As well as the spandex stretch necessity in ACY, SCY has another vital course of action parameter may be the twist. Twist can make a change in good quality, elongation and evenness. Boost the twist to lift the pressure of holding involving the outer covering fibre as well as spandex yarn, generating the covering yarn more robust.
Though SCY has reduce core exposure, commonly not as likely to cause high quality difficulties in spinning and weaving, apart from uneven twists, on the other hand, its output efficiency is reduced. Hence, the value is a lot more than RMB 5000/T better than a similar plan of ACY. The cost of FDY is far more than RMB 10000/T higher than the same routine of ACY. Consequently it significantly raises the cost of utilizing the SCY.
ACY and SCY have their advantages and disadvantages in downstream weaving factories. In the event the ACY warps to the air jet loom, normally want sizing, or else The material is a snap to lint, split and so on, but weft is can directing use.
