Bio-based aramid is a high-performance synthetic fiber prepared from renewable biomass resources, such as corn syrup, fructose, glucose, etc. Replacing traditional petroleum-based raw materials with renewable biomass resources, bio-based aramid has greatly reduced the reliance on fossil resources.

Aramid, the full name of which is aromatic polyamide fiber, mainly includes para-aramid, meta-aramid, etc. Aramid technology is highly challenging and requires high-quality production equipment. The global production capacity is relatively concentrated, with producers including DuPont of the United States, Teijin of Japan, Kolon of South Korea, Hyosung of South Korea, and Taihe New Materials, among others. In recent years, the production capacity of aramid in China has grown rapidly, and the imbalance between supply and demand in the market has gradually become prominent. Against this backdrop, the aramid industry has gradually shown new trends of high-end, green and differentiated development.

Furthermore, under the bioeconomy, bio-based fibers have become a strategic industry in countries such as Europe, the United States, Japan and South Korea. China also supports the development of the bio-based fiber industry. In recent years, the production capacity of the bio-based fiber industry has been continuously increasing and is expected to reach over 1.5 million tons in 2024. As a high-performance fiber material, the bio-based aramid market has also attracted a number of enterprises to make strategic layouts. At present, the enterprises in China that have made layouts in bio-based aramid include Liko New Materials and Taihe New Materials, etc.

Among them, Taihe New Materials was the first to introduce bio-based aramid and recycled aramid in 2023. Liko New Materials' technology originated from the University of Science and Technology of China - Anhui Provincial Key Laboratory of Biomass Clean Energy. It has a bio-based aramid polymerization production base in Jiaxing and a bio-based aramid coating engineering center in Liyang. Currently, it has a 4,800-ton bio-based aramid slurry production line, a 1GWh oil-based aramid coated separator production line, and a 2GWh water-based aramid coated separator production line.

Bio-based aramid has advantages such as high strength, low carbon emissions and degradability. It can be used to prepare bio-based aramid coated separators, bio-based aramid adhesives, bio-based aramid paper and other products, and further applied in fields such as lithium batteries, safety protection, rail transit, electrical insulation and aerospace.

At present, lithium battery coated separators are the main application scenarios of bio-based aramid. Bio-based aramid coated separators are a new type of lithium battery separator, including bio-based aramid oil-based coated separators, bio-based aramid water-based coated separators, bio-based aramid nanoparticle coated separators, and bio-based aramid nanofiber coated separators, etc. Aramid coated separators are an important direction for the upgrade of lithium battery separators. Bio-based aramid coated separators have green and environmentally friendly characteristics and have greater market development potential.

Under the green and high-end transformation of the aramid industry, bio-based aramid has become an important development direction in the market. In addition, the favorable policy environment for the bio-based fiber industry has further promoted the development of the bio-based aramid industry. The "2024 Compilation of Green and Low-Carbon Technologies in the Textile Industry" was jointly compiled by the Science and Technology Development Department of the China National Textile and Apparel Council and the Social Responsibility Office of the China National Textile and Apparel Council. The "Research and Development and Industrialization of Bio-based Aramid Technology" was included in it, further affirming the innovative value of bio-based aramid.
