Abstract (en)
[origin: CA3138612A1] The invention relates to a spunbond nonwoven material made of continuous filaments, in particular crimped continuous filaments, the filaments being in the form of bicomponent filaments or multicomponent filaments and having an eccentric sheath-core configuration. The sheath of the filaments, in the filament cross-section, has a constant thickness d over at least 20% of the filament circumference.
Abstract (de)
Spunbond-Vliesstoff aus Endlosfilamenten, insbesondere aus gekräuselten Endlosfilamenten, wobei die Filamente als Bikomponentenfilamente bzw. Multikomponentenfilamente ausgebildet sind und eine exzentrische Kern-Mantel-Konfiguration aufweisen. Der Mantel der Filamente weist im Filamentquerschnitt gesehen über zumindest 20 % des Filamentumfanges eine konstante Dicke d auf.
