Abstract

The invention relates to the technical field of a conductive fabric, and particularly relates to a high-conductivity high-flexibility high-water-washing-resistance fabric based on silver nanowires. According to the high-conductivity high-flexibility high-water-washing-resistance fabric based on the silver nanowires, in parts by weight, preparation raw materials at least include: 0.2 to 35 parts ofsilver nanowires and 65 to 99.8 parts of fabric. The high-conductivity high-flexibility high-water-washing-resistance fabric based on the silver nanowires has the advantages that the silver nanowireswhich has a specific length-diameter ratio and of which the surface is coated with a specific thickness of polypyrrole is introduced, and is compounded with the fabric by adopting a simple impregnating method so as to prepare the conductive fabric; and the silver nanowires with the high length-diameter ratio are radially arranged along fabric fibers, and the polypyrrole on the surfaces of the silver nanowires adheres the silver nanowires to the fabric fibers together so as to give high conductivity, high flexibility and high water washing resistance to the conductive fabric.
