DyStar Getzner Partner For Electrochemical Dyeing Trials

DyStar, Getzner Partner ForElectrochemical Dyeing TrialsAustria-based Getzner Textil AG has signed a cooperation agreement with the Technology Team Electrochemistry Textile (TET), headed by DyStar Textilfarben, Germany. Under the agreement, Getzner will be the first company to use DyStars patented electrochemical dyeing process in pilot trials. Getzner will use the technology to vat-dye yarn on a package-dyeing unit. Other members of TET are the Institute for Textile Chemistry and Textile Physics at Austrias Innsbruck University, and Germany-based De Nora Deutschland GmbH.The new electrochemical dyeing process uses an electric current to reduce the dyes with the aid of a regenerable Fe2+/Fe3+ redox system. Conventional application methods use reducing agents that cannot be regenerated.The pilot trials will help TET further refine and develop the dyeing process. Dr. Wolfgang Schrott is in charge of the project for DyStar. He expects electrochemical dyeing to be suitable for a wide range of other applications including vat, indigo and sulfur dyes.In other company news, DyStar now markets all of its disperse dyes under the Dianix® brand. Following the acquisition of Germany-based BASFs textile dyes business, the branding aims to bring together Dianix dyes with the former BASF Dispersol® and Palanil® ranges.February 2002
