three. The core yarn of Main spun yarn is wrapped exterior from the staple fibre, you can’t begin to see the corn yarn with a nicely-wrapped Main spun yarn.
The phenomenon of deformation with time under the action of a constant draft force is known as creep. When the schedule spandex yarn is pre-drawn 3.5 occasions, the creep resistance is very best. It should be particularly adjusted according to the usage tone and also the kind of its downstream fabric.
