By rising the spandex extend, The proportion articles of spandex yarns will lower and trigger a significant degree of curl within the wrapped fibres. Nevertheless, in the event the degree of stretch is simply too massive, the spandex yarn deformation amplitude is near the critical price of deformation. It is going to decrease the covered yarn's power but is conducive on the covered yarn's uniformity.
The compressed air sorts rhythmic network points, causing a material that feels exceptionally soft and smooth.
once the twist is too very low, the outer covering fibre is usually free and impact the masking effect, which may cause the core publicity, And so the twist ought to be substantial in mechanical wrapping.
