1. A method for preparing an anti-counterfeiting modal fiber, comprising steps of:
(1) mixing a pulp stock solution with a cellulose catalyst, alkalizing, aging, sulfonating, and then dissolving the pulp stock solution in an alkaline solution to obtain a treatment solution; and
(2) mixing the treatment solution uniformly with a plurality of amino acid-metal chelates, filtering, defoaming and ripening to obtain a spinning stock solution; and mixing the spinning stock solution uniformly with a spinning bath additive, and wet spinning, followed by post-treatments, to obtain the anti-counterfeiting modal fiber, wherein the amino acid metal-chelates account for 0.5%-1.5% by weight of the spinning stock solution.
