Teijin Frontier has developed a new high-performance polyester fabric which combines the elegant appearance and texture of natural fibres made from yarns of random thickness with advanced functionalities such as cool touch, anti-stickiness, quick dry, opacity and UV protection.

There is strong demand for textiles that offer a natural and elegant appearance for casual and fashion apparel Teijin says, but at the same time, consumers are looking for value-added comfort features like those found in high-performance sportswear. Until now, it has been difficult to combine these high-performance features with a natural fibre-like appearance and texture.

The new fabric is being produced from a unique, four-lobed, flat cross-section filament yarn with random thicknesses, achieved through proprietary spinning technology. These thickness variations create pleasing irregularities in appearance and a dense texture similar to those of natural fibres. To support circularity, the newly developed fabric is made with 100% recycled polyester and Teijin Frontier also exploits special dyeing and finishing technology and post-processing techniques following the knitting or weaving.

The newly developed fabric’s capillary action wicks away perspiration via grooves on the fibre surfaces and the full dull yarn contains titanium oxide to promote a cooling sensation as heat is transferred from the skin. The flat cross-sectional shape of the fibres increases skin contact area and the random thicknesses of the yarn forms irregularities on the surface of the fabric and prevents its adherence to the skin. A a light-scattering effect creates opacity and helps to block UV radiation. 

Teijin Frontier plans to begin sales of the fabric this year and aims to sell 250,000 metres by fiscal year 2027.
