If you’re looking for a smoother, thicker, and more luxurious alternative to single jersey — interlock is the fabric to know.
At HEM APPAREL, we use interlock for premium T-shirts, polos, babywear, and products that require both softness and structure. Here's why it's worth considering.
🧵 What is Interlock?
Interlock is a double-knit fabric, made using two sets of needles.
Unlike single jersey, interlock has two smooth sides — making it reversible and denser.
✅ It’s softer, stretchier, and more stable than single jersey
✅ Fabric lies flat — no curling at the edges
🔁 Interlock vs Single Jersey

📦 Why Use Interlock?
-
Smooth finish → perfect for minimalist or premium pieces
-
Dense weave → more opaque, covers better
-
Natural stretch → comfortable without needing spandex
-
Less prone to deformation → holds its shape wash after wash
✅ It gives garments a high-end feel without needing heavy weight
👕 Best Use Cases
-
Premium unisex tees
-
Kidswear and baby clothing
-
Base layers or light sweaters
-
Polo shirts
-
Modern uniforms
⚠️ Considerations
-
Interlock is more expensive than single jersey — use it where the touch & thickness matter
-
Not ideal for very lightweight, flowy designs
-
Because of its tight structure, it may not drape as freely
🧠 HEM APPAREL’s Tip:
Use interlock when you want a clean silhouette, soft structure, and upscale impression — especially in short-run premium tees or sensitive-skin products.
We help brands compare jersey and interlock with swatchbooks and GSM testing before committing.
