Abstract
186,608. Duckworth, G. Sept. 28, 1921, [Convention date]. Furs and furriery; treatment preliminary to tanning.-Skins, especially those of rabbits, hares, kangaroos, and opossums, are treated for the removal and recovery of the fur and hair without impairing the usefulness of the skins for the production of leather, by immersing them in a solution of sulphite of soda, then in a solution of ammonia, and finally subjecting them to a swe,ating process. The solution of sulphite of soda is of about 3 per cent strength, and the skins are soaked therein for about 12 hours to remove blood and fatty matter. The solution of ammonia contains about 4 pints of 880 ammonia in 4 gallons of water, and the treatment therewith is carried out in a closed vessel at a temperature of 80- 120‹ F. for about 12 hours. The skins are left in the sweating-vat for 12-24 hours, the time varying according to the strength of the ammonia solution used and the temperature at which the sweating is carried out. The hair is then removed by scraping or brushing, which operation should be carried out as soon as possible after the removal of the skins from the sweating-vat.
