Polyester Chain Pullback and Filament Divergence: A Weekly Snapshot of the Shengze-Jiaxing Raw Material Market

Every pullback in polyester raw materials sends ripples through the light-textile markets of Shengze and Jiaxing. On August 29-30, weakening PTA and MEG futures directly pressured the transaction center of polyester filament, yet the market did not witness panic selling. Instead, a pattern of 'stable on the surface, flexible underneath' emerged. Major polyester plants kept official quotes mostly unchanged but offered discounts of around 100 yuan per ton on bulk transactions, with trading volumes moderate to low. This price resilience is supported by manageable inventory levels at polyester plants, but feedstock volatility has made downstream buyers cautious, increasing the probability of a short-term downward adjustment.

Variety Divergence: Demand Structure Shapes Price Trends The divergence within polyester filament tells a clearer story than the overall price movement. In the POY segment, fine-denier and multi-filament specs such as 50D/72F, 75D/72F, 75D/144F, 100D/192F, and 150D/288F were purchased in small lots by texturizing mills for differentiated fabrics. POY 150D/144F was quoted around 9,000 yuan/ton with negotiable discounts. In contrast, intermingled POY saw sluggish sales, indicating weak restocking appetite for conventional specs. In FDY, 48D/48F and 63D gained traction due to rising taffeta lining demand; 48D/48F was quoted around 10,200 yuan/ton, though price gaps among mills widened due to varying inventory levels. Oxford fabric consumption drove strong movement in 128D/36F, while 100D remained dull. Notably, bright FDY fine denier sales softened, but bright 30D/24F stayed active for polyester-nylon blends; matte FDY outperformed semi-dull and bright variants, with 40D/48F seeing decent demand for high-density taffeta and casual wear fabrics.

Yarn Market: Relative Stability with Local Bright Spots Compared with filament, the yarn market was calmer, yet local highlights persisted. Cotton yarn prices remained stable, with 32s maintaining strong sales for luxury-fu fabric, and J21s also moving. Polyester-cotton yarn prices were steady, with 80/20 45s seeing large volumes, reflecting rigid demand in workwear and home textiles. Polyester-viscose blends saw selective price increases, with 65/35 40s selling briskly, supported by stable viscose staple fiber prices, which were centered around 14,400 yuan/ton. Pure polyester yarn weakened, with only 45s showing some sales; overall prices were stable to soft, and polyester staple fiber prices were little changed, with 1.56*38 cotton-type centered around 8,050 yuan/ton. Viscose rayon yarn 30s moved reasonably, with prices temporarily stable. Overall, the yarn market is in an adjustment phase, with expectations of narrow-range consolidation ahead.

Industry Impact: Cost Transmission and Procurement Rhythm This soft correction in raw materials is reshaping downstream procurement rhythms. The slight easing in polyester filament prices offers a cost-saving window for weaving mills, but the choppy PTA/MEG trends create uncertainty, fueling a wait-and-see attitude. From an industry transmission perspective, the popularity of fine-denier FDY reflects the resilience of lining orders, while oxford fabric's pull on 128D/36F indicates steady demand from luggage and tent sectors. The strength of matte FDY aligns with the outdoor casual fabric trend. These structural bright spots provide relatively clear restocking directions for buyers. For polyester plants, manageable inventories mean no aggressive price cuts in the short term, but the strategy of 'prioritizing shipments' is set, making actual transaction prices more flexible.

Practical Recommendations ### For Buyers - Focus on FDY 48D/48F and 63D fine-denier specs; taffeta order support keeps prices firm, so consider moderate stockpiling. - Leverage flexible POY transaction terms to negotiate bulk discounts and lock in costs for common specs like 150D/144F. - For oxford-related specs (e.g., 128D/36F), stagger purchases based on order schedules to avoid inventory buildup.

For Foreign Trade Enterprises - For differentiated varieties like matte FDY 40D/48F, strengthen cooperation with fabric mills to develop high-density casual fabric exports. - Monitor the rising trend of polyester-viscose 65/35 40s and factor potential cost increases into quotations. - During the filament price correction, consider locking in forward orders to stabilize export costs.
