Teijin Frontier: new highly water-repellent stretchable fabric
Based on the company’s existing water repellent fabric, the new design incorporates a convex structure with horizontal surface tension which is smaller than waterdrops, allowing water to run off the surface smoothly. The fabric achieves a grade four out of five in water-repellent rating initially, and a grade three rating after being washed 20 times. It is able to stretch by 10%, and maintains water-repellency when stretched thanks to its flexible structure; conventional water-repellent fabrics are unable to achieve similar levels of stretchablility because of the high density of their yarn arrays.
The demand for highly water-repellent apparel, including stretchable clothes such as trousers and outer-clothing applications, is growing in response to the increased frequency of heavy rain in Japan.
