Air Covered Yarn is a regular intermingled yarn, the covering filament yarn and Spandex are drawn meanwhile from a special jet nozzle where the yarns are air-jetted at regular intervals by high compressed air.
The Air-jet Covered Yarn needs sizing for warp knitting and can be used for weft knitting directly. The production efficiency of Air-Covered Yarn is much higher than Conventional Covered Yarn (also known as SCY – Single Covered Yarn or DCY – Double Covered Yarn) and the price is also much lower, which would reduce much cost for downstream textile company.
