EXCELLA

Definition and Overview

EXCELLA is a type of metal zipper with smoothly finished teeth. It is characterized by the refined sheen of the teeth and the smooth feel when opening and closing, and it is also used as a visible trim to add a design accent.

Like a standard metal zipper, it consists of a zipper tape, interlocking teeth on the left and right, a slider for opening and closing, top stops and bottom stops that secure the ends, or a pin and box.

Structure and Specification Types

The tooth size is selected according to the application, required strength, and the desired visual presence. Larger teeth tend to create a stronger design effect and presence, but for thin fabrics or small pockets, it is necessary to check the balance with bulk and stiffness.

Specifications include closed-end zippers with a closed bottom, open-end zippers that can be separated left and right, and two-way separator or double-slider types that can be opened and closed from the top or bottom. The shape of the slider and pull tab, as well as the color combination of the teeth and tape, also affects the product's appearance.

The zipper length generally refers to the interlocking section of the teeth from the top stop to the bottom stop, or from the top stop to the pin and box in open-end types. It differs from the full tape length, so specifications should list both the length basis and the opening type.

• Closed-end: the bottom end is closed, used for pockets and the front openings of pants.
• Open-end: the bottom end can be separated by the pin and box, used for front openings on outerwear.
• Two-way separator: a specification that can be opened and closed from the bottom as well by means of multiple sliders.

Main Applications

It is used for garments where the metallic sheen should be shown as part of the design, such as jackets, coats, blousons, and leather jackets. It is used not only for front openings, but also for cuffs, chest pockets, side pockets, and slits at the hem.

For bags and small items, it is chosen when the design of the opening and closing area should be enhanced. The tooth size and slider specification are determined by considering the thickness of the textile or leather, the overlap of sewn sections, and the load from the contents.

Selection, Sewing, and Handling Notes

When selecting, check the required opening style, zipper length, tooth size, tape color, and slider shape for the application. If the fabric is thin or highly stretchy, fusible interlining or stay tape may be used together to suppress stretching and waviness around the zipper.

During sewing, set the stitch position so that the needle does not hit the teeth or slider, and make sure the seam allowance thickness does not interfere with opening and closing. In particular, metal teeth are hard, so care is needed to avoid needle breakage or damage to the teeth from needle contact.

Before washing or dry cleaning, close the zipper to reduce contact with other items. Since the appearance may change due to chemicals, sweat, water, or other factors, it is important to conduct advance testing with the actual fabric, washing conditions, and trim combination.

Differences from Similar Terms

A metal zipper refers broadly to any zipper with metal teeth, while EXCELLA is a type within that category characterized by the sheen and smoothness created by the finished teeth. Not all metal zippers have the same appearance or opening and closing feel.

A coil zipper uses coiled synthetic resin teeth, while a Vislon zipper uses injection-molded synthetic resin teeth. A concealed zipper refers to a structure in which the teeth are not easily visible from the front when closed, and it is not a name that indicates the tooth material or surface finish.

Frequently Asked Questions

Where should the length of EXCELLA be measured?

Generally, it is measured by the interlocking length of the teeth from the top stop to the bottom stop, or from the top stop to the pin and box in open-end specifications. It is not the full length from one end of the tape to the other. In orders and specifications, confirm the opening type such as closed-end, open-end, or two-way separator in addition to the length.

Can EXCELLA be used on thin fabrics?

Yes, but the weight and stiffness of the metal teeth, as well as waviness around the seams, may become noticeable. Choose a tooth size that matches the fabric thickness and strength, and if necessary reinforce the sewn area with fusible interlining or stay tape, then confirm the opening and closing performance with a sample.

What is the difference between a metal zipper and EXCELLA?

A metal zipper is the general term for zippers that use metal teeth. EXCELLA is a type within that category, characterized by smoothly finished teeth and a glossy, smooth opening and closing feel. When selecting it, check not only the appearance but also the opening style, length, and tooth size.
