A Quantitative Fabric Drape Evaluation System Using Image-Processing Technology, Part 2: Effect of Fabric Properties on Drape Parameters
A new quantitative fabric drape evaluation method using image-processing technology was published in Part 1 and submitted to the International Organization for Standardization as a revised international standard. In this research, the effects of fabric properties on drape parameters have been examined using the new drape evaluation system to verify the new method. Drape parameters include the number of drape nodes, the amplitude of the drape wave, and drape wavelength, as well as drape ratio (coefficient). The Kawabata Evaluation System (KES) was used to measure the mechanical properties of 60 woven fabric samples. Through correlation analysis, we found that tensile, bending, and shear properties of fabrics are closely related to each drape parameter. Some regression equations were derived to predict the drape ratio, the number of drape nodes, and the wave amplitude from the KES fabric properties. In all regression models, the bending hysteresis (2HB) of a fabric and its combined value with fabric weight (2HB/W) were observed to be the most significant factors.
