MELT-SPINNING SPINNERET AND METHOD FOR MELT-SPINNING SYNTHETIC FIBER

摘要

PROBLEM TO BE SOLVED: To prevent the adhesion of foreign matters around a polymer extrusion nozzle without causing fiber unevenness and fiber breakage.;SOLUTION: This melt-spinning spinneret is characterized by forming a small circular space 6 between the housing 4 and spinneret case 1 of a spinning machine, using the space 6 as a gas passage, and disposing a shield 11 for changing the direction of the flow of the gas supplied from the gas passage into a direction approximately parallel to the bottom plate of the spinneret plate 2, on the upper whole inner periphery of a heating cylinder 5.;COPYRIGHT: (C)2004,JPO
