What is Interlock Fabric?
Interlock fabric is a double-knit fabric made from two separate 1×1 rib weaves that are interconnected. This construction makes the fabric smooth on both sides, stable, and slightly thicker than single jersey knits.
Interlock is reversible, durable, and soft, making it a popular choice for apparel, activewear, baby clothing, and premium knitwear.
