Whether out on the waves, on the beach, playing golf or on safari, people exposed to the sun need effective ultraviolet screening. Hence the masses of creaming and spraying that takes place every summer. And if that is still not sufficient, on go the textile “covers”, preferably combined with conventional UV protection. But what only a few people know is that cotton provides little resistance to UVA/UVB radiation, particularly when dyed light. Plus, if the fabric becomes wet, the conventional UV protection completely disappears. Enter Belfasun™ from Cognis – the world’s first sun-protective treatment for cotton featuring nano particles. Textiles subjected to this process can be relied upon to give safe and dependable sun protection. It ensures total UVB and 70% UVA radiation absorption, with the remaining 30% UVA being effectively scattered.
