Derun create ACY from POY and spandex directly. Our products can perform attract texturing and air covering in a single action, give a far better yarn evenness and toughness.
The elongation from the SCY is likewise largely determined by the performance with the spandex core yarn twisting too much, the outer layer of fibre wrapped much too carefully, and also the elastic outcome in the spandex yarn can’t give a great general performance so the elongation decreases.
