New polyester dyeing process developed

April 24th, 2017 / By: / EcoNote

Swiss companies Schoeller and Textilcolor have collaborated to create a new auxiliary concept used in polyester dyeing. “Ecodye” technology is said to accelerate the dyeing process and, in turn, cut costs and preserve the environment.

Used on polyester yarns and piece goods, Schoeller says that it will shorten the heating phase, which can accelerate the process time by more than 30 percent. The company also reports a 20 percent reduction in energy consumption and a 25 percent reduction in required water, citing that goods can be cleaned in the cooling dye bath.

The companies’ goals were to provide textile customers with a technology that yields good dyeing levelness; avoids spots and dye agglomeration; avoids precipitation on the goods that arise as a result of polyester oligomers; and provides shade stability for reliable reproduction, batch to batch.

The technology is being used by polyester processing customers in categories including outdoor, sportswear and technical knitted fabrics, primarily in Europe, South and Central America, Turkey, Bangladesh and China.

Ecodye is bluesign® certified and is reported to be suitable for all textile forms, machines and substrates, as well as existing dye recipes.

Headquartered in Switzerland, Schoeller Textil AG manufactures high-performance textiles, specializing in the sustainable development and production of innovative textiles and textile technologies. Textilcolor AG stands for the development, manufacture and distribution of textile auxiliaries, dyes, pigments and optic brighteners.
