GENERAL INTRO TO BASIC DYES

Composition:
Basic dyes are salts of the colored organic bases containing amino and imino groups and also combined with a colorless acid, such as hydrochloric or sulfuric.

Application:
Basic green and other basic dyes are cationic which has positive electrical charge and are used for anionic fabrics which are negative-charge-bearing, such as wool, silk, nylon, and acrylics where bright dyeing is the prime consideration.

Advantage and Disadvantage
Basic green, yellow, violet, blue, red dyes are brilliant and most fluorescent among all synthetic dyes. They are ideal for bright color fabric dyeing, but they have poor light fastness and wash fastness.
