An investigation has been made of difference of swinging properties of skirts on the dammy attached with legs and without ones.

  Rotational vibration at the angle of 60° were given on the dammy weared a skirt at 120pps (54times/min.) of walking speed. The motion hemline of 14 types of flared skirts were catched by the camera and X-Y tracker, and drawed the locus by the X-Y recorder.

  The results obtained are as follows :

  1. Significant relations are given between the swinging length, swinging width and swinging area of the short sized skirs of hemline on the dammy attached with legs and without ones.

  2. At the long sized skirts of hemline, significant relations is recognized between the swinging length with legs and without ones. No relations are given however between the swinging width and area with legs and without ones. Then, the influence of the motion of legs can not be neglected to the swinging properties.

  3. At the short sized skirts of hemline. Significant relations are given between the swinging width and area and shear rigidity G. Then, they become largely in the small order of shear rigidity G of fabrics.
