What Is Knitted Interlining Used For?

Knitted interlining has become more and more common in today’s garment industry. As clothing styles move toward comfort, flexibility, and lightweight designs, traditional stiff interlining is no longer suitable for every product. It offers support while allowing garments to move naturally with the body. In this article, we’ll take a closer look at how knitted-interlining works, where it’s used, and why many factories prefer it.

What Is Knitted Interlining?

It is made using a knitting structure instead of a weaving structure.
This gives the fabric a softer feel and a certain level of stretch, which helps it work well with flexible outer fabrics.

Most knit interlining is made from polyester yarn and supplied as fusible interlining, with adhesive applied evenly on one side. When fused correctly, it bonds well without changing the natural drape of the garment.

How Does the Knitted Structure Affect Performance?

Natural Stretch

The knitted structure allows the interlining to stretch slightly and return to shape. This reduces pulling and tension in the garment.

Better Fabric Movement

When the outer fabric bends or stretches, the interlining moves with it instead of resisting it.

Improved Wearing Comfort

Garments feel less tight and more relaxed, especially during daily movement.

Knitted Interlining vs Woven Interlining

It feels softer and lighter, while woven interlining usually feels firmer.

Appearance

Garments with look more natural and less rigid.

Stretch Compatibility

It matches stretch fabrics better, reducing distortion.

Garment Style

It suits casual and fashion garments, while woven interlining is better for structured styles.
