Practical Aspects of Drafting Tenacity of Cotton at the Ring Spinning Frame

Abstract

Drafting tenacity was measured at the front draft zone of double-apron drafting system used in cotton spinning. The results show the relationship between drafting tenacity and fiber length and micronaire, fiber bundle tenacity, fiber parallelization at the front draft rolls, fly liberated at the ring frame, and tenacity-to-break of the spun yarn. Generally, good correlations were found between these factors and drafting tenacity.
