摘要： The present disclosure provides for a bicomponent fiber that includes a first region formed of a condensation polymer and a second region formed from a polyethylene blend. The polyethylene blend includes (i) an ethylene-based polymer having a density of 0.920 g/cm3 to 0.970 g/cm3 and a melt index, I2, as determined by ASTM D1238 at 190° C. and 2.16 kg of 0.5 to 150 g/10 minutes; (ii) a maleic anhydride-grafted polyethylene; and (iii) an inorganic Brønsted-Lowry acid having an acid strength pKa value at 25° C. of 1 to 6.5, wherein the polyethylene blend has a 0.03 to 0.5 weight percent of grafted maleic anhydride based on the total weight of the polyethylene blend. The first region is a core region of the bicomponent fiber and the second region is a sheath region of the bicomponent fiber, where the sheath region surrounds the core region.
