Knowledge of textile dyes

Common textile dyes are introduced

1, acid dyes, more suitable for protein fiber, nylon fiber and silk. It is characterized by bright color, poor washing fastness and excellent dry cleaning fastness, which are widely used in natural fiber dyeing.

Cationic dyes (basic dyes), suitable for acrylic, polyester, polyamide, cellulose and protein fibers. It is characterized by bright color and is suitable for man-made fiber, but it is not good for washing and light fastness of natural cellulose and protein fiber fabric.

3. Direct dyes, suitable for cellulose fabrics, have poor washing fastness and different light fastness. However, the washing color fastness of modified direct dyes can be well improved.

4, disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., washing fastness is different, polyester is good, viscose is bad.

5, azo dyes (naftod dyes), suitable for cellulose fiber fabrics, bright color, more suitable for bright color.

6, reactive dyes, mostly used for cellulose fabrics, less used for protein. It is characterized by bright color, light resistance, good fastness to washing and rubbing.

7, sulfur dyes, suitable for cellulose fabrics, dark color, mainly navy blue, black and brown, light resistance, water resistance is very good, chlorine bleaching resistance is poor, long-term storage fabric will damage the fiber.

8, VAT dyes, suitable for cellulose fabrics, good fastness to light, washing, chlorine bleaching and other oxidation bleaching.

9, paint, suitable for all fibers, 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 fastness to light, good washing fastness, especially medium and light color.
