Sublimation printing and triblend fabric come up together in search often enough to deserve a straight answer. Sublimation dye only bonds permanently to polyester fibers. Since triblend fabric is roughly half cotton, a full sublimated print on triblend will not hold the way it would on 100% polyester. Here is why, and what actually works instead.
Sublimation works by turning solid dye into a gas under heat and pressure, which then bonds permanently into the polymer structure of polyester fibers. Cotton fibers have no polymer structure for the dye to bond into, so any part of a garment that is cotton simply will not take the sublimated color the same way. Most sublimation-ready blanks are 100% polyester, or very close to it, specifically because the process depends on that fiber content.
Since triblend fabric is roughly 50% cotton, 25% polyester, and 25% rayon, a full sublimated print applied to it would only bond to about a quarter of the fibers. The result is typically a faded, washed-out version of the intended print, with the color looking thin and inconsistent, and it will continue to fade with each wash as the small amount of bonded dye wears down. This is not a workaround worth attempting for a design that needs true, vivid sublimation color.
Bear Grips Pro Shops: Custom Apparel for Your Team. No Minimums. Free Shipping.Placement printing, applying a design to a specific area like the chest, back, or sleeve using methods suited to cotton-blend fabric, is the standard and correct approach for triblend. This is the method used across the Bear Grips Pro Shops catalog for cotton, CVC, and triblend garments. It holds up well on triblend's textured, heathered base and does not require the fabric to be majority polyester the way sublimation does.
For a design that genuinely requires full sublimation color and coverage, the right fabric choice is a 100% polyester performance piece rather than triblend. In the Bear Grips catalog, performance polyester options include the Sport-Tek Men's Moisture-Wicking Tee ($23.86 VIP) and the Sport-Tek Youth Moisture-Wicking Performance Tee ($23.88 VIP), both better suited to a fully saturated, edge-to-edge printed look than a cotton-blend fabric like triblend.

Start FreeNot well. Sublimation dye bonds to polyester, and since triblend is roughly half cotton, a sublimated print will look faded and fade further over time. It is not the right print method for this fabric.
Sublimation dye becomes a gas under heat and bonds into the polymer structure of polyester fibers. Cotton has no equivalent structure for the dye to bond into.
