This article presents the process involved from the creation of Ultra fine fiber to the development of its applications and discusses the R&D strategy adopted. The development of technology for ultra fine fiber started when its potential was assessed during research efforts into the common features of the high quality textiles among natural materials. After a technological breakthrough, the application was changed to make suede-like artificial leather. In so doing, the functions and fields of application were broadened. As a result of its research efforts in this area, Toray corporation has met with success in the market and other firms have also undertaken R&D to make ultra fine fiber. Another consequence of these efforts has been the advancement of the related technologies. Future R&D endeavours in this area are likely to be geared towards the needs of the market.
