The invention provides a method for preparing a nano-silver blended natural cellulose spunbonded non-woven fabric, which is prepared by adding polyvinyl alcohol (PVA) powder to pure water to prepare a gel state protective agent, and then adding silver nitrate (AgNO3) and Sodium borohydride (NaBH4), the polyvinyl alcohol protecting agent is reduced with silver nitrate to form a nano silver sol, and then the nano silver sol is added to the cellulose slurry which is mixed with the oxidized methyl phenanthrene and dissolved in the cellulose slurry. After removing moisture, a dope of nano-silver natural cellulose is formed, and then the mucus is squeezed out from the spun by a spunbond to form a long cellulose tow, and the long cellulose tow is cooled and pulled. Stretching, so that they are stacked on the net to form a mesh-like non-woven fabric, and then through the water needle rolling, drying and winding procedures, the nano silver natural cellulose spunbonded non-woven fabric is prepared. |
