What is Nylon Bio-based Fabric?What is the difference between nylon based PA56 and regular nylon?

2023-09-06 | Introduction to Tactical Products

Under the trend of low-carbon environmental protection, bio based materials have gradually become an important part of sustainable development:


▶ According to the US Biomass Technology Roadmap, by 2030, bio based chemicals will replace 25% organic chemicals and 20% petroleum fuels;

▶ According to the EU's "Industrial Biotechnology Vision Plan", by 2030, bio based raw materials will replace 6% -12% of chemical raw materials and 30% -60% of fine chemicals will be manufactured from bio based materials;

▶ China plans to achieve a future output value of over 1 trillion yuan in the modern biological manufacturing industry, with biological based products accounting for 25% of all chemical production.

The global nylon market is approximately 10 million tons. Except for some special types of nylon, the proportion of bio based nylon products is very low. Bio based nylon 56 or nylon 5x has the opportunity to replace some bulk nylon markets due to their comprehensive advantages in performance, cost, etc. If replaced by 5%, there will be a market size of 500000 tons.


Nylon bio based: PA56 is a polyhexamethylene diamine formed by the polymerization of bio based pentanediamine and petroleum based adipic acid. It is named after the fact that pentanediamine has one carbon atom less than hexamethylene diamine in PA66.


Compared with PA66, PA56 contains unsaturated hydrogen bonds, retaining its biological "activity"; The unique Young's modulus value of the material can scientifically adjust the tactile feel of the fabric, providing strong, tough and wear-resistant properties, while endowing it with a natural and smooth touch, with excellent drapability; At the same time, the "active" structure in the molecular chain gives it the ability to absorb water faster and transmit heat to the outer side of the fabric, which can maintain a cool body feel even when worn for a long time.

There are significant differences between nylon based PA56 and ordinary nylon, with the following specific differences:


The raw materials are different. Nylon bio based PA56 is polymerized from bio based pentanediamine and petroleum based adipic acid; Ordinary nylon is formed by polymerization of adipic acid and adipic amine.


Different performance characteristics. Nylon bio based PA56 is lightweight, has good softness, and has good low-temperature resistance; Ordinary nylon has wear resistance, good resilience, and high mechanical strength.


In addition, nylon based PA56 is more environmentally friendly than regular nylon.

That's why more and more people are choosing to use nylon bio based fabrics.
