While the spandex industry remains fixated on price wars in conventional deniers, the supply-demand gap in sub-20D fine denier products is widening quietly. On August 18, Xinxiang Chemical Fiber broke ground on Phase II of its 100,000-ton functional spandex project, with 50,000 tons of capacity dedicated entirely to this niche. The message is clear: high-end fine denier is no longer a concept but a decisive factor for industry ranking in the next cycle.
Event Background
The Phase II project centers on a 50,000-ton main production workshop covering 65,000 square meters, along with auxiliary and living facilities. Once fully operational, it will produce functional spandex of 20D and below, using continuous polymerization dry spinning technology, equipped with the world's only 200-spinneret spinning duct, and incorporating automatic doffing and intelligent sorting systems. Power management will leverage high-efficiency computer rooms and AI for precise allocation, positioning the plant as a benchmark for smart, digital, and energy-efficient manufacturing.
Phase I is also progressing and is expected to commence production by the end of this year. The combined 100,000-ton plan signifies a leap in Xinxiang Chemical Fiber's high-end spandex capacity. Strategically, the project is positioned for the 15th Five-Year Plan, with its production schedule closely aligned with the industry's current upcycle.
Industry Impact
The spandex market is undergoing structural reshaping. Low-end capacity is gradually exiting, while downstream sectors such as sportswear, high-end home textiles, and functional intimate apparel are upgrading, driving demand for superfine, functional, and green products. Sub-20D fine denier spandex, with its skin-friendly feel, delicate elasticity, and adaptability, is gaining penetration and becoming a core need for textile upgrading.
For buyers, the release of high-end fine denier capacity will ease supply tightness in certain specs, but it also raises the bar for suppliers' technical thresholds and quality control. Price competition in conventional deniers is unsustainable; companies with differentiated capacity will gain pricing power. For exporters, functional spandex offers higher added value, and new domestic capacity helps stabilize supply of premium raw materials, reducing import dependence and enhancing the international competitiveness of end products.
Regionally, the project fills gaps in the high-end textile new material supply chain in Xinxiang and surrounding areas, pushing traditional chemical fiber from scale expansion to quality, efficiency, and innovation. The application of digital and green technologies also provides a replicable smart manufacturing model, accelerating the industry's transformation toward new productive forces.
