Experimental working method of tissue abrasion tester

Fabric Abrasion Tester, also known as Martindale Abrasion Tester, is mainly used for testing the abrasion resistance of textiles. It is an experimental item to be tested in many textiles. About the use and experimental operation of the Fabric Abrasion Tester The method is relatively simple, but you also need to pay attention to some matters, such as the control of the experimental time and other requirements, the engineers of Standard Group (Hong Kong) Co. , Ltd. will explain it to you.

It takes 10 days for the fabric abrasion tester to be used in textile test experiments, for example:

Test the treated specimen on the first day in a standard atmosphere with a temperature of 70 ± 2℉ (21 ± 1℃) and a corresponding humidity of 65 ± 2%. 
On the second day, place the test piece on Guanghua\'s rubber vibrating plate, and clamp the test piece in a suitable place without deformation. 
On the third day, under sufficient tension, place sandpaper or other abrasive material smoothly on the wear table. In this position, the pivot point is reached through a hole in the abrasive material. , the surface of the abrasive material is flat. If there is no specified material statement, the No. 0 abrasive material is sandpaper.
Note: If the carrier head is used that is always changed, it should be taken into account that the weight of the carrier head is measured by a calculator. During use, it becomes

The fourth day, the day vibrates. The force on the plate and the wear table determines the air pressure. In the absence of a specified material, the air pressure is 28 kPa (4 psi) and the force on the abrasive material is 454 grams (one pound). Make sure the air pressure regulator and expansion coupons are balanced with the loaded abrasive material before sanding begins. Get consistent board inflation, blahs to a higher air pressure, then decrease to test air pressure.

Day 5. If unidirectional wear is required, disconnect the rotating device from the test piece holder, and after the plate is inflated, rotate and adjust the fixture so that the test piece the required direction.

Day 6, where multi-directional wear is required or, if no wear direction is specified in the fabric specification, the rotating device attached to the sample holder.

Day 7. If during the test the fiber pieces cause significant vibration of the vibrating plate, remove the fiber pieces that prevent normal contact between the test piece and the abrasive material.

If irregular wear patterns are observed during the test on the eighth day, if the test piece slips in the fixture or if the air pressure is not constant, discard this individual determination and test another sample .

If the wet prtest piece is to be sanded on the ninth day, cover the dry test piece with 10 ml of distilled water at a temperature of 20 ± 2°C (70 ± 2°F).
