Problems solved by technology

[0004] The above-mentioned anti-counterfeiting fiber has a certain anti-counterfeiting effect, and is suitable for use in certain environments, but the anti-counterfeiting feature is too single, the anti-counterfeiting concealment is not good, it is easy to be copied, and the anti-counterfeiting feature is easily destroyed, so it needs a high degree of anti-counterfeiting and concealment. Good anti-counterfeiting methods are used in fiber production

Abstract

The invention relates to a preparation method of an anti-counterfeiting viscose fiber. The preparation method comprises the following steps of dipping pulp in an aqueous solution of alkali, squeezing,crushing, aging, cooling, sulfonating, and dissolving in a dilute alkali solution to obtain a crude viscose; uniformly mixing the crude viscose with various amino acid metal chelates, and carrying out defoaming and ripening to obtain a spinning stock solution; carrying out wet spinning and acid bath on the spinning stock solution, and then carrying out drafting, cutting, refining, oiling and drying treatment to obtain the anti-counterfeiting viscose fiber, wherein the sum of the mass of metal elements contained in the amino acid metal chelates accounts for 0.03-0.11% of the mass fraction of the anti-counterfeiting viscose fiber. The anti-counterfeiting viscose fiber disclosed by the invention is subjected to anti-counterfeiting encryption treatment by utilizing various amino acid metal chelates, and anti-counterfeiting identification is carried out by detecting and encoding metal elements and amino acid types, so that the anti-counterfeiting degree is high, and the anti-counterfeitingconcealment is good.

Description

technical field [0001] The invention relates to an anti-counterfeit fiber, in particular to an anti-counterfeit viscose fiber, a preparation method and an anti-counterfeit method. Background technique [0002] With the development and progress of society, chemical fibers have become an indispensable part of human life, and the anti-counterfeiting identification of chemical fibers has gradually become important. At present, the anti-counterfeiting of chemical fibers is mainly realized by monochromatic fluorescent fibers, but the anti-counterfeiting features are single. , easy to forge, and not concealed. [0003] Chinese patent CN110042490A discloses a viscose fiber containing a tracer mark and a preparation method thereof. The rare earth metal chelate is used as a tracer, and the tracer dispersion is mixed with the spinning viscose collagen solution to make a viscose fiber containing a tracer. Viscose staple fiber marked with tracer; Chinese patent CN111394822A discloses a ...
