This paper reports the studies available on the textile materials such as cotton, wool, and silk, etc. dyeing of natural dyes; extraction of colorants from different natural plant sources; effects of different mordants and mordanting methods; effect of dyeing time, temperature, and dye concentration; PH of the dye bath conventional and nonconventional methods of plant natural dyeing; Use of analytical instruments; Thermodynamic parameters and kinetics of dyeing; and dyeing of compatibility for application of binary, and a ternary mixture of plant natural dyes. Attempts for improvement in overall color fastness properties have been discussed.
