Handbook of Textile and Industrial Dyeing
While aiming to create methods for fibre recycling, the question of colours in waste textiles is also in focus; whether the colour should be kept or should be removed while recycling textile fibre. More knowledge is needed for colour management in a circular economy approach. The research included the use of different dye types in a cotton dyeing process, the process for decolourizing and the results. Two reactive dyes, two direct dyes and one vat dye were used in the study. The objective was to evaluate how different chemical refining sequences remove colour from direct, reactive and vat dyed cotton fabrics, and how they influence the specific cellulose properties.

Purpurin showed much better resistance to photofading than munjistin. It was found that the type of mordant and the method of mordanting significantly affected the rate and extent of photofading. The use of copper or ferrous sulphate gave high resistance to fading, whereas stannous chloride or alum did not.

Scientific Research An Academic Publisher. Affiliation s. Textile industry involves processing or converting raw material into finished textile materials via several processes which consume large amount of water and generate polluting waste effluents containing nonbiodegradable and dissolved toxic substances . Among the various processes, fabric dyeing releases large amounts of toxic chemical products, for both human health and environment, which results in a mixed wastewater composed of residual dyes, auxiliary chemicals, surfactants, chlorinated compounds and salts  . Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. It is normally done in a solution containing dyes and chemicals. The diffusion of dye into fiber depends on pH, temperature and employs auxiliary agents as well .
