  • Method for the production of rayon
    Patent number: 4159299
    Abstract: A method and apparatus for the production of rayon and for the continuous processing of filaments is disclosed. Filament threads are formed in a spinning column in which they are completely regenerated and stretched by the action of a constant temperature coagulating solution. The total length of the spinning column considerably exceeds the length of the column portion in which the rayon yarns are formed. The coagulating solution, after the formation of the rayon yarns, flows at a speed less than that of the threads at the column outlet eliminating an entire zone to the treatment of spun threads with strong high-temperature solution, heretofore necessary for complete regeneration of the threads.
