For example, in
October 7, 2010 - November 7 to 30 days, Zheng sugar futures contract rose 30.1%; Shanghai zinc futures contracts rose more than 20%; November 29 to December
31, 30 days, LME copper contract was up 17.68% main; main copper contract rose 17.76% in the December 30 exceeded 70,000 yuan / ton mark and continue to
implement, January 4 this year hit a record high of 71,160 yuan / ton, Then basically the oscillation between 70,000 ~ 71,000 yuan, Chinese New Year and then

Both futures price change after the Spring Festival has remained the same pace, remained a high oscillation slight trend. But obviously you can see, since
October 2010 since the two PTA futures prices rose significantly faster in Zhengzhou cotton futures price by the rapid rise in the driving, PTA futures
prices have risen significantly less than the increase in Zhengzhou cotton futures, recently a far more dramatic. 3. Demand is still relatively strong
chemical and raw material prices round the fundamentals since the second half of 2009, textile and chemical fiber industry has shown a rapid recovery after
the financial crisis of growth, the market works well, good economic returns. Which increased by 14% chemical fiber production, chemical industry, mainly
downstream of several varieties of production are rapid growth, such as yarn production in 2010 increased 13.74%, 13.38% increase which yarn, synthetic yarn
up 22.88%; chemical fiber cloth production increased by 15.11% , tire cord fabric production increased by 22.35%, non-woven production increased by 24.23%.
Market recovery after the financial crisis, demand growth is, chemical products and raw materials prices were rising rapidly.
Meanwhile, in 2010 the industry 
has also brought economic benefits of good investment growth. As of the end of 2010, several domestic and foreign equipment manufacturers of major chemical
fiber spinning machine orders are routed to the basic end of 2014. Good for the future of this industry is expected to push up the demand for the current
price of raw materials is one important factor. Chemical companies failed to profit from rising prices of the recent sharp rise in the domestic chemical
fiber and chemical fiber enterprises did not bring much to the domestic benefits of the current round of market is completely cost-push price, raw material
prices rose significantly greater than the chemical products increase, while prices in the chemical fiber, chemical fiber enterprises emerged rapidly
shrinking profits, some even losing money. Figure 3 polyester staple fiber and polyester POY processing gross margin trend point of view, at current prices,
the recent price increases have been the main raw material for polyester production of some enterprises close to breakeven, individual companies have a loss.
