PROCESS FOR PREPARING LYOCELL FILAMENT FIBER, LYOCELL FILAMENT FIBER AND TIRE CORD

摘要

A process for making lyocell filament fiber, the lyocell filament fiber, and the tire cord are provided to make the lyocell filament fiber by improving an elongation property and uniformity of the fiber. A process for making lyocell filament fiber includes the following steps of: emitting dope through a spinneret; passing the filament emitted through the spinneret through a congelation solution; washing the passed filament; and drying the filament. The spinneret has an air intake formed on a central part and inhales air through the air intake with normal speed of wind 1 or 100 m3/hr.
