While the spandex industry is still debating overcapacity in low-end segments, a contrasting set of data reveals the direction: the market penetration of fine-denier spandex (20D and below) is steadily rising, while profit margins for conventional specifications are shrinking. On August 18, the phase II of Xinxiang Chemical Fiber's 100,000-ton functional spandex project broke ground, with all capacity dedicated to this high-value-added category. This is not just an expansion at the enterprise level but a microcosm of the entire chemical fiber industry chain migrating toward high-end products.
Background
The phase II project is clearly defined: a main production workshop with an annual capacity of 50,000 tons of spandex, covering a floor area of 65,000 square meters, plus auxiliary production and living facilities. The project adopts a continuous polymerization dry spinning process, with core technology featuring the world's only 200-spindle spinning duct, complemented by automatic doffing and intelligent sorting systems, as well as AI-based energy efficiency allocation. These technical details indicate that this is not a simple replication of scale but a benchmark of modern factories built on digitalization and intelligence.
Notably, phase I is progressing smoothly and is expected to commence production by the end of this year, while phase II targets functional fine-denier spandex of 20D and below. The combined capacity of 100,000 tons will significantly enhance Xinxiang Chemical Fiber's share in the high-end spandex segment. Vice General Manager Zhu Shengtao positioned it as a strategic project for the "15th Five-Year Plan," reflecting the company's foresight into the competitive landscape of the next five years.
Industrial Impact
The domestic spandex industry is undergoing profound structural adjustment. Low-end capacity is being phased out, while demand for ultra-fine, functional, and green high-end products continues to expand, becoming a core necessity for textile industry upgrading. The iterative evolution of downstream sectors such as sportswear, high-end home textiles, and functional intimate apparel is driving demand for spandex of 20D and below—products known for their skin-friendliness, delicate elasticity, and strong adaptability, with increasing market penetration. Xinxiang Chemical Fiber's phase II project precisely captures this trend, signaling a shift from scale expansion to quality and innovation-driven growth.
For the regional industrial cluster, the project will fill the gap in the high-end textile new material supply chain. Xinxiang, located in the central plains, is surrounded by upstream and downstream enterprises in cotton spinning, dyeing, and garment manufacturing, but has long relied on external sources for high-end spandex raw materials. Once phase II is operational, it will effectively shorten the procurement radius within the region, reduce logistics and time costs, and enhance the responsiveness of the entire industrial cluster. For downstream buyers, this means a more stable source of high-end materials and more competitive price expectations.
