Trans-Textil, a German developer and manufacturer of functional textiles, presented its Topaz Purable functional systems based on aqueous technologies to a wider trade audience for the first time this summer at Techtextil in Frankfurt.
The company completely eliminates the use of organic solvents in production. In combination with its PFC-free Clean4Green® finish (matched to the respective laminate composite), water-based Topaz Elements® seam sealing tapes, environmentally friendly transfer printing process and vegan-certified or recycled components, the result is a technically extremely flexible and sustainable overall concept for functional textiles, according to Trans-Textil. The basis of the Purable functional layers are specially developed, solvent-free formulations that enable targeted control of technical properties such as air permeability and breathability. According to the manufacturer, the barrier systems are very elastic and, in combination with elastic textiles, provide a comfortable stretch effect and a soft feel, even with multilayer composites. With more than 50 cycles at 60°C according to ISO 6330, the new systems also have excellent washing properties. When used as classic softshell products, the use of PTFE can be completely eliminated without losing the crucial parameter of water vapor permeability. To ensure waterproofness, the hydrophilic, solvent-free Parabel membranes are processed at Trans-Textil into individual multilayer composites using the company’s own, precisely controlled Point-in-Point® lamination process, achieving waterproofness values of over 10 meters water column.
Membrane systems, textiles and lamination processes that have been awarded the “100% Vegan” test mark by the Pirmasens Testing and Research Institute (PFI), as well as an increased proportion of recycled components, add to Trans-Textil’s sustainable portfolio. All components and processes for the company’s own products and contract finishes are also tested and certified for their human ecological compatibility in accordance with the current requirements of the Oeko-Tex® Standard 100. By increasing the use of water-based and PFC-free technologies, Trans-Textil is significantly reducing its environmental footprint along the supply chain and in production, processing and use.
Trans-Textil says it has created ideal conditions by building long-term close partnerships in a predominantly regional supply chain. The company continuously invests in a qualified team, its own application technology and textile technology laboratories, and plant technology for processing aqueous formulations, which offer short distances from development to implementation at the Freilassing site in Bavaria (southern Germany).
