Cord Pull Tab

Definition and Overview

A cord pull tab is a component that is operated by holding the loop or end of the cord that is threaded through the slider of a zipper . Because it is softer than metal or resin pull tabs and easier to grip even when wearing gloves, it is used on clothing and bags.

The cord pull tab has a different role from the teeth, slider, top stop, bottom stop, and opening mechanism that make up the zipper. The cord pull tab is an additional part that moves the slider and does not determine the meshing of the teeth or the zipper's opening and closing mechanism itself.

Structure and types

Generally, the cord is threaded through the pull tab hole of the slider to form a loop, and then secured with a knot, a resin cord end, or heat treatment to prevent it from coming loose. In addition to designs consisting solely of cord, some designs combine the cord with a resin or metal knob at the end.

The thickness of the cord, its shape (round or flat), surface smoothness, length, and tip treatment all affect its operability and appearance. While thin cord may appear lightweight, for applications where thick gloves are used, an appropriate thickness and loop size are necessary.

• The loop design makes it easy to grip and less likely to choose a specific direction to pull.
• Short tab-shaped pull tabs are less likely to flap around and are suitable for a simple appearance.
• Cords with cord end are easier to hold and also serve as a design accent.

Main applications

It is used for zipper on the front openings and pockets of blousons, coats, sportswear, and outdoor wear. In bags and cases, it is used to improve the ease of use of the opening.

In particular, when the handle is difficult to grasp, such as with small sliders or water-resistant designs, or when operating with wet hands or gloves, adding a cord handle can make operation easier.

How to choose and points to note

Check that the cord can pass through the pull tab hole on the slider and that the slider moves smoothly after installation. The size of the zipper teeth is a factor in selecting the specifications of the slider and tape, but it is important not to judge the suitability of the cord pull tab by the tooth size alone, but to check the dimensions and shape of the pull tab hole.

The length will be checked in its completed state, including the cord. Measurement standards may differ between the specifications and the material labeling, such as the circumference of the loop, the total length when folded, and the cut length of the cord alone, so the standards will be standardized before ordering.

When sewing, be careful not to sew the cord into the zipper teeth or get it caught in the slider. Check the product for pilling due to washing or friction, loosening of knots, and detachment of the ends.

Differences from similar terms

A pull handle refers to any part of a slider that is operated by pinching it with your fingers. A cord pull handle is a specification in which a cord is added to the pull handle hole or similar location to extend or supplement the operating part. It is not a term that refers to the slider itself.

A cord end is a component that covers the end of a cord to prevent fraying and unraveling. While cord end are sometimes used on cord pulls, a cord end alone is not a component for pulling a zipper. A cord stopper is a component that adjusts and secures the length of a cord, and has a different applications.
