A team of researchers investigated the potential of virtual prototyping by customizing a virtual fabric library based on measurements of textile mechanical property data from two knit and two woven fabrics. Optitex CAD software was used to create the virtual garment. Researchers referred to MSI data during fabric selection. Textile material characteristics such as weight, thickness, stretch, bend, shear, and coefficient of friction were measured in Optitex laboratory and were incorporated into the customized fabric library. Researchers customizing avatar features in Adobe Photoshop and Optitex 3D model properties. The virtual garments were then created by developing 3D virtual textile structures, applying texture mapping to virtual garments using Adobe Photoshop software, embedding into the Optitex CAD software fabric library. Concurrent with virtual garment construction, researchers constructed physical garment samples out of selected textile materials, comprised of one light and one heavy weight of both knit and woven substrates.
