Air Jet Spinning

Air-Jet Spinning, Yarn / / / Leave a Comment

Air jet spinning has offered yarn manufacturers the opportunity to produce yarn at relatively high production rate. Unlike other spinning methods in which productivity is limited by the amount of twist in the yarn, Air Jet yarns can be produced at the same production rate regardless of yarn counts. Murata Vortex Spinners are one such leading Air Jet spinning machines which excel at producing finer yarns (Ne 40/1-60/1), because of the improved strength imparted to the smaller fibre bundle.
