How to Purchase a Qualified Martindale Wear Tester Advanced Reading:

The Martindale Wear Tester is used to measure the pilling of fabrics under light pressure. Under the specified load, the circular sample is rubbed with the abrasive material (ie standard fabric) with the planar motion of the trajectory forming the Lissajous figure. The sample holder containing the sample or abrasive is free to rotate about its axis perpendicular to the horizontal plane. Whether the sample holder is filled with the sample or the abrasive depends on the test method used. Its trajectory forms a plane frictional motion of a complete Lissajous figure, including 16-fold friction, i.e. the two outer driving wheels of the Martindale wear gauge rotates 16 times and the inner drive wheel rotates 15 times. The Lissajous figure prescribed in the standard is a figure formed by alternating movements. From a circle to a tapering ellipse until it becomes a straight line, from which the straight line widens asymptotically to a widening ellipse to the circle diagonally. The line repeats this movement. However, the instruments manufactured by many domestic small businesses without production qualifications and processing techniques do not have the standard Lissajous gauge at all, leading to uncertainties in the test results.

Remove the material from the grinding table, cover the surface of each grinding table with ordinary white paper with a diameter of (100±5) mm and a basis weight of at least 100 g/m2 and fix it on the grinding table imagine sure that the surface is perfectly flat.

Insert the stainless steel sleeve with the same diameter as the sample pin shank into the shank sleeve of the sample guide plate in turn, install an ordinary ballpoint pen and bring the pen tip into contact with the surface of paper. Rotate the instrument so that the number of rubs is 16 times to form a complete Lissajous figure.

Draw two parallel lines that just meet the extreme curves on opposite sides of the Lissajous figure. Draw two more parallel lines for the other two sides, making sure the lines intersect perpendicularly. Measure with an accuracy of ±0.2 mm on each side using an appropriate method. Check the 31 lines drawn, it is important to check the symmetry of the Lissajous figure. If the curves match or the spacing is uneven (see Figure A.1), turn designed according to the equipment suppliers, its appearance is beautiful and generous, it adopts a touch-sensitive screen, the interface is easy to understand, and it is easy to operate. The microcomputer system uses two counting methods, which are intuitive and easy to set. Test at the same time to improve test efficiency. The instrument is also equipped with two types of Lissajous (Lissajous) 24mm × 24mm, 60.5mm × 60.5mm movement track and various supporting accessories, which can be adapted to different test methods and standards.

This instrument is suitable for testing the degree of pilling of fabrics, such as GB/T4802.2, ASTM D4970, ISO12945-2, etc. The principle: Under specified pressure, the circular sample is filled with the fabric of the same material is rubbed according to the path of the Lissajous figure and the degree of pilling of the sample is evaluated after the specified number of revolutions has been reached. It's also for abrasion strength test of GB/T13775, ASTM D4966, ISO12947, and other fabrics. Its principle: under a certain pressure, the circular fabric sample will rub against the standard abrasive according to the movement trajectory of the Lissajous curve, causing damage to the sample, and the wear resistance of the fabric is expressed by the number of samples is damaged performance.
