Bleaching 100% polyester fabric before sublimation printing is NOT recommended, and here's why:
Why You Shouldn't Bleach Polyester Before Sublimation:
Polyester is a synthetic fabric — bleaching it can damage the fibers, leading to:
Yellowing or discoloration
Weakening of the material
Uneven surface for sublimation
Sublimation needs a stable, high-polyester surface — bleaching may interfere with how well the ink bonds with the fabric.
What You Can Do Instead:
Start with white or light-colored 100% polyester fabric – this gives the best sublimation results without needing any bleaching.
If you want a “bleached” look , use bleach spray techniques on cotton-blend shirts (like 65% polyester / 35% cotton), but:
Do it after dye sublimation printing.
Be aware that sublimation colors will fade more on blends.
Do not bleach 100% polyester before sublimation. It’s better to choose white polyester fabric and apply your design directly for vibrant, long-lasting results.
