The needle used in the ICI / Mace Snag Tester has an exposed length of 10mm and a tip radius of R0.13mm. These precise specifications are crucial for replicating realistic snag conditions during fabric testing. The needle’s exposed length guarantees that the needle penetrates the fabric surface at an optimal depth, creating snags that accurately reflect those that might occur during regular use.

The tip radius of R0.13mm is carefully designed to balance sharpness and durability. A finer tip radius allows the needle to catch and pull fabric fibers more effectively, simulating the kind of snags that happen when fabrics rub against sharp objects or rough surfaces. The combination of the needle’s length and tip radius assures that the snagging action is both realistic and consistent.
