| titleOfInvention | Infrared traceability anti-counterfeiting method for down fibers |
| abstract | The invention discloses a down fiber tracing anti-counterfeiting method, belongs to the technical field of infrared anti-counterfeiting authentication, and particularly comprises an anti-counterfeiting method, an anti-counterfeiting material and a detection device of down fibers. Firstly, carrying out gamma-mercaptopropyltrimethoxysilane (MPTMS) coating and oxidation modification on a nano inorganic non-metallic material which is singly doped with Yb (ytterbium) or co-doped with various rare earth ions containing Yb (ytterbium) and the like and has characteristic infrared emission to obtain a nano sulfonated anti-counterfeiting material; soaking the washed down feather fibers into finishing liquid containing the anti-counterfeiting material, wherein the pH value of the finishing liquid is 3-4, adsorbing the negatively charged modified anti-counterfeiting material by the positively charged down feather fibers by utilizing the isoelectric point characteristics of down feather protein fibers, and combining the negatively charged modified anti-counterfeiting material and the negatively charged modified anti-counterfeiting material by utilizing coulomb force and hydrogen bond acting force to obtain the traceable down feather fibers with characteristic infrared emission; and the infrared characteristic spectrum of the down feather fibers is detected by using a detection device with corresponding transmitting and receiving diodes, so that the tracing authentication is realized. |
