Abstract
The ultraviolet rays shielding properties of various kinds of fabrics were investigated and their results are as follows;
1) Aromatic polyester fibers and wool fibers have better shielding properties than other fibers.
2) Fabrics made of staple fibers are better than those made of filament yarns, and textured filament yarns are better than flat yarns.
3) Woven goods are better than knitted, and higher weight or higher density of fabrics are more capable of shielding from UV rays.
4) Darker or deeper colored fabrics are more able to absorb UV rays, and so have better properties.
