Resistance to abrasion of fifty kinds of woven fabrics were tested by U-M fabric abrasion tester, in dry and wet conditions applying respectively the same specimens in both conditions. Those specimens were made of various kinds of raw materials and also differed in texture, states of yarns used, strength, elasticity, thickness, density, etc.
It was found that the resistance to abrasion of the same fabric were generally lower in wet condition than in dry. And the reason of this result seemed mainly due to the facts that:
(1) Tensile strength, of the constituent fibers are generally weakend in wet condition.
(2) The frictional resistance to slippage of the fibers are also weakened by presence of water between them.
The relation between log (load value) and log (number of revolution of the abradant ring to the end point) were also linear simular to the relation previously reported on dry tests.
