Abstract

Se divulga una fibra rizada que tiene un centroide de fibra y que comprende una primera región que tiene un primer centroide y una segunda región, en donde la primera región comprende una composición de interpolímero de etileno / a-olefina en una cantidad de al menos 75 por ciento en peso en función del peso total de la primera región y en donde la composición de interpolímero de etileno / a-olefina se caracteriza por un pico de baja temperatura y un pico de alta temperatura en un perfil de elución mediante un procedimiento de distribución mejorada de composición de comonómero (ICCD), y un ancho completo a la mitad del máximo del pico de alta temperatura es menor de 6,0ºC y la segunda región es un material que comprende un polímero que es diferente del interpolímero de etileno / a-olefina de la primera región y en donde las regiones están dispuestas de manera tal que al menos uno del primer centroide y el segundo centroide no es el mismo que el centroide de fibra.
