PROTECTIVE FIBRE, FORGERY-PROTECTED PAPER CONTAINING PROTECTIVE FIBRE AND METHOD FOR PRODUCTION THEREOF

摘要

FIELD: textile and paper.SUBSTANCE: invention relates to counterfeit protection and concerns anti-counterfeiting fibre (1), an anti-counterfeiting paper containing anti-counterfeiting fibre and a method of making same. Anti-counterfeiting fibre is a slice (4) or part of a slice cut along cross-section (3) of strip-shaped fibre (2), wherein strip-shaped fibre comprises a specific structure along length direction providing anti-counterfeiting characteristics.EFFECT: structures made using principles of present method have better orientation compared to existing structures of making protective fibres during paper manufacture and can create more unique optical characteristics.27 cl, 135 dwg, 13 ex
