A Martindale Abrasion Tester, often simply referred to as a Martindale tester, is a widely used instrument in the textile industry for evaluating the abrasion resistance and durability of fabrics. It is a standardized and objective method for determining the suitability of fabrics for various applications, including upholstery, clothing, and other textile products.
The Martindale Abrasion Tester consists of a circular test specimen (usually a fabric sample), a rotating circular test pad, and a counterweight system. The key components and features of the Martindale Tester include:
1. Circular Test Specimen: This is the fabric sample that is being tested for its abrasion resistance. It is typically mounted on a circular frame and subjected to abrasion.
2. Rotating Test Pad: A circular test pad covered with abrasive material (usually emery cloth or sandpaper) is placed in contact with the test specimen. The pad is rotated in a circular motion, and the friction between the test pad and the fabric simulates the wear and tear fabrics might experience during their normal usage.
3. Counterweight System: The tester uses a counterweight system to apply a specific pressure on the test specimen. The amount of pressure can be adjusted according to the test standards and requirements.
4. Counter: The Martindale tester is equipped with a counter to keep track of the number of cycles completed during the test. A cycle refers to one full rotation of the test pad.
The test procedure involves subjecting the fabric sample to continuous rubbing against the rotating test pad. The test is typically conducted for a specific number of cycles. After a certain number of cycles, the fabric is inspected for signs of wear, such as pilling, abrasion, or holes. The test results can be used to determine the fabric's abrasion resistance and predict its durability in real-world applications.
