  • Improved fibre dissolution with enzymatic treatment
    Publication number: 20210172119
    Abstract: The present invention concerns a process for the dissolution of cellulose using an enzymatic treatment, followed by a chemical dissolution. Particularly, the invention relates to the utilization of oxidizing enzymes for said enzyme treatment step. The process of the invention will cause an improved dissolution of high molar mass cellulose fibres. The improved dissolution properties also cause an improved reactivity of the cellulose in subsequent reactions.
