How to Apply 3D Silicone Patches onto Football Shirts

How to Apply 3D Silicone Patches onto Football Shirts (Heat Press & Household Iron)

🌡️ Quick Reference Guide

Pressing Method Temperature (°C) Front Press (Tack) Inside-Out Press (Main Bond) Pressure Level
Professional Heat Press 140°C – 145°C 8 – 10 seconds 20 seconds Medium-High (4 bar)
Household Iron ~140°C (Polyester/2 Dots) 12 seconds 25 – 30 seconds Heavy Body Weight

🏭 Method 1: Professional Heat Press

  1. Set Machine Parameters: Set your heat press to 140°C – 145°C and pressure to Medium-High.

  2. Pre-press the Jersey: Press shirt for 3 seconds with a Teflon sheet.

  3. Position Silicone Patch: Place the 3D silicone patch on the target sleeve or chest area.

  4. Step 1 — Front Tack (8–10 Seconds): Cover with a Teflon sheet and press briefly to tack patch position. (Rubber insulates heat, so top pressing alone won’t melt the glue).

  5. Step 2 — Inside-Out Main Bond (20 Seconds): Turn jersey inside out. Cover patch back with a Teflon sheet and press firmly for 20 seconds to melt adhesive directly through shirt fabric.

  6. Cool Down: Allow garment to rest flat until cold before testing rubber flexibility.

🏠 Method 2: Household Iron

  1. Iron & Surface Prep: Set iron to Polyester / Synthetic (~140°C). Turn steam 100% OFF. Work on a hard, flat tabletop.

  2. Pre-iron Area: Iron target area for 3 seconds.

  3. Position & Cover: Position silicone patch and cover with parchment paper.

  4. Step 1 — Front Tack (12 Seconds): Press straight down vertically with firm force to hold patch in place.

  5. Step 2 — Inside-Out Main Bond (25–30 Seconds): Flip jersey inside out. Place parchment paper over the back side and apply maximum downward body weight for 30 seconds.

  6. Set Under Weight: Place a heavy book over the patch for 5 minutes while it cools.

💡 Pro Tip: Dense 3D silicone rubber blocks top-down heat transfer. Pressing from the inside-out is mandatory to properly melt thermo-glue into football shirt fabric without melting or distorting the rubber details on the front.
