Abstract

The invention discloses an anti-counterfeiting fiber and a manufacturing method thereof as well as safety paper using the anti-counterfeiting fiber and a safety article. The anti-counterfeiting fiber has a multilayered structure in the length direction, wherein any two adjacent layers of the multilayered structure are fixedly combined and at least one layer has chemical components which are different from those of the adjacent layer; at least one layer contains additives with anti-counterfeiting information. The manufacturing method comprises the following steps: firstly, manufacturing a sheet material with the multilayered structure in the thickness direction; machining the sheet material into the anti-counterfeiting fiber with the multilayered structure in the length direction through a cutting manner. The safety paper and the safety article using the anti-counterfeiting fiber and the safety article manufactured by the safety paper adopt counterfeiting methods including printing and the like and the anti-counterfeiting characteristics of the anti-counterfeiting fiber do not occur, so that the anti-counterfeiting capability is improved.

Description

technical field

[0001] The invention relates to an anti-counterfeiting fiber and a manufacturing method thereof, in particular to an anti-counterfeiting fiber with a multi-layer structure and a manufacturing method thereof. Background technique

[0002] Security objects, such as banknotes, securities or the like, need to be provided with specific security features in order to prevent counterfeiting and to verify their authenticity. It is a known technology to use anti-counterfeiting fibers as the anti-counterfeiting features of banknotes and securities. They are generally composed of short organic synthetic polymers and cotton fibers, and are introduced into paper during papermaking.

[0003] Anti-counterfeiting fibers with a single structure in the length direction and anti-counterfeiting fibers with a single anti-counterfeiting feature have been widely used in anti-counterfeiting papers such as banknote paper, bond paper, and bill paper, but paper containing this type of a...
