Our solution: Sympatex products save water
According to estimates from the World Bank, dye processes used by the textile industry account for around 20 percent of the world’s industrial water contamination. This is despite the fact that polyester dye technologies which conserve significantly more water than traditional dye processes, while massively reducing the use of chemicals, have been available for some time.
These apparel innovations from Sympatex, made with fully-recyclable textile surface materials, combine the advantages of both raw material recycling processes and the spun-dyed technology. With this dye technology, water consumption can be reduced by around 75 percent, while decreasing the use of chemicals by as much as 90 percent. In combination with the 100 percent polyether/polyester Sympatex membrane, which uses 50 percent less water during the manufacturing process than a commercially-available PTFE membrane, there is no need to sacrifice performance. The articles, which are ideally-suited for outdoor and ski applications, and even for the fashion world, are 100 percent water- and wind-proof, in addition to optimally breathable, thus offering further proof that it’s possible to combine sustainability and performance in a single product.
Water savings through spun-dyed technology
With this spun-dyed technology, instead of adding the dye to the finished textile product, it’s mixed into the raw material granulate. This not only improves the penetration intensity of the dye in the thread. The process also offers significant advantages with respect to color harmony and the reproducibility of the hue.
Water savings through Sympatex laminates
At the beginning of 2017, Sympatex has committed itself to using more and more recycled polyester for its uppers and lining materials as part of its “Agenda 2020”. The advantage: if you laminate the Sympatex membrane made of pure polyether/ester with recycled polyester uppers and liners, you will get pure laminates that can easily be added to the closed textile loop at the end of their product life cycle. Furthermore, recycled polyester consumes much more water compared to virgin polyester. In fact: If you compare the production of 1 kg recycled “New Life” fibres with 1kg oil-based polyester fibres, then the 90 percent water savings are excellent or in other words: you only need around 3 instead of 60 litres water for 1 kg fibres.
