  • Process for producing regenerated cellulosic articles
    Patent number: 4076932
    Abstract: Regenerated cellulosic articles are produced by nitrosating and dissolving cellulose in a dialkylacylamide solvent, such as dimethylformamide, and regenerating the dissolved cellulose by passing into a coagulant bath. The coagulant comprises water or a 1 to 4 carbon atom aliphatic monohydric alcohol and a soluble reactive base, the latter in an amount ranging from 6% to 25% by weight of the regenerant. The process produces regenerated cellulose products of improved resistance to alkaline solubility.
