How to test the pilling performance of fabrics
At present, the domestic laboratory and textile enterprises, fabric pilling performance test method is more often used is the random tumbling pilling test method, box pilling test method, Martindale pilling wear meter test method and round track pilling meter test method.
Random tumbling pilling test method：
Test instrument: random tumbling pilling tester.
In this test method, fabric specimens are tumbled in a cylindrical test chamber lined with cork and stirred with a stirring bar, and the specimens rub against each other and against the chamber walls. The motion of the fabric specimens is random and the processing time varies. The advantage of this method is that its random motion is very similar to the force situation of the fabric in the actual wearing process, but the fabric specimen will be stuck by the stirring bar during the test, so that the fabric treatment strength is not uniform in time, so the repeatability of the experimental results is poor. The test method is mainly used in DIN53867 and ASTM3512 standard.
Round track pilling meter test method.
Test instrument: round track pilling tester：
The test method, the first use of nylon brushes, under a certain pressure to circular motion track to make the fabric specimen pilling, and then use the standard fabric on the specimen for relative friction, so that the fabric specimen pilling. This test method is more widely used in China, can be used for chemical fiber fabrics, combed blended fabrics combed and rough combed wool fabrics, different fabrics with different standard pressure, pilling and pilling when the number of friction turns are not the same. The reference standard is IOS4802.1.
Box type pilling and pilling instrument test method：
Test instrument: box-type pilling and pilling tester
The test method, the fabric specimen set on the rubber tube, put into the wooden box lined with cork, the box in the axis of rotation to promote the specimen flip, the specimen and rubber tube and cork friction, so that the fabric specimen pilling and pilling. The test method in the fabric specimen movement is random, the repeatability of the test results is also better, but in the test process affect the fabric pilling more factors, such as the surface roughness of the cork and rubber tube, etc.. The test method is applicable to fabrics prone to pilling, such as woolen fabrics, reference standards are BS5811, IWSTM152, JISLIO76 and GB4802.3.
Martindale pilling test method：
Test apparatus: Martindale pilling and pilling tester
In this test method, the fabric specimen is mounted on a specific chuck and rubbed against the same fabric mounted on the abrasive table below under the specified pressure, causing the fabric to pile up and pilling. The movement path of the specimen is predetermined and its movement pattern is adapted from the Lissajous diagram. The test method simulates the formation of hair pilling by rubbing the fabric specimens against each other, and the set motion path and the specified pressure can ensure the high repeatability of the experimental results. The reference standards are IOS4802.2, 150 a 2945, ASTMD4966, etc.
