Core-Spun Fancy Yarns

Core-spun fancy yarns: incorporating continuous filament core (elastic, strong, or decorative) with staple fiber sheath via modified ring spinning. Types: (1) Elastic core-spun (spandex core 100-400 denier covered with cotton, polyester, nylon staple—stretch denim, athleisure, 30-40% of core-spun market), (2) Metallic core-spun (metallic filament core wrapped with staple for sparkle without metallic surface—evening wear, socks), (3) Siro-spun fancy (two rovings one with effect fibers twisted together creating integrated fancy effect), and (4) High-tenacity core-spun (polyester/nylon filament core improving strength 30-50% for technical textiles, sewing threads). Production: specialized ring spinning with core feeding system introducing filament just before twisting point, staple wraps around core. Applications: stretch fabrics (denim, activewear), decorative textiles, high-performance threads, and technical textiles requiring specific core properties.
