ABSTRACT:
A method is disclosed for producing polyester fibers having uniform primary and secondary crimps. The method includes the steps of advancing fibers into a stuffer box having an upper doctor blade and a lower doctor blade, positioning the upper doctor blade and the lower doctor blade such that the doctor blade gap is broad enough to permit the formation of secondary crimps and yet is narrow enough to maintain primary and secondary crimp uniformity, and then applying a longitudinal force against the advancing fibers to impart uniform primary and secondary crimps.
