Bioworks Corporation is pleased to announce that its next-generation plant-based synthetic fiber, PlaX^TM, has been adopted by Seivson, a Taiwanese designer brand that is gaining attention across Asia, for its 2025 Spring/Summer collection. On Wednesday, September 4, 2024, five designs featuring PlaX^TM were unveiled at the Rakuten Fashion Week TOKYO runway show.

Background of PlaX^TM Adoption

PlaX^TM is a plant-based synthetic fiber made from sugarcane. It is a new material that contributes to addressing environmental issues such as resource depletion and carbon dioxide emissions by replacing petroleum-based synthetic fibers. PlaX^TM was selected because its environmental contribution and fabric texture align with the theme of Seivson’s 2025 Spring/Summer collection and the brand’s commitment to sustainable fashion. With this adoption by an international brand, Bioworks will accelerate its global market expansion and focus on building further partnerships. We will continue to actively pursue collaborations with new brands and designers to promote the adoption of sustainable fashion materials.

Seivson 2025 Spring/Summer Collection Theme: “TRACES”

“Scars are the history of the body, and wrinkles are the traces of clothing.”

Seivson’s 2025 Spring/Summer collection is themed “TRACES.” This series explores modern social phenomena experienced in the new era of the internet, from the perspective of a woman’s body growth. The designs reflect the inextricable contradictions and distortions between reality and falsehood.

Comment from Designer Tzu Chin Shen

During the design process, it became clear that the texture and characteristics of PlaX^TM were a perfect match for this season’s theme, “Scars are the history of the body, and wrinkles are the traces of clothing.” Just as the traces left by a woman’s body during its growth reflect modern societal phenomena, the details and texture of PlaX^TM faithfully embody our thoughts on growth and are expressed in the works.
