What is a Rib Knit Fabric?

You can identify a rib knit cloth by its distinctive loop patterns, common with many knitted fabric types. Sometimes, it’s called Ribana fabric, and other times, it’s called sweater knit fabric.

Like other varieties of knitted fabric, such as the interlock stitch knit or the raschel knit, etc., they can be made from natural fibers like cotton or synthetic ones like rayon or polyester.

Raised vertical ribs are also prominent in rib knit fabric. However, in this case, they are worked into the fabric in the other direction using purl stitches and knit stitches in an alternating pattern. 

Understanding What Rib-knit Fabric Is

Rib Knit Fabric

Rib knit fabric is a type of knitted fabric characterized by vertical rows of knit stitches that alternate between high and low. They are more durable and stretchy than jersey knits and have a more tailored cut.

Generally speaking, you can think of Rib Knit Fabrics as a form of double-sided fabric with noticeable, perpendicular ribs on both sides. This quality makes them perfect for uses where you need both sides of the fabric to appear the same.

Rib knits are frequently misunderstood as ribbing fabric. Still, they are not the same kinds of textiles. In addition to the usual applications of cuffs, waistbands, and neckbands, rib knits can be used to construct entire outfits and sometimes haute couture fabrics.

However, ribbing fabric is a foundation (a tight sort of rib knit) that is designed solely for use as a collar, sleeve cuff, or waistline.

One can choose between the more common 1×1 rib knit or the more complex 2×2 rib knit. The 1 x 1 pattern consists of one knit and one purl stitch, whereas the 2 x 3 pattern consists of two knits and three purls.

Stretchy rib knits stay smooth and wrinkle-free. The fabric’s elasticity makes it quick to recover its original shape after being stretched. That’s why you’ll find them so often on the edges of socks, sleeves, waists, and necklines of t-shirts. Sweaters and women’s outfits also have them.

Production Process of Rib Knit Fabric

Rib knit fabric is produced with two needles to generate the vertical ridges that characterize the fabric. A specific number of knit stitches (smaller and less noticeable) and purl stitches (larger and more noticeable, forming the groove between the ribs) are worked in multiples of the span of the fabric.

This fabric is usually made and sold in circular pieces, without any selvage to make the vertical ribs.

In the process of producing this fabric, a 1 x 1 rib, known as a plain rib, a type of rib stitch often used in knitting in which the right and back sides of each wale alternate across plain and purl stitches, is sometimes constructed. 

A 2 x 2 rib, also known as Swiss rib, produced by knitting plain stitches on the front of the fabric and purling them on the back of the fabric alternately every two rows, may also be constructed alongside a  6 x 2 rib. 

The 6 x 2 rib fabric is produced when six right-side wales of plain stitches are alternated with two back-side wales of purl stitches.

To create a ribbed knit, the knitter works with multiple knit stitches, then a series of purl stitches, and so on, until the row is complete. The knitter then turns the work inside out to make a ribbed design.

Ribbing is commonly employed at the corners of clothing, notably socks, to ensure a secure fit and maintain the garment’s intended form. For example, the entire knit fabric of a sweater can stretch to fit a wide range of sizes.

Rib Knit Fabric Over The Years. A Brief History

Knitting developed as a global trade during the era of European discovery and colonization, transiting from one country to the next through explorers and colonists.
