Abstract

314,414. British Celanese, Ltd., Payne, R. W., and Roberts, R. P. Dec. 23, 1927. Cellulose esters and ethers, processes for making filaments from.-Artificial silks exhibiting a reduced lustre lor even a dull matte lustreless appearance, are obtained by the dry-spinning of solutions in volatile solvents of cellulose acetate or other organic acid esters of cellulose or of cellulose ethers, the solutions containing such a quantity of water and the spinning conditions being so chosen that the water exerts a precipitating action on the cellulose acetate &c. during the early stages of filament-formation. The quantities of water employed are preferably 20-30 per cent of the quantity of volatile solvent; the degree to which delustring takes place depends on the proportion of water added and the temperature of spinning, being generally greater as the proportion of water is higher and the temperature of spinning is lower. Specification 209,125 is referred to.
