The double-covered yarn has two outer layers of filaments or yarns wrapped across the spandex core, and both of these levels are generally in opposite directions. The core spandex is covered to a superb extent as well as core exposure is significantly less, and because the outer wrapped filaments are wrapped with reverse spiral angles symmetrically round the Main filaments, the elasticity of the wrapped yarn is nicely balanced and may normally be processed from the afterwards system with no shaping therapy, nevertheless the processing price of double wrapped yarn is increased.

Covered yarn is spandex wrapped using a chemical filament fibre, likewise, a Main yarn of spandex and outer non-elastic staple fibre or filament spiral-wrapped into the elongated spandex to variety the elastic yarn. It could hold the Main exposed less than stress.
if the twist is too small, the outer covering fibre can be free and impact the masking impact, which can trigger the Main exposure, so the twist should be superior in mechanical wrapping. However, when the twist is just too high, The material feels stiff and drapes poorly.

When referring to covered yarn, 1 talks basically about elastane yarns which have at the least yet another yarn wrapped around. Masking nonetheless isn't completely placed on elastane, occasionally also fine wires are covered.
