Bioworks Corporation in Japan announced the first commercial launch of its plant-based synthetic fiber “Plax,” modified from PLA using Bioworks’ proprietary technology, across two Goldwin Inc. brands: THE NORTH FACE and NEUTRALWORKS.
Since 2022, Bioworks and Goldwin have been collaborating on the product development of PlaX and starting with Goldwin’s 2025 Fall/Winter collections for THE NORTH FACE and NEUTRALWORKS, outerwear made from PlaX-based pile fleece is now available.
In preparation for commercialization, both companies carried out an extended period of prototyping and testing. To meet Goldwin’s high-quality standards—particularly regarding dyeability and durability, they collaborated to review yarn processing conditions and design, working closely with textile manufacturers and dyeing facilities to conduct repeated tests and continuously refine the material. Through these sustained efforts to enhance quality, preparations for practical use were conducted over approximately three years, ultimately leading to the material’s adoption.
Moving forward, both companies will continue to deepen collaboration in material development and product design, aiming to accelerate sustainable manufacturing. Through the expanded adoption of PlaX, Bioworks aims to contribute to reducing the environmental impact of the fashion industry and promoting a circular economy.
