 Toray Industries, Inc., 

Tokyo, Japan, January 14, 2022 – Toray Industries, Inc., announced today that it has developed a nylon 510 (N510) fiber that incorporates 100% ‘biobased synthetic polymer content’ as defined under section 3.1.5 of ISO 16620-1: 2015, the international standard for the biobased content of plastics.  Ecodear™ N510, will be the first 100% plant-based nylon fiber in Toray’s Ecodear™ lineup. 

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 plans to begin Ecodear™ N510 textiles sales for fall/winter 2023. Initial production volume to be 200,000m by the end of March 2023 and growing to 600,000m in March 2026. Ecodear™ N510 fiber sales are targeted for fall/winter 2024 with an expectation of a monthly supply of 3 metric tons monthly in the year ending March 2024. 

Nylon originated in the United States. In the early 1950s, Toray became the first Japanese company to manufacture nylon. Apparel and other wide-ranging applications over the years have reflected nylon’s excellent flexibility, durability, wrinkle resistance, and washability. Nylon is typically made from petroleum. In light of rising demand in recent years for environment-conscious products to address such global environmental issues as resource depletion and global warming and address a growing awareness of the need to build a sustainable society. 

Toray already offers partially plant-based polyester, nylon, 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 nylons, Ecodear™ N510 has a high melting point and outstanding dimensional stability. It is as strong and heat-resistant as Nylon 6. Companies can thus create products that are sustainable without compromising performance. 

Toray looks to combine various proprietary technologies to drive further fiber advances. These would include making fibers thinner and lighter or adding functionality by changing cross-sectional shapes. The company will develop an array of apparel and other materials applications to help building a sustainable society.

Under its sustainability vision, Toray has pledged to offer innovative technologies and advanced materials that provide real solutions to the international community’s myriad challenges in balancing development and sustainability.

Ecodear™ N510 represents part of the Toray Group’s efforts to help attain carbon neutrality by 2050, and should contribute to resolving environmental issues all over the world. Through its endeavors, Toray will keep serving increasingly diverse lifestyles while contributing to affluent living and sustainability.
