What Is the Function of Interlining Fabric in Garment Production?

In garment production and clothing manufacturing, interlining fabric, often called stiff fabric or hard fabric, plays a key role even though it’s hidden inside the garment. Without interlining, many clothes would look floppy, lose their shape, and feel less polished.

So, what exactly does interlining do in garment production? Let’s break it down.

What Is Interlining Fabric?

Interlining is an extra layer of fabric placed between the main fabric and the lining, or attached directly to specific parts of a garment. Its main purpose is to provide structure, support, and shape.

In garment factories and small-scale production, interlining is commonly used in areas that need extra firmness.

Functions of Interlining Fabric in Garment Production

1. Adds Structure and Shape

Interlining helps garments look more neat and structured, especially on:

• Shirt collars

• Cuffs

• Button plackets

• Waistbands on skirts or trousers

Without interlining, these parts can easily collapse or wrinkle.

2. Improves Durability

By adding an inner support layer, interlining makes garments more durable and long-lasting. The fabric holds its form better, even after frequent washing and daily wear.

This is especially important in garment production where consistent quality matters.

3. Creates a More Professional Look

Interlining helps maintain the intended silhouette of the design. The final piece looks cleaner, sharper, and more professional, perfect for formal or workwear collections.

4. Enhances Comfort When Worn

Even though it’s often called “stiff fabric,” the right interlining actually makes clothes more comfortable to wear. It keeps the main fabric from shifting, sagging, or losing shape.

5. Supports Different Design Needs

Interlining comes in different types and thicknesses. In garment production, it’s chosen based on:

• The main fabric

• The garment design

• The target market

Formal wear usually needs firmer interlining, while casual pieces work better with softer options.

Common Types of Interlining Fabric

Some interlining fabrics commonly used in garment production include:

• Woven interlining

• Non-woven interlining

• Fusible interlining (with adhesive)

• Sew-in interlining

Each type gives a different result, so choosing the right one really matters.

Final Thoughts

Interlining fabric might be invisible from the outside, but it has a huge impact on garment quality. It helps shape the design, improves durability, and gives clothes a clean, well-made finish.

If you want your garments to look polished and professional, choosing the right interlining is just as important as choosing the main fabric.
