Get strong and brilliant color shades with basic dyes

Basic dye is a class of synthetic colorants. The unique feature of these coloring agents is that they are water insoluble. Water-soluble salts are added to these color bases to produce brilliant colors with high tinctorial values on textiles.

These dyes produce colors by reacting with material that is anionic or negatively charged. They are also called cationic dyes because the positively charged part (called cationic) of the salt is responsible to produce shades.

Basic dyes are suitable for acrylic fibers and jute. The reason is that light fastness on such materials is excellent. Besides, they can also be used to color natural fibers such as like silk, cotton, wool etc. It is important to inform you that by this colorant do not form strong bond to cotton and more likely to fade when exposed to light.

In order to produce light fatness shades the dyeing material need to be passed through a special treatment called mordanting. In this process, a substance called mortdant is added to form strong coordination with dye.

Properties of basic coloring agents are moderate substantivity, great Tinctorial strength, number of different shades, and color brightness. Moreover, they are economic than other coloring agents. With significant advancements in chemical science, basic colorants are modified to produce better light fastness for all kinds of fibers with excellent substantivity.
