Abstract

FIBRAS BICOMPONENTES CONSTAN ESENCIALMENTE DE POLIPROPILENO EN FASE CONTINUA, QUE TIENE DISTRIBUIDAS 20 A 45 % EN PESO DE FIBRILAS DE POLIETILENO LINEAL DE BAJA DENSIDAD (LLDPE) COMO FASE DISPERSA, ORDENADAS DE FORMA EXTENDIDA ESENCIALMENTE OMNIDIRECCIONAL. EL LLDPE FUNDIDO TIENE UNA VELOCIDAD DE FLUJO DE 12 A 120 G/10 MIN (ASTM), Y PREFERIBLEMENTE UNA DENSIDAD DE 0,92 A 0,94 G/CM3. LOS COMONOMEROS ALQUILENO DEL LLDPE PREFERIDOS TIENEN 4 A 8 ATOMOS DE CARBONO, ESPECIALMENTE 1-OCTENO, EN CANTIDAD DE 5 A 10 %. SE PUEDEN OBTENER FIBRAS DE MENOS QUE 30 DENIERS, PREFERIBLEMENTE MENOS QUE 15, QUE TIENEN ACTIVIDAD MEJORADA EN COMPARACION CON FIBRAS DE POLIPROPILENO.
