Fabric objective measurements for commercial 3D virtual garment simulation

Abstract

Purpose -The aim of this paper was to explore the use of objective fabric parameters in 3-D virtual garment simulation. Design Method -Two methods (FAST and Browzwear's fabric testing kit) of obtaining objective fabric measurements and the derived parameters for virtual garment simulation were studied. Three parameters (extension, shear and bend) were investigated to establish if the selected virtual software derived comparable parameters from the objective fabric measurements. Findings -It was found that the conversion from the objective fabric measurement data to the required parameters for virtual simulation varied significantly. Manual analysis of the objective measurements showed the two test methods to be comparable for extension and shear parameters; However, some adjustment to the test method was required. The third parameter to be investigated (bending rigidity) concluded that the test methods and results obtained from the two different apparatus were not comparable and recommended further experimentation using a different testing technique. Research limitations/implications -Future research should be conduct on a larger variety of fabrics ensuring comparable loads are used in the testing of the extensibility parameters. An expansion of this preliminary study should give more conclusive evidence of the trends observed. Originality -Objective measurement of extension, shear and bend properties were investigated in relation to the derived parameters for a selected virtual simulation package. An understanding of such parameters will aid the general industry in adapting 3D virtual garment simulation as part of the standard product development process, resulting in a significantly shorter product development cycle.

Objective analysis of the drape behaviour of virtual shirt, part 2: technical parameters and findings

“…One of the main reasons behind this is the nonavailability of a well-accepted protocol or guideline for fit analysis using such tools. It has been mentioned by several researchers (Kim, 2009;Kim & LaBat, 2013;Lim, 2009;Power, 2013;Power et al, 2011) that only visual analysis of virtual fit of clothing is solely not enough for use in the process of decision-making on the acceptance or rejection of virtual prototype, or altering pattern pieces to achieve desired fit in the virtual and ultimately in the physical prototypes. This research took an objective approach to analyse the drape behaviour of virtual shirts using three technical parameters.…”

“…Existing literature (Kim, 2009;Lim, 2009;Kim & LaBat, 2013;Power, 2013;Power, Apeagyei, & Jefferson, 2011) hinted that only a subjective approach is not sufficient to take a conclusive decision on the state of virtual fit of clothing. This demands an objective approach to drape analysis with a potential application in clothing industry.…”

Evaluation of the Accuracy and Practicability of Predicting Compression Garment Pressure Using Virtual Fit Technology

“…However, fabric properties can vary substantially even among the same fabric type. Hence, the input of objective fabric test results would be preferable but is not supported by most CAD programs due to proprietary, non-standardized commercial test kits (Power, 2013). Parametric models are avatars of varying age and gender that are built into clothing-specific CAD programs.…”

Comparing physical to virtual: fit and appearance of multi-layered cultural garments

“…16 Power et al 15 introduced methods of obtaining fabric mechanical and physical properties, such as FAST and KES-F. Moreover, Power 22 compared and interpreted the difference for six knitted fabrics. Moreover, there has been no systematic investigation on the validity of 3D clothing simulation for fit analysis, especially given the diversity of fabric properties.…”
