Outer-wear is the external layer which as responsible for than 90% from dealing with UV where falls on the perso. body. an important value in this paper is designed to investigate the clothes esisting efficiency against harmful UV radiation. So it to determine the more effective texture  structural  factors, in relation to the UV transmission properties of the light. Fiber content, Weave structure, clothing density, yarn density, fabric thickness, porosity and fabric weight were tested. PPMCC statistical method was used for analyzing the research results. Polyster blended with Nylon, woven with plain weaves showed inferior UV protection properties. Pure polyster fabrics woven with sateen structure have the best hygienic properties for resisting the transmittance of UV radiation either in short, medium or long regions (i.e. 200 – 400 nanometer).
