Production method of anti-counterfeiting silk with anti-counterfeiting function, application of anti-counterfeiting silk and anti-counterfeiting detection method

Abstract

The invention discloses a production method of anti-counterfeiting silk with an anti-counterfeiting function, application of the anti-counterfeiting silk and an anti-counterfeiting detection method. The production method comprises the following steps: in a growth process of silkworms, adding an anti-counterfeiting tracking agent into food for feeding the silkworms to prepare composite food, feeding the silkworms, obtaining silkworm cocoons after cocooning of the silkworms, and preparing the anti-counterfeiting silk, wherein the anti-counterfeiting tracking agent is composed of barium oxide, strontium oxide, aluminum oxide and zinc oxide, and a fixed feeding mass ratio among the barium element content, the strontium element content, the aluminum element content and the zinc element content in the composite food is controlled. The invention also discloses anti-counterfeiting application of the prepared anti-counterfeiting silk in paper money, passports, anti-uncovering labels, securities, stamps, identity cards and textile fabric, and a detection method of the anti-counterfeiting silk. According to the method for preparing the anti-counterfeiting silk with the anti-counterfeiting function, the operation is simple, the anti-counterfeiting strength is strong, the anti-counterfeiting silk has memory tracking and recognition functions, the mechanical property of the silk cannot be damaged, and the anti-counterfeiting silk can be applied and popularized on a large scale.

Description

technical field [0001] The invention belongs to the field of silk, and in particular relates to silk with anti-counterfeit function, in particular to a production method of anti-counterfeit silk with anti-counterfeit function, an application of anti-counterfeit silk and an anti-counterfeit detection method. Background technique [0002] Anti-counterfeiting marks have important practical applications and are closely related to our lives, involving items including banknotes, passports, tamper-evident labels, securities, stamps and ID cards, etc. Anti-counterfeiting marks can effectively curb forgery, greatly increase the difficulty and cost of forgery, or reduce the degree of simulation of forgery, and ultimately ensure the security and reliability of source file information. For example, the most common anti-counterfeiting chemical fiber, its anti-counterfeiting technology includes monochromatic optical fluorescent fiber, dual-band fluorescent fiber and multi-color segment dy...

Problems solved by technology

This scheme discloses a method that can set a layer of gold film on silk protein, and then conduct moisture absorption experiments based on the sensitivity of silk protein to humidity. However, although this anti-counterfeiting method uses silk protein and the changes after coating to achieve anti-counterfeiting, its process is more complicated and not It is conducive to the preparation of large-scale anti-counterfeiting silk, and it also needs to use more expensive gold as the film layer, which is not conducive to saving costs, but may also damage the silk, which will damage its mechanical properties in all aspects. At the same time, professional It is difficult to promote and use on a large scale
