Core Viewpoint - China National Petroleum Corporation (CNPC) has achieved significant breakthroughs in high-performance fiber technology, with two new products developed by Daqing Petrochemical and Jilin Petrochemical, filling domestic market gaps and enhancing product offerings [1]. Group 1: Daqing Petrochemical's New Fiber Product - Daqing Petrochemical has successfully developed the DGF-K fiber, becoming the first company in China to do so, which fills a domestic gap and lays a foundation for future production scaling and market promotion [2][3]. - The DGF-K fiber retains far-infrared functionality, UV resistance, and excellent electrical, thermal, and mechanical properties while overcoming pilling issues. It has a 99% antibacterial rate against Staphylococcus aureus and Escherichia coli, with a pilling resistance rating of 4 [3]. - The new fiber will be used in bedding and autumn/winter clothing materials, enhancing the product line and meeting downstream customer needs [2][3]. Group 2: Jilin Petrochemical's Carbon Fiber Technology - Jilin Petrochemical has developed a high-strength large tow carbon fiber production technology, which has been recognized as mature and meets international advanced standards for T700-grade large tow carbon fiber, filling a domestic product gap [4]. - T700-grade carbon fiber offers higher production efficiency and lower unit costs compared to smaller tows, making it suitable for large-scale industrial applications and improving production speed for large composite materials [5]. - This carbon fiber meets the strength requirements for aerospace components and high-end composite structures while balancing performance and cost, with applications in wind turbine blades, sports equipment, automotive parts, and pressure vessels, indicating a broad market potential [6].
