Polyester staple fiber and viscose staple fiber are used as textile raw materials. The market trend is affected by downstream textile purchase demand, and also by the combination of upstream raw material price fluctuation and capacity adjustment. Therefore, the trend is independent. Just as the current July-August is the traditional low season of textiles, although the depreciation of the renminbi will block some of the imported yarns abroad, the overall downstream demand is relatively insufficient, and does not support a sharp rise in raw materials. However, the trend of several raw materials has been divided.

Polyester staple fiber was supported by the strong rise of crude oil and PTA. Since mid-July, the quotation has been reported continuously, and the actual transaction volume has also risen, with a rise of 1,000 yuan/ton in one month. Due to weak demand and increasing supply and demand, viscose staple fiber prices are under pressure and fall by 600 yuan/ton in one month. The trend of cotton is relatively stable, so the recent price difference between cotton and viscose staple fiber has expanded to more than 2,000 yuan / ton, and the price difference with polyester staple fiber has dropped to about 6,500 yuan / ton.

This year's viscose staple fiber loading rate fluctuated between 75-85, lower than the same period of last year, which is closely related to the rapid expansion of viscose production capacity in the past two years, and also caused the viscose staple fiber prices to continue to be weak. The polyester staple fiber load rate fluctuated between 60 and 80, except for February, which was basically flat or slightly higher than the same period last year.
