Investigate Waste Problems from Textile Industries
The textile business is problematic. Due to the fact that the discharged wastewater from textile industry carried large amounts of chemicals, not to mention its energy consumption, air emissions, solid wastes and odours. On the other hand, the recent raising of the fast fashion business has no doubt increased our concern about the textile wastes, toxic chemical uses and microfiber ocean pollutions. The twelve-dyes project was motivated by providing feasible solutions for such environmental issues, and we primarily focused on the dye waste issues from the textile industry.
The composition of textile waste stream will vary depending on the fabric being dyed, the colours, and the method of dye application. For this specific case, the fabric of interest is silk, the method of dye application is printing and the pigments making up the colour were unknown. The expected compounds in the waste stream are a.o. urea (necessary for fixing the dyes to the fabric), thickeners, detergents, defoamers and dye pigments.
