UV Protection of Cotton : the Influence of Weaving Structure

The consequence of diminishing the ozone layer is reaching the surface of earth by shorter but high energy UV-B rays and longer energy UV-A rays causing known skin aging and recently the formation of skin malignant neoplasm. Paper deals with the influence of different fabric construction on its ultraviolet skin protection expressed as ultraviolet protection factor (UPF). It is well known that clothing provides some protection against damaging by ultraviolet radiation but highly depends on fabric construction especially for longer pending in the sun. Fabric openness or porosity is a key parameter influencing ultraviolet (UV-R) transmission. Our work is focused on the effect of fabric density and cover factor using twelve woven fabrics from the same cotton fibres and yarn count but different in type of weaving and fabric density. UPF and UV-A and UV-B transmission were measured using transmission spectrophotometer Cary 50 Solarscreen (Varian) according AATCC Test Method 183-2000.
