  • IMPROVEMENTS RELATING TO THE COLD-ALKALI PROCESS FOR THE PRODUCTION OF REGENERATED CELLULOSIC FIBERS
    Publication number: 20240352626
    Abstract: A method and processing facility for producing regenerated cellulosic fibers includes extruding a spinning solution into a coagulation bath which contains a salt and preferably an alkali to produce the fibers. The spinning solution may include cellulose dissolved in an aqueous solvent comprising NaOH and ZnO. The coagulation bath may have a pH-value of at least seven. The method may also include a continuous process of applying to the fibers in a never-dried state a crosslinking agent with two or more reactive groups and heating the fibers to a curing temperature while maintaining the never-dried condition to produce a reaction between the crosslinking agent and the cellulose of the fiber.

  • PROCESS FOR THE TREATMENT OF LYOCELL FIBERS
    Publication number: 20220074082
    Abstract: The present invention relates to a process for the treatment of lyocell fibers, comprising the step of contacting the fiber with at least one treatment medium, at least one treatment medium containing an amount of a crosslinking agent, wherein the cross-linking agent is capable of crosslinking cellulose under alkaline conditions and has a solubility in water at 20° C. of 20 g/l or less, and further comprising the step of treating the fiber with the cross-linking agent under alkaline conditions, characterized in that the cross-linking agent is added to the fiber in the form of a suspension or in solid form. The present invention also relates to lyocell fibers obtainable by the process of the present invention.
