Nevertheless SCY has lower core exposure, usually less likely to result in good quality troubles in spinning and weaving, apart from uneven twists, nonetheless, its manufacturing efficiency is low. So, the worth is in excess of RMB 5000/T larger than the identical routine of ACY. The cost of FDY is a lot more than RMB 10000/T greater than a similar regime of ACY. As a result it greatly boosts the cost of using the SCY.
The upper the spandex extend is, the higher the power and elongation of ACY.
