Interlock Knit Fabric – Another Double Knit Family Fabric

Interlock knit fabric is a type of double knit. Interlock knit fabric is ribbed on both the front and the back side of the fabric. These knits look smooth on both sides, and have little elasticity in the width, but good elasticity in the length. These fabrics are made by interlocking two ribbed fabrics that are each made with a single yarn.
