The 2250L supercritical CO ₂ waterless dyeing equipment undertaken by Guangming Institute uses CO ₂ as the dyeing medium, without the use of water and chemical additives, and truly achieves no sewage discharge, which promotes the innovation of traditional water-based printing and dyeing
.
Although there have been researches on this technology at home and abroad, it has not been industrialized
.
The dyeing efficiency of the industrialization demonstration line started this time can be shortened from 8~12 hours of traditional water dyeing to 3~4 hours, and the annual production capacity can reach 1,000 tons.
