[0002] The core function of a zipper is to quickly, reliably, and repeatedly open and close two pieces of flexible material (usually fabric), thus replacing traditional closure methods such as buttons and ties. Its necessity is reflected in four dimensions: efficiency, reliability, sealing, and aesthetics. It is an irreplaceable "invisible infrastructure" in modern clothing, equipment, and industrial products.
