PDF The Establishment of Clothing Pressure Evaluation Method Using the Walking Soft Dummy

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.36 Vol.36

 Clothing pressure evaluation for product development and quality control is primarily performed by methods involving the use of hard dummies in a stationary state. However, such methods do not provide sufficient evaluations if it is assumed that people will be subject to a variety of dynamic effects while wearing the clothing. Therefore, in this study, we developed soft-waisted walking-type dummies to simulate the softness distribution of the human body and examined their potential use in a new method of clothing pressure evaluation.
 Two types of long girdles were used as specimens, and the clothing pressure measurements were taken at 11 locations on the waist and leg sections, using an air pack system. Static measurements were taken to examine the stationary upright condition with the legs held together as well as with the legs spread apart, while dynamic measurements were taken with the stride and speed varied in stages for examination.
 The trends in the measured values were approximately the same for the soft and hard dummies in the static measurements, although the levels of the measured values differed depending on the measurement locations. Differences in the measured values were observed between the stationary upright position with the legs spread apart and the stationary upright position with the legs held together in locations such as the groin and gluteal fold. The dynamic measurements also indicated that larger strides resulted in greater amplitude of the clothing pressure, and as the speed increased, a constant clothing pressure was applied, which reduced the fluctuation. The fact that time-series variation existed with movements, as described above, implies that it is necessary to change the stationary methods used for clothing pressure evaluation.
