Abstract
The purpose of this study was to estimate exactly the clothing pressure that is a factor of comfort requirement. Hitherto, pressure has been calculated by the following equation;where, P; pressure, T; tensile force, r; radius of curvature, h; horizontal direction and v; vertical direction. In this study, the propriety of this indirect method was examined by contrasting with the dome extention method. We devised the dome method that a cloth set on the equipment was expanded in dome shape by air pressure to produce the strain of the cloth in wear.The fundamental correspondence between the calculated method and the dome method was investigated. The pressures of girdle were measured by the both indirect methods and by a direct method using the semiconductor pressure sensor in the silicone oil bag. There were some discrepancies among the results obtained, and the possible reasons for these were discussed.The pressure exerted by model cloth that was woven with narrow rubber tapes, was measured by the dome method and compared with the value calculated from summation of tensile forces in rubber tapes.It has been shown that the dome method is more reliable than the direct method.
