Abstract

The present invention relates to a nonwoven fabric comprising continuous spunbonded bicomponent fibers which consist of: 0 to 95% by weight of an aromatic polyester (A) in a core; to 50% by weight of a polyester blend (B) containing a) 65 to 95% of an aromatic polyester (BA) and b) 5 to 35% by weight of an aliphatic-aromatic polyester (BB) with a glass temperature below 0° C. in a sheath surrounding the core; and 0 to 5% by weight of at least one additive (C); wherein the % by weight are based in each case on the total weight of the components (A) and (B) and optionally (C); and wherein the aromatic polyesters (A) and (BA) are selected from the group consisting of poly(ethylene terephthalate) and poly(butylene terephthalate).
