Abstract

557,218. Artificial filaments, films, &c. BRITISH CELLOPHANE, Ltd. May 6, 1942, No. 6078. Convention date, May 6, 1941. [Class 2 (ii)] Regenerated cellulose filaments, ribbons, tubes, films or the like are obtained by extruding viscose into an acid coagulating bath in the presence of a small proportion of a polyalkylene oxide or polyalkylene glycol having a molecular weight of at least 400. Formation of deposits tending to clog the extrusion orifices is thus prevented or retarded. The polyalkylene oxide may be incorporated in the viscose, or in the coagulating bath, or in both. Preferably the polyalkylene oxide has a molecular weight not greater than 5,000. It may be obtained by heating the monomeric oxide in presence of an alkaline catalyst. A polyalkylene oxide which is soluble in water and benzene may be used. It may be obtained from ethylene oxide, propylene oxide, butylene oxide, cyclohexene oxide, or styrene oxide. The coagulating bath may contain sulphuric acid, sodium sulphate, zinc sulphate, and glucose. When the polyalkylene oxide is added to the viscose, the filaments and films are cleaner and show reduced lustre and increased water-sensitivity. When it is added to the coagulating bath the products show a more uniform cross-section but do not show increased water-sensitivity. The molecular weight of the polyalkylene oxide is calculated from the hydroxyl number.
