Nano-Dye™ Process

Exhaust dye process that changes the negative charge of raw cotton when submerged in water to a positive charge, making attraction stronger with negative dye stuff. 20% of global industrial water pollution comes from the treatment and dyeing of textiles. The process uses up to 75% less water than the conventional reactive exhaust dye process. It saves time as the process takes 5.5 hours compared to the traditional 8 hours. Produces less salt than conventional methods (salt traps other toxic chemicals when bound into a solid). 70% lower TDS, makes ZLD plants inexpensive. Exhausts 97% of dyes and does not need salt in the dying process. Improves the wet rub fastness of dark colors (reduces exchange of color).
