Spunbond Nonwoven Material Made of Continuous Filament and Apparatus for Producing Spunbond Nonwoven Material

摘要

The present invention relates to a spunbond nonwoven material made of continuous filaments, in particular crimped continuous filaments, wherein the filaments are in the form of bicomponent or multicomponent filaments and have an eccentric sheath-core configuration. The sheath of the filament at the cross-section of the filament has a constant thickness d over at least 20% of the circumference of the filament.
