Process for producing fluid jet teased, fluffy, hairy yarns from

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. The jet nozzle member has a jet vortex generating jet passage opening into the yarn feed bore immediately upstream of the turbulence chamber station directing fluid from a pressurized air chamber into the yarn feed bore in a direction to produce a vortex in a direction opposite the predetermined twist direction of the yarn to exert forces tending to open up the fibers of the spun yarn, and the jet nozzle member additionally includes a plurality of turbulance producing jet passages opening into a turbulence chamber immediately downstream from the fluid vortex station to further open and disarrange the fibers to produce the teased yarn effect.
