New, unused fabric: Anti-virus "Clense" Oxford Red 117 cm x 52 cm This fabric uses the antibacterial and antiviral fiber processing technology "CLEANSE® / Clense®". It utilizes the fixed antibacterial component "Etak® / Etak" and is a unique processing technology developed by Kurabo that strongly fixes it to the fiber surface. It is said to reduce the number of specific viruses on the fibers by 99% or more and to inhibit the growth of specific bacteria. It is used in hospital bed sheets, white coats, food factory clothing, and children's clothing, and it has been confirmed that the effect lasts even after 50 home washes. It is recommended for everyday items such as masks, clothing, and handkerchiefs. *Please note that the antibacterial and antiviral processing is not intended to prevent or treat diseases. *Antiviral processing does not inhibit the function of viruses. *The evaluation of antibacterial and antiviral properties is based on the independent evaluation of Kurabo Industries Ltd. *The antibacterial and antiviral fiber processing technology "CLEANSE / Clense" is a registered trademark of Kurabo Industries Ltd.
