Product Information

Full details

The Milward Concealed Invisible Closed End Zip is an essential tool for home dressmakers and sewing enthusiasts looking to achieve a professional, seamless finish on skirts, dresses, and trousers. This 40cm dark navy zip features a no. 3 coil nylon design that remains hidden within the garment seams, providing a clean look without visible hardware. While perfect for lightweight to medium-weight fabrics, users should ensure their sewing machine is equipped with an invisible zipper foot to properly navigate the coil track during installation.

FAQs

Can I use this zip for heavy denim?

This no. 3 nylon zip is designed for lightweight to medium-weight fabrics; it is not recommended for heavy-duty denim or thick outerwear.

How do I shorten the zip?

You can shorten the zip by sewing a new bar tack across the coil at your desired length and trimming the excess nylon tape below the tack.

Does this zip require a special foot?

Yes, an invisible zipper foot is highly recommended to ensure the seam remains truly concealed.

What is the total length of the zipper?

The total length is 40cm (approximately 15.7 inches).

Is this zip suitable for a center-back dress closure?

Yes, it is excellent for center-back closures, provided the fabric weight is appropriate for the nylon coil.

Troubleshooting

The zipper slider feels stuck or stiff

Check for fabric threads caught in the coil. Gently remove them and apply a small amount of clear wax or a graphite pencil tip to the teeth to lubricate.

The zip is visible through the seam

Ensure your sewing needle is positioned as close to the coil as possible; you may need to use an invisible zipper foot to guide the fabric correctly.

Pros and Cons

Pros

  • Seamless integration into garment seams
  • Lightweight and flexible nylon material
  • Easy to shorten to custom lengths
  • Reliable no. 3 coil ensures smooth operation
  • Matches various dressmaking fabric types

Cons

  • Requires a specialized invisible zipper foot for optimal installation
  • Limited to a 40cm length (unless shortened)
  • Not intended for heavy-duty upholstery or denim fabrics

Setup, Compatibility & Care

To install this zip, use an invisible zipper foot which keeps the coil upright, allowing the needle to stitch as close to the tape edge as possible without hitting the teeth. For best results, use a standard stitch length of 2.0mm to 2.5mm. When ironing, avoid placing a hot iron directly onto the nylon coil, as excessive heat can deform or melt the plastic components; instead, press from the back of the fabric or use a pressing cloth. Always ensure the garment is fully supported when engaging the slider to prevent strain on the coil track.
