A method for preparing a novel waterborne polyurethane foam layer for synthetic leather is disclosed. The method includes first preparing a charged cellulose nanofiber by using a wood pulp as a raw material; meanwhile, subjecting a polyisocyanate, a macromolecular diol, a hydrophilic chain extender and a small molecular chain extender to a polyaddition reaction and an acid-base neutralization reaction in sequence, to obtain a cationic or anionic waterborne polyurethane; adding the charged cellulose nanofiber and a certain amount of a crosslinking agent to the oppositely charged ionic waterborne polyurethane emulsion, stirring the resulting mixture, forming a bimolecular layer at the gas/liquid interface by a self-assembly of the cellulose nanofiber and waterborne polyurethane nanoparticles through electrostatic interactions to obtain a stable Pickering foam; using the stable Pickering foam as a template, drying and solidifying to obtain the waterborne polyurethane foam layer for synthetic leather.

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.
