ecodye – Swiss companies Schoeller and Textilcolor develop revolutionary polyester dyeing (4/10/17)
ecodye is an exciting new development, resulting from a Swiss collaboration between textile
manufacturer Schoeller and the auxiliaries and dyes specialists at Textilcolor. ecodye is a new
auxiliary concept used 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
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.
