Measurement of Drape Appearance Similarity between Real and Digital Stretch Fabric

Abstract

This study aimed to visually compare the implementation of digital virtual fabrics for stretch fabrics mainly used in clothing that closely touch the body, using CLO. A digital fabric was used in CLO after measuring the weight, thickness, bending, and tensile force of five adhering clothing fabrics using a CLO fabric kit. The visual similarity of draftability was compared by measuring the area of the bending angle and the shape of the wrinkles of the real and digital fabric. A comparison of the bending angles showed that Fabric A was −0.75° and Fabric D was −2.5°, showing slightly lower drape properties than the real fabric. Meanwhile, Fabric B was 2.75°, Fabric C was 2.13°, and Fabric E was 1.375°, showing slightly higher drape properties in the vertical direction than the real fabric. Comparing the widths of the drape shapes, Fabric A was 0.77%, Fabric B was 1.27%, Fabric C was 0.06%, and Fabric E was 1.48%, which showed a slight difference. Fabric D showed a difference of 3.17% and was implemented where the digital fabric spread a little wider. As a result, the stretch fabric was visually expressed similarly to the real fabric as a whole in CLO. For 3D virtual clothing technology to be used widely in the close clothing industry in the future, more research on real clothing is needed.
