Abstract

Se proporcionan fibras bicomponentes con curvatura mejorada. La fibra bicomponente comprende una primera región y una segunda región. La primera región comprende una primera composición de polietileno y la segunda región comprende una segunda composición de polietileno, en donde la primera composición de polietileno tiene una temperatura de cristalización (Tc) mayor que la temperatura de cristalización (Tc) de la segunda composición de polietileno. La fibra bicomponente se puede usar para formar un material no tejido.
