The effect of weight reduction on static- and dynamic- drape coefficients of polyester-fiber fabrics was studied precisely using 2 sets of fabric samples, one of which had various weave densities of weft yarns. Following conclusions were obtained: (1) Node number; n, the revolving drape increase coefficient; Dr, and the dynamic drape coefficient at swinging motion; Dd, increase with the increase of weight reduction ratio, and saturate around the ratio of 23%. (2) Static drape coefficient; Ds, and the revolving drape coefficient at 200rpm; D200, decrease with the increase of ratio, however, the former also saturates around 20%. (3) The effect of yarn weave density at the same weight reduction appears clearly on Dd, D200, and Dr, and these drape parameters increase with the increase in yarn weave density.
