Abstract: Provided are bicomponent fibers with improved curvature. The bicomponent fibers comprise a first polymer region or first region and a second polymer region or second region. The first region according to embodiments of the present disclosure comprises an ethylene/alpha-olefin interpolymer and has a light scattering cumulative detector fraction (CDFLS) of greater than 0.1200, wherein the CDFLS is computed by measuring the area fraction of a low angle laser light scattering (LALLS) detector chromatogram greater than, or equal to, 1,000,000 g/mol molecular weight using Gel Permeation Chromatography (GPC). The second region comprises a polyester. The bicomponent fibers can be used for forming nonwovens.
