Abstract

Procedimiento para la separación de celulosa regeneradaespecialmente de fibras que han sido obtenidas según el procedimiento de viscosa o al de cobrede mezclas con fibras nativas como algodónlinoramiolana y fibras artificiales sobre bases de caseínacomo por ejemplo thioláncaracterizado por el tratamiento de las fibras a temperatura ordinaria o elevada con una mezcla de ácido fórmico y sales que ligan al aguacom cloruro de calcio o cloruro de cinc.Process for the separation of regenerated cellulose, especially from fibers that have been obtained according to the viscose or copper process, from mixtures with native fibers such as cotton, lin-magnesium and artificial fibers on casein bases, such as thiol, characterized by the treatment of the fibers at ordinary or elevated temperature with a mixture of formic acid and water-binding salts such as calcium chloride or zinc chloride.
