【Product Characteristics】
1、Moisture absorption and quick drying to improve fabric comfort
The moisture absorption and moisture discharge performance of PA56 as clothing fabric is 1.5 times as that of PA 66 and 2 times as that of PA 6.
2、Excellent wear resistance
The wear resistance of PA56 is 10 times higher than that of cotton, 20 times higher than wool and 50 times higher than viscose fiber。Adding PA56 to the blended fabric can greatly improve its wear resistance, prolong its service life and reduce its use cost.
3、Excellent elasticity
The elastic recovery of PA 56 is better than that of PA 66, which is much higher than that of polyester. When stretched to 3 ~ 6%, the elastic recovery rate can reach 100%. It can be blended with wool or cotton to improve the wrinkle resistance of the fabric. When applied in carpet, it has better fatigue resistance and lodging resistance，instead of polyester.
4、Good flame retardancy and easy coloring
PA56 is non flammable and has superior flame retardant performance compared with similar products; PA 56 is easy to dye, fixation and high color fastness.
5、Environmental friendly
Due to the increasingly severe climate change and sustainable development needs in the world, PA 56 has attracted extensive attention from the upstream and downstream textile industry chain because of its 48% bio base content and it has the conception of low-carbon and environmental protection. Bioamylenediamine uses corn as raw material, and the renewable carbon content is 100%. The carbon emission of nylon 56 produced with amylenediamine is more than 50% lower than that of traditional PA 6 and PA66.
【Product Description】
PA56 crystal is produced from PDA and adipic acid. PA 56 chips produced by polymerization can be widely used in spinning、fabric fields (Civil and military) and engineering plastics.
