Asahi Kasei Corporation announced that the company has developed anti-pilling type superfine denier acrylics. "Cashmilon ff" is set to sell its staple fibres for Autumn/Winter 2002/03 season. Asahi plans to sell the new fibre to the underwear, knitwear, socks and knitted fabric sectors. Toru Egami, division manager for Cashmilon, said that researchers had finally overcome the difficulty of combining the softness of microfibre staple and anti-pilling properties. Fineness of Cashmilon ff is 0.9 denier.
