Fabric with low air permeability and high density

The utility model relates to the technical field of fabrics, and particularly discloses a low-air-permeability high-density fabric, which comprises a fabric body, the fabric body comprises weft yarns and warp yarns, the fabric body is formed by crossing the weft yarns and the warp yarns, the weft yarns comprise polyacrylonitrile fiber layers, polystyrene fiber layers and polyester fiber layers, and the polyacrylonitrile fiber layers comprise polyacrylonitrile fiber layers, polystyrene fiber layers and polyester fiber layers. The warp yarn comprises a polyamide fiber layer, a glass fiber layer and a polyurethane fiber layer, and the polyacrylonitrile fiber layer is located on the top of the polystyrene fiber layer. Through the cooperation of the fabric body, the weft yarns, the polyacrylonitrile fiber layer, the polystyrene fiber layer, the polyester fiber layer, the warp yarns, the polyamide fiber layer, the glass fiber layer and the polyurethane fiber layer, the wear-resistant fabric achieves the advantage o
