Hey there! I'm an interlining fabric supplier, and I've seen a lot of folks struggle with ironing interlining fabric correctly. It's not as tricky as it might seem at first, but there are definitely some tips and tricks that can make the process a whole lot easier and ensure you get the best results. In this blog post, I'm gonna share everything I know about how to iron interlining fabric like a pro.
First things first, let's talk about what interlining fabric is. Interlining is a layer of fabric that's used to add structure, stiffness, and body to other fabrics. It's commonly used in garments like jackets, coats, and shirts to give them a more professional and polished look. There are different types of interlining fabrics, including woven, non - woven, and fusible interlinings. For the purpose of this post, we'll focus mainly on fusible interlinings since they're the ones most commonly ironed.
Choosing the Right Interlining
Before you even start thinking about ironing, you need to choose the right interlining for your project. The type of fabric you're using and the end - use of the garment will determine the best interlining for you. For example, if you're working with a lightweight fabric like silk, you'll want a lightweight interlining to avoid adding too much bulk. On the other hand, if you're making a heavy - duty winter coat, a heavier interlining will be more appropriate.
We offer a wide range of interlining fabrics on our website. Check out our Twill Fusible Interlining, which is great for adding a bit of structure to twill - based garments. Our Woven Fusible Garment Interlining Fabric is a versatile option that works well with many different types of fabrics. And if you're looking for something with a strong adhesive quality, our Woven Adhesive Interlining is a top choice.
Preparing Your Workspace
Once you've chosen the right interlining, it's time to set up your workspace. You'll need a clean, flat ironing board covered with a pressing cloth. The pressing cloth is important because it protects both the interlining and the fabric you're applying it to from direct heat and steam. You can use a piece of cotton muslin or a dedicated pressing cloth for this purpose.
Make sure your iron is clean and in good working condition. Fill it with water if you plan to use steam, but test the steam function on a scrap piece of fabric first to make sure it's not spitting or leaving water marks.
Testing the Iron Temperature
Different interlining fabrics require different iron temperatures. It's crucial to test the iron temperature on a scrap piece of the interlining and the fabric you're using before you start working on your actual project. This will help you avoid damaging the fabric or the interlining.
Start with a low temperature setting on your iron and gradually increase it if needed. Press the iron on the scrap piece for a few seconds and then check the result. If the interlining doesn't adhere properly, you can try a slightly higher temperature. But be careful not to go too high, as this can cause the interlining to melt or the fabric to scorch.
Cutting the Interlining
Cut the interlining to the same size as the fabric piece you're applying it to. Leave a little extra room around the edges, about 1/4 inch or so. This extra margin will prevent the interlining from pulling away from the fabric during the ironing process.
Applying the Interlining
Place the interlining on the wrong side of the fabric, with the adhesive side facing the fabric. Make sure it's aligned correctly and smooth out any wrinkles or air bubbles. Then, lay the pressing cloth over the interlining.
Now, it's time to start ironing. Hold the iron firmly and press it down on the pressing cloth. Move the iron in a slow, circular motion to distribute the heat evenly. Apply pressure for about 10 - 15 seconds in each spot, but don't keep the iron in one place for too long.
If you're using steam, you can gently lift the iron and let a little steam out while you're moving it. The steam helps the adhesive bond better, but be careful not to over - steam, as this can cause the fabric to become too wet and the interlining to lose its adhesion.
Working in Sections
For larger fabric pieces, it's a good idea to work in sections. Iron one section at a time, starting from the center and working your way out towards the edges. This will help you keep the interlining flat and prevent it from shifting or wrinkling.
After you've ironed a section, let it cool for a few seconds before moving on to the next one. This allows the adhesive to set properly.
Checking the Adhesion
Once you've finished ironing the entire piece, let it cool completely. Then, gently tug on the edges of the interlining to check the adhesion. If there are any areas where the interlining hasn't adhered properly, you can go back and re - iron those spots.
Finishing Touches
After the interlining has adhered well, you can trim the excess interlining around the edges. Use sharp scissors and cut as close to the fabric as possible without cutting into it.
If you need to sew the fabric after applying the interlining, make sure to use the appropriate needle and thread. A slightly heavier needle and thread may be needed to penetrate the interlining.
Troubleshooting
Sometimes, things don't go as planned when ironing interlining fabric. Here are some common problems and how to fix them:
The interlining doesn't adhere: This could be due to the iron temperature being too low. Try increasing the temperature slightly and re - ironing. Make sure the fabric and the interlining are clean and dry, as dirt or moisture can prevent adhesion.
The interlining is bubbling or wrinkling: This might be because you applied too much heat or pressure in one spot. Try using a lower temperature and a lighter touch when ironing. Also, make sure you're working in sections and letting each section cool before moving on.
The fabric is scorched: This is a sign that the iron temperature was too high. Immediately stop using the iron on the fabric and let it cool. You can try to salvage the fabric by gently rubbing a little bit of white vinegar on the scorched area and then washing it. But in some cases, you may need to start over with a new piece of fabric.
Conclusion
Ironing interlining fabric correctly is an important skill that can take your sewing projects to the next level. By following these tips and tricks, you can ensure that your interlining adheres properly, giving your garments a professional and polished look.
