On June 22, the average sales rate of polyester filament among sample enterprises stood at only 39.5%, a marginal increase of 1.3 percentage points from the previous trading day. This figure indicates that for every 100 tons of polyester filament produced that day, fewer than 40 tons were absorbed by the market. Cautious downstream users have left spot transactions in a state of notable sluggishness.
Signals Behind the Data
A sales rate of 39.5% falls within a historically low range for the chemical fiber industry. More importantly, the slight uptick of 1.3% from the prior day is almost negligible. Industry data reveals a highly uneven distribution among sample enterprises, ranging from 120% to 0%. While a few companies achieved full or even over-capacity sales through promotions or urgent orders, the majority recorded rates between 30% and 45%, with some reporting zero sales for the day. This polarization indicates that demand is not entirely absent but is highly concentrated and unstable.
For buyers, this data signals that upstream inventories are accumulating, while downstream weaving and dyeing sectors have not seen the expected recovery in orders. As a core intermediate in the chemical fiber chain, the sales rate of polyester filament directly reflects the transmission efficiency from PTA (purified terephthalic acid) to polyester chips and ultimately to textile end-products. The current low level points to insufficient consumption in end-markets such as apparel and home textiles.
Chain Reactions Upstream and Downstream
The low sales rate of polyester filament will first exert pressure on upstream polyester chips and PTA segments. Polyester plants may face the need to reduce operating rates to control inventory growth. In fact, since mid-June, some polyester chip manufacturers have begun implementing production cuts or maintenance plans in an attempt to stabilize prices through supply contraction. However, the weakness in demand cannot be resolved by short-term supply adjustments alone.
From a regional industrial cluster perspective, key chemical fiber and weaving hubs such as Xiaoshan and Shaoxing in Zhejiang, as well as Shengze in Jiangsu, are major consumers of polyester filament. Weaving enterprises in these areas are generally experiencing a lull in orders—domestic markets have entered a traditional off-season, while foreign trade orders are limited due to high overseas inflation and ongoing destocking cycles. Weaving mill operating rates remain at 60-70%, with raw material procurement limited to small, just-in-time orders. Inventory hoarding is minimal. This "buy-as-you-use" strategy directly depresses the sales rate of polyester filament.
Price and Cost Squeeze
Behind the low sales rate lies a tug-of-war between price and cost. The main raw material for polyester filament, PTA, is heavily influenced by international crude oil fluctuations. Recently, crude oil prices have hovered in the $70-75 per barrel range, providing some cost support for PTA. However, polyester filament prices have struggled to follow suit, as end-demand cannot absorb higher raw material costs. This creates a profit-squeeze scenario where costs rise but product prices cannot.
For chemical fiber enterprises, this means reduced profit margins per ton. Some small-to-medium-sized polyester filament producers, facing the dual pressure of low sales rates and thin profits, may be forced to cut production or even shut down. Industry concentration is likely to increase, with leading companies better positioned to weather the off-season due to their scale and channel advantages.
