some spinners in Hebei changed production from polyester yarn made of virgin PSF to the one made of close virgin PSF

In addition, some spinners in Hebei changed production from polyester yarn made of virgin PSF to the one made of close virgin PSF. Firstly, the market was bearish at present and the spinners faced high inventory yet low profit. Secondly, the price spread between virgin PSF and close virgin PSF widened to 1,700-1,800yuan/mt, and the spinners had to seek for more economical raw materials. Besides, the shortage of raw materials which could not be delivered from Jiangyin also played an important role.
