ABSTRACT:
A fasciated yarn is produced that is suitable for making apparel fabric from predominantly non-thermoplastic staple fibers, and which approaches ring spun yarn in properties and appearance but can be produced much more quickly and simply. The fasciated yarn comprises vacuum spun yarn consisting of fibers including core fibers and wrapper fibers, the wrapper fibers being predominantly individual fibers although having some groups of wrapper fibers. The groups of wrapper fibers appear as non-uniform, non-consistent groupings and provide a relatively smooth appearance. The wrapper fibers are wrapped at a helix angle of about 30.degree. (e.g. about 30.degree.-50.degree.), and about 20-30 percent of the fiber mass comprises the wrapper fibers. The wrappers are essentially devoid of auger or corkscrew appearance. The core fibers are essentially parallel staple fibers. The wrapped and core fibers have the same dyeability. Vacuum spun yarn has a break strength comparable to a break strength of at least 500 grams break strength for a yarn produced from approximately 1/18's count fibers of 55 percent polyester and 45 percent wool, or at least 175 grams for 100 percent wool.
