Repairing damaged bonded interlining in a garment is a crucial skill that can extend the lifespan of your clothing and maintain its quality. As a bonded interlining supplier, I've encountered various issues related to damaged interlining and have learned effective repair methods. In this blog, I'll share some practical tips on how to tackle this problem.

Understanding Bonded Interlining

Before delving into the repair process, it's essential to understand what Bonded Interlining is. Bonded interlining is a layer of fabric that is attached to the main fabric of a garment to provide structure, shape, and support. It is commonly used in collars, cuffs, waistbands, and other areas that require stability. There are different types of bonded interlining, such as PA Interlining and PET Interlining, each with its own characteristics and applications.

Causes of Damaged Bonded Interlining

Several factors can lead to damaged bonded interlining. One common cause is improper washing or dry cleaning. High temperatures, harsh detergents, and aggressive agitation can weaken the bonding between the interlining and the main fabric, causing it to delaminate. Another cause is wear and tear over time. Frequent bending, stretching, and rubbing can also damage the interlining, especially in areas with high stress, such as the elbows and knees. Additionally, poor-quality interlining or incorrect bonding during the manufacturing process can contribute to premature damage.

Assessing the Damage

The first step in repairing damaged bonded interlining is to assess the extent of the damage. Carefully examine the garment to determine where the interlining has delaminated or become damaged. Look for signs of separation, such as loose edges, bubbles, or wrinkles in the fabric. You may also notice a change in the texture or stiffness of the affected area. Once you have identified the damaged areas, you can decide on the appropriate repair method.

Repairing Minor Damage

For minor damage, such as small areas of delamination or loose edges, you can often repair the interlining yourself using a simple adhesive. Here's a step-by-step guide:

  1. Prepare the Garment: Lay the garment flat on a clean, smooth surface. Make sure the damaged area is free of dirt, dust, and debris.
  2. Choose an Adhesive: Select an adhesive that is suitable for bonding fabric. Look for a fabric glue or a fusible web that is compatible with the type of interlining and the main fabric.
  3. Apply the Adhesive: If using a fabric glue, apply a thin, even layer of the adhesive to the back of the delaminated interlining. If using a fusible web, cut a piece of the web slightly larger than the damaged area and place it between the interlining and the main fabric.
  4. Press the Interlining: Use a warm iron to press the interlining firmly onto the main fabric. Follow the instructions on the adhesive for the appropriate temperature and pressure. Hold the iron in place for a few seconds to allow the adhesive to bond.
  5. Let it Dry: Allow the adhesive to dry completely according to the instructions. This may take several hours or overnight.
  6. Trim the Excess: Once the adhesive has dried, trim any excess interlining or adhesive from the edges of the repaired area.

Repairing Major Damage

For more significant damage, such as large areas of delamination or extensive wear and tear, you may need to replace the interlining. This is a more complex repair process that may require some sewing skills. Here's how you can do it:

  1. Remove the Damaged Interlining: Carefully cut away the damaged interlining from the main fabric using a sharp pair of scissors. Be careful not to cut through the main fabric.
  2. Measure and Cut the New Interlining: Measure the area where the interlining needs to be replaced and cut a piece of new interlining slightly larger than the measured area. Make sure to choose the same type of interlining as the original.
  3. Position the New Interlining: Place the new interlining on the wrong side of the main fabric, aligning it with the edges of the area where the old interlining was removed.
  4. Pin the Interlining: Use straight pins to secure the new interlining in place. Make sure the interlining is flat and smooth, without any wrinkles or bubbles.
  5. Sew the Interlining: Use a sewing machine or a hand needle to sew the new interlining to the main fabric. You can use a straight stitch or a zigzag stitch, depending on the type of fabric and the desired finish. Make sure to sew close to the edges of the interlining to ensure a secure bond.
  6. Trim the Excess: Once the interlining is sewn in place, trim any excess fabric from the edges of the repaired area.

Preventing Future Damage

To prevent future damage to your bonded interlining, it's important to take proper care of your garments. Here are some tips:

  1. Follow the Care Instructions: Always read and follow the care instructions on the garment label. Avoid washing or dry cleaning the garment in high temperatures or using harsh detergents.
  2. Handle with Care: When wearing or handling the garment, be gentle and avoid excessive bending, stretching, or rubbing. Pay special attention to areas with high stress, such as the elbows and knees.
  3. Store Properly: When not in use, store your garments in a cool, dry place. Avoid hanging them in direct sunlight or in a damp environment, as this can damage the interlining.
  4. Choose Quality Interlining: When purchasing garments, look for high-quality interlining that is durable and well-bonded. Avoid buying garments with poor-quality interlining or signs of weak bonding.
