Denim dyeing with a reduced footprint

A pretreatment and dyeing process for laser-friendly, easily washable denim, DENIM HALO leaves a reduced environmental footprint by avoiding processes like manual hand scraping or potassium permanganate spraying. It also helps reduce caustic soda use in sulfur dyeing, which lowers the effluent load and improves weaving efficiency. DENIM HALO combines Archroma’s DIRSOL® RD special pretreatment with its DENISOL® indigo dyes, including an aniline-free formulation, or DIRESUL® sulfur black, sulfur blue or sulfur colors dyestuffs for a ring-dyeing effect. This creates worn or distressed washdown effects while reducing yarn shrinkage and improving garment tensile strength.
