While most chemical fiber companies still compete on the scale of chip production, Hengyi Petrochemical has placed its bet on the downstream spinning segment. A 4.87 billion yuan investment in a 400,000-ton annual PA6 melt direct spinning project is not just an addition to capacity; it signals that the value center of the nylon chain is shifting from raw materials to applications. For buyers, the price formation mechanism and supply stability of nylon fabrics may change due to such integrated layouts.
Background
Hengyi Petrochemical, through its subsidiaries Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, is simultaneously advancing a 400,000-ton annual PA6 melt direct spinning project in Guangxi and Hangzhou, with a total investment of 4.87 billion yuan and an 18-month construction period. The project will be funded by a mix of internal and external financing, reflecting the company's commitment. Notably, Guangxi Hengyi New Materials currently operates a 600,000-ton PA6 chip production line, which will remain at full capacity in 2026, providing a solid raw material base for melt direct spinning.
The difference between melt direct spinning and traditional chip spinning lies in process reengineering. The self-developed technology eliminates intermediate steps such as chip packaging, warehousing, and transportation, enabling continuous polymerization and spinning. Industry data indicates that this process reduces water consumption by about 80% and electricity consumption by 30%, while significantly lowering pollutant emissions. These metrics are not just environmental; they are cost-related, as the reduction of intermediate steps directly lowers labor and logistics costs per unit.
From an industrial cluster perspective, the dual-location layout in Guangxi and Hangzhou has differentiated significance. Guangxi, close to raw materials and energy sources, suits large-scale chip production; Hangzhou, near downstream weaving and consumer markets, facilitates rapid response to fabric demand. This 'raw material plus market' dual-point arrangement allows the company to allocate resources across regions and reduce operational risks.
Industry Impact
For nylon fabric buyers, the most direct impact of melt direct spinning is improved quality consistency and supply stability. Traditional chip spinning often causes dyeing uniformity issues due to batch variations; melt direct spinning, with continuous polymerization-to-spinning, results in a narrower molecular weight distribution, better yarn strength, and improved dyeing performance. This means the risk of quality fluctuations when sourcing high-end nylon fabrics will significantly decrease.
Cost changes are equally noteworthy. An 80% reduction in water use and 30% in electricity will eventually reflect in yarn prices. When leading players like Hengyi produce PA6 fibers at lower costs, market pricing power may shift further toward integrated companies. Smaller spinning mills that fail to adopt technological upgrades may find themselves at a competitive disadvantage.
From an industry trend perspective, Hengyi's move is not isolated. The chemical fiber sector is accelerating toward high-end, green, and low-carbon transformation. PA6, as a high-performance fiber material, has become a core track for leading enterprises to build new growth curves. Hengyi's simultaneous efforts in both polyester and nylon, with this project filling the key gap from chip to spinning, complete its integrated layout. The combination of 'raw materials + technology + capacity' is reshaping industry entry barriers.
For textile trading companies, changes in the nylon fabric supply landscape will transmit to export pricing. Integrated companies, leveraging cost advantages, may offer more competitive FOB prices; meanwhile, the low-carbon attributes of green processes help meet Western buyers' requirements for sustainable supply chains. However, caution is needed: increased capacity concentration may reduce buyers' bargaining power, requiring more careful design of long-term contract price terms.
