Hey there! As a garment interfacing supplier, I often get asked about the best temperature for fusing garment interfacing. It's a crucial question because getting the temperature right can make or break the quality of your finished garment. In this blog post, I'll share some insights and tips to help you find that sweet spot.
First off, let's understand what garment interfacing is. Interfacing is a layer of fabric that's used to add strength, stability, and shape to different parts of a garment. It can be used in collars, cuffs, waistbands, and even in the bodice of a dress. There are different types of interfacing, like Embroidery Back Interlining, Interlining Fabric, and Fusible Interlining. Fusible interlining is the most common type, and it's the one we'll focus on when talking about fusing temperatures.
The temperature for fusing fusible interlining depends on several factors. One of the main factors is the type of adhesive used on the interlining. Different adhesives have different melting points, which means they require different temperatures to bond properly with the fabric. For example, some adhesives are designed to work at lower temperatures, around 120 - 140°C (248 - 284°F). These are usually used for delicate fabrics like silk or chiffon, where higher temperatures could damage the fabric.
On the other hand, if you're working with heavier fabrics like denim or wool, you might need a higher temperature, around 160 - 180°C (320 - 356°F). The heavier fabric can withstand the higher heat, and the stronger bond created by the higher temperature is necessary to hold the interlining in place.
Another factor that affects the fusing temperature is the type of fabric you're using. As I mentioned earlier, delicate fabrics need lower temperatures. Fabrics with a high synthetic content might also require a different temperature than natural fabrics. Synthetic fabrics can melt or warp at high temperatures, so it's important to test a small piece first.
Let's talk about how to test the fusing temperature. Before you start fusing the entire garment, it's a good idea to do a test on a scrap piece of the same fabric and interlining. Cut a small square of the fabric and the interlining, and place the interlining, adhesive side down, on the fabric. Then, use a pressing cloth to protect the fabric from direct heat, and press a hot iron on the fabric for a few seconds. Check the bond between the interlining and the fabric. If the bond is weak, you might need to increase the temperature slightly. If the fabric looks damaged or the interlining has melted too much, you need to lower the temperature.
It's also important to consider the time of pressing. Even if you have the right temperature, if you press for too long, you can still damage the fabric. Usually, a few seconds of pressing is enough. You can press multiple times if needed, but make sure to give the fabric and interlining time to cool between presses.
Now, let's get into some specific examples. If you're using a lightweight cotton fabric for a blouse and a lightweight fusible interlining, a temperature of around 130 - 150°C (266 - 302°F) should work well. Press the iron gently for about 5 - 8 seconds, and you should get a good bond.
For a denim jacket, where you need a stronger bond, set your iron to around 170 - 190°C (338 - 374°F). Press for a bit longer, about 8 - 10 seconds, but make sure to move the iron around to avoid overheating one area.
When it comes to wool, it's a bit tricky. Wool is a natural fiber, but it can be sensitive to heat. A temperature of 150 - 170°C (302 - 338°F) is usually a good starting point. You can also use a steam iron on a low setting to help the interlining bond better without damaging the wool.
In addition to the iron, there are also some other fusing tools available. Some industrial fusing machines can provide more precise temperature control and pressure. These machines are great for large - scale production, but for home sewers or small - scale manufacturers, an iron is usually sufficient.


To sum it up, finding the best temperature for fusing garment interfacing is a process of trial and error. You need to consider the type of adhesive on the interlining, the type of fabric, and do a test before you start the actual fusing. By taking these steps, you can ensure that your garment has a strong, durable bond between the fabric and the interlining.
