While the spandex industry is still struggling with low-end overcapacity, an established chemical fiber company has chosen to double down on the fine-denier segment. On August 18, Xinxiang Chemical Fiber broke ground on the second phase of its 100,000-ton functional spandex project, with all capacity dedicated to 20D and below products. Behind this move lies a deep divergence in the spandex market: conventional grades yield thin margins, while ultra-fine denier is in short supply.
Background
The second phase is not an isolated event. It follows the first phase, which is expected to start production by the end of this year. The new phase adds a main production workshop with an annual capacity of 50,000 tons, covering 65,000 square meters. The entire project is planned for 100,000 tons, all focused on functional fine-denier spandex, signaling a clear bet on the high-end niche.
In terms of technology, the project uses continuous polymerization dry spinning, equipped with a unique 200-spindle spinning duct, automatic doffing, and intelligent sorting systems. These details are not for show; they directly address efficiency and quality—fine-denier spandex requires high uniformity, and multi-position design boosts output and consistency. Meanwhile, AI-based energy distribution aligns with the green transformation policy in textiles.
Industry Impact
The spandex industry is undergoing supply-side reshaping. Low-end capacity is phasing out due to thin profits, while demand for 20D and below products is expanding, driven by sportswear, high-end home textiles, and functional underwear. Xinxiang Chemical Fiber's move capitalizes on this upgrade trend.
For buyers, this means faster import substitution of high-end spandex. Previously, ultra-fine denier was mostly imported, with high prices and long lead times. After the second phase is operational, domestic supply will increase significantly, potentially breaking this bottleneck. For factories, the new capacity brings not just volume but also a technological demonstration—if the 200-spindle duct and intelligent sorting prove successful, they may trigger a new round of equipment upgrades across the industry.
Regionally, the project will fill a gap in the high-end textile material chain in Xinxiang and the Central Plains. Traditional chemical fiber bases like Keqiao and Shengze focus on conventional fabrics, while fine-denier spandex is a high-value segment. This project helps the region shift from scale expansion to quality and efficiency, enhancing its voice in the national textile landscape.
Practical Advice
For Purchasers - Monitor the first phase's commissioning (by year-end) and lock supply contracts for 20D and below fine-denier spandex early to avoid price hikes or shortages. - Compare the cost-performance of domestic vs. imported fine-denier spandex, especially testing domestic yarn on high-speed warp knitting and circular knitting machines. - Watch price fluctuations from low-end capacity phase-out; consider reducing inventory of conventional grades and shift capital to high-value products.
For Foreign Trade Companies - Treat fine-denier functional spandex as a new export growth point, especially targeting Southeast Asia and South Asia, where sportswear and underwear industries are upgrading rapidly. - Leverage Xinxiang Chemical Fiber's smart manufacturing label to strengthen supply chain stability and green image in overseas markets. - Track '15th Five-Year Plan' policies on new materials to align with domestic leaders and capture policy dividends.
The competition in fine-denier spandex is just beginning. Xinxiang's move may prompt more chemical fiber companies to follow, and the ultimate beneficiaries will be the entire textile supply chain.
