The Pressure and Slide Friction on the Skin by Clothes.

本研究旨在探讨人体皮肤与织物在压力作用下的滑动摩擦现象。为此目的，制造模拟装置用于试验。该模拟装置能够在1500克压力下测量准皮肤与织物之间的摩擦强度。采用皮革与聚氨酯泡沫塑料相结合的材料作为仿皮。从压力载荷、滑动速度和含水率对摩擦强度的影响等方面讨论了滑动摩擦现象，并通过模拟装置的试验结果，明确了滑动摩擦的性质。随着压力载荷的增加，类皮肤与织物之间的摩擦强度增加。在这种情况下，摩擦强度受准皮肤的可压缩性质的影响很大。摩擦强度的增长率与织物的组织结构如组织结构和密度、织物的表面性质如粗糙度和摩擦力以及材料的含水量有关。在这种情况下，织物粗糙度的影响最大。该模拟装置的实验结果与实际人体皮肤效果的关系有待进一步研究。

The purpose of this research is to discuss the phenomenon of slide friction between body skin and fabric under pressure forces. For this purpose the simulated apparatus was manufactured for trial. The simulated apparatus is able to measured the frictional strength between quasiskin and fabric under the pressure force up to 1500 grammes. The material combined leather and polyurethane foam was used for the quasiskin. The phenomenon of slide friction was discussed from the following point, namely influences of pressure load, sliding speed and moisture content to the frictional strength.From the result of experiments used the simulated apparatus, the following properties became clear. The frictional strength between quasiskin and fabric increases with increasing pressure load. In this case the frictional strength is influenced considerably by the compressible property of quasiskin. The increasing ratio of frictional strength is related to fabric structures such as weave pattern and density, fabric surface properties such as roughness and friction, and moisture contents in materials. In this case the fabric roughness affects the most. Further study is necessary with regard to the relation between the experiment of this simulated apparatus and the effect of actual body skin.
