CLO3D Simulation versus Real Drape Test for Assessment of Garment Drape Coefficient

Abstract

owadays, the era of virtual fashion and simulation is of prime importance in clothing technology. Virtual fashion necessitates the accuracy of the virtual garment product. On the contrary, the physical sampling trials are time and material-consuming. Herein, we suggest a method for the fashion designer to visualize the drape coefficient value of the fabric using virtual garment products, to help the designer produce an identical virtual piece of the actual product. This method is based on the fabric drape coefficient test, as the drape coefficient reflects all fabric characteristics. In this work, several trials were conducted virtually to measure the validity of the capability test, and to correlate it with a virtual standard. Three different fabrics, cotton, polyester, and cotton polyester blend (50/50), were used in this study. The physical parameters were investigated following the CLO3D software standard method.The assessment of the final form of garment appearance must be referred to as values to avoid the conflict of human judgment. Therefore, the drape coefficient of fabrics was measured (using shadow analysis), in both real and virtual phases, and the relationship between them was assigned. Four types of flared skirts were used to assemble the fabrics based on the angle of construction, and three skirt lengths were used virtually. The skirts were simulated using CLO3D software and the skirt's hemline formation shape was analyzed, to find the most descriptive flared skirt to the drape coefficient value.
