Reactive vs sublimation printing: which is right for your fabric?

Reactive printing chemically bonds water-based dye into natural fibres — cotton and linen — for deep, soft, wash-fast colour. Sublimation uses heat to fuse dye into polyester for vivid, durable prints on synthetics. The right choice is decided by your fabric: natural fibre → reactive; polyester → sublimation.

Fabrixa runs both — reactive for natural-fibre apparel, home textiles and fabric by the metre (Portugal, Spain), sublimation for selected synthetic home-textile items (the Netherlands) — so this comparison is from a maker that uses each where it performs best. MOQ 1, white-label.

Definitions

Two methods, two chemistries

What is reactive printing?

Reactive printing applies fibre-reactive dyes that form a covalent chemical bond with the cellulose molecules in natural fibres like cotton and linen. The colour becomes part of the fibre rather than a layer on top, so reactive prints stay soft to the touch and hold their colour through repeated washing — the technique behind Fabrixa’s natural-fibre range.

Print reactive dye onto the natural fabric
Steam-fix so the dye bonds to the fibre
Wash off surplus dye
Dry — a print with no added surface texture

What is sublimation printing?

Dye-sublimation uses heat (around 180–200 °C) to turn solid dye into a gas that fuses into polyester (or polymer-coated) fibres. It delivers vivid, photographic, edge-to-edge colour that won’t crack or peel — but it does not bond to untreated natural fibres such as cotton.

Print the design onto transfer paper (or directly)
Heat-press so the dye sublimates into the polyester
Done — no wash-off stage

What each print actually looks like

Same artwork, two chemistries. Reactive sinks into the fibre; sublimation fuses into the polymer. The fabric under the ink is what decides which one you get.

Reactive on cotton

Bonded into the fibre

Dye becomes part of the cotton — deep, matte colour with a soft hand and no surface layer. Holds through 600+ wash cycles.

Sublimation on polyester

Fused into the polymer

Dye gas-fuses into polyester for vivid, photographic, edge-to-edge colour that won’t crack or peel — on synthetic bases only.

Side by side

Reactive vs sublimation, compared

	Reactive	Sublimation
Best fibre	Natural — cotton and linen	Polyester / poly-coated
Colour bond	Dye covalently bonded into fibre	Dye gas-fused into polyester
Hand-feel	Soft, no surface layer	Soft on poly; nil on coated items
Wash & light fastness	Excellent on natural fibre	Excellent on polyester
Colour character	Deep, rich solids	Vivid, photographic
Works on cotton?	Yes	No — needs polyester / coating
Typical products	Tees, hoodies, dresses, cushions, duvet covers, curtains, fabric by the metre	Towels, sportswear, fleece, mats, poly home items
Eco note	Water-based dyes; GOTS / OEKO-TEX natural bases	No wash-off water stage; polyester base

Durability

How each print survives real use

Wash-fastness — reactive bonds survive 600+ wash cycles on cotton; sublimation locks into polyester and won’t wash out.
No crack or peel — neither method sits on the surface as a film (unlike DTG, DTF or vinyl), so there’s nothing to crack, flake or peel.
Hand-feel over time — reactive stays soft because no layer is added; sublimation keeps the poly fabric’s own hand.
Colour over washes — reactive holds deep, rich solids; sublimation holds vivid, photographic gradients.

Decision

Which should you choose?

Choose reactive when…

Your product is cotton or linen
You want a soft hand-feel with no print “patch”
You need deep, durable colour on apparel or home textiles

Choose sublimation when…

Your product is polyester or performance fabric
You want edge-to-edge photographic colour on synthetics
Items like towels, sportswear, fleece and mats

Quick chooser

Start with your product

The fabric decides the method. Our cotton apparel, home textiles and fabric by the metre print reactive; our synthetic home-textile lines print sublimation. Each links through to its range.

In practice

Which does Fabrixa use?

Both, matched to the fabric: reactive for natural-fibre apparel, home textiles and fabric by the metre (Portugal, Spain); sublimation for the synthetic home-textile lines where it performs best (the Netherlands). Every base is OEKO-TEX, with GOTS organic cotton across the apparel range — and you can order from a single unit (MOQ 1).

FAQ

Common questions

Is reactive printing better than sublimation?

Neither is universally better — it depends on the fabric. Reactive wins on natural fibres (cotton, linen); sublimation wins on polyester.

Can you sublimate onto cotton?

Not durably — sublimation needs polyester or a polymer coating. For cotton, reactive printing is the right method.

Which lasts longer in the wash?

Both are highly wash-fast on the fabric they are designed for — reactive on natural fibres, sublimation on polyester. Mismatch the method to the fabric and durability drops.

Which is more sustainable?

Reactive uses water-based dyes on natural, often GOTS-certified fibres but includes a wash-off stage; sublimation has no wash-off water stage but prints onto polyester. Fabrixa runs both on OEKO-TEX bases.

Does Fabrixa do both?

Yes — reactive for natural fibres and sublimation for selected synthetic items, so each design is produced with the method that suits its fabric.
