Isacord 1000m Polyester 0020 Black Thread

The tensile strength on this is incredible—I snapped three needles before I gave up trying to break a single strand. That 100% polyester build makes it far smoother through the machine than the rayon I used before.

This black Isacord thread sewed smoothly through my toughest denim logo without a single break. The polyester strength is noticeably better than the rayon I used before, and the 1000m spool means fewer changeovers. My embroidery machine ran at top speed with zero tension issues.

I’ve been through three spools of this black thread already, and it still hasn’t frayed or snapped on my densest logo patches. The 1000m length lasts ages, and the polyester strength is obvious when you pull it tight. It glides through the machine so smoothly that I barely have to adjust tension any
