Interlock knit fabric is one of the most widely used textiles in the Knitted Garment Manufacturing Industry, valued for its smooth texture, durability, and versatility. From baby clothing to premium casual wear, interlock fabric plays a key role in modern apparel production. This blog answers all the common questions people ask about interlock knit fabric—from quality and breathability to seasonal use and health concerns.
What Is an Interlock Knit Fabric?
Interlock knit fabric is a double-knit fabric created using two sets of needles that interlock loops together. This structure makes the fabric thicker, stronger, and more stable than single jersey knit. Both sides of interlock fabric look identical, giving it a neat and premium finish.
Why Is It Called Interlock?
It is called interlock because the loops from the front and back knit structures are interlocked with each other, creating a firm yet flexible fabric.
What Is Interlock in Fabric?
Interlock in fabric refers to a knitting technique where two rib structures are joined together. This results in a fabric that:
- Does not curl at the edges
- Has excellent stretch and recovery
- Feels soft and smooth on both sides
How Is Interlock Fabric Made?
Interlock fabric is produced on circular knitting machines using fine yarns such as cotton, polyester, or blends. The process involves:
- Two needle beds
- Simultaneous front and back loop formation
- Tightly interlocked stitches
This process is widely used in the Knitted Garment Manufacturing Industry for consistent quality and scalability.
What Does Interlock Fabric Feel Like?
Interlock fabric feels:
- Smooth and soft on the skin
- Slightly heavier than jersey knit
- Comfortable with a luxurious hand feel
Because of this texture, it is often used in babywear, T-shirts, nightwear, and premium loungewear.
What Is the Quality of Interlock Fabric?
The quality of interlock fabric is considered high due to:
- Excellent durability
- Better shape retention
- Reduced pilling
- Longer garment life
High-quality interlock knit fabric maintains its appearance even after repeated washing.
Is Interlock Knit Fabric 100% Cotton?

Which Fabric Is Best for Both Summer and Winter?

Is Interlock Knit Fabric Good for Babies?

That’s why it’s commonly used in baby bodysuits and sleepwear.
