Stitch Bonding Explained: How It Works and Its Three Main Variants

October 3, 2026

Stitch bonding is a way of making fabric by pushing a row of needles through a fibre web or through stacked yarn layers and locking the material together with warp-knitted loops. The three variants you will meet in practice are Maliwatt (a web stitched with yarn), Malivlies (a web stitched with its own fibres, no yarn at all) and Malimo (warp-like and weft-like yarn layers stitched to each other).

Most of what ranks for this term is either a patent PDF or a slide deck behind a login, and at least one fabric-trading page describes Malivlies as a scrim-reinforced product, which is not what the patent literature says. This page sets the three variants side by side so you can tell which one a supplier, a sample or a spec sheet is really talking about.

How the stitch bonding process works

The starting material is not a finished fabric. It is a loose web of fibres, one or more sheets of parallel yarns, or a flat substrate that needs reinforcing. On its own it has little or no strength across the width.

A bar of needles penetrates that material across the full working width at once. Each needle draws a loop through to the other side and knits it into the loop from the previous stroke, exactly as a warp knitting machine builds a wale. The result is a set of parallel stitch lines running down the length of the fabric, which is why a stitch-bonded cloth looks like a knit on the face even though the body of it is nonwoven.

Two points follow from that mechanism, and they explain most of what buyers notice on the finished roll:

• The fabric is a hybrid. The web or yarn layer gives the bulk and cover; the loop system gives the strength and holds the shape.
• There is no chemical binder and no thermal bonding step in the basic process. The consolidation is purely mechanical, done by the loops.

The technology dates from the 1950s in the former East Germany, where it was developed under the Malimo name. That is why the variant names all start with “Mali”, and why people still say “Malimo” when they mean stitch bonding in general.

The knitting elements that do the work

In the Maliwatt arrangement the stitching is done by a compound needle working with a closing wire. The needle is set horizontally. It pierces the fibre layer, takes one or two stitching yarns, and the closing wire shuts the hook so the yarn can be pulled back through the web without snagging fibres on the way out.

This is the detail people coming from tricot or raschel machines tend to miss: the needle has to get through a thick, uneven substrate on every stroke, not just through an open loop. The condition of the needle and the closing wire therefore shows up directly in the stitch line. If you are sourcing these elements, our parts pages cover the compound needle for stitch bonding and the closing wire for stitch bonding.

The substrate fed to a Maliwatt machine is normally a cross-laid web, so the fibres lie mostly across the width and the stitch lines run down the length. The two directions reinforce each other.

Maliwatt, Malivlies and Malimo compared

The quickest way to separate the three is to ask two questions: what goes into the machine, and what forms the loop.

Maliwatt reinforces a web with yarn. Because the loops are made from a dedicated yarn, the strength along the length comes largely from that yarn and can be chosen independently of the fibre in the web.

Malivlies uses no yarn. The needles pull fibres out of the web and knit those fibres into loops, so the fabric is one material all the way through. One line to remember: Maliwatt uses yarn, Malivlies does not.

Malimo in the narrow sense is not a web process. It takes yarn sheets, places the warp-like layer over the weft-like layer, and overstitches them. The same stitching principle was later extended to nonwoven substrates, which is how the family of web-based variants came about.

For the machine side of each variant we have separate pages: the Maliwatt stitch bonding machine, the Malivlies stitch bonding machine and the Malimo stitch bonding machine.

Which variant fits which job

Use the rules below as a first filter. Each one is written to stand on its own.

• If you want a single-material fabric with no yarn to buy, stock or thread, then Malivlies is the variant to look at. This does not apply if the end use depends on lengthwise strength that the web fibres alone cannot give.
• If you need the stitch line to carry load, or you want to choose the reinforcing material separately from the web fibre, then Maliwatt is the variant to look at. This does not apply if a yarn-free, single-material product is a requirement of your customer.
• If your input is yarn rather than fibre, and you want straight yarn layers held together instead of interlaced, then Malimo is the variant to look at. This does not apply to web-based nonwoven products; those belong to the two variants above.

If a quotation or a sample card just says “stitch bonded”, ask which of the three it is before comparing prices or strengths. The word covers fabrics with and without stitching yarn, and they do not behave the same.

Where stitch-bonded fabrics are used

The end uses reported for web-based stitch-bonded fabrics include furniture fabrics, blankets, cleaning cloths, composites and geotextiles, with automotive interiors, medical products and insulation also mentioned. For Malimo yarn-layer fabrics the listed applications are aerospace, wind turbine blade manufacturing, thermal insulation fabrics and apparel.

The pattern behind that list is simple. Web-based variants go where bulk, cover and low cost per square metre matter. Yarn-layer fabrics go where straight, uncrimped reinforcement matters, which is why they turn up in composite work.

What this page does not cover

Working width, gauge and the other machine parameters are a separate decision from choosing the process, and they depend on the product you are making. We deal with them in stitch bonding machine width and gauge, and the machine range itself is on the stitch bonding machine page. For the full Grand Star equipment catalogue, see grandstarcn.com.

If you already know the substrate you want to run and the end use, send us those two details and we can tell you which variant the job calls for before any machine is specified.

Frequently Asked Questions

What is stitch bonding in simple terms?

It is a mechanical way of turning a loose fibre web or stacked yarn sheets into fabric. Needles go through the material and knit rows of loops that hold everything together, so the cloth looks knitted on the face although its body is nonwoven.

What is the difference between Maliwatt and Malivlies?

Maliwatt draws a separate stitching yarn through the fibre web. Malivlies has no yarn: the needles pull fibres out of the web and form the loops from those fibres, giving a single-material fabric.

Is Malimo the same thing as stitch bonding?

The names are often used interchangeably because the technology was developed under the Malimo name in the 1950s. Strictly, Malimo is the variant that overstitches warp-like and weft-like yarn layers, while the web-based variants are called Maliwatt and Malivlies.

Is stitch bonded fabric woven or nonwoven?

It is classed as a nonwoven, because nothing is interlaced on a loom. It is better described as a hybrid: a nonwoven base reinforced and held in shape by knitted loops that pass through it.

What needles does a stitch bonding machine use?

In the Maliwatt arrangement a horizontally mounted compound needle works together with a closing wire. The pair pierces the fibre layer and pulls one or two stitching yarns back through it.
