What Is Cotton Interlock Fabric?
Interlock Knit Fabric Structure Explained
Cotton interlock fabric is a double-knit fabric constructed on interlock knitting machines. Unlike single jersey knits, interlock cotton is formed by two sets of needles working together, creating a fabric that looks identical on both sides.
This interlock knit fabric structure provides:
A smooth, flat surface
Improved dimensional stability
Reduced curling at the edges
A slightly heavier and more substantial hand feel
From a technical perspective, interlock knitting is widely recognized as one of the most stable knit structures in the textile industry. For a deeper explanation of knit fabric construction, Textile School offers a clear technical overview of interlock knitting principles.
Cotton Interlock vs Other Cotton Knits
Compared with other cotton knits, cotton interlock fabric stands out in several ways:
Interlock vs Jersey Knit
Jersey knit fabrics are lighter and more flexible but tend to curl and distort more easily. Cotton interlock holds its shape better, making it ideal for premium garments.Interlock vs Rib Knit
Rib knits offer more stretch but are less smooth and less suitable for large-area printing. Interlock cotton provides a cleaner surface for printed designs.
According to Encyclopaedia Britannica’s overview of knitted fabrics, double-knit structures like interlock are favored where durability and fabric stability are required.
