    In order to evaluate formability of silhouette, drape coefficient obtained from circular specimen has been used.In this study, drape cofficient of lady's dress fabrics which are used mainly for one-piece dress or blouse is measured by FRL drape meter.And relationship between drapability and mechanical properties of fabrics is analyzed to correlate the drape coefficient with fabric mechanical property.
    Using mechanical parameters3√B/W, √2HB/W, 3√G/W and, √2HG/W which are derived from the analysis of bending of a cantilever of fabric having hystersis in bending and shear properties by applying the heavy elastica theory, the equation to described drape coefficient precisely is introduced.Where B, 2HB, W, G and 2 HG are bending rigidity, bending hysteresis, weight per unit area, shear stiffness and shear hysteresis respectively.
    As a result, it is shown that drape coefficient of lady's dress fabrics is very much influenced by√2HB/W and when the hysteresis in bending and shearing deformation of fabric is greater, the unstability in the drape shape becomes greater.Drape coefficient has high correlation with “HARI”and“SHINAYAKASA”and therefore, it is shown that drape coefficient is described also by primary hand values.

    The effects of some factors on the dimensional parameters of plain-weft knitted fabrics (kc=cl, kw=wl, kn=kc×kw, ks=kc/kw and t/l, where c and w are the courses/cm and wales/cm, l is the loop length in cm and t is the fabric thickness in cm) are investigated experimentally, using cotton paralleled yarns and plied yarns, and a nylon plied yarn.
    For the coarse nylon plain-weft knitted fabrics (K=7 .6-11.7), k-values are approximately constant, but t/l increases with the increase of the fabric tightness (K=√T/l, where T is the linear density in tex).
    The results obtained for the cotton plain-weft knitted fabrics (K=7.3-16.0) are as follows :
    (1) ks, kc and t/l increase with the increase of the fabric tightness (K).ks of plied yarns is dependent on the relaxation treatments (dry, wet, boil and wash), but ks of paralleled yarns is not.At any fabric tightness (K), kc and t/l after a wash-relaxation are always more than kc and t/l after a dry-relaxation, and t/l of paralleled yarns is always more than t/l of plied yarns for all relaxations.
    (2) For all yarns and relaxations, KW changes little over a range of K>11, but changes very large over a range of K≤11.
    (3) For all yarns after a dry-relaxation, Kn changes little over a range of K>10, but changes large over a range of K≤10.For paralleled yarns after a washrelaxation, kn increases with the decrease of the fabric tightness (K).
