1. Instrument parameters: Martindale Abrasion Tester Scope of application: Martindale Abrasion Tester is suitable for woven fabrics, knitted fabrics, non-woven fabrics, decorative materials, coatings Abrasion resistance test of fabric etc. and test of apparent pilling performance.

The Martindale abrasion tester meets the following standards:
ASTM D4970 ISO 12945.2, GB/T 4802.2/13775/21196.1/21196.2 ASTM D4966 ISO 12947 FZ/T 20020 BS 3424-24/ 5690 ISO 12947.1/12947.2 M&S P17/P19/P19C NEXT 18/18a/18b ISO 5470-2 IWTO-40 JIS L1096 8.17.5 Method E Woolmark TM 112/196 BS EN 388/530/13770 ISO 20344
br/> Martindale Abrasion Tester Principle of operation:
The material to be tested is placed in the upper sample holder and rubbed against the abrasive installed on the grinding table. The friction trajectory is a Lissajous figure. After the specified friction phase according to the test requirements, remove the fabric and calculate the abrasion resistance index or evaluateu the fuzzing and pilling level of the sample through visual description.

Test Procedure Martindale Abrasion Tester:
1. The sample is parked in the laboratory environment for more than 8 hours. 2. Cut a piece from the flat part of the sample sample. If it is an insole, it must be cut to the transfer printing area.
3. Remove the load and load shaft from the test machine.
4. Remove the top plate and test fixture. 5. Sample device: Loosen the fixing ring on the test fixture, take out the sample compact, put the sample into the test fixture base, and put a piece of sample between the sample and the test fixture base gasket, then put the sample gland on the sample seal and fix it with a fixing ring.
6. Wool felt and rubbing cloth device: loosen the fixing screw and fixing ring, place the wool felt on the base and spread out the rubbing cloth, press a 2.5 kg pressure plate in the center of the rubbing cloth, install Return the locking ring and turn the adjustingstick tight.
7. Replace the top plate, insert the load shaft (12KPa) through the round hole on the top plate. 8. Place the test fixture with the sample facing down on the base fixture, adjust the circular groove of the test fixture to align with the load axis, and insert the load axle into the circular groove of the test fixture. 9. Set the number of times according to the standard, start the switch and start the test.
10. After reaching the set number of times, it will automatically stop and remove the sample to determine the result.

Notes on the operation of the Martindale Abrasion Tester:
1. The rubbing cloth cannot be used repeatedly and a rubbing cloth must be replaced each time a test is completed.
2. Wool felt can be used repeatedly until the surface is worn or stained.
3. The insole must first be dressed and then subjected to the Martindale abrasion test.
