Abstract

Se divulga un proceso que comprende formar fibras, en donde cada una tiene al menos una primera región y una segunda región, en donde la primera región comprende una composición de interpolímero de etileno / a-olefina que se caracteriza por una densidad en el rango de 0,930 a 0,965 g/cm³, un índice de fusión (I₂) en el rango de 10 a 60 g/10 minutos, en donde el I₂ se mide de acuerdo con ASTM D1238, 190ºC, 2,16 kg, una distribución de peso molecular, expresada como la relación del peso molecular promedio en peso con respecto al peso molecular promedio en número (Mʷ₍GPC₎/Mₙ₍GPC₎) según lo determinado por GPC en el rango de 1,5 a 2,6, una tangente d a 1 radián/segundo de al menos 45, 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 (lCCD), y un ancho completo a la mitad del máximo del pico de alta temperatura es menor de 6,0ºC, y estirar las fibras hasta un alargamiento de al menos 20%, lo que aumenta el rizado de la fibra. El proceso puede incluir además formar un género no tejido a partir de las fibras y el estiramiento de las fibras puede ocurrir antes o después de la formación del género no tejido.
