Abstract
A process for forming a continuous filament yarn having the surface tactile character of a spun yarn. The process includes passing the cohesive yarn structure through the interior of a rotating sleeve member disposed in surrounding relation to the cohesive yarn structure. The rotating sleeve member includes an abrasive inner surface of diameter greater than the cohesive yarn structure and is adapted to contact the exterior surface of the cohesive yarn structure such that at least a portion of the elongate filaments disposed at the exterior of the cohesive yarn structure are broken. Terminal ends of the broken filaments define an arrangement of outwardly projecting hairs at discrete locations disposed substantially around the circumference of the cohesive yarn structure. An apparatus for carrying out the process is also provided.
