About Yizheng Chemical Fiber

In 2007, Yizheng Chemical Fiber included the "Development of Complete Dry Spinning Technology for 300 Tons/Year High-Performance Polyethylene Fiber" in the Sinopec Science and Technology Innovation "Ten Dragons"攻关 project, collaborating with institutions such as the China Textile Academy to carry out industry-academia-research协同攻关.By breaking through the core technologies of dry spinning processes, a production line with a capacity of 300 tons/year was established in 2008, and by 2011, it achieved industrialization with a capacity of 1,000 tons/year, making it the third company globally to master this technology.This breakthrough has broken the technological blockade of companies like Dutch DSM and American Honeywell, shifting China's UHMWPE fiber from import dependence to self-control. The product strength has reached an internationally advanced level, laying the foundation for subsequent industrial upgrades.

Relying on the advantages of dry spinning technology, Yizheng Chemical Fiber continues to expand its production capacity. After the commissioning of the third thousand-ton production line in 2018, the total capacity increased to 2,300 tons per year, and the domestic market share reached 20%.By 2024, its UHMWPE fiber production capacity has reached 3,300 tons per year, making it the only domestic large-scale production enterprise using the dry process.In the Yangzhou Chemical Park, companies achieve full-process collaboration from PTA raw materials to fiber products through in-depth coupling of the olefin and aromatics产业链布局. The 300 million tons/year PTA project scheduled for production in 2025 will provide a stable supply of raw materials for fiber production.Forming an industrial ecosystem that integrates "technology-capacity-raw materials" as a trinity.

Yizheng Chemical Fiber's UHMWPE fiber, centered on the "Lilan" brand, has achieved breakthroughs in the military sector. Its ballistic-grade fiber is used in national defense equipment such as new fighter jets and aircraft carrier deck protection, while also developing civilian products like cut-resistant gloves and thermally conductive textiles.In the field of major engineering projects, the installation of the 6,000-ton immersed tunnel for the Hong Kong-Zhuhai-Macao Bridge utilized 140,000 fiber slings, with each filament bearing a load of up to 35 kilograms, demonstrating the reliability of materials in extreme environments.In 2023, the global UHMWPE fiber production capacity was approximately 67,000 tons. Yizheng Chemical Fiber's products achieved a penetration rate of 32% in the bulletproof field and are gradually expanding into emerging markets such as offshore wind power ropes and deep-sea aquaculture cages.

Yizheng Chemical Fiber uses UHMWPE fiber as a pivot to promote the vertical extension of the high-performance synthetic materials industry chain. Upstream, it achieves self-sufficiency in raw materials through a 3 million tons/year PTA project; midstream, it has laid out a flexible production line for 120,000 tons of PBT/PBAT biodegradable materials; and downstream, it is developing high-end products such as TPEE elastomers. In the Yangzhou Chemical Park, the company has formed an industrial closed loop of "olefins-aromatics-fine chemicals," driving the development of related industries such as ethylene oxide and polyether polyols, generating over 10 billion yuan in annual upstream and downstream output value. This full-chain synergy of "materials-products-applications" positions it to become the leading enterprise in Yangzhou's high-performance synthetic materials industry chain in 2024.

Faced with global competition in the new materials industry, Yizheng Chemical Fiber has formulated a development strategy of "technology leadership and low-carbon transformation." In terms of technology, it continues to invest in R&D for high-end products such as heat-resistant and creep-resistant fibers and carbon nanotube-reinforced fibers. In 2024, the TPEE elastomer used for railway track pads broke the monopoly held by foreign companies, earning a provincial science and technology innovation achievement award. In terms of green development, the new-generation bottle chip production line adopts a short-process technology, reducing carbon emissions by more than 20%. At the same time, the company actively responds to national export control policies, reinforcing technical barriers for its products in the international market. In the first half of 2024, it exported 4,000 tons of customized film-grade polyethylene terephthalate chips to Japan, demonstrating the international competitiveness of high-end materials. In the future, Yizheng Chemical Fiber aims to achieve the goal of "domestic leadership and world-class standards," continuously expanding into areas such as marine engineering and aerospace, driving China's high-performance fiber industry to ascend towards the high-end of the value chain.
