The decision depends on several factors. A rectangular can with 450 diameter and 1200 mm height holds approx. 15 kg cotton sliver.
The capacity of a rectangular can is almost twice as high with 27 kg of cotton sliver. Another advantage of rectangular cans is the easier implementation of an automatic can transport system.
Today, draw frames are no longer required in rotor spinning. This applies to all materials and yarn counts. The applications range from processing of reclaimed fibers to fine yarns.
In the meantime, more than 2,500 Truetzschler IDF are operating in rotor spinning mills throughout the world. The combination of improved yarn quality coupled with significant savings is convincing.
