Scope

Main technical content: This document describes the method of using viscosity to determine the degree of polymerization (DP) of natural cellulose fibers dissolved in 1-butyl-3-methylimidazolium acetate (BMIMOAc) - dimethyl sulfoxide (DMSO). This document is suitable for natural cellulose fibers, and the method can also be used for natural cellulose fiber yarns and pure woven fabrics as a reference
