How to Choose the Right Slider to Repair a Broken Zipper

A Step-by-Step Guide to Identifying Your Zipper Type and Size

If you've ever had a zipper break on a favourite piece of clothing or a valuable item, you know how frustrating it can be. Fortunately, fixing a broken zipper is often a simple process that doesn't require professional help. In many cases, all you need to do is replace the slider. However, with so many types of zippers and sliders available, it can be challenging to know which one to buy. In this blog post, we'll walk you through the process of establishing what slider to buy to repair a broken zipper.


Step 1: Determine the Type of Zipper You Have

The first step in determining what slider to buy is to identify the type of zipper you have. There are three main types of zippers: coil, plastic molded, and metal. Coil zippers have a continuous coil that is sewn onto the fabric, while plastic molded zippers have teeth that are molded onto the zipper tape. Metal zippers have individual metal teeth that are joined together by a slider. Look closely at the zipper and determine which type you have.


Step 2: Identify the Size of the Zipper

Once you've determined the type of zipper you have, you need to identify the size. Zippers come in different sizes, measured in millimetres. The easiest way to determine the size of the zipper is to look at the back of the existing slider and find the size number. This number will indicate the size of the zipper teeth and the size of the slider you need.


However, if you don't have the old slider or the size number is not visible, you can also measure the width of the teeth when fastened. Use a ruler to measure the distance between the teeth when fastened at the widest point. Once you have the measurement, the width in millimetre refers tot eh size i.e. a 3mm width is  size #3 zip, 5mm a size #5 zip ad so on


It's important to note that the size of the zipper determines the size of the slider you need, so it's essential to measure accurately. If you choose the wrong size, the slider may not fit properly, and the zipper may not work correctly.

By following these steps, you can establish the correct size of zipper and choose the appropriate slider to repair a broken zipper. Remember to identify the type of zipper, measure the size of the teeth or refer to the size number, and choose a slider that matches the size, shape, and material of the original slider. With the right tools and materials, you can quickly fix a broken zipper and extend the life of your favourite items.

This article delves deep into the features, types, and tips for using nylon coil zips in bag making, ensuring your creations are not only functional but also visually appealing. What Are Nylon Coil Zips? Nylon coil zips, often referred to as nylon zippers , are a type of zipper with teeth made from coiled nylon filament. Unlike metal or moulded plastic zippers, the teeth of nylon coil zips are flexible and lightweight, making them ideal for applications requiring smooth operation and adaptability. Key Characteristics of Nylon Coil Zips Durability : The coiled nylon teeth are resistant to wear and tear, making them perfect for daily-use bags. Flexibility : Their soft and pliable design ensures they can curve seamlessly, suitable for designs with rounded edges. Variety of Sizes : Available in a range of widths, from delicate #3 zippers for small pouches to sturdy #5 and #10 zippers for heavy-duty bags. Colour Options : Nylon coil zips come in a spectrum of colours, allowing for perfect coordination with fabrics. Ease of Use : They are easy to sew into projects, whether by hand or machine. Why Nylon Coil Zips Are Perfect for Bag Making Versatility in Design Nylon coil zips can adapt to various bag styles, from compact clutches to large travel duffels. Their flexibility makes them an excellent choice for: Backpacks : Offering durability to withstand heavy loads. Handbags and Totes : Adding a sleek, professional finish. Cosmetic and Toiletry Bags : Resistant to moisture, ensuring contents stay protected. Laptop Sleeves : Providing a secure yet smooth closure. Durability for Everyday Use Bags often endure significant strain, especially at the zipper area. Nylon coil zips are designed to handle frequent usage without compromising functionality.

Types of Nylon Coil Zips for Bag Making Closed-End Nylon Coil Zips These zips have a stopper at the end, preventing the slider from detaching. They are ideal for pockets, small pouches, and fixed closures. Open-End Nylon Coil Zips Designed for applications where the zip needs to separate completely, such as jackets or expandable bags. Continuous Nylon Coil Zips These are long zipper tapes without pre-attached sliders, allowing you to cut the desired length. Continuous zippers are cost-effective and versatile for large projects. Tips for Using Nylon Coil Zips in Bag Making Selecting the Right Size The size of the zipper is determined by the width of its coil. Use: #3 Zippers for lightweight bags and interior pockets. #5 Zippers for handbags, totes, and medium-sized bags. #10 Zippers for heavy-duty duffels and travel bags. Preparing the Zipper Trim the zipper tape to the required length if using a continuous zipper. Apply a small amount of fabric glue to prevent fraying at the edges. Test the slider to ensure smooth movement before sewing. Sewing Techniques Use a zipper foot on your sewing machine for precise stitching. Secure the zipper with basting tape or pins before stitching to avoid misalignment. For curved edges, snip small notches into the zipper tape to allow it to bend smoothly. Adding Reinforcements Reinforce the ends of the zipper with bar tacks to enhance durability, especially for bags carrying heavy loads. Common Problems and Solutions When Using Nylon Coil Zips Problem: Slider Sticks or Catches Solution : Apply a small amount of zipper lubricant or wax along the coil for smoother operation.

Avoid Overloading : Excessive strain can damage the zipper teeth or slider. Lubricate Occasionally : A dab of silicone lubricant keeps zippers running smoothly. Conclusion Incorporating nylon coil zips into your bag-making projects offers unparalleled versatility, durability, and style. From their flexible design to their wide range of applications, nylon coil zips are an indispensable tool for crafters and professionals alike.
