ecodye – Swiss companies Schoeller and Textilcolor develop revolutionary polyester dyeing

Frozen drop of waterecodye – an exciting new development, resulting from a Swiss collaboration between
textile manufacturer Schoeller and auxiliaries and dyes specialists at Textilcolor. ecodye is a new
auxiliary concept used, in particular, in polyester dyeing processes. 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.
