The impressions on the size, slack, slippage, comfort and fitness of panty hoses of four types, i. e., woolly, sheer, kennel and support types, were explored with three female subjects undergoing the wearing test reported in the preceding paper. The results were discussed in relation to the phenomena during wearing such as the slippage and change of area enlargement. The infuluence of their tensile properties on these phenomena was also studied. The small-sized and the middle-sized subjects perceive large slack at ankle or knee when wearing the sheer and kennel types. This may be related to the fact that knitted fabrics at ankle have higher tensile energy than those of the knee and the femoral regions. For the large-sized subject slippage was observed ready to occur. She reported the slippage at ankle or knee while she was wearing the sheer and support types, whose fabrics are stiff and lack in extensibility. The small-and middle-sized subjects tend to judge panty hoses of better fit to be more comfortable. The large-sized subjects' seemed to prefer the woolly type, tensile energy of which is rather small and uniform among different portions and there was no substantial correlation between the fitness and comfort for the large-sized subject.
The soil removal versus washing time curves were analyzed by the method of approximating to the kinetic equation in which a computer enabled an automatic change of the order. Polyester films and polyester mesh screens were used as flat substrate and clothes like substrate respectively, and palmitic acid was used as an oily soil model. Used parameters were the initial removal rate (DINIT) which correlates with the removal force of the system, and the recurrent order (Nc) which correlates with the decrease of the removal rate with the time elapsed. 1) In both cases of using soiled films and soiled mesh screens, Nc of the foam washing (parallel fixed type) was close to Nc of the immersion washing, and DINIT of the former was 3 to 5 times of the latter. 2) The foam washing (vertically fixed type) of the soiled mesh screen gave greater DINIT than that of the parallel fixed type and gave less Nc than that of the other types of washing. These results suggest that the action of bubbling sorption affects the function of carrying out of the soil from the inner portion of the substrate to the phase of wash liquid.
The authors examined the positions and amounts of the ease in patterns which affect the mobility of the pants. The test patterns were a sample with no-ease made from true development of real body surface of its lower part and six samples which differ in the ease. By using moiré topography, the authors examined the amount of clearance distances between body surface and each of seven worn samples of pants in stationary standing. The recovery of shape and the constriction of pants in motion were also examined in / after motions: 37 cm foot pace, 90°flexion at the hip and the right knee, 120°flexion at the hip. The results are as follows. 1) The amounts of the ease of pants in standing posture depends on its position where the ease is given. 2) The recovery of shape was marked in the sample with the ease at the buttock. 3) The constriction influence was rather small in the one with the ease at the linea scapularis than the other samples.
