摘要： Microfibers have been manufactured from dissolved cellulose, from which threads, yarns, and fabrics can be made. These cellulosic microfibers may be used to produce fabrics with the very soft feel that is characteristic of microfiber fabrics, and the water absorbency and comfort of cellulosic fabrics. Furthermore, since the microfiber diameter may be 2 &mgr;m or smaller (about the same size as dust particles and small oily droplets), these fabrics have an exceptional ability to remove dust and oil droplets from surfaces and gas streams, and are therefore useful in filter media. The novel microfibers may be manufactured by the continuous flow of dissolved cellulose through a converging die. Imposing orientation in the incipient microfiber prior to or during crystallization of the cellulose produces continuous fibers of substantial aspect ratio, without significant entanglement.
