Gunze’s Technological Process

Gunze’s Core Technologies

  • Resin Processing Technologies

    Gunze’s resin processing technologies, including melt extrusion, film formation by a casting method, and melt spinning, have developed as the underlying technological base that supports our functional solutions business. We will continue to advance these core technologies so that they can help nurture new products and businesses.

  • Fiber Processing Technologies

    Gunze’s R&D in the area of fiber processing originates from its research on cocoon filaments, so its development is intricately entwined with the history of Gunze itself. After many years of study, Gunze’s advanced knitting and weaving technologies, fiber processing technologies, and comfort evaluation technology have developed into Gunze’s core strengths. These technologies are employed not only for apparel but for industrial materials and medical applications as well.

  • Surface Processing Technologies

    To meet the diversified needs of society, Gunze has sought ways to add more advanced functions to the processing of resins or fibers. As a result, Gunze has developed many new technologies, including thin-film formation, precision printing and dispersive mixing technologies. Gunze considers these surface processing technologies to be its key technologies, which enable further advancements in electrode formation and sensing. This will contribute to the development and societal adoption of IoT (Internet of Things).

    Comfortable wearable system for dairy cows

    Made using Gunze proprietary cool-touch material, this type of wear is designed to keep cows cool through vaporization of water-soaked material. This is combined with a water pouring system that uses conductive fibers as sensors to keep the quantity of water pouring at the optimum level. The wearable system helps protect dairy cows from stress caused by intense heat and minimizes drops in milk productivity. The system is a joint development with the Livestock Technology Department of the Kyoto Prefectural Agriculture, Forestry and Fisheries Technology Center.
