Water-based functional layers

Trans-Textil GmbH is presenting its Purable functional systems based on aqueous technologies for the first time at Techtextil in Frankfurt am Main, June 21–24, 2022.

The company from Freilassing in Bavaria completely avoids organic solvents in production.

The basis of the Purable functional layers are specially developed, solvent-free formulations, which allow specific control of technical properties such as air permeability and breathability. The barrier systems are very elastic and, in combination with elastic textiles, ensure a comfortable stretch effect and a pleasant soft feel, even in multi-layer composites. With more than 50 cycles at 60°C according to ISO 6330, Trans-Textil has also proven the excellent washing properties of the new systems. When used as classic softshell products, the use of PTFE can be completely dispensed without any loss of the decisive parameter of water vapor permeability.

To ensure that they are watertight, the hydrophilic, solvent-free Purable membranes at Trans-Textil are processed into individual multi-layer composites using the precisely controlled in-house Point-in-Point lamination process and achieve impermeability values of over 10 meters water column.

Synergy effects with PFC-free and solvent-free technologies

In the further functionalization for weather protection applications such as workwear, civil service, outdoor and sports clothing, Trans-Textil uses its proven PFC-free Clean4Green finish, which is adapted to the respective laminate composite. “With this alternative and environmentally friendly surface finish, we are already achieving water repellency that is comparable to conventional fluorine-based formulations. The actual tightness against oil and other chemicals is provided by the membrane system,” says Matthias Krings, Managing Director of Trans-Textil GmbH.

For the fashionable design of the functional laminates, Trans-Textil relies on the environmentally friendly transfer printing process, in which only the natural solvents water and alcohol are used. In addition to the individual design options from logo printing to fullcolor motifs, the sustainable technology offers high color fastness and abrasion resistance.

For optimal tightness at the seams, Trans-Textil has developed solvent-free seam sealing tapes for all common laminate types. The water-based Topaz Elements tapes enable high-quality functional textiles to be used for a long time, for example in shoe laminates, workwear, outdoor, leisure and sportswear as well as in technical ready-mades. The tapes can be customized in terms of technical properties, dimensions and design. They are suitable for washing at up to 60 °C.

Vegan label for membranes, textiles and laminates

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 also expand Trans-Textil's sustainable portfolio. All components and processes for Trans-Textil’s own products and contract processing are also tested and certified for their human-ecological soundness in accordance with the current requirements of Standard 100 by Oeko-Tex.

Through the increased use of aqueous and PFC-free technologies, Trans-Textil significantly reduces the ecological footprint along the supply chain as well as in production, during processing and use.
