Deven Supercriticals has showcased the commercial scale
operation of SUPRAUNO®, marking a significant step forward in sustainable
textile dyeing. The demonstration highlights the actual machinery, process flow
and real time fabric dyeing, offering rare visibility into a waterless dyeing
system already operating at industrial scale.
SUPRAUNO® uses supercritical CO₂ as the dyeing medium,
eliminating the need for water during dyeing and finishing. The patented
technology allows mills to use conventional dyes and existing trichrome
recipes, enabling easy adoption without changes to current dye chemistry. The
system works across cotton, polyester, nylon, viscose, linen, wool, acrylic and
blended fabrics, addressing a wide range of industry needs.
The process removes salt usage in cotton dyeing and
eliminates reduction clearing for polyester. Dye uptake improves while
auxiliary chemical consumption drops by up to 90%, sharply reducing effluent
treatment plant loads. Shorter batch cycles cut energy demand by nearly 50%,
delivering strong operational and environmental gains.
India’s textile wet processing sector consumes over 3.5
billion litres of water daily, making scalable solutions like SUPRAUNO®
critical for long term sustainability. The technology positions Indian
innovation at the centre of global efforts to decarbonise and detoxify textile
manufacturing.
