Abstract
The invention relates to a spunbonded nonwoven having crimped multicomponent fibers, wherein a first component of the multicomponent fibers consists of a first thermoplastic polymer material comprising a first thermoplastic base polymer and a second component of the multicomponent fibers consists of a second thermoplastic polymer material comprising a second thermoplastic base polymer that is different from the first base polymer. The at least one of the first polymer material or the second polymer material is a polymer blend that comprises, further to the respective base polymer, between 1 and 10 weight percent of a high melt flow rate polymer that has a melt flow rate of between 600 and 3,000 g/10 min. The fibers have a linear mass density of less than 1.5 denier. The average crimp number of the crimped multicomponent fibers is in the range of at least 5 and preferably at least 8 crimps per cm in the fiber. The invention further relates to a method for making such spunbonded nonwoven, a multilayer fabric wherein at least one layer comprises such spunbonded nonwoven and a hygiene product comprising such spunbonded nonwoven or multilayer fabric.
