Abstract: A rotatable cleaning element having a resilient, porous material disposed on the outer surface thereof is mounted in a foil bearing so that the surface of the porous material protrudes above the bearing surface. The interior of the bearing is maintained at a negative pressure, and a jet of pressurized air disposed within the rotatable element.

Abstract: Yarn is treated in an air entangling apparatus having a yarn passageway through which one or more multifilament yarns are fed and an air inlet duct intercepting the bottom of said passageway at right angles, the longitudinal axis of the inlet duct passing through or close to the longitudinal axis of the yarn passageway. A jet of air is introduced into said passageway and strikes the upper wall thereof forming a plural vortex turbulent zone in the upper portion of the yarn passageway which entangles the multifilament yarns. An air outlet duct intercepts the top of the yarn passageway and serves to create an air flow which holds the yarn in the upper portion of the passageway. Yarn is fed into the passageway with a small degree of overfeed, generally from about 0.1 to 10%. A structure, such as a rod, extends into the yarn passageway and contacts the yarn fed therethrough. The resistance to yarn movement resulting from this contact creates yarn slack in the area of the turbulent zone.

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.
