3D Puff Embroidery on Hoodies

The industry standard is closed-cell EVA foam at 45–65 kg/m³ density. Softer foam (35 kg/m³) collapses under wash; harder foam (80+ kg/m³) resists needle penetration and breaks needles. 2 mm foam gives a subtle raise; 3 mm gives the bold streetwear look. Stack two 2 mm layers only when the digitiser has increased density accordingly — otherwise the top layer shows through the stitches.

Puff satin needs 0.35–0.4 mm density (vs 0.5 mm for flat embroidery) to fully hide the foam. Underlay is a single zigzag at 2 mm to hold the foam down without perforating it. Satin columns should be 6–12 mm wide — narrower and the stitches don't lift; wider and the satin looks starved. Pull compensation is set 30% higher than flat work because the foam lifts the top of the stitch.

• No fine detail under 3 mm — foam swallows it.
• No sharp inside corners — foam tears; use rounded corners at 1.5 mm minimum radius.
• Combine puff (bold letters) with flat (fine detail) on the same design for hierarchy.
• Never puff on a stretch panel — foam cracks after 20+ washes.
• Keep puff off the kangaroo pocket opening and hood seam — bulk conflicts with wear.

• Uneven puff = foam density wrong for the machine speed.
• Foam showing through = density under 0.35 mm; re-digitise.
• Foam bleed at edge = burn-away temperature too low; increase iron / laser pass.
• Cracks in wash = puff over interlock or stretch panel.
