Spandex Yarn Covering Machine, Air Jet Covering Machine

Covering machine: (Spandex covered yarn)

Spandex covered yarn is an elastic yarn formed by using spandex yarn as the core and wrapping the stretched spandex yarn in a spiral manner with filament or short fiber yarn.

According to the number of covering layers, the spandex covered yarn can be divided into single covering and double covering.

The single-covered yarn is a layer of outer silk (yarn) wrapped on the outer layer of the core silk spandex. Mainly used for elastic fabrics such as socks and weft knitted underwear.

Double-covered yarn is to cover two layers of filaments or yarns on the outer layer of the spandex core wire, and the two layers of covering are generally in opposite directions. The core filament spandex is well covered, and the exposed phenomenon is relatively light, and because the outer filament wraps the core filament symmetrically with opposite helix angles, the elastic force of the wrapped filament is well balanced, and the subsequent process can generally be carried out without shaping treatment. processing, but the processing cost of double-covered yarn is higher. Mainly used for elastic fabrics such as leggings, elastic belts, sock openings, pantyhose and so on. For fabrics requiring high elasticity, and partly for woven fabrics. The fabric woven with covered yarn is thicker, especially suitable for weaving sports tights, such as swimming suits, ski suits, etc.
