Although SCY has decrease Main publicity, usually more unlikely to bring about high quality difficulties in spinning and weaving, except for uneven twists, however, its generation efficiency is small. As a result, the price is greater than RMB 5000/T better than precisely the same routine of ACY. The price of FDY is more than RMB 10000/T greater than precisely the same schedule of ACY. Hence it tremendously improves the cost of utilizing the SCY.
