This zipper is a type of fastener that is used to join two pieces of fabric or other material. It consists of two rows of interlocking teeth that are joined together by a slider. The slider is a small piece of metal that is moved up and down the zipper to open or close it. Nylon zippers are made by extruding molten nylon through a spinneret. The spinneret is a device with small holes that create the fibers. The fibers are then spun into yarn and woven or knitted into a tape. The teeth of the zipper are then formed on the tape. This zipper can be used on pants, skirts, dresses, jackets, and other clothing items.
