[PEOPLEGATE] The use of functional materials is expanding from outdoor activity apparel to everyday wear. German material brand Sympatex is introducing materials that can be applied to clothing and shoes worn in the city, based on membrane technology that responds to rain and wind.

Since 1986, Sympatex has developed pore-free membrane technology in Europe. This material is used in clothing and footwear as well as workwear and personal protective equipment. The polyester-based membrane is described by Sympatex as combining waterproof, windproof performance with the ability to expel moisture generated during wear.

Applying waterproof and windproof functions in everyday clothing and footwear

In urban settings, it is common to encounter wind and rain during commutes or travel. Considering these conditions, Sympatex applies the membrane's waterproof, windproof functions and stretchability to materials for clothing and footwear.

Unlike methods using microscopic pores, Sympatex's membrane is designed to move internal water vapor through hydrophilic materials. The company explains that this offers the function of blocking external water and wind while expelling moisture generated during wear.

Polyester-based material with recycling in mind

Sympatex emphasizes its PFAS-free polyester-based membrane as a core technology. It has also developed mono-material constructions using polyester for the membrane, outer fabric, and lining, with the potential for recycling after product use. However, recyclability of finished products depends on other components and collection and processing methods.

The company has set a goal to establish a circular system from raw materials to finished products by 2030. It continues material development aiming to reuse fibers as raw materials while maintaining performance required for functional clothing.
