A Study has been carried out on the hand properties of PET filament fabrics with highly twisted filling yarns in connection with such fabric construction parameters as fineness, twist level. fabric density and weave structure. From this study the following conclusions are made: 1. Bending rigidity is a major factor affecting the stiffness(Koshi). The anti-drape(Hari) and the flexibility with soft feeling(Shinayakasa) on the fabric. Bending rigidity also increases along with the fabric density. 2. Tensile energy is a major factor reducing Kishimi. The increase of the fabric density as well as the yarn twist level increases the tensile energy. 3. compressional energy is a major factor reducing Fukurami. Which is an important hand characteristics of New Synthetic Fabrics(Shingosen). The compression energy increases as the yarn twist level 4. Surface characteristic is a major factor for Shari. Geometrical roughness decreases as the fabric density increases and the yam twist level decreases.
