The Study on Ergonomic Factors of Protective Clothing Using 3D Body Scanning Techniques
Protective clothing systems protect the wearer from external hazards but, unfortunately, may cause significant negative influences on physical performance by additional energy cost of work 1. Protective clothing is known to impair work performance due to its added thermal insulation, reduced water vapour permeability, weight, bulkiness, stiffness, and possible friction between layers of clothes worn 1, 3, 4. In comparison with the well-established problems of heat stress associated with protective clothing, the influence from ergonomic aspects has not received enough investigation. In the few studies that have addressed the effects of clothing ergonomics on wearing comfort, measurements on bulkiness, stiffness and fit were taken manually 1, 2, 3. The disadvantages of manual measuring include high cost, low accuracy, and most importantly the physical contact changes the garment dimensions from initial untouched status. In this study a three-dimensional (3D) noncontact scanning technique is applied to determine the air gap sizes and distribution between clothing and human body. The relationships between air gap information and bulkiness, stiffness and fit are developed. Applying 3D body scanning technique in exploration of clothing ensemble, this method takes further the analysis of ergonomic factors to the full garment level.
