Problems solved by technology

With the continuous advancement of science and technology, the anti-counterfeiting features of single-color fluorescent fibers and dual-band fluorescent fibers are relatively simple and easy to forge, and their anti-counterfeiting strength cannot adapt to high-end security fields such as banknotes and passports; Poor, and it is a colored fluorescent fiber, the anti-counterfeiting feature is poorly concealed, and it is not suitable for high-end security fields such as banknotes and passports; photochromic and infrared absorption are easy to forge and are also susceptible to interference from other substances
[0003] At present, someone has also proposed a method for preparing marked cellulose fibers-CN101942707B, which discloses a dispersion liquid added in the preparation process of cellulose fibers. The dispersion liquid includes a metal-inorganic compound, a dispersant and water. The agent is fatty alcohol polyoxyethylene phosphate, sodium hexametaphosphate, nonylphenol polyoxyethylene ether, sodium polyacrylate or sodium butylnaphthalene sulfonate; it is determined by comparing the retention and addition of metal inorganic compounds in the fiber Judging, distinguishing and identifying textiles; however, on the one hand, it also has the defect of insufficient anti-counterfeiting, it is easy to be imitated and forged, and it is difficult to have memory tracking properties; on the other hand, the dispersion mentioned in it is only suitable for use in the preparation of cellulose fibers , it is difficult to apply in the anti-counterfeiting of chemical fiber

Abstract

The invention discloses an anti-counterfeit method for chemical fiber textiles, which comprises: using anti-counterfeit chemical fibers to make chemical fiber textiles, and performing element detection on the chemical fiber textiles; raw materials for anti-counterfeit chemical fibers include fiber-forming high polymers, and elements selected from One of the elemental masterbatches; the elemental masterbatch contains the first anti-counterfeiting tracking agent, and the elemental masterbatch includes the second anti-counterfeiting tracking agent; the two are composed of at least two metal oxides respectively, and the metal elements contained in various metal oxides are controlled There is a fixed feeding mass ratio between the contents, and the metal oxide is barium oxide, zinc oxide, molybdenum trioxide, zirconium dioxide, aluminum oxide, calcium oxide, strontium oxide, germanium dioxide or vanadium pentoxide; the present invention Using specific anti-counterfeiting chemical fibers to make chemical fiber textiles, and then testing them is to detect specific anti-counterfeiting chemical fibers, which can give chemical fiber textiles sufficient distinction from other types, so as to realize the anti-counterfeiting identification of chemical fiber textiles.

Description

technical field [0001] The invention belongs to the anti-counterfeiting field of chemical fiber textiles, in particular to an anti-counterfeiting method of chemical fiber textiles. Background technique [0002] At present, the anti-counterfeiting of textiles made of chemical fibers (referred to as chemical fiber textiles) is mainly carried out by using fibers with anti-counterfeiting functions, but the current anti-counterfeiting chemical fibers are mainly monochromatic fluorescent fibers, dual-band fluorescent fibers and multi-color dyed fibers. , photochromic, infrared absorption anti-counterfeiting and other products have also appeared, such as Chinese patents CN2731620Y, CN103850144B, CN104963241B. With the continuous advancement of science and technology, the anti-counterfeiting features of single-color fluorescent fibers and dual-band fluorescent fibers are relatively simple and easy to forge, and their anti-counterfeiting strength cannot adapt to high-end security fie...
