Beschreibung
Zusammenfassung:	Provided are bicomponent fibers with curvature. The bicomponent fiber includes a first region and a second region. The first region includes a polypropylene blend and second region includes an ethylene/alpha-olefin interpolymer composition. The polypropylene blend includes a polypropylene homopolymer and a propylene-ethylene interpolymer, wherein the propylene-ethylene interpolymer has a density of from 0.860 to 0.880 g/cc and a melt flow rate of greater than 12 g/10 min. The ethylene/alpha-olefin interpolymer composition has a density of greater than 0.920 g/cc and a melt index (I2) of from 10 to 25 g/10 min. The bicomponent fiber can be used to form a nonwoven.
