Elastane Yarn Interlacing and Composite Yarn Production
topic
Elastane and synthetic filament composite yarn production by air jet entanglement feeds pre-stretched elastane at high overfeed through an interlacing nozzle together with polyester or nylon filament yarn, creating entanglement nodes that bind the elastane within the synthetic yarn structure to produce a composite stretch yarn without the yarn wrapping operations of covered elastic yarn production, achieving stretch recovery with reduced machine and processing complexity.
Role
Produces composite stretch yarns incorporating elastane through air entanglement at lower production cost than conventional covered elastane yarn production, enabling stretch fabric production for sportswear and active wear applications where the combination of synthetic yarn aesthetics with elastane stretch is required and where the air-entangled composite construction provides adequate performance at lower manufacturing complexity than fully wrapped covered elastane alternatives.
