What Is Interlining? Types, Benefits, and Applications Explained
In textile and footwear manufacturing, some materials work quietly in the background but make a big difference in the final product. One such material is interlining. It is not usually visible to the customer, yet it plays a key role in shaping and supporting garments, shoes, and bags.
This article explains what interlining is, its different types, and why manufacturers use it. It is useful for sourcing teams, designers, and production managers who want to understand how this material adds value to finished products.
What Is Interlining?
Interlining is a layer of fabric that sits between the outer fabric and the inner lining of a product. It is used to provide shape, structure, firmness, or extra support. In some cases, it can also add comfort or insulation.
Unlike outer fabrics that are chosen for appearance, interlining is chosen for function. It helps garments maintain their form, prevents stretching or sagging, and reinforces stress points like collars, cuffs, or shoe fronts.
Types of Interlining
Interlinings come in different forms. The two main types are fusible interlining and non-fusible interlining. Each has its purpose depending on the end use.
1. Fusible Interlining
Fusible interlining has a thin layer of glue on one side. When heat and pressure are applied, the glue melts and bonds the interlining to the outer fabric. This process is fast and suitable for mass production.
Common Uses:
- Dress shirts
- Suit collars and lapels
- Handbags
- Shoe uppers
Benefits:
- Clean and flat finish
- Easy to apply
- Strong hold and durability
2. Non-Fusible Interlining
Non-fusible interlining is sewn between fabric layers. It is often used when the fabric is sensitive to heat or when a softer structure is needed.
Common Uses:
- High-end custom garments
- Traditional tailoring
- Specialty shoes or leather products
Benefits:
- Retains natural drape of fabric
- More breathable
- Gentle on delicate fabrics

Why Is Interlining Important?
Interlining offers several benefits that directly affect the quality of your product. Here are some of the main reasons why manufacturers use interlining:
| Benefit | Why It Matters |
| Shape Retention | Keeps garments and shoes looking sharp and structured |
| Durability | Reinforces areas that experience wear and pressure |
| Comfort | Adds softness or cushioning where needed |
| Functionality | Offers water resistance, thermal insulation, or extra grip |
Without interlining, many products would lose their shape or wear out faster.
Where It Is Used?
Interlining is used in many different types of products. Some examples include:
- Clothing: Formal-wear, uniforms, shirts, jackets
- Footwear: Casual shoes, sports shoes, safety boots
- Accessories: Ladies’ handbags, wallets, belts
- Work-wear: Waterproof coats, insulated uniforms, protective clothing
From fashion to function, interlining supports the performance and look of the final product.
How to Choose the Right Interlining
The right choice depends on your fabric, product type, and production process. When selecting interlining, consider the following:
- Fabric Compatibility: Will it bond well with your fabric?
- Heat Resistance: Can your fabric handle heat if using fusible types?
- Required Structure: Do you need stiffness or softness?
- Usage Conditions: Will the product be washed or exposed to moisture?
If you’re unsure, it’s best to test samples or speak to a supplier who understands your production needs.

Interlining might be hidden, but its role is powerful. It shapes the look, feel, and lifespan of everything from shoes to suits. Whether you’re a large manufacturer or a small studio, using the right interlining can make your product stand out in both quality and durability.
