The phenomenon of deformation with time underneath the action of a continuing draft force is referred to as creep. If the schedule spandex yarn is pre-drawn three.5 situations, the creep resistance is ideal. It should be specially modified in accordance with the utilization tone and the form of its downstream fabric.
There are 2 functions of masking a yarn: one particular requirements an elasticity which regular textile yarn cannot provide even though one particular would nonetheless like to maintain the apperance from the textile yarn.
However SCY has lessen core publicity, usually more unlikely to bring about high-quality issues in spinning and weaving, apart from uneven twists, even so, its output performance is reduced. Hence, the value is in excess of RMB 5000/T bigger than the same schedule of ACY. The price of FDY is much more than RMB 10000/T larger than the identical regimen of ACY.
