WHY SUBLIMATION JERSEYS DON'T FADE: THE SCIENCE BEHIND THE PRINT

You've seen it happen with regular printed t-shirts — after a few washes, the print cracks, peels, and fades. Sublimation jerseys don't have this problem. Here's the science behind why.

HOW SUBLIMATION ACTUALLY WORKS

Sublimation printing uses a unique chemical process. Special inks are first printed onto transfer paper. When heat (around 200°C) and pressure are applied, the solid ink converts directly into gas — skipping the liquid phase entirely. This gas penetrates the polyester fibers and bonds at a molecular level. When it cools, the ink solidifies inside the fiber, becoming a permanent part of the fabric.

WHY IT DOESN'T FADE

Since the ink is embedded inside the fiber rather than sitting on top, there's nothing to crack, peel, or wash away. The print is literally part of the fabric. UV light, washing, stretching, and friction don't affect it because they can't reach the ink molecules trapped within the polyester structure.

WHY IT ONLY WORKS ON POLYESTER

Sublimation ink bonds specifically with polyester (synthetic polymer) fibers. Cotton and other natural fibers don't have the right molecular structure for sublimation bonding, which is why sublimation jerseys are always made from polyester or polyester-blend fabrics.

HOW LONG DO SUBLIMATION PRINTS LAST?

With proper care, sublimation prints easily outlast the fabric itself. The print will remain vibrant after 100+ washes. Most jerseys are retired due to fabric wear, size changes, or new designs long before the print shows any degradation.
