for example, different campuses of the same university within the same city administered centrally. According to standard, we settle the number of times on the tester and turn on it. Won’t be stop itself until it achieves enough times in the measurement.

Test piece of fabric is placed in the specimen clamp, and it will be rubbed against with abradant in a Lissajous figure. According to the requirement, once the test piece is broken, test piece should be taken down to calculate its abrasion resistance index, or evaluate its ratingof pilling through the visual description of abrasion.

ENISO12947.4-1998 The abrasion and pilling resistance testing of fabrics by the Martindale method-part 4: measurement of appearance change. Equipped with two sets of grinding heads, Martindale Abrasion Tester TF210 can do pilling tests and abrasion resistance tests at the same time. Set a certain number of rubs as an inspection interval to observe the wear state of the specimen surface. The test ends when the sample is broken or when the specified number of rubs is reached. Abrasion resistance is how resistant a fabric is against other materials after experiencing constant friction. The abrasion resistance test achieves the agreed surface changes and the rub count is used as a measure of abrasion resistance. Design appropriate inspection intervals to observe changes in the appearance of the specimen, including discoloring, fuzzing, and pilling. The test protocol should specify the level of discoloring, fuzzing, and pilling on the surface of the specimen, and the test result is expressed in terms of the number of times the specimen rubs when it reaches a certain level of discoloring, fuzzing, and pilling.

Martindale PD690S Proving Unit Overview

Adopt servo motor control to improve the stability of machine operation and reduce machine noise. Choosing Martindale Abrasion Tester TF210 means choosing reliable rub testing results. Let the side of test clamp with test piece face down, and put it on the test clamp base. After that, the bearing axle should be adjusted until it aligns and inserts the circular groove of clamp. Select three corresponding total effective masses for the friction load according to the specimen use and fabric characteristics What’s more, we have upgraded the Martindale tester which is equipped with IoT technology, it is a new brand “ChiuVention”, The Martindale is a testing instrument that is used to assess the abrasion resistance and fabric pilling of textiles.

Both the Martindale and the Wyzenbeek tests have their advantages and disadvantages. In the UK, it is more common for manufacturers to use the Martindale test. This test is recognised as a standard method for measuring abrasion resistance in upholstery fabrics both in the UK and in Europe. That said, both types of tests are widely recognised and used. Some manufacturers and suppliers will use both tests to provide a more complete picture of a fabric’s abrasion resistance. In actual use, due to the different conditions of wear (e.g. force, size, abrasives, etc.), the structure of yarns and fabrics and the nature of the fibers are different, thus the mechanism of wear damage is different, with the following forms of damage.This method is applicable to textile fabrics with a low abrasion wear life. The selection of abrasives, the sampling method and the selection of the specimen fixture liner are consistent with the method for determining the breakdown of textile specimens and are not repeated here.
