Air-Jet Spinning
category
Air-jet spinning is a high-speed fasciated yarn production technology using compressed air vortices to wrap peripheral fibres around parallel core fibres, achieving 300-500 g/nozzle/hour production rates, 3-4× ring spinning productivity. Produces unique yarn structure with straight core and wrapped sheath, suitable for fine to medium counts (20-80 Ne), representing fastest-growing spinning technology (8-12% annual growth) capturing 5-8% of global staple yarn market.
Role
Bridges quality gap between ring and OE spinning, offering ring-like appearance and handle at OE-like productivity and costs, enabling premium fabric aesthetics in casual apparel, shirting, and technical textiles where productivity advantages justify investment in modern high-speed spinning technology representing future direction of staple yarn manufacturing.
