Abstract: Nonwoven fabric containing endless fibers and bonding impressions or bonding points, the endless fibers containing at least 80 wt. % of aliphatic polyesters, the endless fibers containing a first component making up at least 55% of fiber surface, the first component containing at least one aliphatic polyester and at least 0.1 wt. % of an additive, the additive containing an amide group, the additive corresponding to a general formula (i) or (ii) or (iii)(i) R1-(CO)—NH2 (ii) R1-(CO)—NH-R2 (iii) R1-(CO)—NH-R3-NH—(CO)—R2 wherein R1, R2, R3 are aliphatic hydrocarbon chains.

Abstract: A nonwoven fabric comprising a plurality of filamentary strata, wherein the fabric comprises —a first stratum (A), which forms an outer surface of the nonwoven fabric and comprises continuous multi-component filaments comprising a component, which forms at least 20% of the surface of the filaments and bonds within the first stratum (A) and has its melting point at least 5° C. lower than the melting point of the other components of the filaments of the first stratum (A), and —a second stratum (B), which comprises continuous multi-component filaments comprising a component, which forms at least 20% of the surface of the filaments and bonds within the second stratum (B) and has its melting point at least 5° C. lower than the melting point of the other components of the filaments of the second stratum (B), —wherein the bulk density of the fabric is lower than 60 kg/m3.
