While the chemical fiber industry remains mired in debates over overcapacity, Hengyi Petrochemical has answered with a 4.87 billion yuan investment: the future belongs to melt direct spinning, not traditional chip spinning. This decision signals a quiet shift of profit centers in the nylon chain from raw materials to downstream processing, and a clear attempt by leading players to reshape competitive dynamics through technological barriers.
Event Background
According to public investment announcements, Hengyi plans to build a 400,000-ton annual PA6 melt direct spinning project through its subsidiaries Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, with an 18-month construction period. Funding will come from internal resources and external borrowing. The project will be located in Guangxi New Materials Industrial Park and Yizhijin New Materials Industrial Park, employing the company's self-developed PA6 melt direct spinning core technology.
This technology contrasts sharply with traditional batch chip spinning. Public data shows it cuts water consumption by about 80% and electricity use by 30%, while eliminating intermediate steps like chip packaging, warehousing, and transport. What does this mean for cost-sensitive downstream buyers? Lower water and electricity consumption translates directly into competitive fabric prices. For factories facing growing environmental compliance pressure, reduced pollutant and waste emissions offer a strong defense during inspections.
Notably, Guangxi Hengyi New Materials currently operates a 600,000-ton PA6 chip production line running at full capacity throughout 2026. This provides a solid raw material foundation for the new project—the company won't depend on external chip suppliers, allowing it to control quality and costs from the source, an advantage most small chip-spinning firms cannot replicate.
Industry Impact
From a supply chain perspective, Hengyi's move extends its business from PA6 chip raw materials to downstream spinning, completing a key link in the nylon chain. The strategic significance lies in profit smoothing: when chip prices fluctuate, companies with spinning capacity can internally absorb changes, while those relying solely on chip trade or chip spinning face greater market risk.
The deeper impact lies in the demonstration effect on technology routes. If Hengyi's self-developed melt direct spinning proves mature, it could trigger a new wave of equipment upgrades across the industry. For leading chemical fiber firms, this is not just a cost-saving tool but a chance to build technological moats—whoever masters low-carbon, efficient processes first will gain pricing power in high-end nylon fabrics and engineering plastics.
However, the flip side is that technological iteration often accompanies the elimination of outdated capacity. Traditional chip-spinning enterprises, especially small and medium factories lacking R&D capabilities and financial strength, will face dual pressures of order loss and equipment depreciation. Industry concentration may further increase, and buyers will need to reassess suppliers' technology routes and long-term supply stability.
