This application describes a method of preparation of a natural graphene cellulose blended fiber, which comprises using a graphite powder as a raw material for preparing a graphene solution, adding the graphene solution to a slurry formed by mixing and dissolving a wood pulp with N-methylmorpholine N-oxide (NMMO), removing the water content thereof to form a spinning dope, and then spinning the spinning dope by a Dry-Jet Wet method to manufacture a natural graphene cellulose blended fiber. The present method does not require a highly toxic hydrazine hydrate solution. Further, by increasing the adding ratio of the graphene solution in the manufacturing process, control of the antistatic properties and thermal transferring functions can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fibers can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.
