On the morning of July 14, polyester chain futures collectively strengthened, with staple fiber leading the chemical sector with a 3.77% gain to 7,372 yuan per ton. PTA rose 3.52% to 5,824 yuan per ton, while bottle-grade chip futures surged 4.31% to 7,162 points. In contrast, cotton and cotton yarn posted only marginal gains of 0.06% and 0.24%, at 16,135 yuan and 22,590 yuan per ton respectively. This divergence highlights fundamentally different driving forces across textile raw materials.
Cost Push and Supply Tightening
The strength in staple fiber and PTA is not isolated. Over the past month, international crude oil prices have climbed steadily, with WTI returning above $80 per barrel, driven by OPEC+ production cuts and geopolitical risk premiums. As PX is the direct upstream of PTA, higher crude directly raises PTA production costs. Meanwhile, multiple domestic PTA plants entered scheduled maintenance in early July, dragging operating rates to around 78% and tightening spot supplies. On the staple fiber side, several major mills also reduced loads during maintenance, amplifying bullish sentiment in futures markets. The sharp rise in bottle-grade chip reflects seasonal demand from the beverage packaging sector, where July and August are peak consumption months, accelerating inventory destocking.
Conversely, cotton and cotton yarn saw very limited gains. Zhengzhou cotton futures oscillated narrowly around the 16,000 yuan mark, lacking fresh fundamental drivers. While commercial cotton inventories have declined from earlier levels, they remain higher than last year. Downstream fabric mills show weak buying interest for cotton yarn, preferring hand-to-mouth purchases. The sluggishness in cotton yarn futures directly mirrors weak end-demand—weaving sector operating rates hover around 65%, with grey fabric inventory destocking slow and price transmission chains blocked.
Profit Distribution Under Pressure
The rapid polyester chain rally is reshaping profit structures across the value chain. Staple fiber and PTA margins have improved, but downstream products like polyester filament, taffeta, and springy fabric have yet to see corresponding price hikes. In Shaoxing and Shengze, some weaving mills report that raw material costs have risen from 35% to 38-40% of total production costs within a week. If the rally persists, processing margins will be significantly compressed. Dyeing and printing mills also face pressure, as disperse dye prices remain flat but energy costs for steam and electricity have increased with summer peak demand.
For export-oriented firms, the combination of yuan volatility and raw material inflation creates a sensitive window for adjusting export quotes. With Southeast Asian order backflows not yet firmly established, China's textile price competitiveness is eroding. If polyester raw material prices stay elevated, exporters may face a difficult choice between booking orders and protecting margins.
Outlook: Near-Term Bullish, Medium-Term Risks
Technically, staple fiber futures have broken above the 7,300 yuan resistance, with the next barrier near 7,500 yuan. PTA needs to confirm the 5,800 yuan level. The bullish logic remains valid in the near term: crude is prone to further gains, PX supply is tight, and polyester mill inventories are low. But risks are accumulating: downstream resistance to high-priced raw materials is building, with some mills planning to reduce operating rates to digest inventories. If export garment orders fail to pick up after August, the polyester chain rally may lack sustainability.
