SHANGHAI – April 13, 2022 – Avient today launched CESA™ fiber additives, a new generation of heat-preservation additive formulations for fiber and textile applications to help brands more easily meet consumer demand for lightweight, comfortable outdoor clothing.  

Fabrics made with CESA fiber additives can absorb more heat when exposed to solar rays. Photothermally active particles added to the fibers help transform the energy of invisible light rays into heat for enhanced comfort in cold temperatures. When exposed to a light source for 10 minutes, this new generation of heat-preservation additives can provide a temperature increase of up to 12°C for PET and PA fibers. This represents a performance improvement of up to one-hundred percent over Avient’s previous generation of additives which have been the leading solutions in fiber industry. 

“Today’s lifestyles often involve outdoor activity, even in cold weather, and that leads to increasing demand for functional clothing that is warm while remaining lightweight,” said Say-Eng Lee, Vice President and General Manager of Color & Additives Asia at Avient.  “Our continuous innovation and improvement in fabric solutions is a demonstration of how we work to help our customers meet evolving consumer needs and stay ahead in a dynamic marketplace.”

CESA fiber additives are intended for use in applications including clothing, home textiles and technical fabrics for thermal insulation. They also can be combined with specific colorants into a single, customized masterbatch to simplify manufacturing.
