262 NITRIC ESTERS The hollow fibers still contain an acid solution within them. In order that this acid may be washed out, they are pulped or broken up into short lengths by means of apparatus like that which is used in the manufacture of paper. A Jordan mill cuts the fibers off rather sharply, leaving square eDds, buf a beater tears FIGURE 63 Nitrocellulose Fibers after Beating (132X) (Courtesy Western Cartridge Company ) them, leaving ends which appear rough and shredded under the microscope and which result on the whole m the better opening up of the tubular fibers The two machines are usually used in series. A weak solution of sodium carbonate is added during the pulping to neutralize the acid which is liberated The pulping is continued until the desired fineness has been attained as shown by laboratory test.
NltfROCELLULOSE 263 The pulped fibers still retain acid adsorbed or occluded on their surface. This is removed by poaching the nitrocellulose, by boiling it again, first for 4 hours with fresh water with or without the addition of dilute sodium carbonate solution, 97 then for 2 hours with water without addition of soda, then twice with water for 1 hour each time. The material is then washed at least 8 times by thorough agitation with cold water, and by decantation each time of at least 40% of the liquid. After the washing, the material undergoes screening, where it passes through apertures 0.022 inch in width, wringing, whereby its moisture content is reduced to 26-28%, and finally packing for shipment or for storage in containers which are hermetically sealed. Guncotton is made in substantially the same way as pyrocellulose except that a stronger mixed acid containing approximately 24% nitric acid, 67% sulfuric acid, and 9% water is used. Long-fiber high-grade guncotton is usually manufactured by the pot process and with the use of mixed acid which is nearly anhydrous. Iron pots are generally used. For the nitration of 4 pounds of dry cotton, 140 pounds of acid is introduced into the pot and the cotton is immersed in it, pressed down, and allowed to digest for 20 or 30 minutes. The contents of several pots are centrifuged at once, and the product is stabilized in the same way as pyrocellulose except that it is not pulped. There can be no doubt that, in the standard method of stabilizing nitrocellulose, there are, among the results which the poaching accomplishes, at least some which would have been accomplished much earlier during the boiling if the material at that time had been pulped. This seems especially evident with respect to the hydrolysis of easily hydrolyzed material adjacent to the inner wall of the tubular fibers. Olsen, 98 discussing the standard method, has written, "The preliminary boiling tub treatment reduced the acidity of the fibers and of the interstitial material, but the pulping process, by macerating these fibers, has set free an additional amount of acid. It is, therefore, necessary to repurify the pyrocotton by boiling." He discovered that a marked reduction in time and in cost could be secured by carrying out the pulping operation prior to the hydrolyzing boils. If the pulping is done at 97 Not more than 10 gallons of sodium carbonate solution (1 pound per gallon) for every 2000 pounds of nitrocellulose (dry weight). 98 U. S. Pat. 1,798,270 (1931).
