Triblend
Fabric — one of 56 in the glossary
A fabric knit from three fibres, almost always cotton, polyester and rayon, in ratios around 50/25/25. Each does one job: cotton for hand and printability, polyester for shape retention and low shrinkage, rayon for drape and the soft, slightly sheer feel that made triblends a retail staple. The three fibres take dye differently, which is what produces the mottled heather look — and what makes print colour unpredictable, since the ink only fully covers part of the surface. Print triblends with a soft-hand or discharge-friendly approach and expect a vintage, slightly faded result rather than solid opacity.
Three fibres, three jobs
A triblend is usually around 50 polyester, 25 cotton and 25 rayon. Each is there for a reason.
Polyester gives strength, shape retention and the dye behaviour that produces heather colours. Cotton gives hand and something for ink to bond to. Rayon gives the drape and the soft, slightly slubby character that makes a triblend recognisable.
Take any one out and the fabric stops being what people buy triblends for.
Why they feel different
Rayon is a regenerated cellulose fibre with far more drape than cotton, so the fabric falls rather than hangs.
Triblends are also usually knitted light — often under 4 oz — which compounds the effect.
The consequence worth telling a customer is that they are less forgiving than a cotton tee: a light, draping fabric follows the body rather than skimming it.
At the press
The polyester carries disperse dye that migrates under heat, so a low-bleed ink and a lower cure are the usual answer on darker colours.
The rayon does not take water-based ink the way cotton does, so a recipe carried straight over from a cotton tee will disappoint.
Test on the actual blank. Triblends vary more between mills than cotton jersey does.
Common questions
- What is a triblend shirt?
- One knitted from three fibres, usually around 50 polyester, 25 cotton and 25 rayon. The polyester gives strength and heather colour, the cotton hand, the rayon drape.
- Why do triblend shirts feel so soft?
- Mainly the rayon, which drapes far more than cotton, combined with a light knit. The fabric falls rather than hangs.
- Can you screen print on a triblend?
- Yes, with low-bleed ink and a lower cure for the polyester, and with testing — the rayon does not take water-based ink like cotton, so a cotton recipe will not transfer.
