Abstract

PROCEDIMIENTO PARA PRODUCIR UN PRODUCTO DE HOJA SORBENTE. COMPRENDE: A) EXTRUIR EL MATERIAL LIQUIDO QUE FORMA LAS FIBRAS EN UNA CORRIENTE GASEOSA DE ALTA VELOCIDAD, PARA CONSEGUIR FIBRAS SOPLADAS EN FUSION; Y B) AGREGAR FIBRAS SORBENTES LIQUIDAS EN LA CORRIENTE GASEOSA DE LAS FIBRAS SOPLADAS EN FUSION, PARA OBTENER UNA BANDA CONTINUA FIBROSA COHERENTE Y QUE NO DESPIDE POLVO MEZCLA RESULTANTE DE LAS FIBRAS SOPLADAS EN FUSION Y DE LAS FIBRAS SORBENTES DE LIQUIDO. LAS FIBRAS SOPLADAS EN FUSION SON MICROFIBRAS QUE TIENEN UN DIAMETRO DE 10 MICROMETROS, EL MATERIAL FORMADOR SE SELECIONA ENTRE POLIPROPILENO, POLIETILENO, POLI(TEREFTALATO DE ETILENO Y POLIAMIDA Y LAS FIBRAS SORBENTES DE LIQUIDO SON DE ELEVADA SORBENCIA, TIENEN UN VALOR DE RETENCION DE ORINA SINTETICA DE 5 ML/G EN CORRIENTE GASEOSA DE EXTRUSION, SE APLICAN EN UNA CANTIDAD ENTRE 20 A 200 G/M2 POR CADA 100 G/M2 DE FIBRAS DE POLIMERO SOPLADAS Y SE ELIGEN ENTRE FIBRAS DE ACRILONITRILO CON UNA PORCION DE SU SUPERFICIE MODIFICADA, PARA FORMAR UN POLIMERO RETICULADO HIDROFILO. SE UTILIZAN COMO PAÑALES, COMPRESAS QUIRURGICAS, PAÑOS ALMOHADILLAS PARA PROTECCION DE CAMAS, COMPRESAS O PAÑOS HIGIENICOS.
