Abstract (en)
1. An untwisted high-strength polyester yarn for industrial use, wherein the filament-forming substance has a high average molecular weight corresponding to a relative solution viscosity (1.0 g of polymer in 100 ml of dichloroacetic acid at 25 degrees C) of about 1.90 to about 2.20 and the yarn has a heat shrinkage S200 of less than 7%, a degree of elasticity ED20 of at least 90%, a stability quotient SQ of at least 7.5 and a crystallinity of about 57 to about 65%.
