Fabric Tester Martindale Abrasion Tester Experimental method
October 05 , 2020

Fabric Tester Martindale Abrasion Tester is suitable for two major test methods, the basic operation is as follows:

Method 1. The circular sample and the same material fabric are rubbed with the Lissajous figure motion trajectory under a given pressure. After reaching the specified number of revolutions, the grade of the sample is evaluated.

1.1 This test method is recommended for users to use the count-up in this instrument, which is more intuitive.

1.2 Prepare samples and abrasives according to standard methods.

1.3 The sample is clamped on the friction head required by the method standard, with the test surface facing outward. When the fabric tested is not greater than 500g/m2, a piece of polyester foam is placed between the sample and the friction head; when it is greater than 500g/m2 or a composite fabric, no foam is required. Nine samples received the same tension during clamping.

1.4 Place the felt and the abrasive on each of the nine sample tables. Place the sample loading hammer on the abrasive, and then tighten the abrasive ring to fix the abrasive ring on the sample table and achieve nine abrasives the same tension.

1.5 Put the friction head on the abrasive and insert the connecting rod through the station hole of the guide plate on the friction head. Whether to add a sample weight or disc, according to the requirements of each test method.

1.6 After confirming that the Lissajous motion curve specifications are correct, touch the start key and the instrument starts to work until the friction count reaches the set number of times and the instrument automatically stops.

1.7 Remove the samples, compare the standard photos in the rating box, and evaluate the pilling degree of each sample.

1.8 If the next test is connected, the reset button must be touched to return the instrument to its initial state.


Method 2. The circular fabric sample rubs against the standard abrasive under a certain pressure according to the trajectory of the Lissajous curve, resulting in damage to the sample. The number of wear-resistant times when the sample is damaged Wear resistance.

2.1 This test method is recommended for users to use the counting method in this instrument, which is more intuitive.

2.2 Prepare standard abrasives, standard bedding and samples according to standard methods.

2.3 Cover the standard abrasive with standard padding. The surface of the standard abrasive must not have wrinkles, knots or uneven thickness. And put a sample pressure hammer on the standard abrasive, and then tighten the abrasive ring to fix the abrasive ring on the sample table, and make nine abrasives under the same tension. A new standard abrasive or sample must be used at the beginning of each test, and the new standard abrasive must be replaced after the friction is over 50,000 times.

2.4 Place the sample on the friction head required by the method standard, and at the same time line the polyurethane foam between the sample and the friction head.

2.5 Put the friction head on the abrasive, and insert the connecting rod through the station hole of the guide plate on the friction head. Whether to add a sample weight or disc, according to the requirements of each test method.

2.6 After confirming that the Lissajous motion curve specifications are correct, touch the start key and the instrument starts to work, until the predetermined frictional rotation number, the instrument automatically stops.

2.7 Observe the degree of wear of each sample and estimate the number of revolutions of the friction interval required to continue the test. Then, according to the above setting method, re-set the friction interval revolutions in the setting display window and restart the instrument. If several of the nine samples have reached the end of the test, touch the corresponding station counting window, lock the station counting function, and remove the station friction head. Then continue the test until all nine tests are terminated.

2.8 Record the accumulated friction data of each station.

2.9 If the next test is received, the reset button must be touched to restore the instrument to the initial state, and then reset the predetermined friction rotation number.
