Interlock (double knit) fabric

Single jersey is knitted on one needle bed, while interlock is knitted on two, which gives a thicker, firmer fabric that looks the same on both sides. Jersey has V-stitches on the face and a different back, stretches more and curls at the edges. Interlock lies flat when cut, looks smooth on both sides and distorts less.

With the same yarn, interlock is usually heavier and more opaque. Choose jersey for lightness and stretch, interlock for stability and a clean look on both sides.

No, they are different structures, although both are made on machines with two needle beds. Rib has visible vertical ridges and high stretch across the width. Interlock is made of two 1x1 ribs knitted into each other, so it has a smooth face on both sides, no visible ribs and less stretch, with a more stable and fuller feel.

They are confused because interlock looks like a stretched rib. Pull a rib and you see the ridges, pull interlock and you do not. Rib suits pieces that must hug the body, interlock suits pieces that must keep their shape.

Interlock is a double knit made of two 1x1 ribs knitted into each other so that the stitches on both faces sit exactly behind one another. That is why the fabric looks the same on both sides, smooth and fine. It is made on circular machines with a cylinder and a dial, using long and short needles working alternately.

Being thicker and more compact than jersey, interlock does not curl, cuts cleanly and keeps its shape. It is used for quality t-shirts, children's wear, uniforms and pieces where you want no see-through and little distortion.

Not exactly. Interlock is one type of double knit, but "double knit" is a broader term for any knit made on two needle beds with a smooth look on both faces: interlock, ponte, milano, scuba and others. What separates them is the stitch pattern, the yarn and the density.

In international offers "double knit" often just means a fabric that is thicker and more stable than jersey. To avoid surprises, always ask for the exact structure, the weight and a swatch rather than only the trade name.

Double-face is a double knit with two different faces, for example two colours, two textures or two yarns, visible on both sides. It is made on machines with two needle beds, controlling which yarn shows on each face. It can be reversible, so the garment can be worn either way.

Because it is made of two layers linked together, the fabric is thicker, more stable and curls very little. It is used for light jackets, sweatshirts and pieces worn on both sides. It costs more than a jersey because it uses more yarn.

A jacquard knit has the pattern built directly into the structure, not printed, by selecting individually the needles that form each stitch. It is made on circular jacquard machines with one or two needle beds. With two beds, the fabric is thicker and more stable and can carry several colours.

The pattern repeat is limited by the machine and by the number of colours. It is used for geometric designs, stripes and textures. The cost is higher than jersey, and an order usually requires an approved design.
