Abstract
Regenerated cellulose filaments, having a very high tenacity both in the conditioned state and in the wet state, good dimensional stability, a high modulus of elasticity in the wet state, and a swelling value less than 55%, are made by spinning viscose of viscosity at least 150 poises at 15 DEG C., of g value at least 45 and containing a cellulose of degree of polymerization of at least 400, in a coagulating bath which has an acid content of at most 40 g./l. of sulphuric acid and contains not more than 1% anhydrous zinc sulphate, in the presence of formaldehyde. Preferably the degree of polymerization of the cellulose is above 500, the g value of the viscose is at least 55, and the coagulating bath contains 8-40 g./l. sulphuric acid, 10-120 g./l. anhydrous sodium sulphate, and is substantially free of zinc sulphate. The formaldehyde may be included in the viscose, or may be added to the coagulating bath, suitably in a proportion of 1-40 g./l. The coagulating bath temperature may be from 10 DEG -40 DEG C., preferably 15 DEG -30 DEG C. Filaments emerging from the coagulating bath may be treated in a second hot acid bath, e.g. stretched by at least 100% and advantageously by at least 200%, in either bath or between the baths. In spinning continuous filaments, the spun filament may be wound on bobbins and allowed to relax in acid conditions. In making staple fibres the spun filaments, after emergence from the coagulating bath, or from the second bath, is used, may be led through a further hot acid bath and cut to staple fibre. The filaments can also be cut in the acid state, and the fibres then fixed in order to obtain curled fibres. Filaments so made have a tenacity of at least 5 g./denier in the conditioned state and 4 g./denier in the wet state, a high wet modulus and a wet-state elongation of less than 3% under a load of 0,5 g./denier. They have a substantially circular cross-section, swelling values generally less than 50%, and are little modified by treatment with 6% caustic soda.
