If you’re developing a new T-shirt collection, choosing the right fabric is just as important as picking the perfect fit or color. The fabric not only affects the look and feel but also how your tee performs over time. Among the most common knit fabrics used for T-shirts are Single Jersey and Interlock—but they serve different purposes. So, which one should you choose?
Let’s break it down.
What is Single Jersey?
Single jersey is the most commonly used knit fabric for T-shirts. It’s made using one set of needles, resulting in a lightweight, flexible fabric with a smooth front and a slightly textured back.
✅ Pros:
-
Soft and breathable
-
Lightweight, ideal for casual wear
-
Cost-effective for bulk production
-
Great for prints
🚫 Cons:
-
Less structured
-
Can be slightly see-through in lighter colors or lower GSM
-
Tends to curl at the edges
Best For:
Fashion basics, promotional tees, streetwear or casual styles
What is Interlock?
Interlock is a type of double-knit fabric, meaning it’s made with two rows of needles. The result is a thicker, more stable fabric that feels soft on both sides.
✅ Pros:
-
Smooth finish on both sides
-
More opaque and structured than single jersey
-
Excellent durability and shape retention
-
Comfortable with a premium feel
🚫 Cons:
-
Heavier weight
-
Slightly higher cost
-
Less breathable than single jersey
Best For:
High-end tees, uniforms or workwear, cooler climates or layering
