Direct-spun polyester staple fiber (PSF) prices in China saw a roller coaster a fluctuation during July and August. The operating rate of PSF industry fell from 80 per cent to 72 per cent in the second half of August and is expected to recover to 80 per cent.

Accordingly, polyester feed stocks are supposed to buoy PSF better in September than in August. As a whole, direct-spun PSF price will rebound in September on better demand while restrained by its high operating rate. A very large part of the growth in polyester has come from China with India and Southeast Asia also contributing. In the case of China, both polyester production and apparent domestic demand for the fiber have been very strong. China accounts for 69 per cent of all polyester fiber production globally, and if India and Southeast Asia are added, these three regions represent 86 per cent of global production.

Polyester staple fiber is available in different deniers with different cut-lengths.PSF is mainly produced in India, China, Taiwan, Indonesia, Vietnam, Malaysia, and Korea. PSF is mainly used for fiber fillings in pillows and sofas. It is also used widely in spinning to make polyester spun yarn which is then knitted or weaved into fabrics.
