ribknit

Ribknit is a fabric and stitch pattern used in knitting that is created by alternating knit and purl stitches across the same row. The result is vertical ridges, or ribs, that run along the fabric. The most common forms are 1x1 rib (K1, P1) and 2x2 rib (K2, P2), though other widths can be used by varying the number of knit and purl stitches in a sequence.

The structure of ribknit gives it high elasticity and good recovery, making it particularly suited for edges that need to stretch and hold their shape. Because of its elasticity, ribknit is commonly used for hems, cuffs, and waistbands, as well as for entire garments such as sweaters and hats.

Ribknit fabrics can be produced as flat knit textiles or as tubular fabrics on circular machines, which enables seamless edges and cuff sections. In hand knitting, rib patterns are typically worked flat or in the round, with the ribs continuing across the project.

Variations beyond the basic 1x1 and 2x2 include wider rib patterns (for example, 3x3 or 4x4), which create a denser texture and a different visual effect, while maintaining the same basic knit-purl principle. Fibers and yarn weights influence the hand, drape, and warmth of ribknit fabrics.

Care considerations depend on fiber content. Wool and wool blends may require gentle washing and blocking to maintain shape, while cotton and synthetic ribknits can be more dimensionally stable but may still shrink or stretch with washing.
