Production of stabilized cellulose solutions for use in the Lyocell process comprises dissolving cellulose in an aqueous amine oxide in the presence of a calculated amount of base

摘要

Production of a solution of cellulose in an aqueous amine oxide by suspending cellulose and optional additives in the aqueous amine oxide and converting the suspension into a solution comprises: (a) determining the base consumption of the cellulose and optional additives when dispersed in the aqueous amine oxide; and (b) adding the corresponding amount of base during the preparation of the cellulose solution.
