Fafedry completed yet another R&D project aimed at achieving more sustainable dyeing and finishing processes – specifically the fade-out process, which gives the perception of a used product and is increasingly in demand. It is a chemical process by which the company removes environmental hazards.
“Technically, the traditional ‘fade out’ process consists of using a chemical product, potassium permanganate or its substitutes, with the aid of perite or a small diameter stone to give the wear effect”, explains the company to T Jornal.
“The use of permanganate encompasses several dangers to the environment. In addition to using this product, a neutralization process is also necessary with sodium metabisulfite use, which is also harmful to the environment”, continues.
According to the company, the ‘Old Fake Dye’ project resulted in a solution that eliminates the use of potassium permanganate and sodium metabisulfite, which “reduces by 20% the consumption and discharge of wastewater, by 30% the consumption of electricity and in 5% the possibility of defect”.
