Abstract
Provided is a multifunctional viscose fiber comprising viscose fibers, graphene and nanosilver, wherein the nanosilver is loaded on the graphene in situ. Provided is a method for preparing multifunctional viscose fibers including: a) dispersing graphene in an aqueous solution to obtain a graphene dispersion solution, b) dissolving a silver salt into the graphene dispersion solution, and adding a reducing agent to perform a reduction reaction to obtain a nanosilver-loaded graphene dispersion solution, and c) uniformly mixing the nanosilver-loaded graphene dispersion solution with a viscose solution, and performing spinning to obtain the multifunctional viscose fibers. Experimental results show that as compared to viscose fibers with no nanosilver-loaded graphene added, the multifunctional viscose fibers have a far infrared temperature increase performance increased by not less than 100%, an ultraviolet protecting coefficient increased by not less than 70%, and an antibacterial activity reaching 99.9% and increased by not less than 100%.
