Abstract
Methods and apparatus are provided to make composite yarns having a filamentary core with at least one elastic performance filament and at least one inelastic control filament. A fibrous sheath, preferably formed from spun staple fibers, surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament most preferably includes a spandex and/or a lastol filament. The at least one inelastic control filament is most preferably formed of a textured polymer or copolymer of a polyamide, a polyester, a polyolefin and mixtures thereof. Preferably, the fibrous sheath is formed of synthetic and/or natural staple fibers, most preferably staple cotton fibers. The elastic composite fibers find particular utility as a component part of a woven textile fabric, especially as a stretch denim fabric, which exhibits advantageous elastic recovery of at least about 95.0% (ASTM D3107).
