Analysis of Appearance Quality Changes in Martindale Abrasion Testing Machine Test Standards

Martindale abrasion resistance means that a round fabric sample rubs against a standard abrasive material along the movement path of the issajous curve under a certain pressure, causing the sample to be damaged. The wear resistance of the fabric is expressed by the number of times the sample is damaged. . Martindale Abrasion Resistance Tester In GB/T4802, the determination of fabric abrasion resistance - appearance quality change method is suitable for short-lived textile fabrics of life.

The selection of abrasives, sampling methods and coatings of sample holders is consistent with the method of determining damage to woven samples.

First, the total effective mass of the friction charge is (198 ± 2) g; the abrasive replacement cycle: replacing new plastic foams and abrasivesstandard rasives for each test;

Second, the requirements for the appearance change of the evaluation sample:

1) Wear resistanceThe distance test achieves the area change specified in the agreement, and the friction number is used as the measured value of wear resistance. Design appropriate inspection intervals as points to observe changes in sample appearance.

2) The abrasion resistance test is carried out at the number of rubs specified in the agreement, and the surface changes of the sample are evaluated by comparing it with an untested sample of the same fabric.

Finally, there is the description of the test results: Surface changes include fading, linting and pilling. If the end point of the wear resistance test is to obtain the surface changes specified in the agreement, the inspection agreement dmust specify the degree of discoloration, linting and pilling on the surface of the sample. Test results shall be based on the sample achieving the degree of fading, linting and pilling specified in the inspection agreement. Expressed by the number of times of friction. If the end point of the wear resistance test is the number of frictions specified in the agreement, the test result is that after the wear resistance test reaches the number of frictions specified, the post-test sample is compared with the original sample and the degree of fading, linting and pilling of the post-test sample is evaluated. The degree of fading, degree of linting and pilling of the sample after testing accounts for changes in appearance quality.
