(Headquarters: Soraku-gun, Kyoto Prefecture, Representative Director, President and CEO: Koji Sakamoto, hereinafter “Bioworks”) is Nittobo Advantex Co., Ltd. (Headquarters: Itami City, Hyogo Prefecture, Representative Director: Tetsuya Mori, hereinafter “Nittobo We have jointly developed a filament (long fiber) type of “Double Dot Adhesive Core” using PlaX, a next-generation plant-based synthetic fiber made from polylactic acid (PLA). This is the first attempt to develop an adhesive interlining that uses PlaX filament as an interlining. With this development, it is possible to apply this technology to a wider range of clothing than the previous development of adhesive interlining for spun (short fiber) interlining, and is expected to contribute to reducing the environmental impact of the fashion industry and realizing a recycling-oriented society. Background of the development of “double dot adhesive core” using PlaX filament Bioworks and Nittobo Advantex have been working on joint development of adhesive interlining since 2022, and in January 2024, they developed a “double dot adhesive interlining” using PlaX spun yarn and an adhesive using polylactic acid. We have now succeeded in developing a filament type that has been highly requested by the market, and have completed a 75 denier PlaX 100% filament interlining. The development of filaments requires precise control of fiber uniformity during spinning and raw material viscosity, and high technical hurdles existed for biopolymers such as polylactic acid, which have difficulty controlling thermal stability and viscosity. By solving these issues with Bioworks’ development technology and making it possible to produce filament with stable quality and physical properties, we were able to develop a double-dot adhesive core using filament PlaX. Adhesive interlining is one of the auxiliary materials, and by applying adhesive to the base fabric that serves as the interlining and attaching it to the outer material during sewing, it plays the role of reinforcing the fabric and maintaining its shape. In recent years, while the development of plant-derived materials has progressed mainly for outer materials, there have been few examples of developments in adhesive interlining, and petroleum-derived materials such as polyester for base fabrics and polyamide and polyester for adhesives still occupy the majority of the market. PlaX, a
next-generation plant-based synthetic fiber researched and developed by Bioworks, is a biodegradable biomass material that undergoes hydrolysis under industrial compost and ultimately decomposes into water and carbon dioxide. In addition, chemical recycling
demonstration experiments are currently underway to take advantage of its properties and regenerate and reuse the raw material polylactic acid from PlaX products. Since adhesive interlining is used in various parts of clothing, the development of interlining using PlaX is expected to contribute to decarbonization and resource recycling in the fashion industry.

Furthermore, as a result of LCA (life cycle assessment) analysis, PlaX filament has been proven to be effective in reducing CO2 emissions by approximately 70% compared to general polyester, contributing to reducing environmental impact as an alternative to conventional materials. In the future, Bioworks will continue to collaborate with Nittobo Advantex to further joint research and develop sustainable auxiliary materials with less environmental impact.

It is attracting attention around the world as a versatile material and an alternative to petroleum-derived synthetic fibers such as polyester. 《Features of PlaX》 ・Compared to polyester, by replacing with PlaX, CO2 emissions from manufacturing long fibers are reduced by 70%, and CO2 emissions from manufacturing short fibers (raw cotton) are reduced by 50%. ・90% less water usage from raw material to yarn manufacturing compared to cotton. ・A material with the characteristic of
“biodegradability” that is broken down into water and CO2 by microorganisms. ・It is compatible with chemical recycling, which reproduces equivalent materials from waste, and research and development is progressing toward the realization of a closed loop that circulates resources. ・Reduced CO2 emissions during incineration. No harmful substances such as dioxins are generated. Nittobo Advantex Company Profile ■ Nittobo Advantex Co., Ltd.
