【摘要】: The resistance to abrasion of textile materials is affected by many factors in a complex manner. The results obtained from the use of this instrument assist in evaluating these factors relative to the wear serviceability of the final textile product in specific end uses. The resistance to abrasion is affected by many factors that include the inherent mechanical properties of the fibers; the dimensions of the fibers; the structure of the yarns; the construction of the fabrics; the type, kind, amount of treatment added to the fibers, yarns or fabric; the nature of the abradant; the tension on the specimen; the pressure between the specimen and the abradant; and the dimensional changes in the specimen. Experience has shown in many instances, that relative results obtained with this instrument when used on a series of fabrics, agreed with those obtained based upon performance in end use. However, caution is advised because anomalous results may occur due to uncontrolled factors in manufacturing or other processes. Specific instances have been described. , , , In any event, anomalous results should be studied to further understand the complex behavior that may occur as a result of abrasion that may in turn assist in the development of more durable fabrics. Testing some specimens under x201C;wetx201D; conditions can add another dimension to the evaluation of some textiles. Such testing under x201C;wetx201D; conditions can help ascertain the effect of changes in a fabric''s resistance to abrasion when it becomes wet. This test can also increase the uniformity of the abrading action by washing away abrasion debris and preventing the build up of broken fibers that can interfere with the proper progression of the tests. This test is used as a guide in evaluating textiles in quality control and in research. If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples should be used that are as homogenous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other fabrics with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either a cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. This test is unique and is significantly different from any other existing abrading test. This guide may also be used as a technique for pretreating material for subsequent testing. For example, a predetermined number of abrasion cycles at specified test conditions may be performed on a series of specimens, which are then subjected to a strength or barrier performance test. The resistance of textile materials to abrasion as measured by this guide does not include all the factors which account for wear performance or durability in actual use. While the x201C;abrasion resistancex201D; stated in terms of the number of cycles and x201C;durabilityx201D; (defined as the ability to withstand deterioration or wearing out in use, including the effects of abrasion) are frequently related. The relationship varies with different end uses, and different factors may be necessary i......
