ABSTRACT:
Jet using high pressured gaseous fluid to partially fracture yarn and to entangle the yarn, the jet being a significant improvement over the jet disclosed in the Dyer patent, U.S. 2,924,868, which has a housing provided with a gas inlet, a yarn guiding needle, orifice plate, and venturi; the improvement including reducing the size of the passageways through the needle, orifice plate and venturi, and selectively providing the inward taper of the outer wall of the yarn guiding needle inner end portion with a half angle of about 15.degree. relative to the axis of the needle yarn guiding passageway, providing the wall of the orifice plate entry opening with an inwardly tapering bevel of about 30.degree. relative to the axis of the entry opening, and providing the diverging wall portion of the venturi exit opening with a half angle of about 2.5.degree. relative to the venturi axis.
