Non-woven interlining plays a pivotal role in the world of fashion and garment construction, yet its intricacies are often overlooked. This article aims to demystify non-woven interlining by exploring its various types, weights, and applications. Whether you’re a seasoned seamstress or a budding fashion designer, understanding the nuances of non-woven interlining can take your creations to the next level.

Types of Non-Woven Interlining

  • Fusible Interlining: This type of interlining has adhesive on one side, which is activated by heat. It is commonly used to add structure and stability to fabrics without the need for stitching.
  • Non-Fusible Interlining: Unlike fusible interlining, non-fusible interlining needs to be stitched or attached using other methods. It is often used in areas where fusible interlining may not be suitable.
  • Thermal-Bonded Interlining: This type of interlining is bonded using heat, which creates a strong and durable bond. It is ideal for garments that require extra reinforcement.
  • Chemical-Bonded Interlining: Chemicals are used to bond the fibers together in this type of interlining. It is known for its excellent drapability and softness.
  • Stitch-Bonded Interlining: Stitching is used to bond the fibers together in this type of interlining, providing flexibility and strength. It is often used in areas that require extra durability.

Weights of Non-Woven Interlining

Non-woven interlining is available in different weights, measured in grams per square meter (gsm). The weight of the interlining you choose will depend on the fabric and the desired effect:

  • Lightweight (20-50 gsm): Ideal for lightweight fabrics and delicate garments, providing subtle support and structure.
  • Medium-weight (50-100 gsm): Suitable for a wide range of fabrics and garment types, offering a balance of support and flexibility.
  • Heavyweight (100+ gsm): Used for adding significant structure and support to garments, making them more durable and rigid.

Applications of Non-Woven Interlining

Non-woven interlining has a multitude of applications in garment construction, including:

  • Collars: Adding structure and shape to collars, ensuring they stand upright and maintain their form.
  • Cuffs: Providing stability and durability to cuffs, preventing them from losing their shape over time.
  • Waistbands: Ensuring waistbands maintain their shape and structure, providing a comfortable fit.
  • Front Plackets: Reinforcing the front plackets of shirts and blouses, making them more durable and resistant to wear.

Choosing the Right Non-Woven Interlining

When selecting the right non-woven interlining for your project, consider the following factors:

  • Fabric Type: The weight and texture of the fabric will influence the type of interlining you need. For example, lightweight fabrics may require a lighter interlining, while heavier fabrics may need a heavier interlining for support.
  • Garment Style: Different garments require different levels of structure and support. For example, a structured jacket may require a heavier interlining, while a lightweight blouse may only need a light interlining for reinforcement.
  • Desired Outcome: Consider the final look and feel you want to achieve with your garment. A heavier interlining will provide more structure and rigidity, while a lighter interlining will offer more flexibility and drape.

Care and Maintenance of Garments with Non-Woven Interlining

To ensure the longevity of garments with non-woven interlining, follow these care instructions:

  • Washing: Use a gentle cycle and mild detergent to wash garments with interlining, and avoid using bleach or harsh chemicals that can damage the interlining.
  • Drying: Air dry or use a low heat setting in the dryer to avoid damaging the interlining, and avoid hanging garments with interlining in direct sunlight, as this can cause fading.
  • Ironing: Use a low to medium heat setting and a pressing cloth to iron garments with interlining, and avoid ironing directly on the interlining to prevent damage.


Non-woven interlining is a versatile and essential component in garment making, providing structure, support, and durability to a wide range of fabrics. By understanding the types, weights, and applications of non-woven interlining, you can choose the right one for your projects and ensure your garments look and feel their best. Whether you’re adding a touch of structure to a collar or reinforcing a waistband, non-woven interlining is a valuable tool that can elevate your sewing projects to new heights.
