The fabrics are a combination of Advansa’s ‘ThermoºCool Eco’ and Lenzing’s Tencel cellulosic fibre. The new Advansa fibre is a PTT polymer based on ‘Bio-PDO’ which is derived from renewable raw materials such as corn sugar.

Together with Tencel this fabric is said to offer a high moisture absorption capacity due to Tencel yarns on the outer side of the fabric which rapidly removes moisture and the multi-channel cross sectional profile of the Advansa PTT ‘ThermoºCool Eco’ on the inner side which wicks moisture to the surface.

This combination of yarns is said to guarantee a drier skin surface during sports activities.

“Depending on the mass per unit area in question, textiles can be designed for various applications such as thermoregulating underwear, socks or textiles offering protection and performance solution for all environmental conditions,” said Advansa in a press statement.
