On August 31, the textile bulk commodity market showed a rare divergence: PTA rose 1.45% in a single day, polyester staple fiber followed with a 0.93% gain, and cotton rose 0.85%, while raw silk fell 0.21%. Behind these numbers lies a collision between upstream cost logic and weak downstream demand—how smoothly cost pass-through occurs will determine profit distribution across the textile chain in the coming quarter.
Market Background
Year-on-year data reveals a more concerning cost pressure than daily fluctuations. PTA is up 28.87% year-on-year, acrylonitrile surged 44.12%, and the three major polyester filament varieties (POY, DTY, FDY) all rose over 21%, while nylon products recorded increases between 14% and 21%. This indicates that the cost center for chemical fiber raw materials has systematically shifted upward over the past year, not merely a short-term fluctuation.
In contrast, cotton yarn (21S, 32S) rose only 5.6% to 5.9% year-on-year, viscose staple fiber increased 10.43%, and spun rayon yarn rose 5.66%. The moderate performance of the cotton spinning chain reflects limited capacity of downstream weaving and garment orders to absorb high-priced raw materials, with price transmission clearly blocked at the cotton spinning stage.
Raw silk was the only declining variety, falling 0.21% from the previous day and down 9.35% year-on-year. As a core raw material for the silk industry, its persistent weakness is directly linked to sluggish terminal silk consumption and insufficient export orders, as well as increased cocoon supply in some regions, creating a loose supply-demand balance.
Industry Impact
The strength of chemical fiber raw materials and the weakness of cotton spinning and silk outline a typical pattern of "strong upstream, weak downstream, squeezed middle." Rising PTA and polyester staple fiber directly push up production costs for polyester yarn and fabrics, but downstream weaving mills and garment companies cannot raise order prices simultaneously—squeezing profit margins at the weaving stage.
For procurement managers, the current moment requires reassessing inventory strategies. Chemical fiber raw material prices are at historical highs; chasing further increases risks cost inversion, but waiting for a pullback could mean missing the chance to lock in prices. Especially for polyester filament and nylon, with year-on-year gains exceeding 20%, the market has formed a consensus on high costs, making a sharp near-term correction unlikely.
Foreign trade enterprises face even greater challenges. Overseas clients have limited acceptance of price hikes, but raw material costs are rigidly rising, and the window for adjusting export quotations is narrowing. Acrylonitrile's 44.12% year-on-year increase directly affects acrylic and some functional fabric price expectations, requiring more cautious profit calculations for related export orders.
Meanwhile, the decline in raw silk provides a relative cost advantage for silk-based products. For foreign trade companies focusing on silk fabrics, this could be a window to adjust product mix and win orders. However, persistently low raw silk prices may also reflect weak terminal demand, and low-cost raw materials may not necessarily translate into actual orders.
