▎ 摘　　要

NOVELTY - A medical wrapping fabric comprises a spunbond fabric layer (A) (S1), a meltblown fabric layer and a spunbond fabric layer (B) (S2) connected in sequence from outside to inside. The spunbond fabric layer (A) includes at least one layer of spunbond fabric (A). The meltblown fabric layer is a meltblown fabric layer comprising graphene particle-containing meltblown multi-fluff fibers that are entangled with each other. The spunbond fabric layer (B) includes at least one layer of spunbond fabric (B). The inner surface of the innermost layer of the spunbond fabric (B) is treated by polyvinyl alcohol antibacterial modified process. USE - Medical wrapping fabric. ADVANTAGE - The medical wrapping fabric has high tensile strength, sandwiches meltblown fabric layer between the upper and lower spunbond fabric layers through layered design, thus improving non-breaking and high antibacterial properties of the medical wrapping fabric, and improves bursting strength of the spunbond fabric (B) by antibacterial modification treatment of the inner surface of the innermost spunbond fabric (B) with polyvinyl alcohol. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the medical wrapping fabric, which involves: (S201) preparing spunbond fabric as spunbond fabric (A) and spunbond fabric (B); (S202) polyvinyl alcohol antibacterial modification of one surface of the spunbond fabric (B) to obtain an innermost layer of spunbond fabric (B); (S203) preparing meltblown fabric comprising graphene particle-containing meltblown multi-fluff fibers that are entangled with each other; and (S204) placing at least one layer of the spunbond fabric (A), at least one layer of meltblown fabric and at least one layer of the spunbond fabric (B) in sequence, and placing one side of the innermost layer of polyvinyl alcohol treated spunbond fabric (B) on the outermost side, hot-rolling, and reinforcing. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the medical wrapping fabric. (Drawing includes non-English language text). Spunbond fabric (A) (S1) Spunbond fabric (B) (S2)
