SILICONE-BASED COMPOUNDS AND FWAS FOR UV PROTECTION

The Sun has a vital and powerful role in our everyday lives especially in summer. It promotes vitamin D, boosts morale and improves the sense of well-being, but it can cause skin damage such as sunburn, allergies, skin aging, and even skin cancer as well. The primary cause of skin cancer is believed to be a long exposure to solar ultraviolet (UV) radiation. It is, therefore, important to study various UV protective devices, one of which is a proper UV clothing. Textile fabric can reflect, absorb and scatter solar wavelengths, but in the most cases it does not provide full sun screening properties. For that reason, the future designers of UV protective materials should use both ultraviolet A and ultraviolet B filters to block totally solar UV radiation. The aim of this paper is to achieve UV protection of cotton applying silicone-based compounds and FWA's. Transmission spectrophotometer Cary 50 Solarscreen (Varian) was applied to measure UV protection according to AS/NZS 4399:1996. It has been seen that FWAs improves not only the fabric whiteness, but protection against UV radiation as well. Silicone based compounds (natural zeolites and silicones) addition to FWAs increase UV protection to maximum one. Moreover, silicone additionally improves the fabric.
