Leather dye agent formula

Abstract

The invention relates to a leather dye formulation. The raw materials in the formulation are composed of 5-15% p-phenylenediamine, 1-5% aniline, 1-10% pigment, and 5-15% epoxy resin. , sodium chloride 3‑9%, ethylene glycol 2‑3%, water 1‑5%, hydrochloric acid 11‑19%, antiseptic and antifungal agent 5‑7%, fatty alcohol polyoxyethylene ether 3‑5%, glucose Sodium triacetate 3-5%, disodium aminotriacetate 3-9%, lauric acid diethanolamide 2-4%, the leather dye agent prepared by this method has no film-forming, non-sticking board, dull and bright, dyeing The back leather is not shiny, soft but not hard, thereby ensuring that the quality of the leather remains unchanged; in addition, the cost of the composition of the invention is low, and the production process is simple.

Description

Technical field [0001] The invention is a leather dye formulation. Background technique [0002] At present, most of the pigment-containing raw materials used in leather dyeing and finishing and leather maintenance in China contain anions. After use, the leather surface becomes hard, rubbery, seals the pores, and deteriorates air permeability. For example, the aniline leather will become Blackened, and the old leather has no effect after being colored. Suede and frosted leather can only be cleaned and cannot be colored. These raw materials are not widely used in China. The domestic leather industry mainly uses imported raw materials, but they are expensive. Costs have greatly increased, the prices of finished products in the market remain high, and sales have also been greatly affected. Summary of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a face color dye agent, which can make the leather non-filming, non-stick...

Problems solved by technology

[0002] At present, most of the pigmented raw materials used in my country's leather dyeing and finishing processing and leather maintenance contain anions. After use, the leather surface will become hard, gluey, seal pores, and air permeability will become poor. Blackened, imitation old leather has no old effect after coloring, suede and nubuck leather can only be washed but not colored. These materials are not widely used in China. The domestic leather industry mainly uses imported raw materials, but the price is expensive. The cost has increased greatly, the price of finished products in the market remains high, and the sales have also been greatly affected
