DYES

Pigment Dyes

Pigment is a substrate in a particulate form which is insoluble in water but which can be dispersed in this medium to modify its color and light scattering properties. They are organic or inorganic coloring materials. They have no affinity to textile materials. They are fixed on the textile material with the help of binding agent in form a thin invisible coating.

Acid Dyes

An acid dye is a dye that is typically applied to a textile at low pH. They are mainly used to dye wool, not cotton fabrics.

Based on dyeing characteristics (wool dyeing) acid dye can be classified as:

Levelling acid dye
Fast acid dye
Milling acid dye
Super milling acid dye

Reactive Dyes

Reactive dye is a class of dye that makes a covalent bond with the fiber and becomes an integral part of the fiber. These are usually used to dye cellulosic fibers such as cotton, rayon, or flax, but polyamide, wool, silk, and acetate fibers can also be dyed using reactive dyes.

Direct Dyes

Direct dye, also called Substantive Dye, any of a class of coloured, water-soluble compounds that have an affinity for fiber and are taken up directly, such as the benzidine derivatives. Direct dyes are usually cheap and easily applied, and they can yield bright colours.

Acrylic Dyes

Acrylic (Cationic) Dyes are specially developed for dyeing Acrylic Fiber which is widely used in the manufacturing of Blankets, Carpets, Knitting Goods, Decorative Fabrics, Fur Toys, Dress Materials, Sarees, etc. They are water soluble mainly applied to acrylic fibers, but some use for wool and silk.

Disperse Dyes

Disperse dye is a category of synthetic dye intended for polyester and related hydrophobic fibers. Disperse dyes are polar molecules containing anthraquinone or azo groups. It is estimated that 85% of disperse dyes are azos or anthraquinone dyes.
