Abstract
Regenerated cellulose filaments are produced by extruding viscose at a salt point between 6 and 15 into an aqueous acid coagulating bath containing at least 0.03 per cent by weight of a polyethylene oxide having a molecular weight between 600 and 6,000, sulphuric acid in a percentage of 1.0-1.3 times that of the caustic soda in the viscose and 3-15 per cent of zinc sulphate. Green viscoses may be spun and the freshly spun filaments are preferably subjected to stretching while passing through a hot dilute acid bath as described in Specification 467,500, [Group IV]. Specifications 557,218, [Group IV], and 634,868 also are referred to.
