What is yarn covering machine?
Yarn covering machine, Spandex yarn covering machine
Yarn covering machine (Spandex yarn covering machine) is able to produce both single covering and double-covering which feature an extremely high performance and works to have the yarns of different natures as the cored wires, such as spandex, low stretch yarn, elastic ribbon, filament, metallic yarns and LVREX high stretch yarn; and have cotton yarn, synthetic fiber, polyamide, polyester, real silk and metallic yarns as the covering yarns.
The air yarn covering machine has the following functions: it feeds continuous fibers such as polyurethane yarn, generally known as spandex, nylon and polyester, into an interlacing nozzle with a feed roller set at arbitrary speed, interlaces that yarn with air using turbulence generated by compressed air inside the nozzle, and then produces yarn known as ACY.
The JINGGONG Yarn covering machine can produce ACY at lower cost by processing it at a higher speed when compared to SCY which is produced by traditional low speed winding covering machine.
From a current global perspective, use of ACY is dramatically increasing. And that is because ACY has been recognized as a worthy substitute for SCY because of the improved quality. This trend will accelerate in the global market trend and decreasing price of the product.
ACY was originally used in panty hose (specifically the panty area), leg tights, socks, inner gloves, etc. However, as the price of polyurethane yarn as a material has recently been declining, application of ACY in apparel such as sportswear, outerwear and inner wear is increasing.
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.
