ABSTRACT:
Yarn hairiness is reduced by employing a vortex action of a fluid, such as air or steam. Yarn in a substantially dry condition is passed in a generally linear path through a body having a central through-extending generally linear passageway that is circular in cross-section. A plurality of bores are provided in the body which extend from the periphery of the body to intersect the central passageway, being tangentially disposed with respect to the central passageway. Fluid under pressure is introduced into the bores, and creates a vortex action which acts upon the yarn to twist and lay down protruding hairs that cause yarn hairiness. The bores are preferably disposed at an angle of about 40.degree.-50.degree. with respect to the central passageway, and are spaced along the length of the passageway. Shortly after the yarn exits the body, hot melt sizing is applied to it to maintain the protruding hairs in their laid down position.
