Investigating the effect of GSM and fabric thickness on the drape of denim fabrics.

Abstract

Drape is an important property, which affects the aesthetic appearance of fabrics used in garments. In this study, an investigation was under taken to find out whether there is an effect of varying GSM values (302, 366, 374, 381, 386, 430, 376, 435, 427, 321, 482 and 380) and fabric thickness on the drapability of denim fabrics. The study was conducted concentrating on denim jeans. The fabric samples were locally sourced. from the market and then cut out in sizes of 30cm diameter. The drapability was assessed using a control drape meter of the model YG8IID. Drapeability assessment has been done on the basis of changes in drape coefficient (DC), drape parameters, node parameters and structural parameters. Also, a method of expressing drape, node and structural parameters relating to the drape coefficient of fabrics has been developed. This method involves the area of polygon area. The results were analyzed in terms of correlation coefficients.
