Abstract
Fifty-six bales of medium staple cotton were spun into 40s yarn to evaluate spinning performance. In a parallel effort, roving samples from each bale were tested on a single-end drafting tester that duplicates the Tru-Set drafting system used in spinning. Front-zone drafting force and force-vari ability measurements were related to fiber properties and spinning performance. Drafting-force variability correlated well with spinning. The correlation with spinning was improved by subtracting from drafting-force variance the weight variance caused by fiber randomization due to average micro naire fineness.
