Population, economic growth, and industrialization in the world cause an increase in the amount of waste. Waste policies should be developed, and waste management studies should be carried out, especially in the environment causing landfill problems. Recycled polyethylene terephthalate (r PET) is the widely recycled plastic employed for new textile production in the world. It reduces environmental impact and lowers cost of the production. For the traditional dyeing of polyethylene terephthalate (PET), commercial disperse dyes are generally used. Disperse dyes today constitute the second largest sector in the dyeing industry and it is closely related to the growth of PET using. The disperse dyes are sparingly soluble in water and must be dispersed with the aid of a surfactant in the dyebath. It is essential to apply a dispersing agent in dyebath to improve dye aqueous solubility; retains dye in consistent dispersion throughout dyeing by enclosing single dye particle with a protective film.
