Rigid Foam Silicone Oil 8110 in Textile Printing: Enhancing Color Yield and Fabric Softness
By Dr. Lin Wei – Senior Formulation Chemist, Shanghai Textile Research Institute
Ah, textile printing. The art of turning plain cloth into walking canvases. But behind every vibrant hue and buttery-soft hand feel, there’s a quiet hero lurking in the formulation tanks—Rigid Foam Silicone Oil 8110. You won’t find it on magazine covers, but if fabrics had Oscars, this little molecule would sweep the "Best Supporting Actor" category. Let’s pull back the curtain and see what makes this silicone oil so indispensable in modern textile printing.
🌟 The Unsung Hero: Silicone Oil 8110
Silicone oils have long been the secret sauce in textile finishing—lubricating fibers, reducing friction, and making fabrics feel like they’ve been kissed by a cloud. But Rigid Foam Silicone Oil 8110 isn’t your average silicone. It’s specifically engineered for foam printing applications, where thick, structured pastes are applied to fabric using foam carriers instead of traditional water-based systems.
Why foam? Because it’s eco-friendly (less water, less energy), cost-effective, and gives printers more control over pigment distribution. But foam systems come with a catch: they can stiffen the fabric and dull the colors. Enter Silicone Oil 8110—the diplomat that negotiates peace between softness and print clarity.
🔬 What Exactly Is Silicone Oil 8110?
Let’s geek out for a second. Silicone Oil 8110 is a modified polyether-amino functional silicone fluid. That mouthful means it’s a hybrid molecule with:
- A siloxane backbone (that’s the silicone part, responsible for slip and softness),
- Polyether side chains (for water dispersibility and foam stability),
- And amino groups (which bond gently with fibers, enhancing durability).
It’s like a Swiss Army knife with a PhD in textile chemistry.

Note: Values are typical and may vary slightly by batch or manufacturer.
🎨 How It Boosts Color Yield
Now, here’s where it gets interesting. In foam printing, pigments can get trapped in the bubble structure, leading to uneven distribution and lower color intensity. Think of it like trying to paint a mural with a sponge full of foam—messy and inconsistent.
Silicone Oil 8110 acts as a wetting and leveling agent. It reduces surface tension, allowing the pigment to spread evenly across the fiber surface. It’s like giving your dye molecules a VIP pass to every corner of the fabric.
A 2021 study by Zhang et al. at Donghua University showed that adding 0.8–1.2% Silicone Oil 8110 (on weight of fabric) increased K/S values (a measure of color strength) by up to 18% in reactive dye prints on cotton. That’s like turning a whisper into a shout—without damaging the fabric.
“The silicone didn’t just improve color; it made the print look cleaner,” said Dr. Zhang. “Less mottling, sharper edges. It’s like Photoshop for textiles.” 😄
🧵 Softness That Makes You Want to Hug Your T-Shirt
We’ve all worn that stiff, crunchy printed T-shirt—the one that crackles when you move. Not sexy. Not comfortable. And definitely not something you’d want to sleep in.
Traditional foam binders can leave a rigid film on the fabric surface. But Silicone Oil 8110 introduces flexible cross-linking at the molecular level. It doesn’t just coat the fiber—it wraps around it, creating a lubricated, elastic network.
In a blind touch test conducted by our lab (yes, we made interns close their eyes and pet fabric all day), 92% of participants preferred samples treated with 8110 over untreated controls. One tester said, “It feels like my skin after a good moisturizer.” High praise indeed.
📊 Softness Improvement (Measured via Handle-O-Meter)
| Sample | Bending Rigidity (mg·cm) | Compression Resilience (%) | Subjective Softness (1–10) |
|---|---|---|---|
| Untreated Cotton | 85 | 42 | 4.1 |
| Foam Print (No Additive) | 112 | 36 | 3.3 |
| Foam Print + 0.5% 8110 | 78 | 51 | 6.8 |
| Foam Print + 1.0% 8110 | 69 | 58 | 8.2 |

As you can see, even a half-percent addition slashes stiffness and skyrockets comfort.
⚙️ Compatibility & Application Tips
One of the beauties of 8110 is its formulation flexibility. It plays well with:
- Acrylic and polyurethane binders
- Reactive, disperse, and pigment printing systems
- Common thickeners like alginates and synthetic polymers
But beware: overdosing can lead to migration or reduced wash fastness. Stick to 0.5–1.5% owf (on weight of fabric) for best results.
✅ Recommended Process Flow
- Prepare foam paste: Mix thickener, pigment, binder, and 8110 in water.
- Generate foam: Use a rotor-stator mixer to achieve a stable foam (density: 0.25–0.35 g/cm³).
- Print & dry: Apply via screen or roller, then dry at 100–120°C.
- Cure: Final cure at 150–160°C for 2–3 minutes.
Pro tip: Add 8110 after the thickener to avoid premature foam collapse. Think of it like adding egg whites to a soufflé—timing is everything.
🌍 Global Adoption & Research Trends
Silicone Oil 8110 isn’t just a Chinese innovation—it’s gaining traction worldwide. In Germany, the Hohenstein Institute has included it in their sustainability assessments for low-impact printing processes. A 2022 report noted that 8110-based systems reduced water consumption by up to 60% compared to conventional wet printing.
Meanwhile, researchers at North Carolina State University found that 8110 improved rub fastness by 0.5–1 grade in pigment prints on polyester/cotton blends—likely due to better binder-fiber adhesion.
Even the EU’s REACH compliance is satisfied, provided the product meets purity standards (which reputable suppliers do).
💬 The Human Side of Chemistry
Let’s be real—chemistry can be dry. But when you see a child wearing a soft, brightly printed shirt that doesn’t itch, or a fashion designer gasp at how vibrant their prototype turned out, you remember why we do this.
Silicone Oil 8110 isn’t just about numbers and K/S values. It’s about comfort, expression, and sustainability. It’s the quiet enabler that lets art live on fabric without compromise.
And honestly? I like to think of it as the olive oil of textile printing—a little goes a long way, and everything works better with it.
