Method of preparing of natural graphene cellulose blended meltblown nonwoven fabric
This application describes a method of preparation of a natural graphene cellulose blended meltblown nonwoven fabric, 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 directly preparing the natural graphene cellulose blended meltblown nonwoven fabric by a meltblown process. 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 function can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fabric can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.
