In the paper the new technology of solospun and its principle of spinning are introduced. The yarn produced in this method is better than the normal yarn with the same count. This kind of yarn has the high strength and the characteristics of high resistant to abrasion and less hairiness etc. It can improve the efficiency of single strand to weave as well as provide the advantageous conditions for developing high count, light and thin product. Technology of solospun has wide prospect for development and application.
