The digital Martindale abrasion and pilling tester is an advanced device used to evaluate the abrasion resistance, pilling (fiber breakage forming a fuzzy surface), and pilling (fiber entanglement into small balls) performance of textiles, fabrics, and other similar materials under repeated friction. This tester achieves precise control and real-time monitoring of the testing process through a digital control system and precise sensors. The following is a detailed introduction to the digital Martindale abrasion and pilling tester:
1. Working principle
The working principle of the digital Martindale abrasion and pilling tester is similar to that of the traditional Martindale tester, but it provides higher accuracy and automation level through a digital control system and sensors. The specific steps are as follows:
one
Sample preparation:
Sample size: Cut the fabric sample to be tested into standard sized circular samples, typically with a diameter of 38mm or 140mm.
Fixed sample: Fix the sample on the testing fixture to ensure that it does not move during the testing process.
two
Friction action:
Friction head: The friction head of the tester (usually a 28mm diameter wool felt or rubber pad) performs reciprocating friction on the surface of the specimen with a specific trajectory and pressure.
Motion trajectory: The motion trajectory of the friction head is in the shape of an "8", simulating the wear situation in actual use.
three
Cycle times:
Set the number of cycles: According to the testing standards, set a certain number of friction cycles. The digital control system can accurately control the number of cycles, ranging from hundreds to tens of thousands.
four
Digital monitoring:
Real time monitoring: By using sensors and digital control systems, parameters such as pressure, speed, and number of cycles during the friction process can be monitored in real-time.
Data recording: Automatically record various data during the testing process, including friction frequency, quality changes, pilling and pilling conditions, etc.
five
assessment:
Wear resistance evaluation: After the test is completed, evaluate the quality loss and degree of damage of the sample.
Quality loss: calculated by measuring the change in mass of the sample before and after testing.
Degree of damage: evaluated through visual inspection or using standard rating charts.
Assessment of fuzz: Evaluate the degree of fiber breakage and fuzz on the surface of the specimen.
Ball formation assessment: Evaluate the entanglement of fibers on the surface of the sample into small balls.
