Frequently Asked Questions

Traditionally, water has been a popular medium used in dyeing, finishing, cleaning of textile materials. It makes the textile industry as one of the largest consumers of water resources. According to the World Resources Institute, the conventional fabric dyeing processes consumes roughly 5 trillion liters of water every year to meet the increasing demand in the world for new apparels. Moreover, according to the United Nations World Development Report, 80% of the global wastewater is dumped into the environment without adequate treatment. In a world where usable water resources are becoming alarmingly scarce such that water has even started trading on Wall Street as a 'Futures Commodity' to join the likes of Gold and Oil, it is imperative that we need the development of more sustainable solutions in the world. That's where SUPRAUNO®, developed by Deven Supercriticals, comes in. It is a patented sustainable waterless dyeing technology that uses Supercritical CO2 to revolutionize textile dyeing. Our innovative solution allows the waterless use of conventional dyes and their traditional tri-chrome recipes in the sustainable dyeing operation of various man-made and natural fabric types, including Cotton, Polyester, Nylon, Viscose, Linen, Wool, Acrylic and Blends with the help of 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. The use of our technology not only reduces the water use by 76% but also reduces the use of auxiliary chemicals by 90% which would have ended up in the wastewater. We believe that our technology could have a significant positive impact on the environment and help the industry shift towards a more sustainable and responsible way of textile dyeing

SUPRAUNO® differs from Prior-Art Supercritical CO2 technologies in its ability to dye a variety of fabric types. It not only is a viable solution for Polyester, but also can be used to dye other fabric types such as Cotton, Nylon, Viscose, Acrylic, and their blends. Due to the innovative, patented steps followed by SUPRAUNO®, it allows the use of conventional dyes already used in the industry in the sustainable dyeing process, improves dye utilization and cuts the batch time by half. Moreover, the simple design helps in an easy scale-up to commercial scale and is economically viable to be implemented. SUPRAUNO® is a complete, viable sustainable solution for efficient textile dyeing!

Unlike Prior Art Supercritical Technologies used for Dyeing of Fabric that only focus on Polyester, SUPRAUNO® can be used for Polyester, Cotton, Nylon, Viscose, Linen, Acrylic, Flax, Blends etc.

Our novel, patented technology, SUPRAUNO®, is truly economically viable to be implemented in the industry with dyeing costs being significantly lower as compared to conventional water based dyeing. This is possible as our technology avoids two bath dyeing for Cotton-Polyester blends and uses much lesser quantity of auxiliary chemicals, uses no salt, thus substantially reducing the pollution, water and energy load. ​ Similarly, SUPRAUNO® is also suitable for dyeing & finishing of various other Man-made & Natural textiles like Polyester, Nylon, Acrylic, Cotton, Viscose, Linen, Wool etc. and blends. ​ Thus, SUPRAUNO® is very unique in the world and can play an important role for truly accomplishing sustainable compliances by the Textile Industries vis-à-vis Conventional / Traditional processes which have a negative impact on the environment & customer preferences.
