21—THE MEASUREMENT OF FABRIC DRAPE

It is shown how the method of measuring fabric drape by supporting a circular specimen of fabric between smaller horizontal circular plates has been modified to allow a more sensitive test to be made on very stiff and very limp fabrics. The use of diverging light instead of parallel light is described, and the correction of the results for this change is calculated. A method of determining the drape coefficient by a paper-weighing method is also described.
