Sportswear Sublimation: Temperature and Speed Settings

Sportswear is one of the toughest sublimation applications. Because fabrics are lycra/elastane blends — elastic, thermally sensitive. 5 °C too hot → fabric melts, color fades. 5 °C too cold → ink won't bond, washes out. Finding the right parameter means thinking about fabric type, calender speed, and print density together.

Starting temperature by fabric type

Handling elastane blends

Lycra/elastane fabrics lose their stretch if held over 200 °C for too long. Critical for sportswear — the form has to keep its elasticity. Keep temperature around 195 °C, dwell limited to 30-45 seconds. If color still won't bond, raise pressure instead of speed: belt tension can run 0.5-1 bar higher.

How to prevent fading

Sublimation transfer runs on the temperature × dwell × pressure triangle. If colors look dull or fade in wash: • Check temperature first — does the thermocouple show the truth? Measure drum surface with an independent probe. • Increase dwell 5-10 seconds (slow down speed). Most fading comes from inadequate transfer time. • Check transfer paper quality. Use 80-100 gsm quality sublimation paper — low gram paper has insufficient color capacity. • Ink quality: use original sublimation ink (Epson, Mimaki, Sawgrass). Copies transfer weakly.

Why sublimation fails on blend fabrics

Sublimation chemically bonds disperse dyes to polyester molecules. This bond doesn't form on natural fibers like cotton, wool, silk — disperse dye sits on the surface and washes off. On 50/50 polyester-cotton, the print shows but pale (only polyester portion bonds). For sportswear, always pick 85%+ polyester fabric.

Recommended start on Mearic machines

**MM series (mid-volume):** 200 °C, 2 m/min, 0.5 bar — standard polyester jersey. **MB series (industrial):** 195 °C, 1.8 m/min, 0.6 bar — elastane stretch fabrics. Speed is dynamically adjusted from PLC, synchronized with the paper-width sensor. **MR series (continuous roll):** 205 °C, 2.5 m/min, 0.4 bar — long-roll polyester mesh. These values are the starting point. Run the first 10 meters as test prints, inspect, optimize in 2-3 °C / 0.2 m/min steps.
