Frequently Asked Questions | FAQs
How is fabric abrasion measured?
Fabric abrasion resistance is a measure of a textile material’s ability to resist damage or wear caused by friction. There are several standardized methods for measuring fabric abrasion resistance, including the Martindale abrasion test and the Wyzenbeek abrasion test.
The Martindale abrasion test is a widely used method for evaluating the abrasion resistance of fabrics. It involves rubbing a sample of the fabric against a standard abrasive material in a circular motion, using a specified pressure and number of cycles. The fabric sample is then examined for signs of wear or damage, such as pilling or visible holes. The test is repeated with increasing numbers of cycles until the fabric reaches a defined endpoint, such as a significant change in appearance or failure of the fabric.
The Wyzenbeek abrasion test is another common method for measuring fabric abrasion resistance. It involves rubbing a piece of cotton duck fabric back and forth against the test fabric, using a specified force and number of cycles. The test is repeated until the test fabric shows signs of wear or reaches a defined endpoint.
Both the Martindale and Wyzenbeek tests produce a score or rating that indicates the level of abrasion resistance of the fabric. Higher scores indicate greater abrasion resistance, and fabrics with high scores are often used in applications where durability and long-lasting performance are important, such as upholstery, workwear, or outdoor gear.
How do you increase abrasion resistance in fabric?
There are several ways to increase the abrasion resistance of a fabric:
Choose the right fiber: The fiber used to make the fabric plays a significant role in its abrasion resistance. Fabrics made from natural fibers like cotton or silk have lower abrasion resistance compared to synthetic fibers like nylon or polyester. Therefore, choosing fabrics with synthetic fibers can increase their abrasion resistance.
Increase the fabric density: The density of a fabric is a measure of how tightly woven the fibers are. Increasing the fabric density by using a higher thread count or tighter weave can improve the fabric’s abrasion resistance.
Use durable finishing techniques: Certain finishing techniques like calendaring or resin treatments can help improve the abrasion resistance of a fabric.
Incorporate abrasion-resistant fibers: Some fabrics are made by combining different fibers to create a blend that has improved properties. Incorporating abrasion-resistant fibers like Kevlar or Cordura can increase the fabric’s abrasion resistance.
Apply coatings or laminates: Coatings or laminates like PU (polyurethane) or TPU (thermoplastic polyurethane) can be applied to the fabric to increase its abrasion resistance.
Overall, it’s important to choose the right fabric for the intended use, considering factors like fiber type, density, and finishing techniques to ensure that it has the required abrasion resistance.
