Reversible Slider

Definition and Overview

A reversible slider is a zipper slider with pull tabs on both the front and back sides. For reversible clothing or bags, the zipper can be opened and closed from either side, regardless of which side is facing outwards during wear or use.

A slider is a component that interlocks or separates the teeth on the left and right sides of a zipper. A reversible slider is a term that describes the shape of the slider itself and does not independently determine the overall type of zipper, the material of the teeth, or how it opens.

Structure and correspondence

While typical sliders have a pull tab on only one-sided, reversible sliders have pull tabs on both the front and back of the garment, or can be operated from both sides. This makes them easy to use even on garments with a right and wrong side, as you don't have to search for a pull tab on the inside.

When using a zipper, it is necessary to combine it with a slider that matches the tooth size, element shape, and tape specifications of the same zipper series. The teeth refer to the continuous components that interlock, and the tape refers to the fabric portion that is sewn onto the fabric.

• The tooth size should match the slider.
• We will check the specifications to ensure compatibility with the type of zipper, such as coil, resin molded, or metal.
• The presence or absence of top and bottom stops and opening mechanisms are selected as part of the overall zipper specifications, separate from the slider.

Main applications and specifications

It is used in jackets, vest, blousons, and coats that can be worn inside out. It may also be used in bags and pouches, taking into consideration whether they are operated from the inside or outside. For front openings in clothing, it is sometimes combined with an open zipper with a pull tab.

The length should be specified by checking the product specifications, including the required zipper length after completion and the top stop, bottom stop, or opening mechanism. Since the measurement standards and display methods for length vary depending on the specifications, it is important to standardize them with the supplier's specifications and sewing specifications.

How to choose and points to note when sewing

During the selection process, we check the thickness of the fabric on both sides, the frequency of use, the required opening and closing strength, and the size of the pull tab. For thick or heavy fabrics, we choose the tooth size by considering the balance between operability and strength, and for thin fabrics, we also check the weight of the slider and how it feels against the fabric.

When sewing, check the direction of the pull tab, the opening and closing direction of the zipper, and the position of the tapes on both sides, with the garment turned inside out. Be careful not to place the seams too close to the teeth, as this can make opening and closing the zipper difficult and may cause the fabric or lining to get caught.

When washing or pre-washing garments, check for opening and closing functionality, deformation of pull tabs, and changes in the appearance of plating or paint using tests that follow the care label. Performing wear tests, including turning the garment inside out, in addition to sewing tests, makes it easier to identify defects.

Differences from similar terms

A double slider is a zipper with two zipper attached. On the other hand, a reversible slider is a part name that focuses on whether a single slider can be operated from the front or back. The two differ in purpose and structure.

A two way separator zipper is a type of zipper that can be opened and closed from different positions, such as the top and bottom. An open-ended zipper is a type of zipper that can be separated into left and right sections using a mechanism at the bottom. reversible sliders can sometimes be combined with these types of zippers.
