Our aim was to find a way to reduce water in the coloring process. The conventional dyeing process uses hot water and chemicals to make the color adhere to the synthetic fiber, consuming water, energy and emitting CO2.

Dope dyeing instead diverts from traditional wet processing because of its reduced environmental impact. Typical of recycled polyester, it involves adding color pigment “upstream”, directly to the melted plastic solution before the fiber is made. Unlike traditional processes where yarns are produced and then dyed, with dope dyeing the pigments are trapped inside the recycled plastic after it cools to a solid form, becoming part of the new, stronger yarn. With this approach, dyeing can be done by hot transfer without immersion in water.

Benefits of DOPE DYEING

  • Optimises the use of water reserves
  • Eliminates the risk of dye emission in the water
  • Reduces the use of chemicals
  • Reduces CO2 emissions
  • It uses less production energy
  • Permanently dyes the fibers avoiding future loss of color from wash to wash
