Also known as double-knit fabric, the Interlock fabric is made by positioning needles on a double-plate circular knitting machine in a vertical and opposite arrangement. This fabric can be created using various fibers and only requires one machine for production. This fabric is easy to handle and comfortable to wear, with a soft and absorbent texture that is perfect for activewear. It has a good amount of stretch and recovery, meaning it will bounce back to its original shape after being stretched.
