On August 18, Xinxiang Chemical Fiber started the second phase of its 100,000-ton functional spandex project. This investment decision stands out in a market where spandex producers generally face pressure—the project is entirely focused on 20D and below fine-denier products, aiming to secure a position in the high-value-added segment. For buyers, this is not just a capacity signal but a forecast of accelerating structural divergence in spandex supply.
Market Context
The domestic spandex market is at a critical stage where low-end capacity is being phased out while high-end demand expands. Industry data shows that price competition for conventional spandex is fierce, but ultra-fine and functional products command stronger pricing power due to technical barriers and concentrated supply. The second phase of the Xinxiang project plans 50,000 tons of annual capacity, with a main workshop covering 65,000 square meters. It adopts continuous polymerization dry spinning and features a globally unique 200-spinneret spinning duct, implying significantly higher capital intensity per unit capacity but also better uniformity and production efficiency.
The project deeply integrates 5G+Industrial Internet concepts, covering digital control from automatic doffing to intelligent sorting and AI-based energy management. For the industry, this is not just a single plant upgrade but a potential benchmark for "new quality productivity" in spandex—when traditional chemical fiber enterprises shift from scale expansion to quality and efficiency, equipment and process generation gaps will directly determine their competitive position at the high end.
Phase I is expected to be operational by the end of the year, with Phase II following closely. The combined 100,000 tons of capacity release will significantly affect the supply-demand balance of fine-denier spandex in the next two years. As downstream sportswear, high-end home textiles, and functional intimate apparel increasingly demand finer elastic properties and skin-friendliness, the penetration of 20D and below products is still rising. Xinxiang's heavy bet on fine denier is a clear wager on this structural trend.
Industry Impact
The expansion of fine-denier spandex will directly reshape buyer bargaining power. Previously, fine-denier products were in short supply, forcing buyers to accept high premiums and longer lead times. With projects like Xinxiang's second phase coming online, supply will increase noticeably, easing the bottleneck for high-end spandex. However, buyers must reassess suppliers' technical stability and batch consistency—fine-denier spinning is far more challenging than conventional grades, and capacity does not guarantee high yield rates.
For upstream raw materials, PTMEG and MDI demand will be supported by spandex growth, but more importantly, the 200-spinneret duct requires higher purity and uniformity of raw materials, potentially driving suppliers to upgrade product grades and fostering chain-wide quality improvements. Meanwhile, the proliferation of smart equipment will reduce labor costs but raise entry barriers, accelerating the exit of small players and increasing industry concentration.
From a regional perspective, Xinxiang is not a traditional textile hub, but this project fills the local gap in high-end textile new materials. For nearby garment and home textile enterprises, local supply means shorter logistics and faster response, which may attract more downstream capacity to the central-western region amid industrial transfer.
