Abstract
Herein disclosed is a spinning frame of vortex flow type, which is composed mainly of a roller draft unit, a pneumatic false twisting unit and a take-up unit. A pneumatic tube having a rectangular cross-section is interposed between the roller draft unit and the pneumatic false twisting unit so that many floating fibers to be fasciated may be generated to make a fasciated spun yarn which has high strength and excellent quality.
