In the event the schedule spandex yarn is pre-drawn three.5 moments, the creep resistance is best. It ought to be specifically modified in accordance with the usage tone plus the type of its downstream material.
As well as the spandex stretch prerequisite in ACY, SCY has Yet another important course of action parameter would be the twist. Twist can make a variance in top quality, elongation and evenness.
