Problems solved by technology
Due to the high toughness of copper, the diameter of the copper wire needs to reach a certain value to ensure that it meets the tensile strength of the papermaking; on the other hand, due to the dehydration of the papermaking, the number of copper meshes cannot be increased infinitely. The production of watermark paper c

Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as figure 2 As shown, a non-woven watermarking net for obtaining high-definition watermarks. The watermarking net is made of nickel and formed into a nickel watermarking net 4 with a flat mesh structure by electroplating. In the nickel watermarking net, several nickels arranged vertically and horizontally The upper and lower ends of the wire 3 are on the same plane and the joints formed by their intersecting are integrally formed, and the meshes 5 formed by it are on the same plane. ...

Abstract
The invention discloses a non-woven watermark net for obtaining a high-definition watermark and a manufacturing method of the watermark net. The watermark net is a nickel-made watermark net which is made of nickel and is of a flat net structure formed in an electroplating manner; upper and lower end faces of a plurality of nickel wires which are vertically and horizontally distributed in the nickel-made watermark net are on the same plane and bonding points which are formed by mutually crossing the upper and lower end faces are molded to form a whole body; formed net holes are located on the same plane. According to the non-woven watermark net, the nickel-made watermark net is produced by adopting the electroplating manner; the suitable strength and toughness and the corrosion resistance are met when a watermark net cage is manufactured; the thickness of the nickel-made watermark net is smaller than that of a copper net woven under the same quantity and the dehydration effect is better; the diameter of net wires is small and the toughness of the net wires is good so that a pattern level reflected by a watermark plate can be really reappeared on a nickel net, and furthermore, the definition of the watermark is improved.
Description
technical field [0001] The invention belongs to the technical field of watermark anti-counterfeiting, in particular to a non-woven watermark net for obtaining high-definition watermarks and a method for making the watermark net. Background technique [0002] At present, many paper mills in China have the ability to produce watermark anti-counterfeiting paper, and the watermark net used in the production of watermark paper is a copper net 2 formed by weaving copper wire 1 through warp and weft, such as figure 1 shown. Due to the high toughness of copper, the diameter of the copper wire needs to reach a certain value to ensure that it meets the tensile strength of the papermaking; on the other hand, due to the dehydration of the papermaking, the number of copper meshes cannot be increased infinitely. The production of watermark paper can only use a copper mesh with a suitable mesh, resulting in a large diameter of copper wire and a large thickness of the copper mesh, which ca...
