Gunold STIFFY 1640 Iron On
Coated for ironing
For medium-weight knits like polo shirts, using an iron-on embroidery nonwoven is strongly recommended.
Iron-on embroidery stabilizer designed specifically for stretch and elastic fabrics.
The PE-coated surface temporarily bonds to the fabric when ironed on, providing excellent stability and preventing distortion during embroidery. Thin, soft, and lightweight, it adds minimal bulk and can be torn away quickly and cleanly after stitching, leaving little to no residue. Ideal for knitwear and elastane fabrics, it improves embroidery quality while saving time and increasing productivity.
For medium-weight knits (polo shirts)
Processing Recommendations:
- Hoop the base fabric with the nonwoven in an embroidery hoop.
- Embroider the design.
- Remove the hoop and carefully tear away the nonwoven.
Material Composition: Base Material: 75-80% Cellulose, 20-25% Polyester
Coating: 100% Polyethylene
Öko-Tex certified:

- Iron STIFFY 1640B onto the reverse side of the fabric with the coated (smooth) side facing the fabric.
- Hoop the fabric with the stabilizer.
- Embroider the design.
- Remove the hoop.
- Carefully tear away the stabilizer – it separates very easily despite the iron-on bond.
