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

摘要

The present invention comprises the steps of spinning the lyocell spinning dope through the spinneret, passing the filament radiated through the spinneret to the coagulation solution, washing the filament passed through the coagulation solution, and the washed filament It comprises a step of drying, the spinneret is an air inlet is formed in the center, relates to a method for producing a lyocell filament fiber, the lyocell filament fiber, and a tire cord to suck air through the air inlet.;The present invention enables uniform cooling in the air gap section during the spinning process of the lyocell multifilament fibers, and improves the stretching properties and processability of the fibers, thereby producing a lyocell filament fibers having excellent physical properties.;Tire cord, lyocell, spinneret, air intake
