How to Properly Use a Martindale Abrasion and Pilling Tester May 12 , 2023

The Martindale Abrasion and Pilling Tester is a widely used instrument in the textile industry to evaluate the abrasion resistance and pilling tendency of fabrics. Proper use of this instrument is essential to ensure accurate and reliable test results. In this article, we will discuss the correct usage of the Martindale tester, including sample preparation, testing parameters, data analysis, troubleshooting, and obtaining accurate test results.

1. Sample Preparation
Before testing, it is crucial to prepare the samples correctly. The abrasion resistance of fabric sample should be taut but not stretched, and any wrinkles or folds should be removed. The backing material should be used to support the sample and to protect the base of the specimen holder from damage. It's also important to remove any loose fibers or threads that may affect the test results.

2. Testing Parameters
The abrasion resistance test fabric tester has several testing parameters that can be adjusted according to the requirements of the test. The most common parameters are the load, the number of cycles, and the speed of the test. The standard load for testing is 9KPa, and the number of cycles is usually set to 1000. The speed of the test can be adjusted depending on the fabric type and the purpose of the test. Higher speeds are usually used for thicker and more durable fabrics.

3. Conducting the Test
Once the test parameters are set, it's time to conduct the test. Place the sample on the test plate and secure it in place. Make sure that the sample is positioned correctly, with the warp and weft threads aligned with the movement of the head.

Next, start the fabric abrasion test machine and let it run for the specified number of test cycles. During the test, monitor the sample for any signs of damage or wear, and record the results.

4. Data Analysis
Abrasion test: The weight loss of the specimen is measured before and after the test, and the difference is calculated as the amount of wear. The wear rate is calculated by dividing the amount of wear by the test duration and the load applied.
Pilling test: The pilling tendency of the specimen is assessed by counting the number of pills formed on the specimen surface after the test. The pill count is typically done using a rating scale of 1 to 5, with 5 being the most severe pilling.

Statistical analysis: It is important to use statistical methods to analyze the test results and ensure their accuracy. This can include calculating the mean, standard deviation, and coefficient of variation for multiple tests, and using regression analysis to examine the relationship between test parameters and test results.

Troubleshooting
Sometimes, the results obtained from the martindale abrasion testing tester may not be accurate due to various reasons such as sample preparation, testing parameters, or instrument calibration. In case of inaccurate results, the following troubleshooting steps can be taken:

1. Check the sample preparation and ensure that it is done correctly.
2. Verify that the testing parameters are set according to the test requirements.
3. Check the instrument calibration and perform necessary adjustments if needed.
4. Repeat the test with a new sample to ensure accuracy.

Proper use of the martindale fabric abrasion test machine is critical to ensure accurate and reliable test results. By following the guidelines provided in this article, users can perform the test correctly, troubleshoot problems, and obtain accurate test results. With accurate test results, textile manufacturers can improve the quality of their products and provide better value to their customers.
