Reactive and pigment are the two dominant digital print chemistries on cotton. They look similar in promotional renders. They feel completely different in the hand. Reactive bonds dye into the fibre — the colour becomes part of the fabric. Pigment glues colour onto the surface — the colour sits on top of the fabric. Both have legitimate uses. Here’s how to choose.
FIBRE BOND vs SURFACE LAYER · HAND-FEEL · DURABILITY · COST
Reactive print chemistry forms covalent bonds with the cellulose fibres in cotton. The colour becomes part of the cotton at a molecular level — nothing sits on the surface, nothing changes the handfeel, nothing cracks or peels.
Pigment print uses pigment particles bonded to the fabric surface with a binder chemistry. The print sits on top of the fibre, not in it. That’s the right choice on synthetics (where reactive doesn’t work) and on heavy-duty outdoor textiles (where UV stability matters more than handfeel). It’s the wrong choice on cotton apparel and bedding.
Reactive dyes contain reactive groups (typically vinyl sulfone or monochlorotriazine) that form a stable covalent bond with the hydroxyl groups on cellulose fibres. After fixation under heat and steam, the dye is chemically part of the fibre.
Result: no surface layer. The cotton handfeel is preserved. The colour can’t crack, peel, or wash out short of fading the fibre itself.
Pigment print uses insoluble pigment particles suspended in a binder. When the print is cured under heat, the binder cross-links and glues the pigment particles to the fabric surface. The pigment never enters the fibre — it sits on top of it.
Result: a slight surface layer. On heavy fabrics this is invisible; on light cotton it adds detectable stiffness. The print is mechanically stable but can crack with extreme flex over thousands of wash cycles.
Where reactive and pigment differ on the metrics that matter for textile production decisions.
| Attribute | Reactive print | Pigment print |
|---|---|---|
| Substrate | Cellulose fibres only (cotton, linen, viscose) | Any — cotton, polyester, canvas, blends |
| Bond mechanism | Covalent chemical bond into fibre | Pigment + binder glued to surface |
| Handfeel impact | None — identical to unprinted cotton | Detectable on light fabrics; invisible on heavy canvas |
| Colour saturation | Deep, full-bleed, breathes through fibre | Strong on heavy fabrics; flatter look on light cotton |
| Wash durability | Typically 600+ cycles before measurable fade | 100–300 cycles; eventual cracking on flex points |
| UV stability | Good but not designed for direct sun | Excellent — engineered for outdoor use |
| Water consumption | Higher — wash-out cycle removes excess dye | Lower — no post-print wash needed |
| Energy consumption | Higher — steam fixation step | Lower — heat-cure only |
| Best for | Apparel, bedding, premium home textiles on cotton | Outdoor / synthetic textiles, low-volume merch |
| Worst for | Polyester, performance synthetics, outdoor sun load | Premium cotton apparel where handfeel is the brief |
The right print chemistry isn’t a brand preference — it’s a material science decision driven by what fabric you’re printing on and how the finished product gets used.
Both chemistries get used inside the Fabrixa range — reactive on cotton apparel, bedding, and indoor home textiles; pigment on outdoor poly-acrylic. Each product page lists the print method in its quick specs strip.
Pigment-printed cotton can pass eye-test in a photo and fail in the hand. Always sample on the actual substrate before committing to bulk — the difference between reactive and pigment shows up immediately on physical fabric.
A "digital print" line on a spec sheet doesn’t tell you which chemistry. Ask the supplier explicitly: reactive, pigment, sublimation, or DTF. Each has different downstream implications for wash and wear.
Wash a sample at the upper care-label temperature 10–20 times. Reactive print survives without measurable change. Pigment may begin to show fade at flex points (collar, cuff, kangaroo pocket).
Fabrixa’s default print chemistry on cotton is industrial reactive AOP — full coverage across the panel, no surface layer, the same European print process used by premium fashion houses. The chemistry choice is dictated by the substrate: reactive on cellulose, pigment on synthetics, sublimation on polyester (towels, mats, napkins).
Each Fabrixa product page lists the print method explicitly in its quick specs strip — no ambiguity, no “digital print” catch-all. You always know which chemistry your finished good was made with.
The single most reliable way to judge reactive vs. pigment is to handle them. Sample Pack ships physical swatches of every Fabrixa cotton base — reactive-printed test panels included — for hand-and-eye comparison against whatever else is on your supplier shortlist.
