TO MANUFACTURE A MOLDING CELLULOSIC BODY, A CELLULOSIC AMINOXIDE SOLUTION IS PRESSED THROUGH A NOZZLE, DRIVING IT LATER THROUGH AN AIR SLOT, WHERE IT CAN BE STRETCHED. IT IS FINALLY COAGULATED IN A FILLED BATH. ACCORDING TO THE INVENTION, THE MINIMUM DIAMETER OF THE HOLE OF THE NOZZLE USED HAS A MAXIMUM OF 150 MICRONS, PREFERABLY 70 MICRONS, ASSUMING THE LENGTH OF THE NOZZLE CHANNEL AT LEAST 1000 MICRONS, PREFERABLY ABOUT 1500 MICRONS. THEREFORE, THE LENGTH OF THE AIR SLOT CAN BE REDUCED BELOW 35MM OR UP TO BELOW 10MM, SINCE A LONG CHANNEL NOZZLE ORIENTATION IS SUFFICIENT WITHOUT PRODUCING NEGATIVE EFFECTS. TEXTILES OF THE FIBERS MADE. A PREFERRED VERSION OF THE NOZZLE CHANNEL, PROVIDES FOR A CONICAL INLET SIDE AND ONLY THE CYLINDRICAL OUTLET SIDE. |
