Yarn texturing air jet with cylindrical and planar baffles

摘要

The air jet is provided with a first cylindrical baffle (A) and a second planar baffle (B) supported adjacent the exit orifice (30) of the air jet for successive engagement by the yarn (Y) leaving the air jet. The baffles (A) and (B) successively engage and deflect the yarn as well as the air leaving the exit orifice of the air jet so that two different types of treatment are imparted to the yarn by the successive baffles to permit higher operating speeds and to enhance the quality of the textured yarn. The homogeneous quality of the yarn is enhanced and the yarn exhibits a tighter yarn cross-section bundle because the exterior loop surface and the number of periodic balloons are both reduced.
