Socks covered lycra yarn

The covered yarn is made of pre-stretched spandex elastic yarn through the center of the hollow spindle to become the core wire. The yarn or filament on the spindle is wound on the spandex evenly and spirally as the outer covering yarn, and then synchronously crimped. Spandex covered yarn has the characteristics of elastic elongation (300%-400%), stiff hand, thick yarn count and high strength. Covered yarn is the most commonly used variety of spandex processed yarn, accounting for about 65% of the entire processed yarn type. The outer yarn is mostly polyester, nylon or cotton yarn, and polypropylene is also used as the outer yarn.
