Polar bear fur-inspired sweater is thinner than a down jacket — and just as warm
admin 2023/12/27 15:12The synthetic fibre is an aerogel coated with polyurethane and is flexible, washable and wearable.
Chinese scientists have created a sweater as snuggly as this bear, using synthetic fibers. A sweater knitted from a fibre that mimics polar bear fur offers as much warmth as a down jacket, despite being one-fifth as thick, according to a study published today in Science1. The fibre — made from a light, synthetic material known as an aerogel — maintains its heat-trapping properties even after being stretched, washed and dyed.
The proof-of-concept fibre might one day be used for clothing that need to be lightweight and durable — such as sportswear, military uniforms and spacesuits — without the need for animal fur or down, says study co-author Weiwei Gao, a materials scientist at Zhejiang University in China.
