Double knit fabric is a popular choice for garments that need structure, comfort, and durability. It is thicker than regular jersey fabric and has a smooth finish on both sides, making it easy to sew and wear.
In this guide, we’ll explain what double knit fabric is, how it’s made, and what double knit fabric is used for, along with practical tips for choosing the right one when shopping double knit fabric online.
What Is Double Knit Fabric?
Double knit fabric is a type of knit fabric made using two sets of needles instead of one. This creates a thicker, more stable fabric that looks the same on both sides.
Unlike single jersey, it does not curl at the edges and holds its shape better. You’ll often find double knit fabric cotton options, as well as blends with polyester or elastane for added stretch and durability.
Common double knit fabric examples include scuba, interlock knits and ponte de roma.
4 Key Characteristics of Double Knit Fabric
1. Thicker and More Structured
Double knit is heavier than regular jersey, making it ideal for garments that need more structure.
2. Smooth on Both Sides
Both sides of the fabric look similar, which makes cutting and sewing easier.
3. Stable with Less Curling
Unlike lighter knits, it does not roll at the edges, which is great for beginners.
4. Moderate Stretch
It still stretches, but not as much as lightweight jersey, giving a more polished look.
How Is Double Knit Fabric Made?
Double knit fabric is created using a special knitting machine with two needle beds:
1. Two Yarn Systems – Two sets of yarns are used at the same time
2. Interlocking Loops – The loops interlock between the front and back layers
3. Thicker Construction – This creates a double-layered structure
4. Finishing – The fabric is dyed and treated for softness and stability
This construction is what gives double knit fabric its signature thickness and durability.
