ACY (Air Covered Yarn) is an innovative textile material that combines elastic yarn with core fibers using air cover technology, which is light, soft and comfortable. This yarn is not only widely used in clothing, underwear and sportswear, but is also popular for its durability and versatility. The core fiber of ACY yarn protects the natural softness of the outer yarn, while improving the breathability and fluffiness of the fabric, avoiding possible damage from mechanical wrapping. The production process of ACY yarn focuses on environmental protection, complies with international environmental certification standards, and ensures the sustainability and safety of products. Our ACY yarns are available in white and black color options and are suitable for the production of a wide range of textiles, including woven and knitted fabrics.
Air Covered Yarn (ACY) utilizes high-pressure air jet technology to intermingle spandex core with textured polyester filaments, creating a yarn with exceptional elasticity and smooth surface. This advanced process eliminates traditional twisting, resulting in torque-free performance and superior fabric stability. The air covering method ensures uniform filament distribution, producing fabrics with outstanding stretch recovery, soft hand feel, and excellent dimensional stability. ACY is the preferred choice for high-performance apparel where comfort, fit, and durability are paramount.
Superior stretch and recovery properties ensure fabrics maintain shape after repeated use and washing cycles.
Air covering eliminates twist, reducing fabric skewing and spiraling issues during processing.
Consistent filament coverage delivers smooth, uniform fabric surface without core exposure.
High-speed air covering technology enables efficient manufacturing for large volume orders.
ACY uses high-pressure air to intermingle filaments instead of twist, delivering lower torque, better softness, and higher production efficiency with uniform coverage.
Maximum 40°C washing temperature is recommended to preserve elastane elasticity and prevent premature relaxation of the spandex core.
Yes, ACY performs well in warp knitting with appropriate tension settings. Lower yarn tension helps avoid over-stretching the spandex core.
The air covering process creates micro-voids in the yarn structure, enhancing moisture wicking and breathability of finished fabrics.
