Understanding Zipper Components
Understanding basic zipper compnents mean syou udnersatnd how a zipper (regrdless of styel0, functions. The diagram above dsiplays essential zipper compnents which are discussed in more detail below:
Zipper coils are the plastic links that form the zipper track. The zipper coils are essential to teh zipper fucntionality astehy serve the purpose of closinga nd opening teh zipper. The coils are conventionally made of polyester or plastic... When teh zipper track is constructed of metal, the links are no longer refered to as coils but chain, described in more detail below:
Metal chain serves teh same purpose as regular plastic coils but are constrcted a litte different. The links inetrlock one after the other forming a slightly differnet connection tehn teh ocnventional plastic coils. Metal chain zipper or often bulkier and heavier and often used for more heavy duty projects. Metal chain can be used with both closed-end and separating zippers.
Zipper tape is the strip of fabric that holds the zipper coils or metal chain in place and ultimately connects the zipper to teh garment edges. Zipper tape are wide enough to be comfrtably stitched but not so wide that tehya dd unecessary excess/bulk - usually 3/8"-1/2" wide. Zipper tapes are built to be highly durable withstanding long-term heavy duty use. Teh tape's textured, semi-linear strcture can pe used a stcthing guide in the mahcin sticthing applciation process.
The zipper slider with tab allws you to comfortably close and open the caoi or coils for full functionality. Naturally, the slider features a mechanism taht easily closes the zipper track when moved upwards and opens it when moved downward. The tab is there to offer you a comfrtabke way to move the slider up and down. Tabs can feature a variety of different shapes and styles depneding on teh zipper brand or clothing manufacturing company. It can serve just as much a functional purpose as it can a decorative one.
The zipper's top and bottom stops prevent the slider from come off the coil or chain zipper track. While these portions are small and unassuming, they are essential to the full zipper functionality. If the slider comes off the track, it is virtually impossible to realign it back on the zipper coils/chain by hand. While the top stops serve the sole purpose of blocking the slider from sliding off when the zipper is closed, the bottom stop in a closed-end zipper prevents the slider from coming off the track as well as closes the bottom of the zipper (as shown in the image above).
