摘要: Disclosed is a process for treating cellulosic fibers using an alkali metal hydroxide. The process first prepares the cellulosic fibers as a high consistency mixture with water and then adds an alkali metal hydroxide. The high consistency process is quite efficient and has been found to produce cellulosic fibers that are essentially uniformly treated. Also disclosed is a handsheet prepared from the treated cellulosic fibers for use is disposable absorbent products.
