▎ 摘　　要

NOVELTY - Modified biomass fiber comprises artificial spinning, graphene and functional additive. The artificial spinning is animal protein spinning, and the graphene is graphene powder. USE - Used as modified biomass fiber. ADVANTAGE - The fiber: is highly targeted; increases the use range; and the method utilizes different functional additives to achieve different functional effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fiber comprising (i) adding graphene, functional additive into a grinding device, grinding until the particle size becomes 100-120 nm, baking the pork skin protein at 55-60 degrees C for 3-4 hours, water content of pork skin protein is after the baking is 30-35 %, adding the pork skin protein in a stirring device, stirring into particles of uniform size and particle size of 1-1.2 cm, cutting the stirred pork skin, grinding and thinning by grinding device to particle diameter at 200-240nm, (ii) grinding the graphene, functional additive, and pork skin protein obtained in the step (i) in a mixing device, completely mixing, adding tackifier during the mixing process, where the ratio of quality to graphene, functional additives, pork skin protein is 1:(85-92), mixing properly by adding water and strengthening additive to obtain mixed material is a homogeneous, viscous fluid, and (iii) uniformly mixing the fluid raw material obtained in the step (ii) in a extruder, extruding corresponding fiber, cooling extruded modified biomass fiber, roller rolling air-cooled modified biomass fiber filaments, coiling bundled modified biomass fiber for collecting oil , and placing the oiled modified biomass fiber in shady and dry place.
