Gunze Limited has developed a next-generation antistatic sewing thread that uses neither carbon nor metal as its conductive material, applying proprietary resin processing technology from its plastic film business to combine high antistatic performance with a wide range of color options including white and vivid hues. The Osaka-based company, led by President Takahiro Oka and listed on the Tokyo Stock Exchange under code 3002, said the product overcomes a key limitation of conventional antistatic threads, which rely on carbon and are therefore limited to black or gray. Instead, the new thread uses ion-conductive polymers to dissipate static electricity, allowing it to be produced in pure white or dyed in a wide range of colors, including vibrant and multi-color variations. Gunze said its resin molding and processing technologies distribute the ion-conductive polymer optimally throughout the fibers, delivering superior antistatic performance and longer-lasting effectiveness than conventional products. The company is targeting applications in high-performance and fashion apparel, uniforms and workwear for precision machinery, medical, pharmaceutical and cleanroom environments, and interior and industrial materials such as carpets, curtains, automotive interiors and filters, and intends to expand its product range and actively promote the technology in B2B markets in Japan and abroad.
