AATCC 93 Test Method for Abrasion Resistance of Fabrics: Accelerotor

Purpose of Test

This test determines the resistance of the fabric from wearing away due to applied friction.

Terminology Defined

Abrasion – The process of wearing the textile surface away as a result of applied friction force.

Abrasion Resistance – The measurement of how the fabric resists abrasion, leaving no trace of change in the textile surface.

Accelerotor – A machine used to test the abrasive resistance of textiles.

Test Method

Materials Used for Test

  • Test specimen
  • Accelerotor
  • Liner
  • Neon lamp  or other stroboscopic devices
  • Timer
  • White glue
  • Pinking shears, marking templates, or cutting dies
  • Brush
  • Thread
  • Cotton Fabric
  • Analytical Balance

Testing Procedure

The test specimen is tested using an accelerotor. Abrasion is applied to the specimen by rubbing yarn against the yarn, surface against the surface, and surface against abradant.

During the test, the fabric is subject to

  • Flexing
  • Rubbing
  • Shock
  • Stretching
  • Compression
  • Other mechanical force

Test Procedure (Summary)

Part 1: Preparation of test specimen and accelerotor:  The test specimen is prepared under varying test conditions and weighed on the analytical balance. The accelerotor is set up.

Part 2: Testing with the accelerotor: The test specimen is crumpled and placed in the accelerotor under varying conditions. 

Part 3: Evaluation: After the run, the test specimen is vacuumed and reweighed on the analytical balance.
