The polyester filament market continued its upward trend this week (March 17-21), with all three major product lines posting price increases amid active trading.
Price Movements
POY 150D/48F rose 70 yuan/ton to 7,490 yuan/ton. DTY 150D/48F (low elastic) gained 80 yuan/ton to 8,660 yuan/ton. FDY 150D/96F increased 50 yuan/ton to 7,830 yuan/ton. Key drivers included PTA breaking 6,000 yuan/ton, seasonal demand pickup, and temporary supply tightness from polyester plant maintenance.
Downstream Demand
Weaving operations in Jiangsu-Zhejiang are running at 85%+ utilization, with some large-scale operations exceeding 90%. Raw material inventories at weaving mills average 12-15 days, below normal levels, with some mills beginning to increase procurement in anticipation of further price rises.
Outlook
The market is expected to remain firm next week, supported by seasonal demand strength and elevated costs. However, returning polyester capacity from maintenance may cap upside potential. Downstream buyers are advised to procure moderately based on order visibility.
