Abstract
An increase in rotor open-end spinning machine capacity and measures for a higher yarn spinning limit are always measured against the machine efficiency which is significantly affected by yarn breakages and their elimination. Yarn breakage frequency increases with an increase in rotor speed, reduced yarn twist and increasing yarn count. In the most unfavourable circumstances this can preclude an increase in the effective production rate or impair the yarn quality to an inadmissable extent. It is therefore important to investigate the demands on yarn strength resulting from sliver quality and rotor spinning parameters in relation to yarn breakage frequency. Studies on polyester rotor open-end-spun yarns are presented.
