Abrasion Resistance Tester

Abrasion Resistance Tester

To determine the abrasion resistance of the sample fabric.

A number of important points require consideration before abrasion resistance tests are carried out. The choice of the method may be governed by the type of apparatus available, the precision demanded and so forth. Some of the more important points are condition of the specimen, choice of testing instrument, choice of abrasive motion, direction of abrasion, choice of abradant, backing the specimen, cleanliness of the specimen and instrument, tension on the specimen, pressure between abradant and specimen, end-point of the test etc. Now there are various abrasion resistance testing instruments available for example, the WIRA abrasion tester, the LIRA abrasion tester, the Taber abraser, the Shiefer machine, the Wyzenbeek abrasion tester, the Stoll universal wear tester, the LINRA wear tester, the BFT abrasion tester etc. The abrasion tester we used here is made by Qinsun Instrument. In this instrument abrasion surfaces wrapping by sand paper are used to abrade the fabric samples. A counter is used to count the no. of abrasion. This is an electrical tester.

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.

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.
