Schutzen Chemical Group, the specialty chemical manufacturer, unveils a sustainable denim process that replaces the indigo & sulfur dyes while eliminating the use of hydrosulfite – thus reducing the amount of dye use and water consumption.
The novelty does not require installation of any new machinery.
The new process is based on biodegradable polymeric ready-to-use liquor solution that allows the warp beams yarns or open width fabrics to be dyed/printed or coated using pigments, natural dyes or reactive dyestuff instead of indigo or sulfur.
Notably, the process can be done with rope dyeing, coating or printing.
The use of warp beams in rope dyeing/coating or padding eliminates the need for reducing the indigo to its leuco form using hazardous chemicals like sodium hydrosulfite.
Furthermore, the use of new natural denim process allows obtaining a wash down effect even with reactive dyes as well as pigments.
