Abstract

1. A multifilament feed yarn from filament-forming polyesters for preparing high-strength multiply sewing yarns, which has a heat shrinkage S200 of 5 to 7 % and a reference extension (D45 ) at 45 cH/tex of less than 10 % and wherein the filament-forming polyester has a high average molecular weight corresponding to a relative solution viscosity (1.0 g of polymer in 100 ml of dichloroacetic acid at 258C) of more than 2.0.
