About Cotton/Spandex (95/5)
95% Cotton / 5% Spandex (Elastane/Lycra)

Step-by-Step Pressing Process
- 1
Pre-press the fabric
Set your heat press to 305-315F. Press the substrate for 3-5 seconds without the transfer to remove moisture and flatten wrinkles. Standard pre-press. The 5% spandex does not significantly change heat requirements from pure cotton.
- 2
Position the transfer
Center the UV DTF Transfers on the fabric in the correct placement location. For apparel, use a heat-resistant tape or alignment ruler to verify placement before pressing.
- 3
Apply heat and pressure
Press at 305-320F for 12-15 seconds with medium pressure. Ensure the platen makes full, even contact with the transfer area.
- 4
Peel the carrier film (warm peel)
Wait 5-15 seconds after pressing, then test a corner. When the carrier film releases smoothly without resistance, peel in one steady motion. Do not peel while the film is still hot or completely cold.
- 5
Finish press
Place a Teflon sheet or parchment paper over the peeled design. Re-press at 305-315F for 5-8 seconds with medium pressure. Use Teflon sheet. Standard finishing press.
Pre-Press Details
Standard pre-press. The 5% spandex does not significantly change heat requirements from pure cotton.
Finish Press Details

UV DTF-Specific Notes for Cotton/Spandex (95/5)
UV DTF transfers use a UV-cured pressure-sensitive adhesive, which is distinct from standard DTF. Cotton/Spandex (95/5) is primarily a textile substrate, which is not the designed use case for UV DTF. If UV DTF is being tested on this material, clean the surface with isopropyl alcohol and burnish firmly. Adhesion results will vary and are not guaranteed on fabric substrates.
Common Pitfalls on Cotton/Spandex (95/5)
- Spandex begins to degrade at around 350F. Stay below 320F to preserve elasticity.
- Do NOT stretch the garment during placement or pressing — the transfer must be applied on relaxed fabric.
- After pressing, the garment will still stretch. The DTF transfer will stretch slightly but can crack if the garment is stretched more than 15-20%.
- Placed on a stretched garment, the transfer will wrinkle when the garment relaxes. Always press on relaxed fabric.
Pro Tips for Cotton/Spandex (95/5)
- 5% spandex barely affects DTF settings. Treat almost identically to 100% cotton with a slightly lower ceiling.
- 310F for 12 seconds is a reliable starting point.
- Inform customers that DTF prints on stretch fabrics should not be placed over areas that stretch significantly (like ribbed side panels).
- Position designs over the stable front panel, not over seams or stretch zones.
Frequently Asked Questions
What temperature should I use for UV DTF on Cotton/Spandex (95/5)?
Press at 305-320F (152-160C). Start at the lower end of the range and increase only if adhesion test fails.
How long should I press UV DTF transfers on Cotton/Spandex (95/5)?
Press for 12-15 seconds at medium pressure.
Hot peel or cold peel for UV DTF on Cotton/Spandex (95/5)?
Use warm peel for Cotton/Spandex (95/5). Wait 5-15 seconds after pressing, test a corner, then peel smoothly when the film releases without resistance. This method gives the best adhesion results on this fabric type.
What are the most common mistakes when pressing UV DTF on Cotton/Spandex (95/5)?
Spandex begins to degrade at around 350F. Stay below 320F to preserve elasticity. Do NOT stretch the garment during placement or pressing — the transfer must be applied on relaxed fabric. Tip: 5% spandex barely affects DTF settings. Treat almost identically to 100% cotton with a slightly lower ceiling.
