The synthetic fiber manufacturing industry is the largest-scale and most-branched sub-industry in the chemical fiber industry, and products of the synthetic fiber manufacturing industry comprise acrylic fibers, chinlon, spandex and the like besides polyester. In 2005, the yield of Chinese chemical fibers is 1629 ten thousand tons, which accounts for 37% of 4400 ten thousand tons of the world total yield. The synthetic fiber yield accounts for 92% of the total amount of the chemical fibers, and the polyester fibers account for 85% of the synthetic fibers. The terylene is divided into filaments and staple fibers, wherein the filaments account for about 62 percent, and the staple fibers account for about 38 percent. There are two methods for producing filaments and staple fibers: firstly, PTA and MEG are produced into slices, and the slices are melted and then are spun to form the fiber spinning material; one is that PTA and MEG are produced by direct spinning without slicing in the production process.
