Synthetic fiber operations begin with production of Cashmilon™ acrylic staple fiber in Fuji (production ended March 2003)
In the early decades, our business diversification was centered on utilization of ammonia derivatives. The acrylic fiber business was a notable example, using ammonia to make acrylonitrile which is then polymerized. Among the synthetic fibers, acrylic fiber has characteristics similar to wool. It has been used for a wide variety of garments. Although most synthetic fibers produced in Japan during this period were based on technology introduced from abroad, we developed our own technology for acrylic fiber. Suggestive of high-end cashmere wool, the product name Cashmilon™ was chosen from among suggestions by employees through a campaign in the internal magazine.
