How to Acquire a Qualified Martindale Wear Tester Extended Reading:

The Martindale Wear Tester Takes Getting 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 fullpermanent Lissajous figure, including 16-fold friction, that is, the two outer drive wheels of the Martindale wear tester rotate 16 times, and the inner drive wheel rotates 15 times. The Lissajous figure prescribed in the standard is a figure formed by alternating movements. This movement is repeated diagonally from a circle to a narrowing ellipse until it becomes a straight line, from which it progresses again to a widening ellipse to the circle. 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 Fsurface weight of at least 100 g/m2 and fix it on the sanding table Make sure 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 the 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 distance is uneven (see Figure A.1), consult the equipment supplier designed, 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, 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 rubbed according to the trajectory of the Lissajous figure and after reaching deThe degree of pilling of the sample is evaluated for the specified number of revolutions. It is also suitable for abrasion resistance 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.
