Abstract: A method for producing a novel teased yarn having teased, hairy, fluffy, fuzzed character without loops resembling angora, alpaca and the like yarns from multifiber spun yarns of short to medium staple, wherein the yarn supplied has a yarn twist in a predetermined twist direction and is fed along a feed path through a yarn feed bore of a jet nozzle member to a fluid vortex station and turbulence chamber station defined within a surrounding housing.

Abstract: An apparatus for producing a novel teased yarn having teased, hairy, fluffy, fuzzed character without loops resembling angora, alpaca and the like yarns from multifiber spun yarns of short to medium staple, and the resulting yarn produced thereby, wherein the yarn supplied has a yarn twist in a predetermined twist direction and is fed along a feed path through a yarn feed bore to a fluid vortex station and turbulence chamber station defined within a surrounding housing.

Abstract: An apparatus for interlacing or entangling continuous multifilament synthetic yarn wherein the yarn to be interlaced is fed along a feed path through a yarn feed bore to a jet nozzle member defining with a surrounding housing and an outlet tube member a shaped turbulence chamber within the housing at the exit of the yarn feed bore in the nozzle member. The jet nozzle member has one or more jet passages directing fluid from a pressurized air chamber into the turbulence chamber along jet axes inclined to the yarn feed axis and offset sidewise in nonintersecting relation thereto to produce interlocking entanglements of filaments of the yarn during passage therethrough.

Abstract: A method and apparatus for texturing continuous filament yarn wherein the yarn is fed at a controlled rate and under controlled tension by a pair of feed rolls into a confined crimping zone against a mass of crimped yarn therein, causing the yarn to collapse longitudinally to form 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 by means of toothed rolls 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 yarn mass is moved through the setting zone by an endless belt having upstanding teeth that positively engage the yarn mass. The pressure applied to the yarn mass in the setting zone is substantially sufficient only 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.
