This study compares the optical properties of 10 fabrics which are woven with circular shaped filaments and various types of non-circular polyester filaments. The effects of fiber cross-sectional shape on the optical characteristic of fabric were evaluated by subjective and objective measurements. According to result, when the light rays fall on a surface, the fabrics made of various triangular cross sectional filaments generally shows more luster than others. Subjective preference of fabric luster showed similar results as objective value. Not only fiber cross-sectional shape but also the filament configuration in the yarn comprising the fabric has influence on the reflected light of the fabrics.
