Air Jet Spun Yarn Mechanics in Elastic Woven Fabrics
Air jet core-spun yarns deliver torque-free, pill-resistant elastic wovens by locking polyurethane filaments inside parallel staple cores bound by vortex wrappers.
Air Jet Core Spun Yarn
Production Architecture
Composite textile structure formed by wrapping a staple fiber sheath around a continuous filament center using compressed air. Air jet core spun yarn utilizes high pressure vortices to entangle surface fibers while the central filament remains under tension. This arrangement prevents the core from migrating to the surface during subsequent knitting or manufacturing stages.
Structural Integrity
Mechanical stability depends on the pressure of the air nozzles and the delivery speed of the drafting system. If the air pressure is too low, the wrapper fibers do not grip the core sufficiently. High speed production often results in a leaner profile compared to ring spun alternatives.
Surface Characteristic
Rougher textures are common because the wrapper fibers lie at varying angles across the axis. Unlike traditional spinning, air jet core spun yarn exhibits a lack of true twist in the central core. This arrangement allows for higher production speeds.
Industrial Application
Strength and comfort meet in workwear where durability is required alongside a natural fiber touch. Because the core provides dimensional stability, the fabric resists stretching out of shape over repeated laundry cycles. High durability requirements in uniform manufacturing make this construction a standard choice for garment producers who require consistent shade and performance across large production lots.
