A next-generation material that uniquely combines contact cooling functionality with the prevention of the stickiness caused by sweat has been developed by Tokyo-headquartered Teijin Frontier based on a new dual-layer knitted structure.

The inner layer alternates differing Waveron polyester filament yarns – the conventional hydrophilic types and a new hydrophobic variant – in order to both absorb perspiration and keep it it from adhering to the skin. An outer layer disperses absorbed perspiration to the outside of the fabric.

Teijin Frontier plans to promote and sell the fabric for the 2026 Spring/Summer sports and outdoor apparel season, in both domestic and international markets. In advance of that season, the company aims to sell 100,000 metres of the material to be subsequently incorporated into functional apparel. By fiscal 2028, the company expects to sell a million metres of the fabric.

Until now it has been challenging to deliver textiles that provide both contact cooling and sweat stickiness prevention because contact cooling requires the material’s contact area with the skin to be enlarged in order to improve heat conduction, while sweat stickiness prevention requires reduced contact with the skin.

Waveron yarn contains titanium oxide, which promotes a cooling sensation as heat is transferred from the skin to the fibre and has a flat, cross-sectional shape that increases the skin contact area. Additionally, the non-crimped yarn maximises the air gaps between fibres.

The new material uses 100% recycled polyester and features water-repellent technology made without per- and polyfluoroalkyl substances (PFAS).
