How Does Knitted Interlining Work in Clothing?

What Is Knitted Interlining and Why Is It Widely Used in Modern Garments?

What Is Knitted Interlining?

Knitted interlining is a type of interlining made from knitted base fabric. Compared with woven or nonwoven interlining, its biggest feature is stretch and flexibility.

Because the base fabric is knitted, this interlining can move with the garment. It provides support without making the fabric feel stiff, which is why it is widely used in modern clothing, especially garments that focus on comfort and fit.

Main Characteristics of Knitted Interlining

Knitted interlining is popular mainly because of the following practical features:

  • Good elasticity and recovery

  • Soft hand feel

  • Better comfort when worn

  • Adapts well to stretch fabrics

  • Less restriction on garment movement

For garments that need both shape and flexibility, knitted interlining is often the preferred option.

Common Types of Knitted Interlining

Knit interlining can be classified based on knitting structure and construction.

Warp Knit Interlining

Warp knit interlining is produced using warp knitting machines.

Features:

  • Stable structure

  • Smooth surface

  • Controlled stretch

Typical Uses:

  • Jackets

  • Blazers

  • Fashion outerwear

Weft Knit Interlining

Weft knit interlining is knitted horizontally, similar to jersey fabric.

Features:

  • Higher elasticity

  • Softer feel

  • Better drape

Typical Uses:

  • Casual wear

  • Knit garments

  • Comfort-focused clothing

Circular Knit Interlining

This type is produced on circular knitting machines.

Features:

  • Uniform elasticity

  • Lightweight structure

  • Comfortable performance

  • Soft fashion items

Fusible Knitted Interlining

Most knit interlining used today is fusible, meaning it has a heat-activated adhesive coating.

Common coating materials include:

  • PA (Polyamide)

  • PES (Polyester)

  • EVA

The adhesive layer allows the interlining to bond firmly with the outer fabric while maintaining elasticity.

Where Is Knit Interlining Commonly Used?

Knit interlining is widely applied in garment parts that require flexibility:

  • Front panels of jackets

  • Lapels

  • Collars and cuffs (for stretch garments)

  • Waist areas

  • Knit fashion garments

It is especially suitable for stretch fabrics, knit fabrics, and modern slim-fit designs.

How to Choose the Right Knit Interlining

When selecting knit interlining, buyers usually focus on these points:

  • Match elasticity with the outer fabric

  • Choose the right thickness for garment weight

  • Check bonding performance after washing

  • Test shrinkage and recovery

  • Avoid over-stiff interlining for stretch garments

Sampling and fabric matching are strongly recommended before bulk production.

Why Knit Interlining Is Becoming More Popular

As garment trends move toward comfort, stretch, and casual styles, knit interlining fits modern market demand very well. It supports the garment shape while keeping the wearing experience natural.

That’s why many brands now replace woven interlining with knit interlining for specific designs.
