Composite yarns (10) have a filamentary core (10-1) provided with at least one elastic performance filament (12) and at least one inelastic control filament (14). A fibrous sheath (10-2) formed from spun staple fibers (16) surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament (12) includes a spandex and/or a lastol filament. The at least one inelastic control filament (14) is formed of a polymer or copolymer of polyester. Preferably, the fibrous sheath (10-2) is formed of synthetic and/or natural staple fibers (16), most preferably 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).
