Last January, at the Heimtextil Trade Fair in Frankfurt (Germany), a new polyester and viscose pillow and duvet filling fibre was launched, the fruit of a partnership between Advansa, polyester manufacturer, and Lenzing, a viscose specialist. Sold under the name Suprelle Fresh & Tencel (the names of two components), this new product releases over 57 % more moisture than a standard 100 % polyester duvet. And indeed, all discerning consumers appreciate the importance of releasing moisture; an average sleeper loses half a litre of water through perspiration each night, which must be released outside the duvet to avoid discomfort.
