A method to predict a diaper condition while worn is proposed in this study, based on the pattern paper of a disposable diaper, material properties and body shape. This paper in particular reports the analysis results on the posture of open legs when a tape-type baby diaper is worn by using the explicit finite element method. Upon analysis, geometric mapping of a diaper, dynamic computation regarding strain generated in a diaper resulting from mapping as a geometric boundary condition, and dynamic computation regarding strain of gather rubber as a geometric boundary condition are sequentially conducted to obtain the shape while worn. When the leg gather (hereinafter, “LG”) position as well as vacant space distribution was compared with the actual diaper in order to verify appropriateness of analysis results, the error rate was approximately 3.8% at maximum in regards to the LG position; therefore a certain level of appropriateness was confirmed. On the other hand, the error in analysis results was significant in the vacant space distribution, indicating the need to model the crease formed upon product packaging as observed in the actual diaper. Since it is possible to calculate the shape of a disposable diaper while worn based on the pattern paper and material properties with this method, it is considered to be useful upon investigating the shape of pattern paper in the design phase.
