The compressed air types rhythmic community factors, leading to a fabric that feels exceptionally tender and clean.
once the twist is simply too minimal, the outer masking fibre is often free and affect the covering effect, which may cause the core publicity, Therefore the twist need to be large in mechanical wrapping. Having said that, once the twist is simply too higher, The material feels rigid and drapes badly.

1 is outer covering, and another is inner covering. So the Spandex is double covered with yarn and last yarn has zero torque. The various TPM and DR make numerous senses of ease and comfort touch and extension.
