ecodye – Swiss companies Schoeller and Textilcolor develop revolutionary polyester dyeing

The technology accelerates the dyeing process and contributes to cutting costs, while at the same time helping to preserve the environment with a low level of demand on resources. 

Less time, less water, less energy – the new ecodye auxiliary concept allows eco-friendly and cost-saving dyeing processes for polyester yarns and piece goods. It shortens the heating phase, thus accelerating process time by more than 30 percent. At the same time, it reduces energy consumption by 20 percent and the water requirement by 25 percent, as the goods can be cleaned in the cooling dye bath.

In addition, ecodye improves the dyeing levelness in polyester textiles. Spots and dye agglomeration are almost completely avoided, and the precipitation on the goods that arises as a result of polyester oligomers are no longer evident. ecodye provides good shade stability and avoids reproduction problems from batch to batch, thus reducing the rate of double staining and increasing the capacity utilization and productivity of the dyeing mill on a long-term basis.

Following a successful launch phase, ecodye has already been able to provide numerous positive test results. The technology is being used by polyester-processing customers in categories including outdoor, sportswear and technical knitted fabrics, primarily in Europe, South and Middle America, Turkey, Bangladesh and China. “ecodye is an auxiliary of the future. It requires not only great expertise in the development of the auxiliary concept but also in the textile application. We are pleased to have been able to develop this advanced product in successful partnership with Textilcolor,� said Hans Kohn, COO of Schoeller Technologies AG.

The new technology has been proven to provide an eco-friendly and cost-saving dyeing process. ecodye is bluesign®-certified and is suitable for all textile forms, machines and substrates, as well as existing dye recipes. It requires no additional investment or conversion. The potential savings for each application can be individually computed using a specially-developed calculation program.
