Moririn Co., Ltd. (Head Office: Ichinomiya City, Aichi Prefecture, President and CEO: Shunsuke Mori) has developed an innovative antibacterial processing technology specifically for polyester fibers, named "BioSISTM". This technology achieves overwhelming durability, meaning its effectiveness does not easily diminish even after repeated washing, providing a clean and comfortable environment for all scenes, including sports, medical applications, and daily life. ■ Background of Development In modern lifestyles, awareness of "odors" and "bacteria" in clothing is higher than ever. However, conventional antibacterial treatments have the challenge of their effectiveness fading with repeated washing. Moririn aims to protect wearers and bring peace of mind to those around them, and has developed "BioSISTM" as a "new standard of cleanliness" that maintains its performance over a long period. ■ 3 Features of "BioSISTM" 1. Overwhelming Wash Durability The biggest feature of BioSISTM is its remarkable durability. It maintains high antibacterial performance even after more than 50 washes. Furthermore, it boasts astonishing durability, with high antibacterial activity values demonstrated in 200 wash tests under severe conditions. Since the effect lasts for a long time with a single treatment, it reduces maintenance effort while keeping clothes in optimal condition at all times. 2. High Antibacterial Performance Tests were conducted by a third-party inspection organization on a wide range of bacteria, including "Staphylococcus aureus," which causes sweat odor; "Moraxella catarrhalis," which causes musty odors; "Trichophyton rubrum," which causes athlete's foot; and "MRSA," a concern in medical settings. In all tests, high antibacterial activity values significantly exceeding the passing criteria for the SEK mark textile product certification standard were demonstrated. 3. Active in Diverse Scenes Due to its high functionality, BioSISTM demonstrates its power in three main areas.
