The principle of the test: acquire 5 round samples with the tested specimen and set them to the specimen holder. Impacted by regular force, the fabric samples and nylon will likely be fuzzing based on the trajectory of round movement and afterwards pilling through the relative friction with regular fabrics (revealed in figure 6).
