PHOTOSENSITIVE SYNTHETIC FIBER

摘要

PURPOSE:To obtain the titled fibers, containing graphite, capable of shrinking or melting by irradiation with near infrared rays and level dyeing even by blending with ordinary synthetic fibers without impairing physical properties. CONSTITUTION:For example, preferably 0.01-0.1wt.% graphite having preferably <=0.1mu average particle size is added to a raw material resin for thermoplastic synthetic fibers and the resultant blend is melt spun to afford the aimed fibers. Furthermore, the above-mentioned fibers can be partially used as textile products and partially shrunk or melted by irradiation with near infrared rays to form uneven patterns and produce bonding effects.
