(2) Market prospect of the project
In recent years, with the continuous deepening of related research and the gradual improvement of production technology and the production capacity of PA56 in China has gradually increased. Currently, China’s biobased PA56 has successfully achieved commercialization. The commercial production of PA56 has opened up a new path for the development of the bottleneck polyamide industry. The structure of PA56 is similar to that of PA66, and its performance in wear resistance, flame retardancy, moisture absorption, and strength is superior to PA66. With the upgrading of downstream market demand, PA56 has greater market development potential in the future. In recent years, with the continuous deepening of research, the number of research projects and patents related to PA56 has grown rapidly. Meanwhile, the market recognition of PA56 has gradually increased.
According to market research institutions’ predictions, the market size of biobased polyamide 56 fibers will rapidly grow at an average annual compound growth rate of over 15% during 2020 - 2024. This growth trend is mainly due to the superior performance and expanding application areas of PA56 material. Especially in the context of increasingly strict environmental requirements, biobased polyamide 56 fiber, as a biodegradable and environmentally friendly material, has received widespread attention and favor.
It is expected that by 2030, with the continuous advancement of technology and further cost reduction, the market size of biobased polyamide 56 fibers will achieve greater breakthroughs. At that time, the material will not only continue to grow in traditional fields such as textiles, instruments, and food packaging films, but also show broad application prospects in more emerging fields such as new energy vehicles and environmentally friendly building materials. This will bring unprecedented development opportunities for the biobased polyamide 56 fiber industry.
There are currently 14 textile and clothing enterprises and 7 electronic equipment manufacturing enterprises in Tumen Border Cooperation Zone. The implementation of this project is highly compatible with the three emerging industries (fine chemicals, commercial logistics, cultural tourism and health care) and four leading industries (electronic equipment, clothing and footwear, mineral construction, medicine and food) developed by Tumen City, which can help the industrial transformation and upgrading of the Park and promote high-quality economic development of the Park.
1.1.3 Technical analysis
The preparation process of biobased polyamide 56 fiber mainly includes the following steps:
Salt formation reaction: Firstly, adipic acid and pentanediamine are salted in an aqueous solution to prepare a PA56 salt solution. This step is the basis for preparing PA56 slices.
Aggregation reaction: Under certain temperature and pressure conditions, PA56 salt solution is pre polymerized, pre polymerized, and finally polymerized to obtain PA56 slices. During this process, by controlling the reaction conditions, the smooth progress of the polymerization reaction is ensured, resulting in the formation of high-quality PA56 slices.
Spinning: The obtained PA56 slices can be processed into PA56 fibers through melt spinning. Furthermore, PA56 slices can also be used for processing into plastic products.
Preparation method of biobased polyamide 56 fiber:
High stability biobased polyamide 56 fiber: The preparation method of this fiber includes using high stability biobased polyamide 56 as raw material, with a relative viscosity of 2.2-3.6, terminal amino content of 30-65 meq/kg, and TiO2 content of 0% -2% of the fiber weight. This fiber has good spinnability and aging resistance.
Flame retardant polyamide 56 fiber: A flame retardant is prepared by the salt formation reaction of biobased itaconic acid and pentadiamine, followed by addition with the intermediate DOPO of phosphorphine. Finally, the biobased flame retardant polyamide 56 is prepared by one-step melt condensation. This flame retardant has good thermal stability and water solubility, ensuring high activity and homogeneous reaction in high-temperature copolymerization.
