Chinese petrochemical producer Hengyi Petrochemical announced on August 10 plans to construct a 400,000-tonne annual capacity polyamide 6 (PA6) melt direct spinning project. Executed through its wholly owned subsidiaries Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, the initiative represents a total investment of RMB 4.87 billion.
Financed through self-owned and raised funds, the project was unanimously approved by the company's Board of Directors.
Production Mix and In-House Direct Spinning Technology
With a 18-month construction timeline, the project's product portfolio comprises 220,000 tonnes of fully drawn yarn (FDY) and 180,000 tonnes of draw textured yarn (DTY) per year.
The facilities will deploy Hengyi Petrochemical's self-developed PA6 melt direct spinning process. By integrating traditional polymerization and spinning operations into a single continuous process, the technology reduces energy consumption, raw material loss, and water usage while minimizing site footprint and capital expenditure.
Subsidiary Infrastructure and Regulatory Roadmap
Guangxi Hengyi New Materials currently operates a 600,000-tonne annual PA6 chip production base, maintaining high capacity utilization throughout 2026. Hangzhou Yizhijin New Materials was incorporated in March 2026 to focus on synthetic and high-performance fibers.
While approved at the board level, implementation remains subject to standard regulatory filings, including environmental impact assessments and energy efficiency evaluations.
