Test Report: Nanofiber Certification

Authentic Nanofiber NanoPoly’s nanofiber has an average diameter of 0.24 micrometers which was sampled, tested and analyzed by Taiwan Textile Research Institute (TTR) through scanning electronic microscopy and thus it is an authentic nanofiber. (*2016/3/30 The diameter of NanoPoly’s sampled and tested nanofiber is 0.24 micrometers)
