Martindale Abrasion Tester Leather Abrasion Test Method

Author: Released in:2023-03-17 Click:16

The Martindale Abrasion Tester, also known as Martindale Abrasion Tester, is widely used in the textile and leather industry, mainly for the friction resistance of the user\'s textile or leather. The friction resistance here is divided into dry friction and wet friction. are two types of friction, and the basic methods of testing these two types of methods are different because the test conditions have changed. The engineer of Standard Group (Hong Kong) Co., Ltd. will explain to you the Martindale Abrasion Tester experimental method of wet friction.

Standard Consumables for Martindale Abrasion Tester: Wool Felt (140mm, 90mm), Wool Fabric (140mm), Foam Pad (38mm)

1. Test Sample The cutting device, such as a press knife, is large enough to produce test pieces that can be pressed firmly against the test piece carrier. The exact dimensions of the test piece are determined by the clamps of the test piece carrier. Voor in case the SATRA STM105 would have a round diameter of 44+ - 1 mm. An additional test sample was cut from each position of the plate 50mm from a fabrication edge for comparison or reference to sample discoloration or wear.
2. Place the test sample in an environment of 20+/-2°C and humidity 65+/-2% for 24 hours.
3. Steps Moisten half of the abrasion resistant samples and half of the wool felt until the color of both sides of the sample is noticeably darker. Place the sample in each clamping ring with the test side facing out.
4. If the quality of the test sample reaches 500g/m2, test method A or B can be used to put foam in each sample container to fill the test space of the sample.
5. Clamp the sample to prevent the test sample from hanging, wrinkling and deformation. 6. Place a piece of dry wool felt on half of the wear samples. Place a dry wear sample on topt wool felt with the test side up.
Place the weight on the sample, smooth out the wrinkles, remove the weight and place it on another sample and repeat the wool felt steps. 7. Correctly place the test sample in the test fixture to ensure that the test can be performed normally. Load the force on each test head to ensure that the test sample and the wear-resistant sample are loaded according to the required force value. Martindale Abrasion Tester Textile Testing: 8. Textile and Leather Abrasion Test The round fabric sample is rubbed against the standard rubbing cloth. The wear resistance depends on the number of rubs or the weight consumption of the sample when the sample is decomposed. The oscillating trajectory on the sample rubbing cloth is called Lissajous figure.
9. Pilling test on textiles and fabric The pilling test method applied to the Martin-Dell test machine was developed in collaboration with EMPA. The test is suitable for both knittingthe as-woven fabrics (sand-woven from staple fibres). The standard described in language is combined with the EMPA image standard to evaluate the degree of pilling.
10. Movement and amplitude Some activities require regular interactive movement testing according to the Lissajous chart. From wear testing to fluff Testing the ball requires changing the length of the amplitude. Changing the operating mode and amplitude is very easy, just move the position of the drive unit, without the need for other tools and spare parts.
