发明名称 METHOD FOR PRODUCING A CELLULOSE SOLUTION IN AN AQUEOUS AMINE OXIDE, SAID SOLUTION HAVING AN INCREASED THERMAL STABILITY
摘要 The invention relates to a method for producing a cellulose solution in an aqueous amine oxide, preferably N-methyl-morpholine-N-oxide, for processing to form cellulosed moulded bodies according to the Lyocell method, whereby said solution has an increased thermal stability. Cellulose is suspended in an aqueous amine oxide and the suspension is converted into the cellulose solution. The inventive method is characterised in that the base use of the cellulose used for producing the solution and of the optionally used additives is detected in a dispersion in aqueous amine oxide solution and in that the cellulose solution is formed by adding a base quantity which matches the detected own consumption of the cellulose and optionally the additives. Cellulose solutions having a stability which is essentially independent from the provenance of the used cellulose can be formed.
