1. A method for preparing a wall-cloth having a laminated core, the method comprising:
applying a fiber sheet on a surface of a prime coating layer when the prime coating layer solidifies, the fiber sheet comprising fibers of a network structure;
applying a second coating layer on a surface of the fiber sheet;
exerting pressure on the second coating layer against the prime coating layer to allow coating material of the second coating layer to moisten the fibers and to permeate into meshes of the network structure, thereby forming a laminated core layer; and
solidifying the laminated core layer to form the wall-cloth with the laminated core;
wherein the second coating layer is transparent or semi-transparent;
wherein the network structure possesses a 3D interpenetrating network with the fibers spread in 3D directions;
wherein at least a part of the fibers interweave in at least two layers, and the fibers in different layers cross each other to form meshes spreading in different directions;
wherein junctions of the fibers in one of the layers locate in a mesh or meshes of another one of the layers, and a direction of the fiber in one layer or at least some layers are different with a direction of the fibers in another layer or other layers;
wherein the junctions of the fibers are linkable together to form connection points by melting and/or cohering, and a percent of the connection points is 1% to 100%;
wherein the fiber of the fiber sheet has a diameter of 1 μm-5000 μm, the fiber sheet has a thickness of 0.1 mm-10 mm and has a density of 10 to 300 g/m2;
wherein the meshes of the fiber sheet have an aperture size of 0.1 mm to 10 mm;
wherein at least one of the prime coating layer, the second coating layer, and the fiber sheet comprises a bacterial inhibitor or a substance that releases the bacterial inhibitor; or
at least one of the prime coating layer, the second coating layer, and the fiber sheet comprises an electrically conductive substance to provide a function of electromagnetic shielding; or
at least one of the prime coating layer, the second coating layer, and the fiber sheet comprises a magnetic substance to provide a function of magnetic absorption, which allows attachment to a surface of an object by magnetic force; or
at least one of the prime coating layer, the second coating layer, and the fiber sheet comprises a phase change material to provide a function of thermal storage through phase transition; or
at least one of the prime coating layer and the second coating layer comprises a waterproof layer; or
at least one of the prime coating layer and the second coating layer comprises a fireproof coating; or
the fiber sheet comprises a fireproof sheet or a non-combustible sheet; or
the second coating layer is an anti-graffiti layer; or
the prime coating layer is a thermal insulation layer.
