The capacity structure of China's spandex industry is undergoing a visible shift. On August 18, Xinxiang Chemical Fiber broke ground on Phase II of its 100,000-ton functional spandex project in Xinxiang, Henan. This single 50,000-ton production line, entirely focused on 20D and below fine-denier products, is seen as a landmark addition to the high-end spandex supply side. As low-end capacity continues to exit, this move signals that leading enterprises are shifting their competitive focus from scale to technological density.
Event Background
The core highlights of Phase II lie in the generational gap in processes and equipment. According to publicly available industry information, the new workshop covers 65,000 square meters, adopts continuous polymerization dry spinning, and is equipped with a globally unique 200-spinneret spinning duct, complemented by automatic doffing and intelligent sorting systems, with fully digital process control. More notably, AI-based precise energy allocation is introduced in the power system—this is not just capacity expansion but a redefinition of production methods.
The two-phase construction pace also reveals the company's market judgment. Phase I is expected to be operational by the end of this year, with Phase II starting immediately after, timing that aligns with the rising demand curve for high-end fine-denier spandex. Downstream feedback indicates that the procurement share of 20D and below spandex in sportswear, high-end home textiles, and functional intimate apparel is increasing year by year, with skin-friendliness and fine elasticity becoming hard indicators for brands when selecting suppliers.
Industry Impact
The spandex industry has undergone a clear round of capacity reduction over the past two years, with prices for conventional specifications under pressure and some small and medium enterprises forced out. In contrast, gross margins for ultra-fine and functional products remain firm, with supply-demand gaps in certain specifications even showing temporary tightness. By committing all Phase II capacity to 20D and below products, Xinxiang Chemical Fiber is sending a clear signal: high-end fine denier is no longer a concept but a tangible profit growth point.
For buyers, this project will directly improve supply stability for high-end spandex. Reliance on imports or a few suppliers will ease, especially in functional spandex (e.g., antibacterial, cooling, moisture-wicking), where domestic self-sufficiency is expected to rise. For peers, the efficiency gains from the 200-spinneret spinning duct will create a new cost benchmark, putting greater exit pressure on capacities that fail to keep up with technological iteration.
From an industrial chain perspective, Xinxiang's layout also carries regional supply-chain significance. High-end spandex has been a weak link in the textile new-material chain in Henan and surrounding areas. After Phase II comes online, local supporting capabilities will strengthen, enabling faster response to downstream weaving enterprises. This geographic proximity advantage is becoming an invisible competitive edge in an industry where order lead times are shrinking.
