Martindale Test
The Martindale test is a widely used method in the textile industry to assess the abrasion resistance and durability of fabrics. It measures the ability of a textile material to withstand repeated rubbing or friction, simulating the wear and tear that fabrics may experience during their lifetime. This test helps manufacturers and designers make informed decisions about the appropriate applications and potential lifespan of fabrics in various end uses.
The Martindale test derives its name from its inventor, Dr. Martindale, who developed the method in the late 19th century. Since then, it has become a standard test procedure for evaluating the abrasion resistance of textiles, including woven, knitted, and non-woven fabrics. The test is especially relevant for fabrics used in upholstery, drapery, apparel, and other applications where durability is crucial.
The Martindale test apparatus consists of a circular sample holder with a piece of abrasive material mounted on its surface. The fabric specimen to be tested is firmly clamped over a foam pad and placed underneath the sample holder. The sample holder is then rotated in a circular motion, causing the abrasive material to rub against the fabric repeatedly. The test is performed under controlled conditions, including the number of cycles, the applied pressure, and the speed of rotation.
During the test, the fabric undergoes a visual assessment at regular intervals to determine the point at which noticeable wear, such as pilling, fuzzing, or thread breakage, occurs. The number of cycles the fabric endures before such wear becomes apparent is known as the Martindale abrasion resistance or Martindale rating. The higher the Martindale rating, the more durable and resistant the fabric is to abrasion.
Fabrics with higher Martindale ratings are typically suitable for heavy-duty applications, such as upholstery in high-traffic areas or garments that undergo frequent use and laundering. On the other hand, fabrics with lower Martindale ratings are better suited for lighter use or decorative purposes where abrasion resistance is not a primary concern.
Several international standards organizations, such as the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM), have established specific guidelines and standards for performing the Martindale test. These standards ensure consistency and comparability of results across different testing laboratories and manufacturers.
In terms of top users and manufacturers of Martindale testing equipment, several renowned companies have established themselves in the field. Some prominent manufacturers include James Heal, SDL Atlas, and Testex. These companies specialize in producing advanced textile testing instruments, including Martindale testers, that comply with international standards and offer reliable and accurate results.
Additionally, various textile research institutes, universities, and quality control laboratories around the world utilize Martindale testing equipment as part of their testing protocols. These institutions use the test to evaluate fabrics, conduct research on new materials, and ensure the quality and performance of textiles in various applications.
In conclusion, the Martindale test is an essential method in the textile industry for assessing the abrasion resistance and durability of fabrics. It helps manufacturers, designers, and researchers make informed decisions about the suitability of fabrics for different applications. The test involves subjecting fabric samples to controlled rubbing under specific conditions, and the resulting Martindale rating indicates the fabric's resistance to wear. With its long-standing history and widespread use, the Martindale test continues to play a vital role in the development and evaluation of textiles.

Fabric is mounted flat and rubbed in a figure eight-like motion using a piece of worsted wool cloth as the abradant. The number of cycles endured before the fabric shows an objectionable change in appearance is counted and determines the fabric's abrasion rating.
