Estimating the term…
The invention relates to a method for making a spunbonded high loft nonwoven web comprising crimped multicomponent fibers, the process comprising continuously spinning the fibers, directing the fibers to a spin-belt by deflectors and/or air streams, laying down the fibers on the spinbelt and pre-consolidating the fibers after laydown using one or more pre-consolidation 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.

A spunbonded nonwoven fabric comprising crimped multicomponent fibers comprising a first component that comprises PP homopolymer and a second component that comprises a PP/PE copolymer, and obtained by a method comprising continuously spinning multicomponent fibers, directing the multicomponent fibers to a spin-belt by deflectors, air streams, or both, laying down the multicomponent fibers on the spin-belt, and pre-consolidating the multicomponent fibers after laydown utilizing one or more pre-consolidation rollers to form a pre-consolidated web, wherein the pre-consolidation rollers are operated at a temperature of below 110° C., at a linear contact force of lower than 5 N/mm or both.
