Martindale pilling tester video operation method

The Martindale Pilling Tester can test the abrasion resistance and pilling performance of different plants. Under a certain pressure, the sample and the specified abrasive are subjected to continuous reversing friction, and the degree of wear and pilling is evaluated by comparison with the standard parameters. Touch screen operation with complete programmer, pre-programmed batch and total counts, individually set counts for each test head; 4 speeds selectable including standard speeds.

Operating Principle:
1. Under a certain pressure, the circular sample and the fabric of the same material are rubbed according to the movement trajectory of the Lissajous figure to reach the specified number of revolutions. Then evaluate the pilling level of the sample. This principle corresponds to the test of the degree of fluffing and fluffing of fabrics as determined in the standard 2. Under a certain pressure, the round fabric sample and hThe standard abrasive against each other according to the trajectory of the Lissajous curve, resulting in When the sample is damaged, the abrasion resistance of the fabric is expressed by the number of times the sample is damaged.

Test Principle:
1) Friction Resistance Test
The round fabric sample is fixed on the sanding table, and the friction test is performed with the friction head fixed with the standard friction cloth.
There are three evaluation methods: the determination of sample damage, the measurement of mass loss and the evaluation of appearance changes
2) Pilling test
The pilling test method used on Martindale is combined with EMPA developed. The test is suitable for knitted and woven fabrics (made from spun yarns). Use a test instrument to simulate the pilling that occurs during normal wear and tear. Using light pressure, rub the sample on the sample holder and the fabric on the grinding table with a certain geometryric figure and then grind the sample compared to standard photographs. According to the types of samples tested, it can be easily divided into: sample photo knitting pilling review, sample photo woven fabric pilling review. And it is divided into five degrees according to the redness of the eyes of pilling
5-no pilling? 4-light pilling? 3-moderate pilling 2-severe pilling 1-very severe pilling

Test method:
The test sample is rubbed against the standard friction cloth under the specified pressure and after reaching the predetermined number of revolutions the abrasion resistance of the sample is evaluated.

Notes on how the Martindale Pilling Tester works:
1 .The rubbing cloth can not be used repeatedly, and a rubbing cloth must be replaced each time a test is completed;
2.The wool felt can be used repeatedly, if the surface is worn or stained, it must be replaced, and the be used on both sides;
3.The insole should be dressed first, then Martindale wear test should be done;
4.After the test is completed, if the surface of the surface table is abnormal, the sample will exhibiting signs such as abrasion, broken yarn, pilling, severe pilling and severe abrasion will be judged as unqualified.
5. When making samples, pay special attention to the cutting edge to avoid hair changes. Unwanted loss of mass and change in appearance .
