Universal Abrasion Resistance Tester G282
The instrument can be used to flat grinding, mill grinding, edge grinding, folding grinding and anti-frost, edge-close and fleece and other wear-resistant test, can be used for woven fabrics, knitted fabrics, coated fabrics, fleece fabrics, socks, knitted fabrics, knitted fabrics, felt, nonwoven, deep fabric, yarn, cord plastic film, rubber, leather, paper, and many other materials. The test sample may be dry or immersed in water, oil, or other liquids.
The instrument is mainly composed of control system and friction system. The sample is installed on the clamp and is tightened. The upper fixture with the sandpaper is going down, adjust the position of the weight so that the sandpaper in contact with sample surface, through the control system set the number of friction times of the sample, and start the instrument. The lower fixture base does front-to-back motion, so that the sample and sandpaper being rubbed against each other. When the number of times the movements reach the set value, the instrument stops and remove the sample to observe the degree of wear.
Suitable for testing all kinds of fabrics, including wear performance and wear resistance of clothing, shoes and industrial textiles.
Applications
The G282 Universal Abrasion Tester performs flat abrasion, curved abrasion, edge abrasion, folded edge abrasion, and resistance to frosting, pilling, and nap formation tests. Test specimens may be dry or immersed in water, oil, or other liquids. Suitable for woven fabrics, knitted fabrics, coated fabrics, pile fabrics, socks, felt, nonwovens, deep-pile fabrics, yarns, cords, plastic films, rubber, leather, paper, and various other materials.

Test Procedures
1. First, prepare the accessories and test samples.
2. Using the sample wrench, disassemble the fixture. Place the drum membrane and sample into the fixture, tighten, and secure the fixture.
3. Secure the abrasive to the upper fixture and attach the weights.
4. Turn on the instrument, enter the operation interface, set the number of cycles, and adjust the air pressure value.
5. As air pressure increases, the sample expands to a certain height. Lower the upper fixture to bring the abrasive into contact with the test specimen.
6. Press the start button to initiate continuous friction between the abrasive and the test specimen.
7. When the sample wears through, the test automatically stops. Turn off the instrument to end the test.
8. Remove the test specimen for analysis and comparison to evaluate the material's surface wear resistance.
FAQ
1.How do you test for abrasion resistance?
To test for abrasion resistance, the glove material is mounted and abraded by a spinning abrasive wheel until a hole in the sample material is present. The greater the number of cycles it takes to break down the sample material, the higher the abrasion resistance rating.
2. What is the working principle?
The sample is fixed under a specific tension while an abrasive medium (like sandpaper) is pressed against it with a controlled weight. The machine moves the sample back and forth, creating friction until a set number of cycles is reached or the material wears through.
3.Which two tests can be done to measure fabric abrasion resistance?
There are two standard tests for woven upholstery abrasion resistance, also known as the rub rate: Martindale and Wyzenbeek. Both involve testing equipment which simulate the natural wear of a seat cover, culminating in a number of 'rubs. ' The higher the number, the more resistant the material is to abrasion.
4.How do you test for abrasion on concrete surfaces?
Known as the BCA abrasion test machine, the floor surface is assessed by measuring the depth of wear created by three hardened wheels rotating over a circular (template marked) area for a standard number of revolutions (2850 + / – 10).
5.What is the unhealthiest fabric to wear?
The unhealthiest fabrics to wear are generally synthetics like polyester, nylon, acrylic, and spandex, along with treated materials (wrinkle-free, waterproof), due to their petrochemical origins, lack of breathability, chemical treatments (like PFCs, formaldehyde, carcinogens), and potential to trap sweat, causing irritation, rashes, or absorbing harmful chemicals through the skin. Semi-synthetics like conventional rayon and even non-organic bamboo also pose concerns due to their harsh processing chemicals.
