How to Choose the Right Fabric Printing Process for Your Textile Material
The shortest version: match the ink chemistry to the dominant fibre. Reactive for cotton-class. Disperse for polyester. Acid for silk, wool and nylon. Pigment for blends or when workflow simplicity matters more than fibre-specific optimization. This guide walks each match.
The fibre → ink mapping
| Fabric | Primary process | Why |
|---|---|---|
| Cotton, linen, rayon, viscose | Reactive | Covalent bond with cellulose → deep color, soft hand |
| Polyester | Disperse (sublimation) | Dye sublimates into polymer → permanent, no-feel color |
| Silk, wool | Acid | Ionic bond with protein fibre → bright color, good hand |
| Nylon | Acid | Same protein-class chemistry as wool/silk |
| Blends | Pigment | Surface binder → works on any fibre mix |
| Mixed-fabric production | Pigment | One ink, one workflow, multiple fabric types |
Cotton-class fibres (cotton, linen, rayon, viscose)
Primary choice: Reactive printing
Reactive dye forms a covalent bond with the hydroxyl groups in cellulose. The bond is permanent at the molecular level - the dye becomes part of the fibre. This delivers:
- Deepest color saturation
- Softest hand (no surface coating)
- Excellent wash fastness
The trade-off: reactive printing requires the full wash-and-steam workflow (sizing, print, steam, wash, dry, fix, finish). That’s expensive in water, energy and labor.
Alternative: Pigment printing - simpler workflow, broader fabric flexibility, but slightly less color depth than reactive at the high-saturation end.
Polyester and synthetic fabrics
Primary choice: Disperse printing (sublimation)
Disperse dye sublimates from solid to gas under heat and bonds molecularly inside polyester fibres. The result is permanent, no-feel color with excellent wash fastness and outdoor durability.
Disperse printing is the standard for:
- Sportswear and swimwear (polyester / polyester-spandex)
- Soft signage (polyester banners)
- Polymer-coated rigid substrates (mugs, phone cases, panels)
Disperse only works on polyester (or polyester-coated substrates). It washes out of cotton.
Silk, wool, and selected nylon
Primary choice: Acid printing
Acid dye forms ionic bonds with protein fibres (silk, wool) and certain synthetic protein-analog fibres (nylon). Acid printing gives bright, vivid colors with good hand and acceptable wash fastness for premium fashion fabric.
Blended fabrics
Primary choice: Pigment printing
Blends create a problem for fibre-specific inks. A 50/50 cotton-polyester blend means:
- Reactive only bonds to the cotton side → washes out from polyester
- Disperse only bonds to the polyester side → washes out from cotton
- Acid doesn’t bond to either of these fibres
Pigment ink solves this by bonding to the fabric surface via a binder system, not via fibre chemistry. The same ink and process work on:
- Cotton-polyester
- Polyester-viscose
- Cotton-linen
- Cotton-nylon
- Knit blends
- Wool blends
See why pigment ink works on blended fabrics for the mechanism in detail.
When to use pigment even on pure fibres
Pigment isn’t only for blends. Choose pigment over the fibre-specific options when:
- Workflow simplicity matters - no wash, fewer steps, lower defect rate
- No-wash production is required - environmental compliance, tight water budgets
- Mixed-fabric daily output - one workflow, many fabrics
- Fast-fashion / small-batch / high-SKU turnaround
- Cost-per-m² is the constraint - pigment’s process simplicity usually wins on total cost

Equipment that handles all four processes
The H-Series R2R printers run reactive, disperse, acid AND pigment workflows on the same machine class. A factory dedicating machines to ink chemistry (one machine per ink to avoid cross-contamination during cleaning) can cover the full fabric range without buying purpose-built single-ink machines.
