Australian scientists have developed photochromic wool products
Wool clothing can change color in the sun and block harmful UV rays. This new research from Australia’s Deakin University may trigger next season’s fashion trend.
Tong Cheng, a PhD student at Deakin University’s Center for Materials and Fiber Innovation, under the guidance of Drs Tong Lin and Rex Brady, invented a polymer that can preserve photochromic dyes and attach them to the surface of wool fibers It achieves a breakthrough in traditional dyeing methods.
This special polymer contains a large number of small pores that can firmly lock the dye. In order to ensure the market value of this technology in clothing, the polymer must not affect the texture of the wool itself, and must be durable and photosensitive. Cheng explained: “Textiles using polymers are almost identical to ordinary wool products. The new products maintain the softness and drape of wool and are not easy to fade after washing.”
Cheng said that this polymer Another advantage of the clothing is its UV protection. She said, “We found that this polymer can absorb harmful ultraviolet rays in sunlight. Using it in wool can enhance the ultraviolet absorption capacity of textiles, thereby further improving the SPF (sun protection index) value of wool clothing. The first round of experiments showed The harmful rays emitted are almost completely blocked.”
The research results have been recognized by two major awards, namely the “2006 Borland Forum Award” issued by the Australian Materials Association and the Australian Wool Development Company and German Wool “Excellence Award in Wool Science” jointly presented by the Institute (DWI).
