While SCY has lessen Main publicity, generally less likely to result in top quality troubles in spinning and weaving, aside from uneven twists, on the other hand, its output performance is small. Thus, the price is more than RMB 5000/T higher than exactly the same schedule of ACY. The price of FDY is even more than RMB 10000/T higher than the same routine of ACY.
