Nanoyarn is developed by our FINEYARN CORPORATION with Shanghai Communications University. Its main raw material is a new kind of UV- resistant chips made through nanotechnology. The fabrics, made with Nanoyarn, feature permanent UV-resistant, and can be used in curtains, umbrellas, caps, sports wear and casual wear.
Ultraviolet Protection Factor: 68
UV-A Transmittance Ratio: 8.28
UV-B Transmittance Ratio: 0.77
The Blocking Percent, UV-A: 91.72
The Blocking Percent, UV-B: 99.23
Ultraviolet Protection Factor(UPF) is the ratio of the average on effective ultraviolet radiation(UV-R) irradiance transmitted and calculated through air to that on fabrics.
The limits of the spectral range of ultraviolet radiation are not well defined and may vary according to the user. Committee E-2, 1, 2 of the international Commission on illumination(CIE) distinguishes in the spectral range between 400 and 100 nm:
