While the spandex industry frets over overcapacity in low-end products, a contrasting set of data is rewriting the competitive rules: market penetration of 20D and below fine denier spandex keeps rising, while conventional grades face price wars. On August 18, Xinxiang Chemical Fiber's phase II of its 100,000-ton functional spandex project broke ground, with 50,000 tons of capacity all aimed at this niche. This is not just capacity expansion; it signals that domestic spandex competition has shifted from scale to technological intensity.
Event Background
The phase II project is located in Xinxiang, mainly constructing a 50,000-ton spandex main production workshop and auxiliary facilities, with a building area of 65,000 square meters. All capacity will focus on 20D and below functional fine denier spandex, which is becoming the preferred raw material for sportswear, high-end home textiles, and functional intimate apparel due to its skin-friendliness and delicate elasticity. Deputy General Manager Zhu Shengtao revealed that phase I is expected to start production by year-end, while phase II targets the '15th Five-Year Plan' forward layout, aiming to establish a voice in the high-end niche.
Notably, phase II adopts continuous polymerization dry spinning technology, equipped with the world's unique 200-head spinning duct, and introduces automatic doffing and intelligent sorting systems. This means single-line efficiency and product consistency will improve significantly, while common pain points such as high energy consumption and heavy manual labor are being resolved digitally. For buyers, the direct benefit of equipment upgrades is improved supply stability and quality uniformity, not just price advantages.
Industry Impact
The spandex industry is undergoing a supply-demand reshaping, with low-end capacity being phased out, and ultra-fine, functional, and green products becoming the growth pole. The driver is downstream consumption upgrades: sportswear demands higher resilience and fatigue resistance, high-end home textiles require softer touch, and functional intimate fabrics impose strict standards on fineness and uniformity. 20D and below fine denier spandex fits these needs, so penetration continues to rise.
The landing point of Xinxiang's phase II is a turning signal from 'having' to 'excellent'. In recent years, domestic spandex capacity expansion has mostly focused on conventional specifications, leading to intensified homogenization. By dedicating all 50,000 tons to fine denier products, the project avoids the red ocean and positions in the high-value segment. Combined with the '5G + Industrial Internet' concept, the project aims to build a smart factory benchmark, which will have a ripple effect on the regional supply chain—upstream raw material suppliers must match more precise polymerization control, while downstream weaving enterprises can obtain stable differentiated raw material supply.
For the traditional fiber industry, the significance goes beyond a single expansion. It demonstrates a feasible path from scale expansion to quality and efficiency: through technological equipment upgrades and digital management, fine denier spandex, once a 'luxury', becomes a mass-producible conventional category. This may force peers to reassess product structures, accelerate low-end capacity exit, and push the entire industry toward new quality productivity.
