Apparatus and method for manufacturing continuous filaments from synthetic polymers
Abstract
Abstract AN APPARATUS AND METHOD ARE PROVIDED FOR MANUFACTURING CONTINUOUS SYNTHETIC POLYMER FILAMENTS WHICH ARE ESPECIALLY USEFUL IN THE PREPARATION OF NON-WOVEN PRODUCTS. THE APPARATUS OF THIS INVENTION IS COMPRISED OF AN ELONGATED CLOSED CYLINDER WHICH HAS A SPINNERET ASSEMBLY AT AN UPPER END THEREOF, AN EXIT NOZZLE AT A LOWER END THEREOF AND MEANS FOR INTRODUCING A COMPRESSED FLUID INTO THE INTERIOR OF THE CYLINDER SO AS TO FORM A PRESSURIZED CHAMBER WITHIN THE CYLINDER. IN THE METHOD OF THIS INVENTION, THE POLYMER IS SPUN INTO FILAMENTS BY THE SPINNERET ASSEMBLY. THE SPUN FILAMENTS ARE THEN COOLED AND SOLIDIFIED BY THE COMPRESSED FLUID IN THE CHAMBER. THE SOLIDIFIED FILAMENTS THEN EXIT THROUGH THE EXIT NOZZLE ALONG WITH A PORTION OF THE COMPRESSED FLUID WHICH C AUSES THE FILAMENTS TO BE DRAWN SO AS TO IMPROVE THEIR PHYSICAL PROPERTIES.
