Objective hand measurement of materials used for disposable diapers

The objective hand measurement of the materials used for disposable diapers has been looked into, with consideration given to aspects of both dermatitis and comfort. The subjective hand of the commercially produced diapers both at the leg gatherings and at the center was assessed by mothers and female students. The mechanical and surface parameters of the diapers were measured with the KES‐FB system. The equations that connect the material properties to the subjective hand were obtained by using the stepwise block‐regression analysis method. It became clear that the hand of diapers could be predicted from the physical parameters, for which the calculated error was within the range of the standard deviation of the subjective hand value of each diaper. In a dry condition, it is expected that the hand of diapers could be satisfactorily evaluated by using only the surface and compression parameters.
