Abstract

The invention relates to positioning distributed fiber anti-counterfeiting paper and a manufacturing method thereof, and belongs to the technical field of papermaking. The positioning distributed fiber anti-counterfeiting paper is characterized in that: anti-counterfeiting fibers are regularly distributed on the plane of the paper; the anti-counterfeiting fibers are positioned on one side of the paper; and in raised discontinuous rectangle or square, rhombus, roundness, ellipse, triangle, tetragon, polygon, sector or other irregular geometric pattern shape, the anti-counterfeiting fibers are plant fibers, chemical fibers, animal fibers, colored fibers or fluorescent fibers. The manufacturing method comprises the following steps of: 1) selecting the anti-counterfeiting fibers, and manufacturing a positioning distributed fiber mesh; 2) breaking; 3) pulping and regulating; 4) separating pulp; 5) forming paper; 6) squeezing and dehydrating; 7) drying; 8) applying the glue to the surface; and 9) calendering. The appearance of the paper has two-layer anti-counterfeiting measures of positioning distributed fiber anti-counterfeiting and geometric pattern anti-counterfeiting, the paper can be identified easily by the public, the anti-counterfeiting patterns are variable and high in production difficulty, and the anti-counterfeiting effect is good.

Description

1. Technical Field [0001] The invention relates to a positioning distribution fiber anti-counterfeiting paper and a manufacturing method thereof, and belongs to the technical field of papermaking. 2. Background technology [0002] Fiber anti-counterfeiting paper is widely used in anti-counterfeiting papers such as securities and product manuals, and the way of adding and distributing anti-counterfeiting silk in paper production is similar. Most of them are randomly distributed in paper. There are also individual reports of strip fibers. The production of anti-counterfeiting paper, but there is no patent or report about the positioning of anti-counterfeiting fibers in specific geometric patterns. For example, the positioning anti-counterfeiting yarn manufacturing method mentioned in the publication number CN1763312A patent, the product is positioned and continuously distributed anti-counterfeiting fiber yarns at a certain position of the paper banner, and other patents are mostly ...
