The present application relates to a kind of anti-fake silk composite sewing thread and preparation method thereof, belong to sewing thread technical field.The present application uses natural fluorescent dye (sanguinarine, berberine) and protein fluorescent dye (red fluorescent protein, enhanced yellow fluorescent protein) to carry out combination dyeing to silk, through the differentiation of the fineness and length design to dyed silk, natural fluorescent dye dyed silk uses relatively thick fineness and relatively long cut length, protein fluorescent dye dyed silk uses relatively thin fineness and relatively short cut length, so that the obtained fiber can present the characteristic color light of intensity, hue different under different color light excitation, and then combine fluorescence characteristics, silk length, silk fineness multiple detection dimension constructs multiscale composite anti-fake system.

The application provides a preparation method of a natural product 6-HHS, which comprises the following steps: reacting a compound 1, sanguinare, with vinylmagnesium bromide to prepare a compound 2; and reacting the compound 2 with borane tetrahydrofuran complex to prepare 6-HHS. The application uses sanguinare as a raw material to prepare the natural product 6-HHS, has a short synthesis route, high synthesis efficiency, a yield of each step is more than 85%, the comprehensive yield of the natural product 6-HHS can reach 76%, and the operation is simple, the purity is high, and the application can provide a simple and efficient way for chemical synthesis of 6-HHS.
