The Martindale tester is an important instrument in textile testing used for both pilling and abrasion resistance tests. These tests simulate the real-world frictional wear and surface pilling. Improper switching between abrasion testing ISO 12947-2 to pilling testing 12945-2 can lead to inaccurate results, sample waste, and delay in production. This article guides you on: Pilling vs Abrasion: How to Switch Your Martindale Tester Configuration Correctly.
Martindale tester for both pilling and abrasion testsUnderstanding the Martindale Tester: Key Concepts
The Martindale tester applies the same real-world mechanical stress on the testing specimen undergoes during everyday use. This tester assesses abrasion resistance and pilling resistance, both are essential qualities that determine how a fabric will hold up over time.
Abrasion Testing
With the help of abrasion testing, we can evaluate the ability of a fabric to withstand wear caused by friction. In practice, the fabric is subjected to rubbing under controlled conditions, such as temperature, humidity, and pressure, as per the standard, simulating the effect of fabrics rubbing against other materials such as clothing or furniture. This test is very important for fabrics that will undergo heavy usage, such as outdoor clothing, upholstery, and industrial fabrics.

When fibers on the surface of a fabric become tangled and form small balls called pills. These pills affect the overall appearance of the fabric and its aesthetic appeal. The Martindale tester replicates the friction that causes these pills to form, helping a lot of manufacturers and quality researchers to assess how easily their fabric will develop pilling over time. Pilling is very important for textile materials used in apparel and home furnishing, where texture and appearance matter a lot to consumers.

The Main Differences in Test Configurations: Pilling vs Abrasion
To get reliable and reproducible testing results, it’s important to understand the key differences between abrasion and pilling testing. The Martindale tester should be configured to different settings as instructed by ISO 12945-2 and ISO 12947. These differences are explained below:
Stroke Length
The stroke length of the abrasion test (ISO 12947-2) is longer to simulate continuous wear. Usually, the stroke length is set to 60mm, which represents the repeated friction that a fabric would undergo over an extended period of time.
The stroke length of the pilling test (ISO12945-2) is shorter, and around 15mm, which simulates localized friction that causes the entanglement and pill formation. This shorter stroke length helps replicate the exact conditions that lead to the development of pilling.
Test Duration
The duration of the abrasion test is longer. The testing specimen was subjected to repeated rubbing over a prolonged period.
The duration of the pilling test is shorter, as this test focuses on evaluating the early stage of pilling formation.
Abrasive surface
In an abrasion test, the testing specimen is rubbed against a coarse abrasive surface. This is very important to simulate the physical wear caused by contact with a rough surface.
In the pilling test, the testing specimen is rubbed against a soft surface, usually wool or cloth. This shows the same as the rubbing that causes fiber entanglement, which leads to pilling
Step-by-step workflow for Switching Martindale Test Configurations
Careful attention is required while switching the test setup between abrasion testing and pilling testing. To ensure that the tester is configured properly every time, always follow the right workflow. Below are the points to switch the configuration accurately.
Prepare Testing Specimen
The sample must be cut according to the required dimensions, and any contamination that could affect the results. The sample must be free of wrinkles.
Set the Stroke Length
For the abrasion set the stroke length to 60 mm to simulate the long-term friction, and for the pilling test, adjust the stroke length to 18 mm to simulate localized friction.
Choose the Correct Abrasive Surface
For the abrasion test, use a rough abrasive surface such as synthetic fiber or sandpaper, while for the pilling test, use a soft wool or cloth.
Configure the Test Duration
For the abrasion test, set a longer test duration, while for the pilling test, set a shorter test duration
Run the Test
When you set all the configuration, load the testing specimen into the Martindale test. Recheck the testing procedure, rotation speed, and other parameters as per the testing standard to make sure the test is performed correctly and run the tester.
Monitor and Record Results
After completion of the test, evaluate the testing specimen for signs of wear or pilling as per the rating scale or photograph.
