While the domestic spandex market still struggles with the pain of low-end capacity consolidation, leading players have already set their sights on the next frontier: products of 20 denier and below. On August 18, Xinxiang Chemical Fiber's Phase II of its 100,000-ton functional spandex project broke ground, with all output dedicated to 20D and finer microdenier spandex—a clear signal that the competitive logic in the spandex industry is shifting from 'tonnage' to 'fineness.'
Background
The Phase II project plans a main workshop with an annual capacity of 50,000 tons of spandex, covering a building area of approximately 65,000 square meters, along with auxiliary production and living facilities. The process adopts continuous polymerization dry spinning, with core equipment featuring a world-unique 200-end spinning duct, complemented by automatic doffing and intelligent sorting systems. Process control is fully digitalized. The power system incorporates high-efficiency machine rooms and AI-based energy distribution, aiming to create a benchmark for intelligent, green factories.
Notably, Phase I is expected to commence production by the end of this year, with Phase II following closely. Together, the two phases will form a total functional spandex capacity of 100,000 tons. At a time when the industry is generally cautious about expansion, Xinxiang's decision to increase investment in high-end microdenier is clearly not a simple capacity replication but a strategic response to downstream demand structure—sportswear, high-end home textiles, and functional intimate apparel are driving demand for finer denier and better skin-friendly properties, pushing 20D and below microdenier spandex up the demand curve.
Industry Impact
From the industry landscape, the domestic spandex market is in a phase of differentiation: 'low-end consolidation, high-end expansion.' Price competition in conventional specifications remains fierce, squeezing profit margins, while ultra-fine and functional products, due to higher technical barriers and limited supply, enjoy stronger pricing power. By dedicating Phase II entirely to microdenier, Xinxiang's capacity structure will shift toward high value-added segments, potentially avoiding red-ocean competition and directly meeting downstream high-end fabric procurement needs.
For buyers, the deeper implication lies in supply chain stability. The domestic substitution rate for 20D and below microdenier spandex still has room for improvement, with some high-end applications relying on imports. Once Phase II reaches full production, it will effectively supplement domestic high-end spandex supply, shortening lead times and reducing inventory costs. Meanwhile, efficiency gains from the 200-end spinning duct may translate into more competitive pricing, offering downstream fabric manufacturers better cost options.
Furthermore, the project's emphasis on '5G+Industrial Internet' and AI-based energy management signals a shift from labor-intensive to data-driven production. For factories, future competitiveness will depend not only on equipment scale but also on digital operational capabilities—those who can implement intelligent inspection and precise control will build moats in quality consistency and energy consumption.
