Polyester Filament Yarn Market Enters a Stalemate: Price Drop Signals in Changshu Warrant Caution for Downstream Buyers

The price list from the Changshu polyester filament yarn market on June 28, 2026, sends a clear signal: prices for certain regular specifications have started to decline, while overall trading volumes remain sluggish. For downstream weaving mills and traders, this means cost pressure is easing structurally, but it also suggests the market may enter a prolonged stalemate.

Structural Characteristics of the Price Adjustment

The price drop is not a broad collapse but is concentrated in specific specifications. According to price comparisons between June 25 and 28, the FDY 100D/48F specification (from Tongxiang Xinfengming and Tiansheng Chemical Fiber) dropped by 100 RMB/ton, from 8,800 to 8,700 RMB/ton, a decline of about 1.14%. In contrast, fine-denier specifications like FDY 68D/24F and 75D/36F remained stable at 9,200 and 9,000 RMB/ton, respectively.

A similar divergence is seen in DTY: the 75D/36F and 100D/36F specifications each dropped by 100 RMB/ton, to 10,200 and 10,000 RMB/ton, while coarser deniers like 150D/144F held steady at 9,400 RMB/ton. This pattern of "regular specs leading the decline, fine/coarse specs holding firm" reflects structural shifts in downstream demand.

Raw Material Transmission and Market Sentiment

The decline in polyester filament yarn prices is directly linked to the weakness of upstream polyester raw materials. Public market data shows that PTA and MEG prices have been trending down recently, further weakening cost support. Under inventory pressure, polyester plants have had to cut prices to stimulate sales, but downstream weaving mills' purchasing willingness remains low.

Changshu, as a key polyester yarn distribution and draw-texturing hub in China, often serves as a bellwether for the broader market. The current combination of falling volumes and falling prices essentially reflects the digestion of accumulated inventory from previous periods. For draw-texturing and weaving mills, lower raw material costs mean reduced production expenses, but also pressure on the valuation of finished goods inventory.

Transmission Effects Down the Chain

This price adjustment impacts different segments of the supply chain unevenly. For water-jet weaving mills that primarily use regular FDY 100D and DTY 100D, raw material costs have dropped by about 1%, which directly improves profit margins in a highly competitive order environment.

However, the price firmness of fine-denier and functional specifications indicates that differentiated products still command strong pricing power. Buyers should pay closer attention to specification substitution possibilities. For instance, some weaving mills may consider switching some orders from FDY 75D to FDY 100D to take advantage of current price advantages.

Market Outlook and Operational Recommendations

From the perspective of polyester raw material supply-demand fundamentals, polyester yarn prices are more likely to fall than rise in the near term. PTA capacity is still being released, while downstream demand is constrained by the pace of recovery in end-use apparel export orders, making it difficult to drive a meaningful rebound. Over the next two weeks, Changshu market polyester yarn prices are expected to have room for another 50-150 RMB/ton decline, especially for high-inventory regular specifications.

For Buyers - This is a window to lock in inventory for regular specifications (e.g., FDY 100D, DTY 100D). It is advisable to purchase in batches rather than all at once to mitigate price fluctuation risk. - For fine-denier or functional specifications, consider delaying purchases until prices follow the downtrend before restocking. - Closely monitor PTA and MEG futures markets; if raw material prices stabilize, the pace of polyester yarn price cuts may slow.

For Mills (Draw-texturing/Weaving) - Draw-texturing mills should prioritize consuming high-cost raw material inventory to avoid book losses from falling finished yarn prices. - Weaving mills can adjust their product mix to increase the proportion of orders for regular specifications, leveraging lower raw material costs to win more orders. - It is recommended to sign short-term fixed-price or point-price contracts with upstream polyester plants to lock in procurement costs.
