Leather staining agent

Abstract

The invention relates to the technical field of staining agents, particularly a leather staining agent which comprises the following components in parts by mass: 25-36 parts of sulfitated triphenylmethane fuel, 3.6-4.8 parts of fatty alcohol polyethenoxy ether, 2.1-4.3 parts of sodium gluconate, 3-9 parts of disodium aminotriacetate, 1.2-3.5 parts of lauroyl diethanolamide, 4-11 parts of organic silicone oil and 3.6-6.2 parts of ethyl acetate. By adopting the formula, the leather staining agent can not form a film or adhere to the plate, and is lightless and bright. The stained leather is opaque, soft and non-hardening, thereby ensuring the leather quality unchanged. Besides, the leather staining agent has the advantages of low component cost and simple production technique.

technical field [0001] The invention relates to the technical field of dyeing agents, in particular to a leather dyeing agent. Background technique [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 has remained high, and sales have also been greatly affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leather dyeing agent with good dyeing effect and low cost...
