The bobbin is set into a rotating shaft referred to as a spindle.
Polyurethane elastic fibers are passed through the hole of the spindle from the downward direction, and the polyurethane elastic fibers are twisted in the right direction (Z) and the left direction (S) to the core, respectively.
This is referred to as "covering" since the yarn which was wounded quantitatively in the process of "bobbin winding" wraps the core yarn like a sheath.
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.
