Weak Cost Support Keeps China Polyamide Filament Market Sluggish in Mid-June

China's polyamide filament market entered a sluggish consolidation phase during the third week of June 2026, following earlier price cuts. POY, DTY, and FDY prices stabilized at low levels as upstream raw materials, including caprolactam and PA6 chips, failed to offer any cost-side support. Concurrently, downstream textile enterprises maintained a cautious wait-and-see approach, limiting purchases to immediate needs. The dual-weakness scenario leaves manufacturers facing mounting core pressure.
