GTI's Aquavent

Green Theme International (GTI), the creators of sustainable and water-free textile technologies, has just received the ECO PASSPORT certification by OEKO-TEX from the Hohenstein Institute (Germany) for GTI’s new Aquavent™ water-repellency chemistry, which is poised to transform finished fabrics in the technical apparel and fashion industries worldwide. GTI’s new Aquavent technology will be presented in several styles with Marmot Mountain LLC, a leading outdoor manufacturer, at the Outdoor Retailer Trade Show (Jan 25-28) in Denver, Colorado and at the ISPO Trade Show (28-31) in Munich, Germany.


The Hohenstein Institute’s rigorous testing process evaluates chemistries and processes of companies worldwide. Their ECO PASSPORT certification—a mechanism by which manufacturers and suppliers demonstrate that their products can be used in sustainable textile production—gives GTI’s Aquavent global recognition for its clean chemistry.

“This important certification demonstrates GTI’s leadership in sustainable fabric technologies in the outdoor industry and farther afield. It validates the efficacy of GTI’s technology and our commitment to eliminate water use and pollution in textile production,” says Brian LaPlante, GTI’s marketing director, who will be attending both Denver and Munich outdoor trade shows this month.


After five years of research and testing, GTI has developed an entirely new technology, which eliminates water usage and harmful chemical discharges from traditional DWR (Durable Water Repellency) finishing processes. GTI’s long-awaited technology completely eliminates harmful PFC’s and outperforms existing C6, C8 and PFC-free DWR’s.
