                                                RESISTANCE TO SUNLIGHT

 

All POLISILK yarn is UV stabilized and therefore protected against oxidation and ultraviolet rays in sunlight. Only the best additives available in the market are used and regular trials are performed with the Suntest ultraviolet accelerator equipped with Xenon light.

The measuring unit for solar energy is 1 Langley which corresponds to:

 According to Landsberg, solar energy varies from a minimum of 60 kilo-Langley/cm2 in the Polar regions to 100-120 Kly/cm2 in the temperate regions, and to a maximum of 200 Kly/cm2 in the African dessert.

POLISILK yarn is protected so that after 1 year if exposure at 120 Klycm it maintains 70% of initial mechanical properties .

Our laboratory is equipped with ultraviolet acceleration equipment SUNTEX (Xenon light)
