PROFIPOLY core spun threads have a special structure allowing a high relative strength and a cotton-like handle. The base of the single yarn is high-strength polyester filament yarn, which is spun with polyester staple fibres. Single yarn manufactured in this manner is then twisted into a semi-finished sewing thread. Dyeing is performed on high-pressure dyeing machines, and the dyeing process itself is fully automated. A sewing finish is then applied to the thread, with a subsequent laboratory check. The result is sewing thread with a high seam strength and resistance to stress during the stitching process. They meet all the demands required by modern high-performance sewing machines, guaranteeing break-free sewing at a high rpm of the sewing machine.


A wide range of use is guaranteed by its high strength at low fineness of the thread. The thread provides quality seams when making underwear, shirts, swimming costumes, blouses, towels, knitwear, women's and men's garments, sportswear, blankets and bed linen.

It is manufactured in selected shades according to the sample book

Packages: 1 000m, 5 000m
