How the Martindale Abrasion Tester Evaluates Textile Durability through Abrasion and Pilling Resistance
Introduce
In the modern textile industry, product durability and quality are key concerns for consumers. The abrasion and pilling resistance of textiles are crucial indicators of their durability. To scientifically and accurately assess these indicators, the Martindale Abrasion Tester has been developed. This instrument conducts abrasion and pilling tests on textiles, providing a reliable means of quality control for the industry. This article delves into how the Martindale Abrasion Tester evaluates textile durability through abrasion and pilling tests.
The martindale wear and abrasion tester is specifically designed to test the abrasion and pilling resistance of textiles. Its working principle involves securing textile samples in the tester's sample holders and rubbing them against known abrasive materials under low pressure in continuously changing directions. By simulating the wear process in actual use environments, the martindale abrasion testing machine provides test results that closely approximate real-world conditions.
During the test, samples are repeatedly rubbed along a fixed trajectory at a specific speed and pressure. After the rubbing process, the wear and pilling of the samples are observed and measured, compared against standard parameters, thereby evaluating the abrasion and pilling resistance of the textiles.
1. Testing Standards
The abrasion resistance testing of the Martindale Abrasion Tester is widely used in the quality inspection of various textiles and complies with multiple international standards, including GB/T 21196.2, ISO 12947, and ASTM D4966. These standards provide detailed specifications for testing methods, conditions, and result evaluations, ensuring the scientific accuracy and consistency of the tests.
2. Testing Process
In the abrasion resistance test, textile samples are first cut to specified dimensions and secured in the tester's sample holders. The samples are then rubbed against known abrasive materials, such as standard wool fabric or sandpaper. The number of rubs is determined according to the testing standard and specific requirements, typically ranging from thousands to tens of thousands. After the test, the degree of wear on the samples is determined through visual assessment and instrumental measurement.
3. Result Evaluation
The results of abrasion resistance tests are usually expressed in terms of the degree of wear, including surface fiber breakage, the appearance of holes, and the reduction in thickness. Based on the scoring system defined by the standards, the abrasion grade of the textiles is assessed. Higher abrasion grades indicate that the textiles have a longer service life and greater durability in actual use.
1. Testing Standards
Pilling is the formation of small balls of fiber on the surface of textiles due to friction during use. The pilling resistance testing of the Martindale Abrasion Tester also adheres to international standards, including GB/T 4802.2, ISO 12945-2, and ASTM D4970.
2. Testing Process
The pilling resistance testing process is similar to the abrasion resistance test but with a different focus. In the pilling resistance test, samples are similarly secured in the sample holders and rubbed against specific abrasive materials. The number of rubs is set according to the standard requirements, typically several thousand. During the rubbing process, the surface fibers of the samples gradually form small balls.
3. Result Evaluation
The results of the pilling resistance test are evaluated by observing and measuring the degree of pilling on the sample surface. This is typically done using a visual rating method or detailed observation under a microscope. Based on the number, size, and density of the pills, the pilling grade of the textiles is determined. Lower pilling grades indicate that the textiles are less likely to pill during use, maintaining their appearance for longer periods.
The martindale abrasion machine offers several significant advantages in textile testing:
1. High Precision and Repeatability: The Martindale Tester provides highly precise test results, ensuring repeatability and consistency in every test.
2. Multi-Standard Compatibility: It supports testing according to various international standards, making it suitable for textile quality inspection in global markets.
