While most nylon producers still compete on scale within the traditional chip-and-spin route, Hengyi Petrochemical has shifted the competitive dimension to a technological generation gap with its 4.87 billion yuan investment announcement. The 400,000-tonne PA6 melt direct spinning project cuts water use by 80% and electricity by 30%, implying a cost reduction of hundreds of yuan per tonne, enough to reshape profit distribution in the mid-to-low-end nylon market.
Background
The project will be implemented at two bases in Guangxi and Hangzhou, through subsidiaries Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, with an 18-month construction period and funding from internal and external sources. Notably, Guangxi Hengyi's existing 600,000-tonne PA6 chip plant will run at full capacity in 2026, providing a stable feedstock base for the melt direct spinning line, giving the new project a self-sufficiency advantage from the outset.
The self-developed melt direct spinning process eliminates intermediate steps such as chip packaging, warehousing, and transportation. This is not just a simplification but means factories can significantly reduce work-in-progress inventory and logistics costs. For buyers, supply chain responsiveness will improve markedly, and order lead times may shorten—all stemming from the shift away from traditional batch chip spinning.
Industry Impact
The essence of Hengyi's move is a value leap from 'selling chips' to 'selling fibers.' Previously, chip prices fluctuated with crude oil, leaving limited pricing power. Now, by extending downstream to spinning, the company can directly serve fabric and apparel customers, capturing higher added value. This strategic pivot signals that the nylon track is shifting from capacity competition to technology and integration capabilities.
For regional industrial clusters, the nylon hubs in Guangxi and Hangzhou will strengthen through this project. The Guangxi base, near feedstock and energy sources, suits large-scale chip production; the Hangzhou base, close to downstream markets and R&D resources, enables rapid response to customer needs. This dual-point layout may prompt other chemical fiber leaders to reassess their own base configurations.
At the industry level, the energy-saving advantages of melt direct spinning align with dual-carbon policy directions. As environmental standards tighten, early adopters of new processes will gain compliance cost advantages. Moreover, reduced water and electricity consumption directly lower production costs, building a cost moat for Hengyi amid fierce nylon price competition.
