*** per cent Polyester yarn prices reflected the downstream impact of the raw material cost softening, with both assessed grades posting modest declines on a week-on-week basis. **-count (**s) Polyester Yarn Free-on-Board (FOB) China edged lower by *.** per cent, from $*.***/kg to $*.***/kg, while **-count (**s) Polyester Yarn FOB China declined by *.** per cent, from $*.***/kg to $*.***/kg. The near-parallel movement across both counts indicates a systemic rather than grade-specific pressure, consistent with a broad raw material-driven cost correction rather than a demand-side disruption. The decline in **s yarn (finer count, higher value-added) marginally mirrors that of **s, suggesting that even premium-grade products are not immune to feedstock-driven pricing pressure.
Ethylene oxide, the first-stage derivative of ethylene and a critical upstream precursor to MEG, exhibited a broadly stable to marginally mixed price trend during the reference week.
