Abstract

323,173. Kindermann, H. Dec. 4, 1928. Cellulose xanthates: cellulose solutions. - Artificial silk, staple fibres, films and the like are prepared from aqueous cellulose solutions, such as viscose or cuprammonium solutions, by preliminary coagulation, for example in an ammonium sulphate bath. followed by treatment in a strong sulphuric acid bath, containing from 45-50 per cent by weight of sulphuric acid, at a temperature below 10‹ C. whilst they are simultaneously subjected to a high tension. Filaments produced in this manner possess a very high lustre and a high web tenacity and it is possible to spin very fine denier filaments. In examples viscose is spun into a preliminary coagulating bath containing ammonium sulphate, the length of filament in the bath being 20-40 centimetres, and then treated in a bath containing 48 per cent of sulphuric acid by weight at 5‹ or 10‹ C., the length of filament in the water being 2 or 6 centimetres respectively; a cuprammonium cellulose solution is spun into a preliminary coagulating bath containing water at 60‹ C. or dilute caustic soda, the length of filament immersed being 15 centimetres and then treated in a bath containing 45 per cent by weight of sulphuric acid at 5‹ C., the length of filament immersed being 30-40 centimetres. Reference has been directed by the Comptroller to Specifications 264,161 and 283,481.
