From the Sector

Compared to the past years we are a little late in advertising the upcoming 13th China International Recycled Polyester Conference & Exhibition in Shanghai at September 05 – 06, but as during the past twelve years we are expecting again an succesful international event with a large number of Mainland Chinese and Oversees delegates, speakers, exhibitiors and sponsors. The Conferece venue is the Holiday Inn Shanghai Hongqiao this year, which is located near the Hongqiao Airport and so about 30 min by car from the city and 15 min walking distance to the subway No. 6. With a production of about 8 Mio t/a the Chinese polyester recyclers are producing all kind of textile intermediates like staple fiber, POY, DTY, FDY, BCF, technical yarn and spunbond products based on mainly PET bottle flakes. Meanwhile also bottle-to-bottle and bottle-to-film or strapping technology is on the way. Therefore conference and exhibition are an ideal meeting place for those who are involved in the whole production chain including engineering and equipment manufacturer. Very interesting will be discussion and latest information about the impact of new governmental action to improve environmental standards. This new development might be of importance especially for those who are involved in raw material sourcing.

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.
