Abstract

EN UN DISPOSITIVO PARA REFRIGERAR FILAMENTOS POR SOPLADO CENTRAL MEDIANTE UNA TOBERA CENTRAL (4), SE DISPONE UN TUBO CERRADO (5) CON UNA LONGITUD ENTRE 200 Y 2000 MM, ENTRE LA TOBERA SOPLADORA (4) Y EL DISPOSITIVO DE PREPARACION (6). MEDIANTE LA DISPOSICION SEGUN LA INVENCION, LAS FIBRAS SE ENFRIAN HASTA TAL PUNTO QUE SE CONSIGUE UNA ORIENTACION MOLECULAR UNIFORME DENTRO DE LOS DIVERSOS FILAMENTOS, RESULTANDO ASI UN FILAMENTO MUY REGULAR.IN A DEVICE TO REFRIGERATE FILAMENTS BY CENTRAL BLOWING THROUGH A CENTRAL NOZZLE (4), A CLOSED TUBE (5) IS DISPOSED WITH A LENGTH BETWEEN 200 AND 2000 MM, BETWEEN THE BLOWER NOZZLE (4) AND THE PREPARATION DEVICE (6). THROUGH THE DISPOSITION ACCORDING TO THE INVENTION, THE FIBERS COOL DOWN TO THE POINT THAT A UNIFORM MOLECULAR ORIENTATION IS ACHIEVED WITHIN THE VARIOUS FILAMENTS, RESULTING IN A VERY REGULAR FILAMENT.
