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

摘要

The present invention includes the step of spinning dope for lyocell manufacturing, the step of solidifying the spun dope to prepare a filament, the step of washing the filament, and the step of drying the washed filament, the drying step 105 The present invention relates to a method for producing lyocell filament fibers, lyocell filament fibers, and tire cords, which is carried out at a temperature not higher than ℃. ; The present invention is to perform a drying process under milder conditions than conventional lyocell filament fiber manufacturing, it is possible to prevent the damage of the yarn and improve the production efficiency of high quality products. ; Tire cord, lyocell, spinning, drying temperature
