Interlock Knit Fabric


Interlock Knit Fabric is stretchy fabric knitted with interlocking stitches by alternating sets of needles on a circular knitting machine.
Instead of creating ridges of knit and purl stitches, interlock knit fabric has two rows of stitches, one directly behind the other. Interlock is a very elastic knit with similar right and wrong sides.


Interlock Knit Fabric is used in all sorts of elastic garments, such as t-shirts, tops and sportswear. It is relatively simple to use, but be careful not to stretch the fabric while sewing. Interlock Knit Fabrics are usually used for the production of t-shirts, polos and dresses. An expensive knit top will most likely would be sewed from a interlock knit fabric and an everyday t-shirt will probably be jersey.

More About Interlock Knit Fabrics:

Interlock Knit Fabrics are variations of rib knit fabrics. The front and back of interlock knit fabrics are the same. These fabrics are usually heavier and thicker than regular rib knit fabrics unless used with finer yarns. The interlocking of stitches prevents runs and produces apparel fabrics that do not ravel or curl at the edges.

General term for Interlock Knit fabrics from fine to heavier weights including single, double and interlock jerseys. Interlock Knit Fabrics are stretchy and crease resistant.

Interlock Knit Fabric is a variation on rib knit fabrics. Instead of creating ridges of knit and purl stitches, interlock has two rows of stitches, one directly behind the other. This can create the impression that the fabric is comprised of two layers, which is why it is sometimes categorized as a double-knit fabric. (The two layers of interlock knit fabric, however, can’t actually be separated.) Interlock knit fabric is thicker than jersey, and both sides of the fabric are smooth, like the right side of a jersey fabric. Interlock is more stable than jersey, which means it doesn’t stretch out of shape as easily as jersey and it doesn’t curl at the edges. This ability to lie flat, as well as the fact that interlock take prints nicely, makes it popular for industrial sewing.

The face of the Interlock Knit fabric looks more or less the same because they all have small vertical ribs. When you go to the back of the fabric and gently pull across the direction of stretch, the Interlock knit fabric will look more or less the same on the face and back. The jersey has a wavy pearl pattern that runs perpendicular to the face rib. If you're still not certain, you can cut a piece from selvedge to selvedge, if the fabric is jersey the cut edge will curl on itself, interlock knit fabric will lay more flat.

Interlock knit fabric has the technical face of plain fabric on both sides, but its smooth surface cannot be stretched out to reveal the reverse meshed loop wales because the wales on each side are exactly opposite to each other and are locked together. Each interlock knit fabric pattern row requires two feeder courses, each with a separate yarn that knits on separate alternate needles, producing two half-gauge 1 x 1 rib courses whose sinker loops cross over each other.

If the needle heads are facing with each other, it is called interlock gating or interlock knit fabric.

Interlock knit fabrics are mainly produced on specially designed circular double jersey machines called interlock knit machines.

Interlock Knit Fabrics are high speed, multi-feeders with closed cam track machines.

The common gauges for interlock fabrics are 20-24 npi, using 1/30 Ne cotton or 1/48 Nm worsted yarns.

Interlock Knit Fabric is a special type of eight-lock knit cloth. The stitch variation of the rib stitch, which generally resembles a double 1 x 1 ribbed fabric that is interknitted with crossed sinker wales. Plain (double knit) interlock knit fabrics are thicker, heavier, and more stable than single knit constructions. The fabric has a smooth surface on both sides, and possesses good wearing qualities.
