Abrasion Resistance

Defining Abrasion resistance is the ability of a fabric to resist surface wear caused by flat rubbing contact with another fabric. There are two different methods commonly used to test abrasion, referred to as Wyzenbeek and Martindale, described in detail further below. Remember… Abrasion levels are often over specified in the faulty assumption that abrasion tests predict a product’s overall durability and life span. A recent industry survey indicated that for many end-use applications, factors other than surface abrasion are more likely to result in fabric failure and therefore should be considered when evaluating product durability. Considerations Before Specifying Abrasion resistance is only one component of durability. Considering this in combination with other factors will enable you to choose the most suitable fabrics for your project. • Always consult with your supplier to confirm that the fabric you are considering should perform well in the onsite environment. • Review the results of the other ACT recommended physical property tests for durability. Abrasion results alone do not predict a product’s lifespan. • Consider the style and quality of the furniture the specified fabric will be used on; seat pans with a waterfall edge and upholstered arms of a chair are common areas of wear. Is there adequate padding to support the upholstery? • Take into account the amount of traffic in the environment and the wear the fabric is likely to receive. Keep in mind, the ACT recommended physical tests for durability do not indicate how a product will perform in an abusive environment. • Determine whether or not the fabric will receive regular professional cleaning. Dirt is the enemy of fabric, but improper cleaning will also shorten the durability/lifespan of the product. • Evaluate whether or not the end use requires a fabric treatment. Applying treatments, finishes or backings to a fabric may enhance durability, but may also negatively affect flammability resistance, appearance or environmental properties. Abrasion Resistance: End-Use Examples It is up to the design professional to evaluate what is appropriate for a specific end-use. The following lists are suggestions and examples of end-use specifications based on ACT abrasion categories and are not intended to be comprehensive.
