Creating a Zero Carbon Emission Fiber Industry with ZERO-TEXⓇ

ZERO-TEX® is a sustainable fabric material developed by Yamagin Inc. in 2021, designed to be environmentally friendly and gentle on both people and the planet. Originally introduced for medical gowns, the technology has evolved, now reaching its third generation. One of its key features is the use of a unique spinning technique, which has enhanced the strength and sustainability of the fabric. The manufacturing process has successfully reduced CO2 emissions by 52% and water usage during the dyeing process by 70%, as compared to in-house comparisons.

This multi-functional material caters to various applications, from everyday life to outdoor activities, medical settings, and uniforms. Notably, it boasts “durable water repellency,” a functionality that remains intact even after 100 washes, independently certified by third-party organizations.

In terms of water repellency, the material has been designed to minimize environmental impact without relying on harmful water repellents. Additionally, thoughtful engineering maintains breathability while providing water resistance.

Moreover, it is produced in PENFABRIC SDN. BERHAD, a manufacturing facility that has obtained the highest level of safety certification worldwide (“MADE IN GREEN by OEKO-TEX®“). Therefore, users can trust and feel secure about its sustainability.

BIOTECHWORKS-H2, a subsidiary of Yamagin Inc. (CEO/Founder: Akihide Nishikawa), has been building a platform that utilizes ZERO-TEX® alongside the development of a watermarked system for post-use apparel products. The platform aims to connect production processes, end-users, companies, and hydrogen plant businesses and plans to facilitate direct transactions between them through blockchain technology.

In alignment with these efforts, they have embarked on activities related to “realizing a decarbonized society, reducing environmental impact, and decarbonizing the textile industry.” This initiative is referred to as the “ZERO-TEX® Carbon Neutral Declaration,” and its promotion primarily involves public appearances and book publications.

While interest and collaboration from the community are certainly increasing, the resolution of these challenges requires the creation of a more substantial societal wave to address environmental issues effectively.
