From the Sector

Ten positions of the new Flex-6 concept for manufacturing polyamide 66 industrial yarns were recently commissioned at Sinowin Chemical Fiber Co., Ltd., China. Shortly before the exhibition Techtextil opens its doors in Frankfurt, Germany, from May 9-12, 2017 the Segment Manmade Fibers of the Swiss Oerlikon group has announced this project.
The benefits of the new machine concept include components that are optimized to the respective application, which considerably reduce the required space compared to conventional solutions and its optimized energy consumption. Oerlikon Barmag Sales Director Oliver Lemke: “With its new godet configuration, the Flex-6 concept promises an unparalleled price-performance ratio for the production of high-end yarns. Sinowin is therefore the first industrial yarn manufacturer in China to deploy our new technology.”

Sinowin is completely committed to creating value for its customers. Here, quality and innovative technologies are absolutely essential, confirms General Manager Sheng Jian Wang: “We are striving to become a leading ‘Made in China’ enterprise in the chemical fiber industry. For this, we require state-of-the-art technologies that manufacture quality products. Oerlikon Barmag has an excellent reputation – above all for the PA66 industrial yarn process. To this end, there was no other partner for us.”            

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.
