Polyester–PTA Terminal products in synthetic fibers, polyester production; 85% in chemical fiber, polyester and 78%. Polyester including two products, a long wire, often as low-elastic yarn, production of various textiles; second, staple fiber, and cotton, wool, hemp and other blended, industry for the manufacture of tire cords, fishing nets, ropes, fabrics, edge of the vast materials. Polyester of production process under is after polyester slice links is divided into two species: second step spinning (and said slice spinning): oil–naphtha–on xylene (PX)–fine Terephthalic acid (PTA) + glycol (EG)–polyester slice (PET, including fiber slice, and bottle with slice, and film with slice)–polyester a step spinning (and said direct spinning): oil–naphtha–on xylene (PX)–fine Terephthalic acid (PTA) + glycol (EG)–polyester from production process in the visible: PTA and EG is polyester of upstream production raw materials, which PTA in formula in the accounted for 85%, is polyester of main raw materials. Two-step spinning after slicing intermediate products, back spinning the PTA for direct production of polyester. In 2005, China polyester production of 12.7 million tons, output of polyester slice of 5.14 million tons. Visible, most is the use of direct spinning polyester production process. As the industrial chain of the end product, polyester on the amount of PTA reaches a total of 70%. Therefore, PTA fluctuations directly affected the price of polyester production costs. Buy polyester production enterprises can take advantage of PTA futures hedge transactions, risk of to circumvent PTA prices. 1, and polyester industry total growth situation according to national statistical offices announced of data, 2006 1-June in China scale above polyester industry enterprise number for 590 home, the industry implementation industrial GDP 102.216 billion yuan, per cent increased 23.47%; assets total 154.8 billion yuan, per cent increased 18.41%; implementation sales income 100.575 billion yuan, per cent increased 23.42%; completed profit total 1.519 billion yuan, than over a year earlier over increased 1.042 billion yuan, per cent increased 218.59%; completed export delivery value 5.517 billion yuan, per cent increased 51.78%; industry overall employees number 203,400 people, per cent increased 2.25%. Thus, total pet industry growth look good. 2 generally, polyester short fiber polyester short fiber on the market into 3 categories: large chemical fiber, chemical fiber, low in fiber. Large chemical fiber: PET slice spinning or melt direct spinning of short fibers. Good color, batch number, strength and stability, small defects, good spinning. Chemical fiber: with a substandard PET slices or coupled with the PET back to metal spinning. Between the price of quality between dahua and small (mainly textile factories for and dahua blended to enhance the competitiveness of). Small chemical fiber: PET back to metal spinning. Price and quality parameters do not align, suitable for export to markets and areas for some quality requirements are not too high (such as fill material, and so on). In General, slice spun staple of basic had no defects, fiber weight even, smooth surface feel smooth, hand-pulled, slice spinning General strength is better, lot number, no color difference, physical indicators even. Small chemical fiber production in General, or was a staple for recycled raw material lot number smaller, similar algebraic feel no big chemical fiber is good (unless it is processed) defects, occasionally uneven weight, ultra-times the length of the general objective, general physical indicators to renewable do slightly worse. Under national statistical offices and China Customs of statistics data, in China 2006 1-June polyester short fiber yield for 2.9039 million tons, per cent increased 15.44%; 1-June import polyester short fiber 137,800 tons, export 137,000 tons, added resources (yield + import) 3.0417 million tons, net resources (added resources-export, is table view demand) 2.9047 million tons, display China polyester short fiber industry of market demand more strong. Compared with last month, import and export of polyester staple fiber industry in June 2006 production fluctuates, so that the current month added resources and net resources are changed. 3, and polyester long silk under national statistical offices and China Customs of statistics data, in China 2006 1-June polyester long silk yield for 4.694 million tons, per cent increased 15.39%; 1-June import polyester long silk 124,900 tons, export 192,200 tons, added resources (yield + import) 4.8189 million tons, net resources (added resources-export, is table view demand) 4.6267 million tons, display China polyester long silk industry of market demand more strong. National sales of polyester filaments are mainly concentrated in Zhejiang, Jiangsu, Guangdong and other areas, inflows are relatively less in other areas. In China 2006 1-July polyester fiber yield 8.9273 million tons, than over a year earlier over increased 14.1%; which yield maximum of provinces is Zhejiang Province, 1-July yield 4.101 million tons, for provinces leading; second is Jiangsu Province, yield 3.1102 million tons, ranked runner-up; and is Fujian province, yield 549,300 tons, was awarded third; Shanghai City 177,800 tons, for fourth; Shandong province 157,200 tons, accounted for fifth; Sichuan province 134,600 tons, ranked sixth; next is Guangdong Province 128,500 tons, for seventh; Henan province 127100 tons, accounted for eighth; Tianjin City 124,200 tons, ranked Nineth; Jiangxi province 76,500 tons, for tenth name; Liaoning province 60,900 tons, home 11th name; in Hainan Province 32400 tons, was awarded 12th name. Above 12 big cities 2006 total 8.7797 million tonnes 1, 98.35% per cent of national production of polyester fibers.
