What Is Bonded Interlining and How Is It Used in Garments?

What Is Bonded Interlining?

Bond interlining is a type of interlining made by bonding fibers together through chemical or thermal processes, rather than weaving or knitting yarns.
Because of this structure, bonded interlining belongs to the nonwoven interlining family.

Its main purpose is to provide support, stability, and shape control for garments while keeping production efficient and cost under control.

How Bonded Interlining Is Made

Bond interlining is produced by forming a fiber web first, then bonding the fibers together. The bonding method determines performance.

  • Chemical bonding: fibers are bonded using resin

  • Thermal bonding: fibers are bonded using heat

Each method results in different hand feel, strength, and application suitability.

Main Types of Bonded Interlining

Chemical Bonded Interlining

Chemical bond interlining uses adhesive resin to fix fibers together.

Features:

  • Stable structure

  • Controlled stiffness

  • Good surface smoothness

Typical Uses:

  • Shirt components

  • Light to medium-weight garments

  • Fashion apparel requiring clean shape

Thermal Bonded Interlining

Thermal bond interlining relies on heat-melting fibers to bond the web.

Features:

  • More uniform bonding

  • Cleaner production process

  • Softer and more flexible feel

Typical Uses:

  • Casual garments

  • Knit garments

  • Comfort-focused clothing

Fusible Bond Interlining

Most bond interlining used today is fusible, meaning a heat-activated adhesive coating is applied on one side.

Common coating materials include:

  • PA (Polyamide)

  • PES (Polyester)

  • EVA

The coating allows fast bonding with outer fabrics during garment production.

Key Characteristics of Bond Interlining

Bonded interlining is widely used because it offers a practical balance between performance and cost:

  • Consistent thickness

  • Easy cutting and handling

  • Good bonding stability

  • Suitable for mass production

  • Reliable shape support

Where Is Bond Interlining Commonly Used?

Bond interlining is suitable for many garment parts:

  • Shirt collars and cuffs

  • Plackets

  • Front panels

  • Waist areas

  • Light jackets and blouses

It works well in applications where uniform support is more important than elasticity.

Bonded Interlining vs Woven and Knitted Interlining

Cost Lower Higher Medium
Elasticity Low Low High
Production Efficiency High Medium Medium

How to Choose the Right Bond Interlining

When selecting bonded interlining, buyers usually consider:

  • Garment fabric weight

  • Required stiffness level

  • Fusing temperature compatibility

  • Washing and durability requirements

  • Cost and production scale

Sampling and wash testing are strongly recommended before bulk orders.

FAQ

Is bond interlining the same as nonwoven interlining?
Bonded interlining is a major category within nonwoven interlining.

Does bond interlining shrink after washing?
Quality bonded interlining is pre-stabilized and shows minimal shrinkage.

Is bond interlining suitable for stretch fabrics?
Generally not. Knitted or elastic interlining is better for stretch garments.

Can bond interlining be customized?
Yes. Weight, thickness, coating type, and width can be adjusted.

Is bond interlining suitable for high-speed garment production?
Yes. It is widely used in industrial garment manufacturing.
