Attaching garment interlining to fabric is a crucial step in the garment manufacturing process, as it can significantly enhance the shape, durability, and overall quality of the final product. As a garment interlining supplier, I've witnessed firsthand how the right interlining and proper attachment techniques can transform a simple piece of fabric into a high - end garment. In this blog, I'll share some key steps and tips on how to attach garment interlining to fabric effectively.
Understanding the Types of Garment Interlining
Before we delve into the attachment process, it's essential to understand the different types of interlining available. We offer a wide range of interlinings, including Shirt Interlining, Collar Interlining, and Jacket Interlining.
Shirt interlining is typically lightweight and used to provide structure to shirt collars, cuffs, and plackets. It helps maintain the shape of these areas without adding too much bulk. Collar interlining, on the other hand, is specifically designed to give collars a firm and crisp appearance. It can be adjusted in stiffness depending on the style of the shirt or jacket. Jacket interlining is often heavier and is used to add body, warmth, and durability to jackets. It can also help the jacket hold its shape over time.
Preparing the Fabric and Interlining
The first step in attaching garment interlining to fabric is to prepare both the fabric and the interlining.
1. Cutting
Cut the interlining and the fabric pieces to the same size and shape. It's important to be as accurate as possible during this step. Use sharp scissors or a rotary cutter to ensure clean edges. When cutting, make sure to follow the grainline of the fabric. The grainline of the interlining should also match that of the fabric to prevent distortion when the garment is worn.
2. Marking
Mark any necessary notches, darts, or seam allowances on both the fabric and the interlining. This will help you align the pieces correctly during the attachment process. You can use tailor's chalk, disappearing ink pens, or small pins to make these markings.
3. Testing the Adhesion
If you're using fusible interlining, it's crucial to test the adhesion on a scrap piece of the same fabric and interlining. This will help you determine the correct temperature, pressure, and time settings for your iron. Different fabrics and interlinings may require different settings, so it's always better to test first to avoid any damage to the actual garment.
Attaching the Interlining: Fusible vs. Sew - in
There are two main methods of attaching garment interlining to fabric: fusible and sew - in.
Fusible Interlining
Fusible interlining is the most common method used in garment manufacturing today. It has a heat - activated adhesive on one side that bonds to the fabric when heat and pressure are applied.
Step 1: Placement
Place the fusible side of the interlining against the wrong side of the fabric. Make sure the pieces are aligned accurately, using the markings you made earlier. You can use pins to hold the pieces together temporarily, but be careful not to leave the pins in place when you start ironing, as they can damage the iron and the fabric.
Step 2: Ironing
Set your iron to the appropriate temperature for the fabric and interlining combination. Place a pressing cloth over the fabric to protect it from direct heat. Apply firm, even pressure with the iron, moving it in a smooth, circular motion. Start from the center of the piece and work your way out to the edges. Make sure to cover the entire surface of the interlining.
The time and pressure required will depend on the type of interlining and fabric. Generally, you'll need to press for about 10 - 30 seconds per area. After ironing, let the fabric cool completely before handling it. This will allow the adhesive to set properly.
Sew - in Interlining
Sew - in interlining is a more traditional method and is often used for heavier fabrics or when a more permanent attachment is required.
Step 1: Basting
Pin the interlining to the wrong side of the fabric, aligning the markings. Use a long, loose stitch (basting stitch) to hold the two pieces together. Start from the center and work your way out to the edges. This will prevent the interlining from shifting during the actual sewing process.
Step 2: Sewing
Once the pieces are basted together, you can sew them using a regular sewing machine or by hand. Use a stitch length appropriate for the fabric and interlining. A medium - length stitch (about 2.5 - 3 mm) is usually a good choice. You can sew along the edges of the pieces or use a grid pattern of stitching to secure the interlining more evenly.
Post - Attachment Steps
After attaching the interlining to the fabric, there are a few additional steps to ensure the best results.
Pressing
Press the attached fabric and interlining again to set the stitches and smooth out any wrinkles. Use a pressing cloth and the appropriate temperature setting for the fabric. This will help the garment look its best and also improve the overall durability of the attachment.
Trimming
Trim any excess interlining or fabric from the edges. This will make the seams neater and reduce bulk. Be careful not to cut too close to the stitches, as this could cause the interlining to come loose.
Troubleshooting Common Issues
1. Bubbling or Wrinkling
If you notice bubbling or wrinkling in the interlining after attachment, it could be due to incorrect ironing temperature or pressure. Try re - pressing the area with a lower temperature and more even pressure. If the problem persists, you may need to remove the interlining and start over.
2. Poor Adhesion
If the fusible interlining doesn't adhere properly, it could be because the iron wasn't hot enough, the pressure was too light, or the fabric was too thick or textured. Try increasing the temperature slightly and applying more pressure. You can also try using a steam iron to help the adhesive bond better.
3. Distortion
Distortion can occur if the grainlines of the fabric and interlining don't match or if the interlining is stretched during the attachment process. Make sure to cut and align the pieces accurately, and handle them gently to avoid stretching.
Conclusion
Attaching garment interlining to fabric is a skill that requires practice and attention to detail. By understanding the different types of interlining, preparing the fabric and interlining correctly, choosing the right attachment method, and following the post - attachment steps, you can achieve excellent results.
