About this deal

Knowing the anatomy of a zipper is important. It helps you to understand how each component works together to make a functional zipper. This is useful information when selecting the right zipper option for your project. The downside to coil zippers is that the thin teeth can be prone to getting bent or damaged over time. Molded Plastic Zippers Zippers are sized by measuring the width of the teeth, while the zipper is closed, in millimeters. So, a #5 zipper has 5mm wide teeth. That seems easy enough, right? But why does this matter? Also, knowing what each part of a zipper is can help you to find the right replacement pieces when repairing a zipper. Non-separating zippers don't come apart completely. Sometimes the bottom of the zipper doesn't come apart and sometimes both the top and bottom remain attached.

A head-to-head zipper is a type of two-way zipper with sliders that are facing towards each other on the tape. To close a head-to-head zipper, the sliders must be pulled in towards each other, while to open the zipper they are pulled apart.Now that you know the anatomy of a zipper, let's take a look at the different zipper options available. There are 4 primary types of zippers, all of which can be found in both separating and non-separating varieties. Metal zippers are perfect for bags, pants, and outerwear that will receive a lot of wear and tear. However, there are a few negatives to using metal zippers.

In addition, metal zippers often don't hold up as well out in the elements (especially rain) as other types of zippers. This type of zipper is probably not your best choice for outdoor furniture or a rain coat! Invisible Zippers First, the teeth of an invisible zipper are curled underneath the tape, hiding them from view. In addition, the slider is usually very narrow to allow it to hide easily within a seam. Many zippers, especially those used on bags and luggage have two sliders on the zipper teeth. These are two-way zippers. One-Way Zippers Double zipper sliders are somewhat similar to reversible sliders in that they work from both sides. However, instead of having a pull tab that moves from one side to the other, they have two tabs - one on each side.In addition, the teeth of molded zippers have a tendency to pull apart and separate while closed if pressure is placed on the zipper. This makes them a bad choice for bags that may get overstuffed. Metal Zippers

The teeth of coil zippers are made from thin pieces of plastic that have a coil-like appearance. These teeth are stitched to the zipper tape with thread. These 2 types of zippers have slightly different parts because they function differently. The Parts of a ZipperMost sewing patterns don't recommend a zipper size, they just give you a length. So you'll have to choose the size yourself! Keep this in mind while selecting a zipper size: the larger the size, the wider and more conspicuous the teeth will be - and the heavier the zipper will be. While "reversible sliders" may sound like it should be the same thing as "reverse sliders" - it's actually something completely different! Most sewing patterns will recommend a length of zipper for the project. To find the length of a zipper, measure from the top stop to the bottom stop. Or, if you're using a separating zipper, from the top stop to the retaining box. Most zippers can be separated into 2 overarching categories: separating zippers and non-separating zippers. Coil zippers are flexible and lightweight, making them perfect for sewing into curved seams. They are also resistant to pulling apart while closed. This is great when making bags or luggage that may get overstuffed and put pressure on the zipper.
