Seawool maker ushers in insulation
Creative Tech Textile / Hans Global, a company based in Taiwan, will be exhibiting at Premiere Vision next week and introducing a new insulation made from its patented Seawool yarn, which is composed of recycled PET plastics and discarded oyster shells. 

For the new product range, Smawarm, Seawool fibres are given a spiralled shape that increases thei ability of the filler to lock in warmth. The thermal insulation is also said to wick moisture away, dry quickly, and has antibacterial and static-electricity resistant properties. 

The company said that 1% of global shell waste could be used to make up to 900 tonnes of Seawool fibre. In 2023, it had turned 100 tonnes of oyster shells and 300 tonnes of post-consumer plastic waste into fibre.

Building on the legacy of Seawool, Smawarm “delivers lightweight, breathable insulation that offers warmth and comfort with a biomimetic twist,” commented Eddie Wang, founder and CEO of Creative Tech Textile / Hans Global.
