Martindale Abrasion Tester--An artifact that textile and leather enterprises cannot do without
The abrasion tester is mainly used to test textiles, outer layers of footwear, inners of shirts, bottoms of shirts and similar fabrics. It can do both dry rub and wet rub tests at the same time. Under a known pressure, the circular samples are perpendicular to each other. The Lissajous figure of the two simple harmonic motions is synthesized in a cyclic plane motion on a standard abrasive. Abrasion resistance is assessed as the specimen should not develop any holes within the specified number of cycles. The Martindale abrasion tester is widely used in textile and leather enterprises. The Martindale abrasion tester can be used for textile and leather abrasion tests and pilling experiments. At the same time, the Martindale abrasion tester It can also test the abrasion resistance properties of fabrics and leather under other conditions, so the Martindale abrasion testing machine in textile and leather enterprises is an artifact they cannot do without. The following are the parameters of Martindale Abrasion Tester: Meet the 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 Working principle: the fabric to be tested is installed above inside the sample holder and rub it against the abrasive mounted on the grinding table. The friction trajectory is a Lissajous figure. After the specified friction stage according to the test requirements, the fabric is removed and the abrasion resistance index is calculated or the level of pilling and pilling of the sample is assessed by visual description. Technical characteristics and technical parameters: 1. Number of stations: 9; 2. Counting range: 0-999999 times 3. Maximum stroke: horizontal 60.5±0.5mm, vertical 24±0.5mm4, the amount of pressurized material: Gripper: 200±1g, Clothing sample weight: 395±2g, furniture decoration sample weight: 594±2g, stainless steel disc: 260±1g. 5. The effective friction diameter of the grinding block: A type 200g (1.96N) friction head (9KPa) ￠28.8-0.084mmB type 155g (1.52N) friction head (12 KPa) ￠90-0.1mm6, the gripper is opposite to the grinding table Movement speed: 20-70r/min (adjustable) 7. Loading hammer quality: 2385±10g instrument configuration and consumables: 1. 9 sets of sample clamps 2, 9 KPa, 12 KPa weights, each 3, 38mm, ? 140mm sampler, each set of 4, 38mm, ? 140mm sampler pads, each 5, from A set of spherical test kits 6, a set of SM50 standard samples 7, a set of EMPA standard pilling samples, a set of SM-25 standard abrasive cloth 1.6m*5m 8, a set of standard foam 1.5m*0.5m (4 Blocks/sets) 9. One standard felt flannel piece of 10, 20 pieces of 90mm felt disc disc, 20 pieces of 11, 38mm, ?140mm sampler blades, 50 pieces each, 12 pieces, and other necessary accessories recommended by the manufacturer. Test steps of Martindale abrasion tester: 1. The sample is parked in the laboratory environment for more than 8 hours. 2. Cut a sample from the flat part of the sample. If it is an insole, it should be cut to the transfer part. 3. Remove the load and the load shaft from the testing machine. 4. Remove the top plate and test fixture. 5. Sample device: Loosen the fixing ring on the test fixture, take out the sample press, put the sample into the test fixture base, put a sample gasket between the sample and the test fixture base, and then Place the specimen press on the specimen spacer and secure with the retaining ring. 6. Installation of wool felt and friction cloth: Loosen the fixing screw and fixing ring, place the wool felt on the base and then spread the friction cloth, press a 2.5kg pressure plate in the middle of the friction cloth, replace the fixing ring and Tighten the set screw. 7. Reinstall the top plate, and pass the load shaft rod (12KPa) through the round hole on the top plate. 8. Place the test fixture with the sample face down on the base fixture, and adjust the circular groove of the test fixture to align with the load shaft, so that the load shaft is inserted 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. Matters needing attention: 1. The friction cloth cannot be used repeatedly, and a friction cloth needs to be replaced every time the test is completed. 2. The wool felt can be used repeatedly until the surface is worn or stained. 3. The insole should be clothed first, and then subjected to the Martindale abrasion test.
