Abrasion is manifested as a change in the shape of the textile, primarily in the form of breakage, loss of quality, and visual changes such as discoloration and pilling. When measuring the abrasion resistance of fabrics, three factors are generally considered: appearance change, sample breakage and mass loss.
Appearance change evaluation: Under a certain load, the sample in the fixture is rubbed against the abrasive according to the trajectory of the Lissajous curve plane movement, and the wear resistance of the fabric is determined by the appearance change of the sample before and after friction.
Test piece damage evaluation: Under a certain load, the test piece rubs against the abrasive material in the fixture according to the Lissajous curve plane trajectory. From the total amount of friction when worn, we can determine the abrasion resistance of the textile.
Determination of mass loss: Under a certain load, the sample in the fixture rubs against the abrasive along the Lissajous curve plane trajectory. Abrasion resistance is determined by the difference in mass before and after rubbing when the specimen is rubbed a specific number of times.
Among them, the first test method is more commonly used, because it provides intuitive data and convincing reference. Commonly used detection equipment often uses 5000 times as a cycle to calculate the number of wear cycles (in Martindale) that cause the material to wear to a certain degree. For example, the German National Textile Association specifies minimum requirements for various applications, the following are requirements for the abrasion resistance of mats.
In addition, we rate the abrasion resistance of the textile: the higher the score, the more durable the textile. The following scores are available online, but are not available in specific countries and regions of application. However, according to the points on the table, we can figure out the various uses of textiles.
