BREATHE FIBER

BREATHE FIBER

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

No stuffiness
Wool has intrinsic superior absorption and desorption properties, which help prevent stuffiness.
 
No odor
Wool has intrinsic odor-causing molecule absorption properties. BREATHE FIBER, which uses wool as its base material, does not lose any of its odor eliminating functionality no matter how many times it is washed.
 
Resists pilling
We have succeeded in making pilling, a common issue with wool product, less common through specialized processing. The material is also resistant to discoloration and fading.
 
Dry, smooth and comfort
The very unwool-like crisp feeling of the material provides a dry but smooth sensation when in contact with the skin.
 

Anti-TM Fiber

Anti-TM 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.
