Compared with the household tissue, the medical tissue has higher requirements and needs the antibacterial function of the tissue, in the preparation method of the antibacterial tissue disclosed in patent CN201110302656.5, the non-woven fabric substrate is soaked in the liquid medicine and then dried to prepare the domestic antibacterial tissue; the liquid medicine consists of coptis, aloe, radix sophorae flavescentis, saponin, borneol, boric acid, ethanol and distilled water. The preparation method of the domestic antibacterial paper towel is simple, the raw materials are low in cost and easy to obtain, the reaction conditions are mild, and the prepared antibacterial paper towel is natural and environment-friendly, has no side effect on human bodies and has a good antibacterial effect; has good application prospect. The preparation method has the following problems: put into the liquid medicine through the non-woven fabrics matrix and soak, dry and make domestic antibacterial paper handkerchief and can make the paper handkerchief become crumpled, need smooth again, the mode of soaking moreover can make the liquid medicine only attach to the paper handkerchief surface, it volatilizees to place for a long time and can lead to the antibacterial capacity of paper handkerchief to weaken, therefore we need a neotype paper towel of a section and preparation method to solve above-mentioned problem, satisfy people's demand.
