Abstract
The present invention is directed to a method of preparing continuous lyocell fibers by melt blowing techniques, a pulp useful for making lyocell fibers and to the fibers produced by the method. In particular, the method enables high throughputs of fibers of cotton-like deniers. The fibers are readily cut into staple lengths and can be spun into yarns with excellent knitting and weaving characteristics which dye exceptionally well.
