Abrasion Tester is used to determine the abrasion resistance of fabrics when rubbed against a standard abradant or a wire mesh screen with a backward and forward motion over a curved surface. Particularly it’s suitable for? automotive and furniture industry fabric manufacturers working to US standards.
Test Procedure:
At first cut the fabric into 4 pieces according to the measurement of the instrument.
Weigh these 4 pieces of fabric samples.
Now place these samples in the instrument under a certain load as supplied in the instrument.
Now start the machine and observe the counter of abrasion no.
After an abrasion of 200 bring out the first sample and weigh it.
After an abrasion of 300 bring out the second sample and weigh it.
Similarly after abrasion of 400 and 500 bring out the third and fourth sample and take their weight.
Now put the weights before and after abrasions in a table and find out their wear index.
