Poly Blocker DTF Transfers for Sportswear

DTF with a built-in dye-blocking layer, so white numbers, names and logos stay white on red, navy and black polyester kit. Checked by our team before it goes to print.

Why ordinary transfers go pink on sports kit

Dyed polyester, especially reds, dark blues and blacks, can release dye when it is heated. That dye creeps into a normal transfer and turns clean whites pink or grey, sometimes days after pressing. Poly Blocker transfers carry an extra grey blocking layer behind the white that stops it, so kit stays sharp through a season of washing.

Works on

Dyed and sublimated polyester, performance and moisture-wicking fabrics, and nylon and polyester blends: football and rugby kit, running tops, performance polos and teamwear. It works on cotton too, but our standard DTF gang sheet is better value there.

Pressing

Polyester: 135°C for 8 seconds. Cotton and 50/50 blends: 140°C for 10 seconds. High to firm pressure, with a silicone or parchment sheet on top. Let it cool for 5 to 10 seconds, then peel the film away warm. For extra hold, cover it again and press for another 5 to 10 seconds. Leave it 24 hours before the first wash, then wash inside out at 30°C and avoid tumble drying. Test on a spare garment first; polyester scorches easily. Pressing and application FAQs.

Artwork, the short version

For a finished sheet, use a PNG with a transparent background, or a single-page PDF, laid out on a 560 x 1000mm canvas at 300 dpi. Keep shirt numbers and names as solid shapes, text at least 5mm tall and lines at least 0.018 inches (about 0.46mm), and leave 5mm between designs. Only upload club crests and sponsor logos you have permission to print. More in our artwork guide.
