Basic Dye is a stain that is cationic (positively charged) and so will react with material that is anionic (negatively charged). Their color base is not water soluble but can be made so by converting the base into a salt. The basic dyes, while possessing great tinctorial strength and brightness, are not generally light-fast. These are mainly applied to acrylic fibers, but find some use for wool and silk.
Basic Dyes are also known by name of cationic dyes and comprise class of synthetic dyes that works as base. Upon mixing in water, they assist in formation of colored cationic salt that react with anionic sites on surface of substrates. These basic dyes provide assistance in producing bright shades featuring superior tinctorial values on textile materials.Its application is similar to that of direct dyes but requires different and more precise controls with auxiliaries and temperature.
Basic Blue 9, also called methylene blue, is a type of very popular dye. It is stable in air, but it is sensitive to light. Basic Blue 9 is economical and it has excellent brightness.
