This study discusses the evaluation of stretch-breaking force and its CV% in the tow-to-
yarn direct spinning with 12k oxidized filament tow. We aimed to describe a new method for
determining suitable draft conditions in the direct spinning to obtain the best oxidized yarn
quality. To correlate the stretch-breaking force and the yarn quality, oxidized direct spun
yarns were spun on a modified laboratory spinning frame for one-step conversion of a tow-
to-yarn system. Base on the correlation of stretch-breaking force CV and direct oxidized
yarn quality, the drafting ratio and roller gauge corresponding to the lower unevenness
(CV%) of the direct oxidized yarn could be chosen as the suitable draft condition in direct
yarn spinning to obtain the best oxidized yarn quality. Obviously, the results revealed that
the technique of stretch-breaking force could be applied on the optimum draft condition of
tow-to-yarn direct spinning.
