This part is review some fundamentals of technologies, its broad application, and gathering some new researches and studies regarding technological aspects in the extraction of natural dyes and there dyeing process on cellulosic fibers. It focuses on recent developments in the coloration of cellulosic fibers. New technique has been involved in the application of the natural dyes such as Ultrasonic, Microwave, Enzymes treatment, Ultraviolet Radiation (UV) Technology, chitosan and plasma that have the potential to limit the environmental impact and now become accessible due to less use of energy, water as well as a chemical to compare with the conventional methods.
