Introducing the world’s first sun-protective cotton treatment based on nanotechnology. Belfasun™ contains tiny particles of nano zinc oxide, bonded to the fabric’s fibers, which serve to absorb or scatter UVA and UVB radiation. UVB rays are completely absorbed and UVA rays are 70% absorbed with the rest being scattered. The nano particles are invisible to the human eye – hence the colors of the textiles remain clear and brilliant. In contrast to the more conventional UV filters, Belfasun™ is toxicologically harmless and offers a generally very high tolerability level. There are no known allergies triggered by zinc oxide. Even if the fabric should become wet, for example due to rain, perspiration or (sea-) water, the sun-protective effect remains intact. This is not usually the case with traditionally finished textiles. And best of all: Belfasun™ can withstand even frequent washing – the sun-protective effect will survive at least 40 washes at moderate machine settings.

Aside from sport and apparel textiles, the Belfasun™ UV-protective treatment is also ideally suited to all cotton fabrics used as utility textiles - such as parasols, marquees and awnings. While a parasol of lightly dyed cotton provides pleasant shade, it hardly protects at all from UV radiation. For small children and light-skinned people, an additional UV-protective treatment of the fibers is therefore a must.
