ISO12947 Martindale abrasion tester
1. Martindale method
At a given pressure ,circular fabric specimen and the same material, carrying out friction Lissajous trajectory graph, after achieved the required rotation, evaluate the pilling degree of the specimen. Also applies to “ISO12947 ” and other fabric wear test. The theory: circular fabric sample at a certain pressure, rubbing with the standard abrasive according to Lisa if (Lissajous) curve’strajectory, leading to specimen damaged, use the times of specimen damaged to represent fabric abrasion wear resistance.This method is suitable for all textile fabrics, but not for fabrics with a short wear life.
Reference:
ISO12947.2—1998 “Textiles – Determination of the abrasion resistance of fabrics by the Martindale method – Part 2: Determination of specimen damage”;
IS12947.3—1998 “Textiles – Determination of the abrasion resistance of fabrics by the Martindale method – Part 3: Determination of mass loss”;
ISO12947-4—1998 “Textiles – Determination of the abrasion resistance of fabrics by the Martindale method – Part 4: Evaluation of changes in appearance”.
2.1 Martindale abrasion resistance test Machine
The instrument learn the advantages of domestic and foreign similar equipment’s design, it with elegant appearance, and touch display screen, the interface easy to understand, easy to operate,computer system uses two counting methods, visual appearance, convenient setting, 8 station testing at the same time to improve test efficiency. Instrument also has two kinds of Li Sha Ru (Lissajous),saying 24mm × 24mm and 60.5mm × 60.5mm, and a variety of trajectory matching accessories, can adapt to a variety of test methods standard.
The Martindale method is a type of flat abrasion method and is widely used in the wear resistance testing of clothing, household textiles, decorative fabrics, and furniture fabrics. This method has small error, the test results are intuitive and clear, and the wear resistance of different fabrics is easy to compare.
