Fusible Interlining

Fusible interlining offers a time-saving and efficient solution. Featuring a heat-activated adhesive backing, it readily bonds to fabric upon application of pressure with an iron at the manufacturer’s recommended temperature settings. This eliminates the need for stitching, streamlining the interlining application process.

Advantages of Fusible Interlining

  • Effortless Application: Fusible interlining eliminates the requirement for needle and thread, making it ideal for projects requiring speed or where intricate stitching techniques are not desired.
  • Durable Bond: When applied correctly, the heat-activated adhesive creates a strong, long-lasting connection that withstands washing and wear. Studies published in the Journal of Textile Science and Apparel Technology [1] support this claim, demonstrating the stability of properly fused interlining even after multiple laundering cycles.

Applications for Fusible Interlining

  • Crisp Collars and Cuffs: Fusible interlining excels at creating sharp, defined edges for collars and cuffs, contributing to a professional aesthetic.
  • Structured Waistbands: Waistbands that maintain their shape and provide a flattering silhouette benefit significantly from the use of fusible interlining.
  • Defined Pockets: Structured and well-defined pockets become achievable with the ease and efficiency of fusible interlining application.

Non-Fusible Interlining

While not boasting the heat-activated convenience of its counterpart, non-fusible interlining offers distinct advantages. This type requires stitching to secure it to the fabric, allowing for greater control over placement and intricate shaping, particularly on curved seams.

Benefits of Non-Fusible Interlining

  • Adaptability: Non-fusible interlining comes in a broader range of weights and materials, catering to a wider variety of project requirements.
  • Reusability: Unlike its fused counterpart, non-fusible interlining can be unstitched and reused on another project if necessary, minimizing waste.
  • Heat-Sensitive Fabrics: For delicate fabrics that might be damaged by heat, non-fusible interlining offers a safe alternative to the fusing process.

When Non-Fusible Interlining Takes Center Stage

  • Curved Seams: Stitching non-fusible interlining allows for precise application and smooth results on curved seams.
  • Knit Fabrics: The flexibility of non-fusible interlining works well with knit fabrics, providing essential structure without compromising their inherent drape.
  • Heavy Fabrics: For thicker fabrics requiring heavyweight interlining, stitching offers a more secure bond compared to the adhesive properties of fusible options.

Selecting the Optimal Interlining

The optimal interlining choice hinges on the specific project and fabric characteristics. Here’s a breakdown of key considerations:

  • Fabric Type: Is the fabric heat-sensitive? Does it require intricate shaping techniques? These factors will influence your selection.
  • Garment Style: A structured jacket might necessitate a different interlining type compared to a flowy dress.
  • Desired Outcome: Do you prioritize a fast and easy application or require more control over placement for intricate details?

Pre-Application Testing

Before committing to large-scale application, always test a scrap of interlining on your fabric. This allows you to assess the adhesion (for fusible options), drape, and overall compatibility with your chosen materials.


Understanding the distinct characteristics of fusible and non-fusible interlining empowers you to make informed decisions for your sewing projects. By carefully considering the application method, fabric type, and desired outcome, you can select the interlining that elevates your creations to a professional standard.

Fusible Interlining Non Woven Interlining

Paper Fusion and Its Process.

What is Paper Fusion

Paper Fusion is also known as Non- Woven Fusible interlining. It is a material that will melt when heated. 


The woven kind is a cotton fabric with one side primed with fusible glue. The non-woven kind consists of agglutinated and compressed fibers and one side is primed with fusible glue.


Non-Woven Fusible Interlining fabrics are mainly used as a raw material in the sewing process and used in cuffs and collars of shirts.


As the name suggests it is a non-woven interlining but more like sheets of paper or cardboard. This type of material is used for bags and purses. 


It is made directly from fiber to fabric stage in the process reducing the cost of the base fabric. As there is no yarn used in producing nonwovens, it lacks the strength needed for garment use and there are many methods applied to present required power to nonwoven textiles, called Bonding.


Polyester fabrics commonly do not stain simply and are resistant to stretching or shrinking. Polyester linings are usually used for lining and insulating coats and hats but may be used for any other type of lining job. This lining polyester is equipped with a nice sheen and shows to be a part transparent.


Fusing Paper Process

To use paper fusion, the first step is to place the resin side of the fusing on the backside of the fabric and heat it with an iron. When placed on the fabric the melting action causes the interlining to stick to the fiber. 


The paper fusion is not woven or knitted, It is used to make fabrics stiffer and especially effective for mending hems and small holes. 


There are various qualities of paper fusing to meet the needs of different products. A shi collar would require thick fusing whereas, for a woman’s dress neckline, one would have to use thin fusing paper. Paper fusing can also be used in belt rolls, the lower part of salwar, bags, and much more. 


Selecting premium quality paper fusing is highly essential to create a well-constructed garment. Using the wrong type of paper fusing could make the garment odd-looking and would fail to provide support.

Fusible Interlining

What is Fusible Interlining Fabric

When you hear the term, “Interlining Fabric” you might be confused about what exactly it would mean. Let’s understand in simpler terms, Interlinings are the accessories used between two layers of fabric to keep the different components of apparel in the desired shape or to improve the aesthetics and/or performance.

Now let’s understand What is Fusible Interlining Fabric.

The concept of transforming the old cloth into new is something that we all have heard of, similarly, Fusible Interlining is used in a lot of garments and curtains as well.

What is Non-Fusible Interlining 

Non-fusible interlining is an extra layer embedded between the outer fabric and the regular lining of a garment without chemical bonding. 

These followings are the primary target of utilizing interlining in garments –

  • Interlinings are primarily utilized for giving quality, security, and shape maintenance.
  • At the period when melded to the external shell fabric, it goes about as a composite. Thus levels out the outer case against any distortion under load
  • Improves pure and hand feel of fused laminate
  • Contains the state of the united part throughout use and aftercare treatment
  • Improves the life span of the melded part

Different Types of Fusible Interlining.

  •  Woven interlining

 It was mainly 100% cotton fabrics made stiff by starch application and was non-fusible. However, the unpleasant hard touch and irregular points during washing led to the development of woven fusible interlinings. It is most often used by designers to avoid wastage.

  • Waterproof Fusible Interlining

As the name suggests the material used is waterproof and the material made from it can easily be water-resistant. 

  • Decorative Fusible Interlining

This is often used for adding badges, patches, and can also be used to discreetly hide a hole while making your wardrobe more stylish

  • Double-sided Fusible Interlining

Double-sided fusible interlining is used to get rid of holes in clothing, especially jeans.

It’s very easy to use as both sides of the material can be used in this method. 

How Do You Use Fusible Interlining Fabric?

Fusible Interlining is very smooth to use as long as you choose the right type. Now let’s understand how to apply in by the following steps, 

  • The first step is to mark out from the size that you want leaving out some extra space if you are repairing any hole. 
  •  Mark the area that you need and place the fusible interlining wherever you want it. 
  • The fusible interlining would act as a glue right here. Use a heated object or an iron to make the glue melt, so that the interlining sticks to the fabric.
  • Place your iron on each part for 30-40seconds before any movement. 
  • Leave it for sometimes all the fabric has got stuck in the right way. To avoid glue on the iron board make sure you place cotton underneath.

The Different Types of Fusible Interlining

The Different Types Of Fusible Interlining

In garments and apparel manufacturing industries, fusible interlining is a very common technique. It is a type of interlining which attaches the garment components through heat and pressure for a certain amount of time. It is a useful technique for manufacturing curtains, clothes, upholstery, etc.

The technique is essential for binding the textile components and making the material resistant to stretching. By using the method, you can give the cloth more thickness. 

Diverse categories

The basic process of carrying out the fusible interlining process is by the application of thermoplastic adhesive resin. Here, a base fabric is on one side, and the other side has another kind of fabric that gets attached into a single and thick cloth piece. It requires the adhesive that suits the textile’s nature and external heat and pressure to bind into one unit ultimately. However, there are different types of fusion interlining processes available with multiple textile types and kind of projects. It is better to have an idea of the types before getting started with it.

  • Non-woven fusible interlining

Non-woven fusible interlinings are a great option for those in the manufacturing of bags, purses and similar things. Here the interlining is not for any woven fabric; instead, they use a stiff sheet, usually made of paper or cupboards. They help bring rigidity to the base, and thus they are highly suitable for reinforcing at the bottom of the bags. Bags having non-woven fusible interlining are well resistant to rough handling for the stiffness of the materials in use.

  • Woven fusible interlining

As the name suggests, the binding takes place between actual woven fabric materials. Here, a light weighed fabric gets interlined, which presents a finishing touch to clothes and apparels. For being lightweight, it is very easy to get reinforced with other fabrics. It provides a flexible texture to the fused unit and is better with the most demanding conditions. Ideal for waistbands, outerwear jackets and similar items.

  • Water-resistant fusible interlining

Water-resistant or waterproof fusible interlining is a method where the fabric in use is impermeable to incoming water. For making any item or material resistant to water, it is better to apply the fusible interlining technique with the help of waterproof coatings. It brings good rigidity and stiffness to the manufactured products. Ideal for rainwear pieces of clothing like raincoats, rain jackets, etc. In the process, it requires thermal bonding of the non-woven material to get fused, for which they are well resistant to chemical washing, bleaching and other harsh processes. 

  • Knitted fusible interlining

Knitted fusible interlinings are best for efficient production units. For providing stretchability to knotted garments, this method is ideal. They have better recovery properties for the advantage of being stretchable. For that, manufacturers who manufacture jerseys, coats, blazers and other high valued garments use it. The lightweight and soft texture of the laminate are best for the mentioned garments. Knitted types have variations in looping structures that provide flexibility and stables with the material in use. 

Other types

The methods mentioned above are the main variants of the fusible interlining. The following are other types that fall under the subcategories of the formerly mentioned kinds.

  • Quilted Fusible Interlining: You can quilt two pieces of cloth without adding foam or pad in this type. No need to sew it as you only need to fuse the interlining at the end. It helps when you do not have a warm material like fleece or flannel, you can serve the purpose by interlining to quilt the clothing.
  • Decorative Fusible Interlining: Mainly for adding the patchy look on the clothes for designing purpose. You can also use it to cover holes of a clothing piece, giving a stylish outlook.
  • Double-Sided Fusible Interlining: Ideal for repairing holes in clothes, especially in jeans. Bonds both the sides like double-sided tape, making it easy to use.

Do it right

To carry out the fusing process perfectly, you need a well-working fusing press and the correct fabric to use. Identify the right process as per your manufacturing requirements.


Check factors like dwelling time, temperature conditions, adhesive quality, bond strength and other relevant conditions that play a part in the interlining process. Reading the above will surely help you gain an overall knowledge of the types of fusible interlinings.
