Abstract: 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.

Abstract: 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.
