| Standard acrylic textile binder | Forms a polymer film that holds pigment to the fabric as the ink dries and cures. | Ranges from soft to somewhat firm, depending on the formula, pigment load, and deposit. | General-purpose water-based pigment printing on compatible textiles. | A practical starting point for many jobs; fabric preparation and adequate curing affect adhesion and wash durability. | Follow the product’s specified time and temperature. Water-based inks commonly require the printed film to reach a cure temperature near 160°C (320°F), but requirements vary. |
| Self-crosslinking acrylic binder | Forms a pigment-binding film and is designed to develop additional resistance through crosslinking during curing. | Usually depends on the specific formulation and print deposit. | Water-based prints where improved wash or wet-rub durability is needed. | Crosslinking chemistry and performance vary. Observe the stated pot life and handling instructions if the product has them. | Use the supplier’s specified cure schedule; do not assume every self-crosslinking formula cures at the same temperature. |
| Soft-hand acrylic binder | Secures pigment while aiming to leave the printed area more flexible and less noticeable to the touch. | Generally softer and more flexible than a standard, heavily deposited print. | Lightweight garments and designs where a softer print feel is a priority. | Softness can come with trade-offs in opacity or durability, depending on the fabric, pigment, and amount of ink deposited. | Cure to the binder’s specified requirements and verify performance on the actual fabric. |
| Polyurethane (PU) binder | Forms a flexible film that binds pigment to the textile. | Often flexible; the final feel depends on the formulation and print thickness. | Applications that need flexibility or a particular balance of stretch and durability. | Not every PU binder is suitable for every fabric or process. Check compatibility, application guidance, and any required additives. | Use the product-specific cure schedule; temperature and time vary by formulation. |
| Silicone-based binder | Acts as a binder in specialized textile ink systems, helping form an elastic print film. | Can be soft and highly flexible when formulated for that result. | Specialty stretch fabrics or applications that call for an elastic print system. | Requires system-specific ink preparation and process controls. Confirm suitability for the substrate before production. | Follow the specific system’s cure instructions; silicone systems do not share one universal cure schedule. |
| Plastisol ink system | Typically does not use a separate textile binder: its PVC resin and plasticizer form the ink film when properly fused. | Can range from soft to substantial, depending on ink type, deposit, and print construction. | Conventional plastisol printing on compatible garments and fabrics. | It is a different ink system from water-based pigment ink, so a water-based binder is not automatically interchangeable. | Bring the entire ink deposit to the ink’s specified fusion temperature; check the product instructions and verify the print. |
| Choosing the best binder | The binder forms the film that holds pigment to the textile; the right choice depends on the ink system and print requirements. | Choose based on the desired softness, flexibility, and print thickness. | Match the binder to the fabric, desired appearance, production process, and durability needs. | Test adhesion, hand feel, stretch, and wash performance on the actual fabric before a production run. | Use the manufacturer’s current technical instructions. A temperature setting alone does not confirm that the ink film has fully cured. |
| Cure temperatures and performance are formulation-specific. The figures above are general guidance, not a substitute for the ink or binder supplier’s technical data and testing on the intended fabric. |
