Diverging Polyester Filament Prices and Stable Yarn Markets: Signals from Shengze and Jiaxing

In late August, the light textile markets in Shengze and Jiaxing saw moderate-to-low trading volumes for polyester filament, with prices showing a chaotic pattern. Yet beneath the overall weakness, product-level divergence carries more signal than the headline numbers. Mainstream polyester producers only cut listed prices by 100 CNY/ton, but actual transaction discounts were more flexible—indicating a stronger willingness to destock, with price negotiations shifting from open cuts to hidden concessions.

Market Context

The immediate trigger was the pullback in PTA and MEG futures. The wobbling raw material costs quickly transmitted to spot polyester filament. However, polyester plants do not face heavy inventory pressure, so most kept list prices stable, only offering negotiation room on bulk deals. This 'stable on the surface, flexible underneath' approach reflects factories' desire to protect margins while accommodating cautious downstream buying.

Looking at product structure, demand divergence is clear. POY fine-denier items (50D/72F, 75D/72F, 75D/144F, etc.) saw only small purchases from texturizers, while intermingled POY sold poorly. In FDY, 48D/48F and 63D were buoyed by rising taffeta lining demand, with 48D/48F quoted around 10,200 CNY/ton and wider price gaps among mills. The 128D/36F, heavily used for oxford fabric, moved briskly, while 100D was mediocre. Bright fine-denier FDY slipped, but bright FDY 30D/24F, used in polyester-nylon fabrics, saw active buying. Matte FDY outperformed semi-dull and bright, with 40D/48F supported by high-density taffeta and casual wear. In DTY, bright multi-lobal flat yarns were favored, while regular DTY was quiet.

Industry Impact

This hot-and-cold mix across products offers direct clues for upstream scheduling and downstream procurement. For polyester mills, strong fine-denier FDY signals sustained lining orders, while the decline in bright fine yarns hints at cooling demand for polyester-nylon fabrics. For weavers, the active 128D confirms the resilience of oxford fabric (used in bags, tents), while sluggish 100D may correspond to weakness in certain apparel fabrics.

The yarn market tells a different story: cotton yarn prices were stable, with 32s selling well and J21s also moving, mainly for fugui-fang fabric; polyester-cotton blends were steady, with 80/20 45s seeing large volumes; some polyester-viscose blends edged up, with 65/35 40s moving well. Pure polyester yarn had little activity except 45s, with prices weak-to-stable; polyester staple fiber was unchanged, with 1.56*38 cotton-type center price around 8,050 CNY/ton. Viscose staple fiber held steady, with latest center price at 14,400 CNY/ton.

The coexistence of weak polyester filament and stable yarn reflects a time lag in cost transmission along the chain. Polyester filament is directly tied to PTA/MEG futures and reacts quickly; yarns, supported by cotton and viscose, plus relatively stable end orders, adjust later and less. However, steady polyester staple fiber alongside sluggish pure polyester yarn sales suggests downstream weaving is hesitant on polyester products; if filament prices continue to fall, pure polyester yarn may face catch-down pressure.

Practical Advice

For Buyers - Procure polyester filament in batches to avoid locking in large volumes at once, as short-term prices may still edge down; wait for better deals. - Focus on active items like fine-denier FDY (48D/48F, 63D) and 128D/36F, which have strong demand support and firmer prices; consider early stocking. - For differentiated items like bright FDY 30D/24F, place small trial orders based on your fabric orders to lock in cost-effectiveness.

For Foreign Trade Companies - Build a buffer in quotes for potential polyester filament price drops to protect order margins. - Watch export demand for matte FDY and high-density taffeta fabrics, which still have growth potential in casual and outdoor products. - Yarn products (e.g., cotton 32s, T/C 80/20 45s) are stable options for long-term contracts, but be mindful of potential volatility in pure polyester yarn.
