A separating zipper (also called an open-end zipper) is a type of zipper that completely opens at the bottom, allowing the two sides of the garment to separate fully when unzipped.
Here’s a clear description:
Structure:
It has a special mechanism at the bottom—a box and pin—that lets the zipper halves come apart.
The zipper teeth (metal, plastic, or nylon) are attached to fabric tapes.
The slider moves up to close and down to open the zipper.
Function:
A separating zipper allows the garment or item to open flat, making it easy to put on or take off.
Common uses:
Jackets and coats
Hoodies and sweatshirts
Vests
Sportswear and outerwear
