| Abstract: | Somc ncw parameters of dynamic drapability, such as revolving drape increase coefficient (DJ, revolving drape
coefficicnt at 200 rpm (Dāāā), and dynamic drapc coeflicient at swinging motion (Dd), have been defined using a device of
dynamic drape tester and the regression equations are derivcd fi'om mechanical parameters of fabrics obtained Ii'om KES
systcm. These equations have been applied to polyester fabrics used for women's fine dress materials and the effects of
weave dcnsity, yarn twist and yarn count on these parameters studied. It is observed that Dr and Dd have a maximum value
at the optimum weave density. These values increase with the increase in yarn twist in the case of Dechine" fabrics. These
values decrease in the case of taffeta fabrics, and increase in the case of georgette with yam count. Changes in D200 with
weave density, yarn twist and yarn count are found to be little for all the fabrics. ode number decreases and conventional
static drape coefficient (Ds) increases with weave density. |
