Several psychological and/or physical evaluation methods for fabric drape have been studied. Among them, Hamburger's method has a great advantage of simple measuring procedures. Hamburger's drape coefficient, however, has few information on the image of the fabrics drape. Various shape factors proposed until now, were too closely related to the drape coefficient.
In this paper, the following parameter was found a good measure for evaluating the shape of the fabric drape.
α
2parameter=Σ (X
i-a)
2/N⋅a
where X
iis the angle of the i th node measured on the circle of the projection whose area equals to that of the projection, a is the angle of the node if all of them were equal, and N is the number of the nodes of the projection.
The results suggest that the drape including both drapability and the shape should be evaluated using at least two parameters. A set of Hamburger's drape coefficient and α
2parameter can be useful for the drape evaluation.
