NOVELTY - A composite multifunctional protein regenerated cellulose fiber comprises 2.6-9.1 wt.% protein and 0.25-4.4 wt.% graphene. USE - Composite multifunctional protein regenerated cellulose fiber. ADVANTAGE - The composite multifunctional protein regenerated cellulose fiber has excellent antibacterial rate against Escherichia coli of greater than or equal to 85.6% and antibacterial rate against Staphylococcus aureus of greater than or equal to 85.5%. The preparation method of the fiber is less in protein loss. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite multifunctional protein regenerated cellulose fiber, which involves preparing a pre-crosslinked protein dispersion, preparing a multifunctional additive dispersion containing protein and graphene, preparing a blended spinning dope, spinning and carrying out post-treatment.
