The Lenzing Group, a leading supplier of regenerated cellulosic fibers for the textile and nonwovens industries, ROICA by Asahi Kasei, a pioneer in premium stretch fiber, and Kaihara Denim, the world-renowned Japanese denim manufacturer, join forces for the first time to co-create a premium stretch denim collection, “SAISEI Collection.” The strategic partnership is well-placed to offer the international market a higher composition of recycled materials in denim. Blending LENZING ECOVERO branded viscose fibers with REFIBRA technology1 with ROICA EF recycled stretch yarn and entrusting them with Kaihara Denim’s renowned denim craftsmanship, the high-quality denim collection is brought to light. It will make its first appearance at Kingpins Amsterdam, October 23–24, 2024.
“Through this partnership with Kaihara Denim and ROICA by Asahi Kasei, we are taking bold steps to drive denim circularity4 empowered by joint expertise and devotion,” said Dennis Hui, Global Business Development Manager, Denim at Lenzing. “The synergy between ROICA EF yarn, LENZING ECOVERO fibers with REFIBRA technology, and Kaihara Denim’s exceptional craftsmanship has given life to premium, resource-efficient1 denim fabrics that have sustainability, performance, and style at heart.1,4,5 This partnership not only underscores the shared commitment between Lenzing and our partners to create excellent products while doing better for the environment4 but also serves as a catalyst for driving the transformation towards low-impact practices4 across the denim value chain and beyond.”
Weaving the future of denim with collective innovation
The new denim collection boasts a special fabric composition, making the most of ROICA EF yarn and LENZING ECOVERO fibers with REFIBRA technology thanks to their resource-efficient1,4,5 attributes. ROICA EF, made of pre-consumer recycled content as well as featuring excellent stretchability2, is integral to the flexibility, and comfort of the fabric. On the other hand, LENZING ECOVERO fibers with REFIBRA technology comprises up to 20% of post-consumer textile waste, which is sourced from cellulose-rich materials or polyester-cotton blends, supporting natural softness to the denim fabric.
“Our vision for sustainability at Asahi Kasei is to achieve zero emissions and seek to recycle all of our industrial waste,” said Hiroaki Shinohe, Chief Marketing Officer of ROICA Europe at Asahi Kasei. “Our innovative ROICA EF yarns, which is 30% lower in CO2 emissions compared to regular yarns5, exemplify this dedication. By partnering with Lenzing and Kaihara Denim on a recycling concept that gives new life to pre-used materials, we are able to leverage our collective expertise in sustainable stretch fabrics. We are thrilled that the incorporation of LENZING ECOVERO with REFIBRA technology and Kaihara Denim’s premium denim craftsmanship can provide an exceptional fabric that meets the growing consumer demand for environmentally consicous1,4,5, comfortable denimwear.”
Redefining denim applications for high-performing, eco-conscious fashion
The collection offers three distinct denim fabrications – super stretch (Monster Stretch by Kaihara Denim), comfort stretch, and low stretch (selvage denim) – each crafted with Kaihara Denim’s artisanal expertise using the meticulous blend of LENZING ECOVERO with REFIBRA technology and ROICA EF. This innovative denim fabric features a subtle bulkiness and reduced drape, delivering a unique hand feel. The versatility of the new denim fabric opens a world of possibilities for fashion designers and brands, empowering them to create stylish, resource-efficient1,4,5 garments that range from everyday chic, casual wear to workwear.
“As Lenzing’s long-standing partner, we are thrilled to be part of this transformative journey with ROICA by Asahi Kasei that embodies our concerted efforts towards driving positive change across the global denim landscape,” said Hirofumi Inagaki, Executive Officer, General Manager of Sales Department at Kaihara Denim. “Our long history and established expertise in premium denim manufacturing allow us to unlock the full potential of LENZING ECOVERO with REFIBRA technology and ROICA EF, resulting in this innovative, resource-efficient1,4,5 denim collection. Together, we are reshaping the future of sustainable denim applications, both casual and formal, paving the way for a more circular fashion value chain.”
