[principle]

According to J.G.Martindale design principles, and in line with the wool Industry Research Association specifications produced by a testing equipment. It uses the standard wool felt as a friction material, to rub the test items such as cloth, etc., of course, can be based on different test methods, different requirements, to change the friction material standard wool felt for other materials such as sandpaper to test leather wear Sexual or decolorization degree. The measured object is clamped on a cylinder and weighted by a standard weight (depending on the test method, pressing on the abrasive object, driven by vertical and horizontal eccentric wheels, to produce a Li Sha-Ru curve for the purpose of completing a multi- Friction test.For the general footwear material, when wearing friction effect test, mostly at the same time to dry, wet two methods to detect, to simulate the rain on the upper material, or sweat on the extent of the impact inside the shoe.


[Test procedure]

1. The sample is parked in a laboratory environment for more than 8 hours.

2. Cut a sample in the flat part of the specimen. In case of insoles, should be cut to the transfer site.

3. Remove the load and load shaft from the testing machine.

4. Remove the top plate and the test fixture.

5. Test device: loosen the test fixture on the fixed ring, out of the sample pressure, the sample into the test fixture base, in the sample and the test fixture between the base pad of a sample gasket, and then Place the test piece on the specimen pad and secure it with the retaining ring.

6. Felt and friction cloth of the device: Loosen the set screws and fixed ring, the sheep felt on the base and then covered with friction cloth, friction cloth on the pressure on the 2.5kg pressure plate, replace the fixed ring and Lock the fixing screw.

7. Replace the top plate and pass the load shaft (12KPa) through the round hole in the top plate.

8. Place the test fixture with the test specimen facing down on the base fixture, and align the test fixture circular groove with the load shaft so that the load shaft is inserted into the circular groove of the test fixture.

9. Press the standard set number of times to start the switch and start the test.

10. When the set number of times has been reached, the machine will stop automatically, and the sample judgment result will be removed.


[Characterization]

Martindale fabric abrasion resistance of the determination of the method of determination of sample damage, the determination of the quality of the loss of quality and appearance of three changes. Three methods are commonly used in the determination of specimen damage, the method error is small, clear and intuitive test results, the wear resistance of different fabrics easy to compare, in the clothing products, decorative fabrics commonly used. The quality loss measurement method and the appearance quality change method are more complex, but can reflect the abrasion state of the different friction stage samples. It has strong practicality in the production enterprises or scientific research institutions to analyze the use of the fabric. Wear resistance is an important indicator of the quality of textile products, a direct impact on product durability and use of results. Specifically refers to the fabric or with other substances in the process of repeated friction, resistance to wear characteristics.

Textile products wear mainly in the following aspects: First, the process of friction between the fibers continue to collision, the yarn fiber fragments due to fatigue damage fracture, leading to yarn breakage. Second, the fiber from the fabric out, resulting in loose yarn and fabric structure, repeated under the action of the fiber may be completely pulled out, resulting in thinning of the yarn, fabric thinning, or even disintegration. Third, the fiber is cut and broken, resulting in yarn breakage. Fourth, the fiber surface wear, fiber surface debris loss. Fifth, the friction produces high temperature, so that the fiber melt or plastic deformation, affecting the structure and mechanical properties of fiber. Wear performance in the fabric of the morphological changes are mainly damaged, the quality of the loss, the appearance of color, pilling and other changes.

Textile products, wear resistance testing a variety of methods, such as flat grinding method, song grinding method, hemming method and complex grinding method. Martindale method is a flat grinding method, is widely used in clothing, home textiles, decorative fabrics, furniture, fabric abrasion resistance testing.
