Principle of Martindale Abrasion Tester for Fabric Abrasion Test

Martindale Abrasion Tester is used to test the abrasion resistance of textiles, which is an important indicator of the quality of textile products and directly affects the durability and use effect of products. Specifically, it refers to the property of resistance to abrasion between fabrics or with other fabrics in the process of repeated friction.

The wear of textiles is reflected in the morphological changes of the fabric, which mainly include damage, loss of quality, discoloration of the appearance, pilling and other changes. There are many methods to test the abrasion resistance of textile products, such as surface grinding, curved grinding, hem grinding and compound grinding. The Martindale method is a kind of surface grinding method, which is widely used in the detection of wear resistance of clothing, home textiles, decorative fabrics and upholstery fabrics. The wear and tear of textile products is mainly reflected in thefollowing aspects: 1. During the friction process, the fibers continuously collide, and the fiber fragments in the yarn break due to fatigue damage, resulting in the yarn breaking.

2. The fiber is cut and broken, causing the yarn to break. 3. The surface of the fiber is worn, and the surface layer of the fiber is broken and lost. 4. Friction generates high temperatures, causing the fiber to melt or plastically deform, which affects the structure and mechanical properties of the fiber.

5. The fibers are pulled out of the fabric, loosening the yarn and structure of the fabric. The fibers can be completely pulled out with repeated handling, resulting in thinner yarns, thinner fabrics, and even disintegration.

My country\'s national standards are:

1, GB/T21196.3-2007 \"Determination of abrasion resistance of fabrics by the Martindale method for textiles, part 3: determination of mass loss\";
2. GB/T21196.4-2007 \"Determination of abrasion resistance of fabrics by the Martindale method for textiles, part 4: evaluation of appearance changes\".

3. GB/T21196.2-2007 \"Determination of abrasion resistance of textile Martindale fabric Part 2: Determination of sample breakage\";

The above is given The standard is the test method of abrasion resistance of fabric - Martindale Abrasion Tester. my country\'s national standard revision adopts the ISO standard, and the detection method is basically the same as the ISO standard, except that the scope of application of the standard adds coated substances, and for the detection of coated substances, the corresponding rules of damage to coating materials, friction load parameters, standard abrasives and standard replacement requirements for abrasives, etc.
