Protection from Solar Erythemal Ultraviolet Radiation – Simulated Wear and Laboratory Testing

Abstract

The effect of fabric type, color, fit and wetness on transmission of solar erythemal ultraviolet radiation through garments was investigated using laboratory testing and during simulated wear using a multivariate experimental design. The effect of fabric type, color, and wetness on UVB transmission (280–320 nm) through fabrics was determined under laboratory conditions using a spectrophotometer. Garments were also evaluated under conditions of simulated use in Queensland, Australia using polysulphone dosimeters. Dosimeters, placed against the ‘skin’ at selected sites on the torso and on the adjacent outer-surface of the covering garment, were used to measure solar UVB. During simulated wear the fabric type, fit and color were the main variables affecting UVB transmission through the garments. To optimize protection, dark fabrics with good cover should be constructed into garments with positive design ease, and be selected and worn as loosely-fitting styles that maximize the surface area covered
