This paper is on the luster property of textile fabric materials which is one of the important factors related to the development of clothing materials leading to the value-added products. Using several image analysis techniques, the optical properties, especially luster related ones, of the commercially available fabrics were measured and analyzed. The fabric samples included 6 lands of preliminary experimental fabrics along with 22 lands of fabric which were commercially available. The images acquired at various observing angles are taken by 44 points and these pictures are analyzed into luster through the image analysis program. The preliminary experiment demonstrated the effect of weave types and the number of yam twist on the luster of the fabrics through the use of the image analysis program.
