What kind of thread is ISACORD?

The short answer: ISACORD is a high-performance, 100% recycled polyester thread for machine embroidery. Its smooth, trilobal filament produces bright, defined stitching while offering the strength and durability required for professional production.

Our ISACORD range is supplied in the versatile 40 / Tex 27 size on 5,000 metre cones, making it suitable for everything from lettering and logos to larger filled designs.

What makes ISACORD different?

• 100% recycled polyester. A more sustainable choice with the durability and colourfastness expected from a professional polyester embroidery thread.
• Continuous filament. Long, smooth filaments help the thread run cleanly through the machine with minimal surface fuzz.
• Trilobal construction. The three-lobed filament reflects light to give embroidery a bright, lustrous finish.
• 40 / Tex 27 size. A versatile, all-round size suitable for a wide range of everyday embroidery.

Why choose polyester instead of rayon?

Rayon is known for its softness and shine, but polyester is often the better choice for items that will be worn, washed and handled regularly.

ISACORD combines an attractive sheen with excellent tensile strength, colourfastness and abrasion resistance. It also offers resistance to detergent, chlorine bleach and light, helping embroidered designs maintain their appearance over time.

This makes it particularly suitable for:

• Workwear and uniforms
• Sportswear and teamwear
• Hospitality clothing
• Branded bags and caps
• Frequently washed garments
• High-volume commercial embroidery

We always recommend testing the complete design on the intended garment before beginning a production run.

Why choose a 5,000 metre cone?

A 5,000 metre cone helps keep production moving by reducing the number of thread changes required during long designs, repeat logo runs and multi-head embroidery.

The larger format is ideal for commercial embroidery machines. It can also be used on domestic embroidery machines with a suitable external thread stand. Make sure the thread unwinds freely and follows the correct thread path.

Reliable colour and smooth running

We offer ISACORD for its dependable performance across professional embroidery applications. It unwinds smoothly, maintains consistent tension and provides reliable colour results across repeat jobs.

A quality thread works best as part of a well-balanced setup, so good digitising, suitable backing and a needle in good condition remain essential.

Certifications and care performance

Our ISACORD range offers several important certifications:

• Global Recycled Standard: GRS-certified options are available, providing independent verification of recycled content.
• OEKO-TEX STANDARD 100: Certified to Product Class I, Appendix 6, which covers products intended for babies and small children.
• PRO-Care: Tested to DIN EN ISO 15797 for use in industrially washed workwear and leasing textiles.

These certifications relate to the thread itself. If your contract requires certification for the completed garment, check the relevant finished-product requirements before production.

Getting the best results with ISACORD

• Choose the right needle. Nm 65 / No. 9 is a useful starting point for ISACORD 40, although the fabric and stitch density may require a different size or point.
• Run a production test. Test the design using the actual garment, backing, needle and bobbin thread.
• Adjust tension carefully. Check the thread path, needle and bobbin before changing a previously balanced tension setup.
• Store cones correctly. Keep them clean, cool and away from direct sunlight.
