A polyamide (PA) fiber that incorporates 100 bio-based synthetic polymer content has been developed by Toray. Ecodear N510, will be the first 100 plant-based PA fiber in Toray's Ecodear portfolio. The company has created diverse potential applications for Ecodear N510 as a sustainable offering for high-end markets. While primarily for sports and outdoor fabrics they extend to lightweights, cut-and-sew fabrics through innerwear lace materials. Toray Industries, Inc., Tokyo/Japan, already offers partially plant-based polyester (PET), PA, and other polymers. It developed Ecodear N510 by polymerizing Sebacic acid from castor-oil plant and Pentamethylenediamine from corn and spinning. Unlike other wholly plant-based PAs, the new fiber has a high melting point and outstanding dimensional stability. It is as strong and heat-resistant as PA6. Companies can thus create products that are sustainable without compromising performance.
