While the chemical fiber industry debates overcapacity, Hengyi Petrochemical has answered with a 4.87 billion yuan investment: rather than expanding in the crowded polyester market, it is targeting profits downstream in the nylon chain—melt direct spinning. The project, announced on August 13, involves two subsidiaries: Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, with a combined annual capacity of 400,000 tonnes of PA6 and an 18-month construction period. The dual-site strategy spans southwest and east China, signaling a shift from single-point expansion to a networked layout covering raw materials, spinning, and markets.
The core of this move is a self-developed melt direct spinning process, which replaces the industry-standard batch chip spinning. The benefits are quantitative: water consumption drops by 80%, electricity by 30%, and intermediate steps like packaging, warehousing, and transport are eliminated. For a company with scale, these numbers translate into substantial cost savings, lower carbon emissions, and reduced waste. This is not a minor tweak but a fundamental cost-curve shift.
Hengyi's existing 600,000-tonne PA6 chip plant in Guangxi, running at full capacity in 2026, provides a stable raw material base. The new project extends the value chain from chips to spinning, completing the integrated nylon layout. This integration smooths profit fluctuations when chip prices swing and enables faster response to spinning demand. For buyers, the implications are significant: lower procurement costs and improved supply chain stability. In an era of geopolitical and logistical uncertainty, a domestic source of high-quality PA6 reduces dependence on imports and reshapes bargaining power, especially in high-end nylon fabrics.
Regionally, the Guangxi-Hangzhou dual base is strategic. Guangxi offers proximity to raw materials and ASEAN markets, supporting export growth under RCEP; Hangzhou sits near the Yangtze River Delta textile cluster, serving premium customers. This will intensify competition with traditional nylon hubs like Shengze and Keqiao, but also drive upgrades in supporting industries. Smaller chip-spinning enterprises may face pressure—they cannot match Hengyi's cost efficiency and must differentiate through functional nylon products.
For procurement professionals, the key is timing: monitor the project's commissioning (expected around 2028) and sign long-term agreements to lock in cost advantages. Test the quality of melt-spun products against chip-spun ones, especially in dyeing uniformity and strength, through small trial orders. Optimize logistics by leveraging the dual bases—southwest orders from Guangxi, east China orders from Hangzhou.
For foreign trade companies, the low-carbon process offers a green supply chain narrative, aligning with EU carbon footprint requirements. The Guangxi base's proximity to ASEAN suggests cross-border supply chain opportunities under RCEP. However, be wary of price volatility from capacity concentration; consider floating pricing contracts and use futures to hedge PA6 raw material costs. In summary, Hengyi's investment is a bet on technology-led cost leadership, and its ripple effects will be felt across procurement, competition, and trade for years.
