Nittobo Advantex, in Collaboration with Bioworks, Announces the Development of the Industry's First"Biodegradable Double Dot" Adhesive Interlining, Advancing Closed-Loop in the Fashion Industry
Nittobo Advantex Co., Ltd. (Headquarters: Itami-shi, Hyogo, hereinafter "Nittobo Advantex"), a wholly
owned subsidiary of Nittobo, in collaboration with Bioworks Co., Ltd. (Headquarters: Soraku-gun, Kyoto,
hereinafter "Bioworks"), has jointly developed the industry's first "biodegradable double dot" adhesiveinterlining.
Background of the Development of "Biodegradable Double Dot" Adhesive Interlining
As sustainability becomes a growing concern in the fashion industry, there has been a development ofmaterials with biodegradability or compostability, primarily focused on outer fabrics. However, there havebeen limited examples of such developments in the field of adhesive interlinings. Adhesive interlinings areused in various parts of clothing, making the development of sustainable interlinings crucial for composting
clothing and establishing a closed-loop system with PLA (polylactic acid).
Nittobo Advantex and Bioworks have been collaborating on the development of various biodegradable
garments since 2022, and have now developed a "biodegradable double dot" adhesive interlining using afabric made with "PlaX™" and an adhesive made with PLA.
"PlaX™" hydrolyzes under industrial composting conditions and eventually decomposes into water andcarbon dioxide. The realization of the "biodegradable double dot" adhesive interlining makes it possible tocompost clothing using adhesive interlining, which was difficult until now, and the fact that it is a double
dot interlining makes it possible to expand to a wide range of clothing. This is expected to contribute to therealization of a circular society as a pioneering step in promoting the closed-loop in the fashion industry.
Nittobo Advantex and Bioworks plan to develop a "biodegradable" adhesive interlining of filament in 2024.
We will continue to pursue further collaborative research and development, focusing on the creation ofsustainable auxiliary materials that take into consideration the environmental impact.
Comment from Yukihiro Imai, Representative Director of Bioworks
Bioworks aims to achieve a sustainable society through the development of materials that contribute toreducing environmental impact based on polylactic acid. This time, we have succeeded in developing abiodegradable adhesive interlining through joint development with Nittobo Advantex for our focused textile
applications. The adhesive interlining born from the joint development not only reduces the environmental

load compared to conventional products, but also adopts a versatile double dot interlining with excellent
adhesiveness, so it is expected to be used in more clothing. The development of "biodegradable" adhesiveinterlining will contribute to improving the recycling process in the fashion industry and help solve the waste
problem. Bioworks will continue to work towards the realization of a sustainable society through further
technological innovation and collaboration with partner companies.
About PlaX™
"PlaX™" is a novel carbon neutral material with improved quality and function, comprised of bioplastic
Polylactic Acid (PLA), a plant-derived material such as sugarcane, and additives exclusively developed byBioworks. It has attracted international attention as a new material which can, not only replace petroleumbased synthetic fibers such as polyester, but also be used to actively develop new applications.
《Features of PlaX™》
・Reduces CO2 emissions during yarn production by 41% compared to polyester.
・Has biodegradability that is decomposed into water and CO2 by microorganisms.
・ Research and development towards achieving a closed-loop system that circulates resources isprogressing, particularly in compatibility with chemical recycling, which involves reproducing equivalentmaterials from waste.
・Significantly reduces CO2 emissions during incineration disposal. It does not produce harmful substancessuch as dioxins.
