SUPRAUNO® CO2 Dyeing Process for Polyester-Cotton Fabric
Features
01
Each SUPRAUNO® commercial plant consists of a set of three dyeing vessels that operate synchronously in a staggered manner, resulting in a semi-continuous operation.
02
The SUPRAUNO® dyeing process is a closed-loop process wherein 95% of the CO2 used in each batch is recycled back into the CO2 tank.
03
The SUPRAUNO® dyeing plant can dye knitted, woven, and non-woven fabrics. It can also be used for dyeing yarn, garments, and fibers.
04
Any dissolved dyes dissolved in the CO2 solvent during the dyeing process inside the dyeing vessel is separated using a separator, such that only pure CO2 goes back into the CO2 tank.

01
Precoating of Thin Layer of Dye solution onto the Fabric
The precoating of the textiles with the dye solution containing the dyes, chemicals and finishing agents significantly improves the efficiency of interaction of the dyes and chemicals with the Supercritical Carbon Dioxide due to greater contact area.
Steps involved in SUPRAUNO®
02
Subsequent Drying and Rolling into a Beam
Then, the precoated fabric goes through a drying chamber and is rolled into a beam ready to be fed into the supercritical carbin dioide vessel.
