According to the number of coating layers, spandex covered yarn can be divided into single coating and double coating. The difference lies in the number of layers and wrapping degree of outer covering wire.
Single covered yarn is wrapped with a layer of outer wrapped yarn on the outer layer of core wire spandex. The number of turns is small, and the exposed core of the fabric is obvious, so it is not suitable for dark products. It is mainly used for elastic fabrics such as socks and weft knitted underwear.
Double covered yarn is covered with two layers of filament or yarn on the outer layer of spandex core wire, which are generally in the opposite direction. The core filament spandex is well covered, and the bare phenomenon is relatively light. Because the outer wrapping filament is symmetrically wrapped around the core filament with the opposite spiral angle, the elastic balance of the wrapped filament is good. Generally, the subsequent process can be processed without setting treatment, but the processing cost of double covered yarn is high. It is mainly used for elastic fabrics such as leg guards, elastic belts, sock openings, panties and so on.
