Study on Drapability of Fabrics: — Analysis of the Mechanism of Drape Formation by Using a Flare-skirt Type Model —

Abstract

The mechanism of drape formation has been investigated by using a flare-skirt type model. This model is an applied example of the rubber ring model which is the most simplified model of an umbrella type. The testing conditions were that: the diameter of a supporting disc was 20cm and the hanging length of a skirt model was varied from 35cm to 90cm in five levels. The shape and the number of buckling wave (node) were observed. With decreasing the hanging length, the shape of wave becomes more clear and the number of nodes increases. Buckling wave of a thick material is more clear than that of a thin one. Comparing observed number of nodes with theoretical one, it is found that the equation to calculate the number of nodes can nearly be applied to this model. © 1979, The Japan Research Association for Textile End-Uses.
