This standard uses Martindale abrasion meter to determine the abrasion resistance of textiles. This standard is applicable to all textiles, but for pile fabrics, when the height of the pile reaches 2mm, this method may be more difficult to test.
Other current abrasion test methods are: ASTM D3884, ASTM D3885 ASTM D3886, ASTM D4157, ASTM D4158, AATCC 93.
Principle of Abrasion Resistance Tester.
Abrasion resistance test means that under the condition of known pressure and abrasion mode, the specimen is abraded according to a geometric trajectory, the graph starts as a straight line, then becomes wider and wider and forms into an ellipse, then becomes narrower and finally forms a straight line again along the opposite direction of the original straight line. The specimen is repeatedly rubbed along the above trajectory up to a specified number of revolutions, and different methods are described to evaluate its resistance to abrasion.
This method is not generally considered very good in commerce, and the accuracy of this method in commercial comparative testing is poor due to the nature of the wear tester itself, where different test results are often obtained using the same tester, whether in internal or comparative testing with external. Although this method is not recommended for use as a commercial test, it is still widely used and considered preferable, especially outside the United States.
In business, once a dispute arises due to different test results, the buyer and seller should do some comparison tests to find out where the differences between the two laboratories lie. It may be better to use an authority to do the comparison. At the same time, the samples chosen by the two parties should ensure consistency, and it is a general practice for the two parties to use random sampling to find out the whole level situation. Once differences are found between the two parties, the unity should be corrected as soon as possible, otherwise the reasons for the difference in results must be explained to the other party.
The wear resistance test is greatly influenced by the conditions of the test, for example, the nature of the wear cloth, the difference in the action of the specimen on the wear cloth, the tension of the specimen, the pressure between the specimen and the wear cloth, and the change in the size of the specimen will all affect its wear resistance.
Since the results of this test are different due to the change of the wear cloth during the specified test, the wear cloth should be replaced periodically and checked periodically against the standard. The wear cloth should be used only once and should also be replaced when it reaches its service limit. If a hard metal or equivalent surface is used as a durable wear plate, it is not necessary to replace the wear plate accordingly in a series of tests. Due to the inconsistent use of the actual situation, the same wear plate may have inconsistent surface changes in the same period of time. Due to changes in the surface finish, changes in the durable wear plate may be caused, and due to the influence of other substances such as test samples, the durable wear plate needs to be cleaned periodically. The method of evaluation and the different evaluators will also affect the final abrasion test results.
The abrasion resistance of textiles measured by the instrument in the laboratory can be used as an indicator of the durability of textiles in practice.
Abrasion resistance is routinely evaluated on all types of fabrics, including woven fabrics, nonwovens, knitted garment fabrics, home textiles, industrial fabrics, carpets, etc. In this way there exist many different types of abrasion testers, abrasion resistant fabrics, test conditions, test procedures, methods of evaluating abrasion resistance and interpretation of results, etc.
