| Résumé : |
This investigation is related to water vapor permeability and water absorption of natural and some synthetic uppers, shoe lining materials, and socks compared with the amount of sweat secretion of the foot. The physical characteristic values of the ahove mentioned materials for footwear are given in tables. The microclimate results of seven-hour wearing tests in a chamber are pigtured in several graphs. A discussion is given on why the relative humidities in these synthetic uppers and shoe linings reach unphysiological high values (more than 70 percent R.H.), whereas, on account of the high water vapor permeability of a box-calf or neat's leather, the humidity in shoes of these materials increases only for a short time during physical load. Even a very good sock is unable to store more than 15 percent by weight of sweat, and therefore it is incapable of improving the microclimate in shoes made of synthetics. The most decisive fact concerning comfort in footwear is the high water vapor permtability of all layers, while water and water vapor absorption are of secondary importance. Because of these facts, the overwhelming majority of synthetic footwear and man-made textile fibers must he improved. |
