Reverse Coil Zipper
Reverse Coil Zipper
Identification of a basic or a reverse zipper is easy. It is a regular coil zipper if the front side of the zipper together with its teeth, slider and puller are visible. However, if the coil is on the side of zipper with the slider performing on the flatter side, then it is a reverse coil zipper. Stitches on the reverse coil zippers are visible from the front side. These zippers are extremely useful for waterproof functionalities with the involvement of PVC or rubber coating.
In this category of zippers, teeth are hidden behind the tape. Concealed zippers are also known as invisible zippers. These zippers are the best and elegant looking ones as they are not visible except for the pull tab. Most of the times, light fabrics are used on the zipper tape instead of the usual heavy woven fabrics.
Concealed zippers are very easy to insert and the stitching is also done from the inner side. Such zippers are widely used in skirts and dresses. Here, colour of the tape matches with the garment and even the slider and puller. The use of concealed zippers has also begun by the military and emergency agencies.
There is a huge difference between reverse and reversible zippers. Operation is smoother with reversible zipper as it can be operated from both the sides. Its pull tab has the ability to flip to the other side of the slider along the rotating rail. These zippers are great for reversible projects.
