NOVELTY - The method for preparing nonwoven fabric involves (a) preparing graphene oxide containing interlayer water, (b) preparing graphene oxide powder (i) intercalated with barium tungstate according to interlayer water-containing graphene oxide, (c) preparing a graphene oxide powder (ii) intercalated with europium oxide, samarium oxide, gadolinium oxide and barium oxide according to graphene oxide powder (i), (d) preparing X-ray radiation protection function lead-free powder according to graphene oxide powder (i) and the graphene oxide powder (ii), and (e) preparing nonwoven fabric according to the X-ray radiation protection function lead-free powder. USE - Method is useful for preparing nonwoven fabric. ADVANTAGE - The nonwoven fabric is lead-free and lightweight, has high durability and excellent X-, gamma -ray protection function, physical and mechanical properties and textile processing properties.
