What Is The Difference Between Coil And Metal Chain Zippers
Regardless of zipper type, whether conventional, invisible or separating, all zippers are constructed of either plastic coils or metal chain. The choice of which type of zipper to use should be made considering the garment design and type of zipper application.
Plastic coils are constructed of a specialized polyester or nylon material and shaped into a spiral structure which is essentially twisted into the zipper tape. Zippers with plastic coils are the most widely used in dressmaking providing a strong, durable closure that is lighter and more flexible than that of a metal chain zipper. Coil zippers are also available in a lot more color variations and are available in both conventional and invisible styles.
Metal chin zippers are constructed of alternating links that are wider in size and have a more "spread-out" appearance. Metal chain can be used with both closed-end and separating zippers and available in a few different metallic shades including bronze, silver, gold, black, and brown. While the woven zipper tape can be found in a multitude of colors, the metal chain itself is inly limited to metal tones. Metal chain zippers are often used in a semi-decorative exposed fashion to contribute to the garment's visual design. These zippers are less malleable than its coils counter part and due to their heftier weight, are often used in heavier duty applications.
