While polyester leaders struggle with thin margins in PX-PTA, Hengyi Petrochemical has moved the battle downstream with a 4.87 billion yuan investment. This capital, directed at a 400,000-ton annual PA6 melt direct spinning project, is not simple capacity expansion but a deliberate shift of profit focus along the nylon chain.
Event Background
According to the listed company announcement, Hengyi will implement the project through two subsidiaries: Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, located in the Guangxi New Materials Industrial Park and the Yizhijin New Materials Industrial Park respectively. The construction period is 18 months, funded by internal and external financing. Once operational, Hengyi's nylon business will extend from PA6 chip production to spinning, filling a critical processing gap.
Notably, Guangxi Hengyi currently operates a 600,000-ton annual PA6 chip plant, running at full capacity in 2026. This project is not starting from scratch but building on existing raw material capacity. For buyers, this signals that Hengyi's nylon supply will diversify from chips to include spun yarn, enhancing supply chain stability and flexibility.
Industry Impact
Melt direct spinning is the technical core of this investment. Compared with traditional batch chip spinning, Hengyi's self-developed process eliminates chip packaging, warehousing, and transfer steps, reducing water consumption by about 80% and electricity by 30%. These figures reflect a cost structure reshaping—saving intermediate steps not only lowers energy use but also shortens production cycles and reduces inventory pressure. For downstream weaving and apparel companies, shorter raw material supply cycles mean greater flexibility in responding to order fluctuations.
From an industry perspective, PA6 melt direct spinning is not new, but large-scale deployment by leading firms is changing the competitive landscape. As a leader in both polyester and nylon, Hengyi's downstream expansion replicates its integrated polyester strategy—keeping profits within the system from raw materials to spinning. This pressures small chip producers who struggle to match cost and scale.
For foreign trade companies, demand for nylon fabrics has been rising, particularly in sportswear and outdoor gear. After the project comes online, domestic PA6 spinning supply will increase, potentially reducing reliance on imported high-end nylon yarn. However, the 18-month timeline means no immediate supply shift; buyers need not rush to adjust strategies but should monitor capacity ramp-up in Guangxi and Hangzhou.
