Title:
PRODUCTION METHOD FOR ANTI-COUNTERFEITING SILK HAVING ANTI-COUNTERFEITING FUNCTION, APPLICATION OF ANTI-COUNTERFEITING SILK, AND ANTI-COUNTERFEITING DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/104346
Kind Code:
A1
Abstract:
A production method for an anti-counterfeiting silk having an anti-counterfeiting function, application of the anti-counterfeiting silk, and an anti-counterfeiting detection method, comprising: in the growth process of silkworms, adding an anti-counterfeiting tracking agent to food provided for the silkworms to prepare composite food, feeding the silkworms with the composite food, and obtaining silkworm cocoons after silkworm cocooning, thereby preparing the anti-counterfeiting silk. The anti-counterfeiting tracking agent consists of barium oxide, strontium oxide, aluminum oxide, and zinc oxide; the content of a barium element, a strontium element, an aluminum element, and a zinc element in the composite food is controlled to have a fixed feeding mass ratio. Also disclosed are anti-counterfeiting application of the anti-counterfeiting silk in paper money, passports, tamper evident labels, securities, stamps, identification cards, and textiles, and the anti-counterfeiting detection method. The production method for the anti-counterfeiting silk having the anti-counterfeiting function is simple in operation and high in anti-counterfeiting strength, the produced anti-counterfeiting silk has memory tracking and identification functions, mechanical properties of the silk are not damaged, and large-scale popularization and application can be realized.
