Abrasion Resistance Testing During daily use, the High-Visibility Reflective Safety Vest may be subjected to friction against various objects—such as tools, walls, and floors—making its abrasion resistance of paramount importance. An abrasion testing machine is employed to conduct friction tests on the garment's surface under specified pressure and for a prescribed number of cycles (e.g., 5,000 cycles under a specific load). Following the test, the garment's surface is inspected for any signs of damage, detachment of reflective materials, or degradation in reflective performance. The requirement is that, even after undergoing abrasion testing, the reflective clothing must continue to meet basic visibility and protective performance standards, thereby ensuring its durability within actual working environments.

Wash Durability Testing To simulate the washing conditions encountered during the garment's daily use, wash durability testing is conducted. Samples are subjected to multiple washing cycles (e.g., 50 times or more) in accordance with standardized washing procedures (which specify factors such as the type of detergent, water temperature, wash duration, and mechanical agitation intensity). After each washing cycle, the garment's physical appearance is examined for any signs of deformation, loose stitching, or color fading; simultaneously, its reflective performance is measured to detect any decline. Upon completion of the prescribed number of washing cycles, the garment's retroreflective coefficient must remain above a certain threshold (e.g., at least 70% of its initial value) to ensure that it continues to function effectively as a reflective safety garment even after repeated laundering.
