The penetration rate of fine-denier spandex below 20D is reshaping the competitive dynamics of the spandex industry. On August 18, Xinxiang Chemical Fiber started the second phase of its 100,000-ton functional spandex project—a move that goes beyond simple capacity addition, targeting a precise position in the high-end segment. While conventional specifications are trapped in price wars, ultra-fine denier products are becoming a key differentiator for leading companies, thanks to higher technical barriers and added value.
Background
The second phase plans a main production workshop with an annual capacity of 50,000 tons of spandex, covering a building area of 65,000 square meters, entirely dedicated to functional fine-denier spandex of 20D and below. Notably, it adopts a continuous polymerization dry spinning process and features the world's unique 200-head spinning duct, coupled with automatic doffing and intelligent sorting systems, as well as AI-based precise energy distribution. The overall digitalization and intelligence level of the plant sets a benchmark in the industry.
In terms of timeline, the first phase is expected to start production by the end of this year, and the second phase follows closely. This indicates the company's firm judgment on the market window. The 'build-while-invest' rhythm suggests that Xinxiang Chemical Fiber aims to secure capacity before high-end spandex demand fully ramps up, avoiding order losses due to delivery delays.
Industry Impact
The spandex industry is undergoing structural adjustments with low-end capacity phase-out and expanding high-end demand. Conventional products face severe homogeneity and price competition, while downstream upgrades in sportswear, high-end home textiles, and functional intimate apparel are driving the penetration of ultra-fine denier spandex, which offers superior skin comfort, delicate elasticity, and adaptability. This trend means that Xinxiang's new capacity will directly serve a high-prosperity track rather than intensify competition in the existing market.
From a regional perspective, the project in Xinxiang, Henan, will fill the gap in the local high-end textile new material industry chain. In the past, the central region's chemical fiber industry focused on conventional varieties, relying on the eastern coast or imports for high-value-added segments. This move is expected to drive the formation of a fine-denier spandex upstream and downstream cluster, offering shorter delivery times and more flexible customization for buyers.
For the industry as a whole, the application of unique technologies like the 200-head spinning duct marks a shift from 'scale expansion' to 'quality and efficiency.' Once such a technology gap is established, entry barriers rise, accelerating the exit of outdated capacity and strengthening the market influence of leading companies. For foreign trade enterprises, domestic substitution of high-end fine-denier spandex reduces dependence on imported raw materials, enhancing cost controllability of end products.
