ABSTRACT:
A method and apparatus for texturing continuous filament yarn wherein the yarn is fed at a controlled rate and under controlled tension into a confined crimping zone against a mass of crimped yarn therein causing the yarn to collapse longitudinally forming crimps which become part of such mass. Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps. The crimped yarn mass is then fed at a controlled rate from the crimping zone into a setting zone. Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps. The pressure applied to the yarn mass in the setting zone is substantially only sufficient to keep the crimps closed during the final setting thereof. The crimped yarn mass is then fed from the setting zone into a cooling zone. The yarn mass is cooled in the cooling zone to a temperature below that at which the yarn undergoes any molecular structural alteration in the absence of the application of a substantial force thereto. Finally, the yarn is withdrawn at a controlled rate from the cooling zone in continuous filament form.
