According to different equipment, it can be divided into two types: mechanical covered yarn and air covered yarn.

ACY
ACY is a yarn that draws the outer fiber filament and spandex filament through a certain type of nozzle at the same time, and is regularly sprayed with highly compressed air to form rhythmic network points. Its fabric feels soft and smooth.

Nylon air covered yarn can be used as woven fabric, and double twisted yarn can be processed into single yarn or replaced with single yarn,ang panapton maayo nga gibati ug mahimong magpakita sa mga bentaha sa coating.

polyester air covered yarn not only has the characteristics of wrapped polyester, but also has the good elasticity and recovery performance of spandex, which makes up for the defect of single component filament.

SULOD
Spandex covered yarn is an elastic composite yarn formed by taking spandex filament with a certain drafting multiple as the core and wrapping the polyester filament spirally outside the core filament through the covering process. The composite yarn not only has the characteristics of wrapped polyester, but also has the good elasticity and recovery performance of spandex, which makes up for the defect of single component filament.
Spandex covered yarn has the advantages of anti wrinkle, easy washing and quick drying. At the same time, it can give play to the advantages of outsourcing fiber DTY, good moisture absorption, less static electricity and not easy to pilling.Spandex mechanical covered yarn (SCY) is the continuous rotation of the filament and wrapped around the filament spun yarn, which is twisted and twisted (TPM) , Fabric style flat and crisp is its main features.

Ang yarn nga natabonan sa hangin ug ang yarn nga gitabonan sa mekanikal adunay kaugalingong mga bentaha ug mga disbentaha sa downstream weaving mill. Ang hilo nga natabonan sa hangin kasagarang nagkinahanglan og gidak-on sa dihang mag-warping sa usa ka air-jet loom, kon dili ang tela daling mapulpog ug mabali nga mga hilo, apan mahimo kining gamiton direkta pinaagi sa pagbunal. Sa mga termino sa gasto lamang, ang kapasidad sa produksiyon sa hilo nga gitabonan sa hangin mas taas kay sa hilo nga gitabonan sa mekanikal, nga naghimo sa presyo nga mas ubos kaysa sa bag sa makina, nga sayon sa pagpakunhod sa gasto sa downstream weaving mill.
Although the mechanical covered yarn does not expose the core filament, generally except for the uneven twist, it is not easy to cause quality problems during spinning and weaving, but the output is low, so the price is higher than the air-covered yarn of the same specification by more than rmb 5000/t. The price of denier covered yarn is even higher than that of air-covered yarn of the same specification, which is more than rmb 10000/t, thus greatly increasing the cost of using mechanical covered yarn.
The scope of application of spandex covered yarn
Spandex covered yarn can be used to make socks, wrist guards, leg guards, finger covers, knee pads, lining cloth, labor protection gloves, masks and other products,with a wide range of applications.It is suitable for weaving sports tights, such as swimming suit, ski suit, women's underwear,etc. According to the use of covered yarn, select appropriate core yarn and outer yarn, and its strength is higher than any single yarn.
