Beschreibung
Zusammenfassung:	Provided are bicomponent fibers. The bicomponent fiber comprises a first region and a second region. The first region comprises a first ethylene/alpha-olefin interpolymer, and the second region comprises a second ethylene/alpha-olefin interpolymer. The first ethylene/alpha-olefin interpolymer has a highest peak melting temperature (Tm) less than 130° C. and at least 3.5° C. greater than a highest peak melting temperature of the second ethylene/alpha-olefin interpolymer. The bicomponent fibers can be used for forming nonwovens that in aspect have improved tensile strength, elongation at break, and/or abrasion resistance.
