Polyester DTY (Draw Textured Yarn) is a type of textured polyester yarn produced from Polyester Pre-Oriented Yarn (POY) through a process of drawing and texturing. The production involves high-speed spinning of polyester POY, followed by draw texturing and false twisting, resulting in a yarn with high elasticity, soft texture, and excellent durability. DTY is widely used in textiles for its versatility, making it suitable for applications such as apparel, home textiles, and industrial fabrics.

The key characteristics of Polyester DTY include:

• High elasticity and bulkiness, making it ideal for fabrics requiring stretch and recovery.
• Soft hand feel, suitable for comfortable and lightweight textiles.
• Diverse fineness options, ranging from 20D to 600D, allowing for customization based on application needs.

Common applications of Polyester DTY include:

• Women's wear, sportswear, and outerwear due to its elasticity and comfort.
• Socks, underwear, and home textiles because of its softness and durability.
• Automotive and industrial fabrics where strength and resilience are critical.

The polyester filament market, including Polyester DTY, has shown a volatile and weak trend in September 2025, contrary to the traditional peak season expectations. Key factors influencing this trend include:

• Insufficient cost support: Despite stability in crude oil prices, the restart of some PTA plants has increased supply pressure, leading to weaker raw material costs. As of September 12, 2025, the price of polyester DTY (150D/48F low-elastic) ranged between RMB 8,000-8,150/ton.
• Subdued demand: Downstream weaving mills have maintained cautious procurement strategies, with loom operating rates in Jiangsu and Zhejiang regions at approximately 64%, 4.4 percentage points lower than the same period last year. High inventory levels of grey fabrics have further dampened new orders.
• Inventory pressure: Polyester filament inventories have accumulated, with DTY inventories reaching 31.1 days, an increase of 1.4 days week-on-week. Manufacturers are keen to ship products, leading to negotiated discounts in transactions.

The short-term market is expected to remain volatile with a weaker bias. However, opportunities lie in:

• Cost-side adjustments: If raw material prices strengthen, it could provide support to DTY prices.
• Demand recovery: Any improvement in downstream demand during the upcoming holiday season could boost market sentiment.
