Martindale Abrasion Tester Shanghai Qianshi Martindale Abrasion Tester Stock

Product Name:

Shanghai Qianshi Martindale Wear Tester Supply

Application Area:

Shanghai Qianshi Martindale Abrasion Tester Supply Test textile products according to the Martindale method standard system and its relationship, and test the wear resistance of fabrics through this test, and wear resistance is an important indicator of the quality of textile products. affects the durability and use effect of the product Abrasion resistance refers to the property of fabrics to resist wear during repeated friction with other fabrics.

Working principle:

The tissue to be tested is placed in the upper sample holder and rubbed against the abrasive installed on the grinding table. The friction trajectory is a Lissajous figure. After the specified friction phase according to the test requirements, remove the fabric and calculate the abrasion resistance index or evaluate the fuzzing and pilling level ofthe sample through visual description.

Method

1. Sample preparation. In a standard environment, please lay flat for a while and not stretched according to different standards. Such as 24 hours (GB/T 4 80 2 .2-19 97), 16 hours (EN ISO 12947-4:1998)

2. Selection of samples. Cut a piece of sample from several parts of the whole door fabric and the sample should be representative. If it is a beautiful fabric, the sample should include all the different textures and colors presented by the fabric surface;

3. Remove the load and load shaft from the test machine;

4. Remove the top plate and test fixture;

5. Example device: loosen the retaining ring on the test fixture, remove the hold-down piece from the sample and place the sample in the base of the test fixture. When the tested fabric is not more than 500 g/m2, a piece of polyester foam is placed between the sample and the metal block of the sample clamp.last; when it is more than 500 g/m2, or a composite fabric, no foam is required. The samples on each sample holder must be subjected to the same voltage.

6. Wool felt and rubbing cloth device: put the felt and abrasive on the grinding table, put the weight on the abrasive, then put the thrust washer, tighten the nut, so that the thrust washer fixed the abrasive on the grinding table.

7. Place the grinding head on the abrasive and pressurize it;

8. Place the test fixture with the sample facing down on the base fixture and adjust the circle of the test fixture. groove is aligned with the load axis so that the load shaft is inserted into the circular groove of the test fixture;

9. Set the number of times according to the standard, start the switch, start the test , and reach the set number of times Automatic shutdown:

10. Record the sample and compare it to the standard photo in the bassessment box

Comments:

1. The friction cloth cannot be used repeatedly. A friction cloth must be replaced each time a test is completed;

2. The wool felt can be used repeatedly if the surface is worn or stained, needs to be replaced and can be used on both sides;

3. The insole must be dressed first and then the Martindale abrasion test;

4. After the test is completed, the surface of the sample shows abnormalities such as wear, broken yarn, lint, severe pilling, and severe wear, it is judged as unqualified.

5. When preparing samples, pay special attention to avoid hair changes on the cutting edges to avoid unnecessary loss of quality and appearance changes.

6. Pay attention to operating specifications and personnel safety while using the instrument.
