ICI / Mace Snag Tester Working Principle
The Mace Snag Tester is designed to simulate the snagging that fabrics might experience during regular use. Here's a simplified explanation of how it works:
-
Sample Preparation: A piece of fabric is cut to a specific size and placed on a rotating drum inside the tester.
-
Hammer Placement: A hammer, which is attached to the machine by a chain, is placed so that it rests on the surface of the fabric sample.
-
Drum Rotation: The drum starts rotating at a constant speed. As it turns, the hammer is dragged along the fabric, but because it's suspended by a chain, it flips and bounces around unpredictably.
-
Snagging Action: As the hammer moves across the fabric, it catches on the fabric's fibers, creating snags or pulls (i.e., it pulls threads out of the fabric).
-
Test Duration: The drum continues to rotate for a set number of cycles, allowing the hammer to create snags across the entire surface of the fabric sample.
-
Evaluation: Once the test is complete, the fabric is removed, and the number and severity of the snags are assessed. This is typically done by comparing the tested fabric to a set of standard reference fabrics that show different levels of snagging.
-
Rating: The fabric is then given a snagging rating based on how it compares to these standards, indicating how likely it is to snag during normal wear
