The present invention relates to a method for producing cellulose fibers having improved strength by hydrolyzing cellulose acetate fibers produced by melt spinning in a short period of time. More particularly, the present invention relates to a method for producing a cellulose acetate fiber, Hydrolyzing the cellulose fibers, and then washing and drying the cellulose fibers. According to the present invention, it is possible to produce cellulose fibers by hydrolysis of cellulose acetate fibers in a short time after melt spinning, thereby remarkably improving the productivity and also making it possible to produce cellulosic fibers having high tensile strength, And can be applied to products of various fields as needed. |
