airtextured

Airtextured, usually written as air-textured yarn and abbreviated ATY, is a bulked yarn produced by air-texturing processes that use high-velocity air to entangle filaments into a looped, crimped structure. The technique is a form of texturing used with synthetic filament yarns to increase cover, elasticity, and warmth without adding significant weight.

Production involves a texturing machine that draws filaments through a nozzle or air jet, where the air flow twists and entangles the filaments, forming random loops. The resulting yarn has increased volume and a uniform, soft hand. Bulk can be adjusted by air pressure, throughput, and filament composition. The yarn is continuous and can be produced in various deniers.

Materials and uses: nylon and polyester are common; other synthetic filaments may be used. ATY is widely used for hosiery, knitwear, activewear, and upholstery where bulk, elasticity, and warmth are beneficial. It is typically sold as ATY or under brand or market names for air-textured yarns.

Compared with other texturing methods such as false twist or draw-texturing, air-texturing offers a different balance of bulk, hand, and performance. The choice of polymer and processing settings influences the final feel and characteristics, and equipment maintenance and energy use are practical considerations in production.
