Recently there is a poor demand for polyester industrial yarn in China. But polyester industrial yarn export growth expanded rapidly, far higher than that of 2015. Foreign buyers largely procured ahead of time. August/September exports may see negative growth rates. The G20 regulation did not affect PIY production much, only about 10 per cent of total PIY capacity in China. Downstream plants widely stocked raw materials with expectations of higher prices in future. Foreign sales were brisk in the first half of 2016. The polyester textile filament market was heavily impacted as a lot of plants shut down and spot prices were pushed up. Downstream may need to replenish their stocks and polyester industrial yarn plants may cut inventory at the point. Their profits were very thin. Demand for downstream products, for geo-technique or car use, etc. too decreased.
