Claim 0:
1. A preparation method of a modified polypropylene spunbond non-woven fabric, comprising:
modifying an organic compound to provide a modified nanocomposite material, the organic compound comprising tea polyphenol, naringin, and emodin, wherein the organic compound is in a weight percentage range of approximately 0.1%-5% based on a total weight of the modified polypropylene spunbond non-woven fabric,
wherein modifying the organic compound includes:
adding the organic compound into water to form a solution where the organic compound is fully dissolved; and adding a porous nanomaterial into the solution to form a mixture and stirring the mixture to form the modified nanocomposite material,
wherein the porous nanomaterial includes one or more of montmorillonite, zeolite powder, porous nano-TiO2 microspheres, and porous nano-SiO2 microspheres;

preparing a composite modifier, by performing: adding a fat-soluble solvent into the modified nanocomposite material, and grinding the modified nanocomposite material to provide the composite modifier; and
preparing the polypropylene spunbond non-woven fabric, by performing:
melt-mixing polypropylene chips in a twin-screw extruder,
after a melt of the polypropylene chips is formed in the twin-screw extruder, adding the composite modifier into the twin-screw extruder, and mixing the composite modifier with the melt of the polypropylene chips to form a mixed melt,
spinning and pulling the mixed melt to form a fiber net, and
hot-rolling the fiber net into a fabric by a hot-rolling machine to provide the modified polypropylene spunbond non-woven fabric.
