The most common responses to a questionnaire conducted by Okamoto Corporation which asked, “What concerns you when wearing shoes for a long period of time”, were “Stuffiness” and “Odor”. We have examined our products starting from the base sock materials and spent nearly 6 years time to develop our original “BREATHE FIBER ” improved natural wool in order to address these concerns.
Features of BREATHE FIBER
In the vast majority of the socks developed with antifungal processed materials up until now, the processing is applied to the just upper thread which is on the exterior surface of the sock. At Okamoto Corporation, we have instead focused on the under thread on the inside of the sock which comes into direct contact with skin, and developed our original “Anti-TM Fiber” (SEK Mark for Antifungal Finished Textile Products Certified) under thread which inhibits dermatophyte fungus development on fiber.
What is the SEK Mark for Antifungal Finished Textile Products?
The SEK Mark for Antifungal Finished Textile Products is a mark used to indicate certification by the Japan Textile Evaluation Technology Council. Testing is carried out using the ATP (Adenosine Triphosphate) luminescence measurement method which is a proven antibacterial testing method. The test subject fungi (2 types chosen from Aspergillus niger, Penicillium citrinum, Cladosporium cladosporioides and Trichophyton mentagrophytes) is incubated for 42 hours and then qualitative assessment is carried out of the growth state. Anti-TM Fiber has been certified in testing for Penicillium citrinum and Trichophyton mentagrophytes.
