What is single covered yarn? what are the features?

Single covered yarn is part of the conventional covered yarn, which is also referred to as traditional covered yarn. 

In this process, spandex/elastane is drawn at a certain rate. Techanically speaking, the rate is called draft.  Spandex is fed at a constant speed and then covered with hard yarn (polyester or nylon). Its characteristics, in particular elongation and elasticity depends on machine parameter of the draft as well as on the twist per metre and the hard yarn. 

Since it combines two types of yarn, covered yarn enjoys the characteristics of outer yarn and core yarn simultanesously. Usually the knitting performance, handfeel, dyeing effect and final elasticity are the main parameters for the product.
