The bio-based PA56 industry has good development prospects, but it is still in the early stages of industrial development.

Bio-based PA56 is a new type of bio-based polyamide produced by the polymerization of bio-based pentanediamine and petroleum-based adipic acid. Bio-based pentanediamine is obtained through starch microbial fermentation, which not only reduces the production cost of PA56, but also solves the problem of solve the problem of oil resource shortage. Bio-based PA56 has good solvent resistance, high strength, and outstanding thermal stability. It also has excellent hygroscopicity, softness, and low-temperature dyeability, and has good application prospects in the field of prevention and control.

According to different application fields, bio-based PA56 fiber can be divided into six categories: clothing filament, carpet yarn, monofilament, composite functional fiber, industrial yarn, and short fiber. Among them, industrial yarn has impact resistance and good wear resistance. , high strength, can be used in the production of safety belts, conveyor belts, airbags, cord fabrics, parachutes, canvas and other products. Current industrial yarn manufacturers include Japan Toray Co., Ltd., Jiangsu Taiji Industrial New Materials, etc. According to different forms, bio-based PA56 fiber is divided into filament, air-textured yarn, and staple fiber yarn. The filament includes stretch-textured yarn, fully drawn yarn and other products.

According to the “Bio-based PA56 Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2021-2025” released by the Industrial Research Center, Bio-based PA56 fiber has a wide range of applications and can be used in civil and industrial fields, such as cord fabrics, airbags, canvas, etc. In special application fields, it can be used in high-strength protective clothing, tents, etc., which can meet the requirements of special military equipment and improve combat effectiveness. In addition, bio-based PA56 fiber also has great room for development in the engineering plastics industry and can be used in transportation, electronics, high-speed rail, mechanical bearings and other products.

In addition, the use of biological methods to produce pentanediamine reduces costs, improves production efficiency, and reduces carbon emissions during the production process. In practical applications, using one ton of bio-based PA56 fiber can save 160 liters of crude oil and reduce carbon dioxide emissions by about 7 tons.

In terms of production, after years of research and development, Shanghai Cathay Biotechnology Co., Ltd. has broken through the key technology of biological production of pentanediamine, and successfully developed bio-based PA56 fiber with a bio-based content of up to 49% using bio-based pentyl diamine. In 2018, a bio-based PA56 production base with an annual output of 100,000 tons was established in Wusu, Xinjiang.

Industrial analysts said that bio-based PA56 has a wide range of applications and has environmentally friendly properties. It can also break down the use of hexamethylenediamine by foreign countries. The corporate monopoly structure helps alleviate the country’s high dependence on oil. Therefore, the development value is high and the industry development prospects are good. In actual production, the current bio-based PA56 has not yet been mass-produced and applied. There are still technical difficulties in the industrialization process. The stability of the currently produced bio-based PA56 products is not high, which limits the development of the industry.
