  • Polyester fiber tow having substantially uniform primary and secondary crimps
    Patent number: 6706393
    Abstract: Disclosed is a polyester fiber tow formed of polyester fibers having uniform primary and secondary crimps. The uniformly crimped polyester fibers possess excellent strength characteristics. Also disclosed is a method for producing such uniformly crimped polyester fibers.
    Type: Grant

  • Polyester fibers having substantially uniform primary and secondary crimps
    Patent number: 6572966
    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. The polyester fibers crimped according to the disclosed method have substantially uniform primary and secondary crimps, and are further characterized by tensile factor that is about the same as the tensile factor possessed by an otherwise identical uncrimped polyester fiber.

  • Method of producing improved crimped polyester fibers
    Patent number: 6134758
    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.
