Description

Anti-counterfeiting method for chemical fiber textile production chain Technical field

The invention belongs to the anti-counterfeiting field of chemical fiber textile technology, and specifically relates to an anti-counterfeiting method of a chemical fiber textile production chain.

Background technique

At present, the anti-counterfeiting of textiles made of chemical fibers (chemical fiber textiles for short) is mainly carried out by using fibers with anti-counterfeiting functions, but at present, anti-counterfeiting chemical fibers are mainly monochromatic fluorescent fibers, dual-band fluorescent fibers and multi-color dyeing Fiber, photochromic, infrared absorption anti-counterfeiting products have also appeared one after another, such as Chinese patents CN2731620Y, CN103850144B, CN104963241B. With the continuous advancement of science and technology, the anti-counterfeiting features of monochromatic fluorescent fibers and dual-band fluorescent fibers are relatively simple and easy to forge, and their anti-counterfeiting strength can no longer adapt to high-end security fields such as banknotes and passports; multi-color dyed fibers are more stable It is a colored fluorescent fiber with poor concealment of anti-counterfeiting features, and is not suitable for high-end security fields such as banknotes and passports; photochromic and infrared absorption, easy to forge, but also susceptible to interference from other substances.

On the other hand, it also has the defect of insufficient anti-counterfeiting strength and is easy to be used. Imitation and forgery, it is difficult to have memory tracking properties.

At the same time, the above anti-counterfeiting methods for chemical fiber or chemical fiber textiles are difficult to trace the source of production. Especially for chemical fiber textiles, the production chain roughly includes the following stages: preparing element masterbatch or preparing element mother liquor, preparing chemical fiber, and dyeing yarn The existing anti-counterfeiting methods can only detect whether the final product contains anti-counterfeiting fibers to determine the authenticity. It is difficult to separately anti-counterfeit tracking the entire production process of chemical fiber textiles, that is, when any process in the production chain When chemical fiber products, dyes, and coatings that are not specified by the manufacturer are used, it is difficult for customers to trace the source, which may have a potential impact on the final quality of the product and the brand effect.
