color, it is suitable for man-made fibers, but washing and light shading for natural cellulose and protein fabric is poor.
　　3, direct dyes suitable for cellulose fiber fabric, relatively poor wash fastness, fastness to light varies, but is modified to direct dyes its water color will be a very good improvement.
　　4, disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., wash fastness varies, preferably polyester, viscose poor.
　　5, azo fuel (naf dye), suitable for cellulosic fabric, bright color, more suitable for bright color.
　　6, reactive dyes, mostly used for a cellulose fiber fabric, less for the protein. Is characterized by bright color, light, washing, rubbing is better.
　　7, sulfur dyes suitable for cellulose fiber fabric, color gray, mainly dark blue, black and brown, light, washable degree excellent resistance to chlorine bleaching poor, long-term storage will destroy the fabric fibers.
　　8, vat dyes for cellulose fiber fabric, light, washing of the well, and resistant to chlorine bleach and other oxidizing bleach.
　　9, paint, suitable for all fibers, it is not a dye, but through the resin mechanical attachment fiber, dark fabric will harden, but very accurate chromatic, most good fastness to light, washing of good, especially in light.
