Abstract:

This paper presents a study of the impact of body posture and the presence of functional and structural body changes on garment fit. 3D scanning on a sample of 50 male test subjects was performed. Body posture indicators were determined on 3D body models and a statistical analysis of the results obtained was performed. Test subjects from the sample were divided into three groups according to body posture types. Three body models with different body dimensions and different physiological spine curvature were selected and imported into a 2D/3D CAD system for computer-based garment simulation. 3D simulation of  a men’s jacket in the closest garment size was performed on selected body models. Garment fit was analysed on every simulated model and based on the analysis performed, garment pattern elements and measurements where it is necessary to enable modifications were determined. The most complex part of the research refers to the development of a parametric computer-based garment model which will be able to adjust according to anthropometric body measurements and body shapes with a different physiological spine curvature. Relationships between targeted body measurements and their impact on modifications of pattern segments were investigated as a starting point for defining mathematical expressions according to which values of measurement changes on  the garment pattern will be calculated. A parametric garment model pattern which enables adjustments according to different body sizes and body postures types was developed. Verification of the method developed was performed using computer-based 3D simulations on 3D body models with prominent problems of body posture.
