摘要： The present invention provides a preparation method of an anti-counterfeiting lyocell fiber, including the following steps: dissolving at least one amino acid metal chelate and a cellulose pulp in an aqueous solution of a cellosolve to obtain a spinning solution, and then performing wet spinning using the spinning solution to obtain an anti-counterfeiting lyocell fiber, wherein the amino acid metal chelate account for 0.2% to 0.6% of the total mass of the anti-counterfeiting lyocell fiber. The anti-counterfeiting lyocell fiber of the present invention uses an amino acid metal chelate for encryption, and the process is simple. The prepared product can be provided with one or two passwords based on the ratio of metal ions and the amino acids, so that the product prepared from this fiber has the advantages of memory tracking properties, identification function and high anti-counterfeiting capability grade.
