Beschreibung
Zusammenfassung:	The invention relates to a method for making a high loft nonwoven web comprising crimped multicomponent fibers, the process comprising laying down the fibers on a spinbelt and pre-consolidating the fibers after laydown using one or more preconsolidation rollers to form a pre-consolidated web, wherein a first component of the fibers comprises a PP homopolymer and a second component of the fibers comprises a PP/PE copolymer, wherein the pre-consolidation rollers are operated at a temperature of smaller 110°C and/or a linear contact force of smaller 5 N/mm.
