Abstract

302,956. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Sept. 21, 1927. Ammoniacal-copper cellulose solutions for artificial silk producion are made by pressing raw cellulose material into thin sheets of paper-like form, avoiding as far as possible a'l unnecessary mechanical and chemical treatment and then effecting solution with the cellulose so prepared.
