About SUPRAUNO®

SUPRAUNO® developed by Deven Supercriticals is a patented sustainable waterless dyeing and finishing technology that revolutionizes textile dyeing using Supercritical CO2 as the medium instead of water. Our innovative solution, for the first time in the world, allows the waterless use of conventional dyes & their traditional tri-chrome recipes in the sustainable dyeing operation of various man-made and natural fabric types, including Cotton, Polyester, Nylon, Viscose, Linen, Silk, Acrylic and Blends using Supercritical CO2.

SUPRAUNO® further requires no reduction clearing for polyester, uses no salt for cotton, improves overall dye utilization, follows single bath dyeing of textile blends and uses up to 90% lesser auxiliary chemicals which otherwise would have ended up in the wastewater. Thus, it substantially reduces Effluent Treatment Plant (ETP) load, lowering batch times leading to ~50% lesser Energy Load. Experience the benefits of an eco-friendly dyeing technology to color all with SUPRAUNO®.

Steps involved in SUPRAUNO®

Precoating a Thin Layer of Dye solution onto the Textile

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 a greater contact area.

Subsequent Drying and Rolling into a Beam

Then, the precoated textile goes through a drying chamber and is rolled into a beam, ready to be fed into the supercritical fluid dyeing vessel.

Dyeing Completed using Supercritical Carbon Dioxide

The precoated textile is fed into the dyeing vessel where supercritical carbon dioxide is filled into the dyeing vessel at a suitable pressure and temperature to complete the dyeing process followed by a mild washing step.
