Heat Transfer Silicone Ink for Transfer Labels
Heat transfer silicone ink is a specialized ink used to create durable, flexible, and high-quality transfer labels for textiles. Unlike traditional plastisol or water-based transfers, silicone-based transfers offer superior stretchability, softness, and wash resistance, making them ideal for sportswear, activewear, and high-end apparel.
🔹 Key Features of Silicone Heat Transfer Inks
✅ Soft & Flexible – Stretches with fabric without cracking (ideal for spandex, polyester blends).
✅ Excellent Wash Resistance – Withstands industrial laundering (up to 50+ washes).
✅ High Opacity – Vibrant colors even on dark fabrics.
✅ Eco-Friendly – Free from PVC, phthalates, and harmful solvents.
✅ Durable Adhesion – Bonds well with synthetic fabrics (polyester, nylon, etc.).
🔹 How Silicone Heat Transfer Labels Work
Printing – Silicone ink is screen-printed onto a release paper or PET film (not fabric directly).
Drying/Curing – The ink is dried (not fully cured yet) to create a transfer film.
Heat Press Application – The transfer is pressed onto fabric (typically 150–170°C for 10–15 sec).
Peel & Finish – After cooling, the carrier sheet is peeled, leaving a soft, flexible print.

🔹 Best Practices for Silicone Heat Transfers
✔ Fabric Compatibility – Works best on synthetic fabrics (polyester, nylon, blends).
✔ Optimal Curing – Ensure full curing (proper time/temperature) for maximum durability.
✔ Peel Technique – Cool slightly before peeling to avoid stretching.
✔ Storage – Keep transfers in a cool, dry place to prevent sticking.
