Embodiment

[0039] A kind of production method of environment-friendly Argentinian corrugated wax to imitate cordovan, is characterized in that: comprises the following steps:

[0040] (1) Choose 16-18 feet of Argentine blue leather, put it into the water squeezer and squeeze water until the moisture content is 20-22%, flatten and cut it to a thickness of 1.3cm, then cut and trim it to 12-14 feet, weigh the blue the weight of the hide;

[0041] (2) Put the weighed blue skin in 100 parts by weight in the drum, add 200 parts of water at 45°C, 0.35 parts of formic acid, 1.5 parts of rehumidifying agent MPC (Sitton Chemical), 0.3 parts of rehumidifying agent Wet agent SAF (Derui Chemical), rotate for 60min, adjust the pH value to 3.3-3.5, then add 2 parts of oxalic acid, 5 parts of industrial salt, 1.5 parts of acid enzyme PK568C (Lanxess Chemical), rotate for 180min, adjust the pH value to 2.5-2.8, drain, wash, change water;

[0042] (3) Add 80 parts of water at 30°C, 2 parts of neutralize...

Abstract

The invention relates to the technical field of leather, and provides a manufacturing method of environment-friendly imitated Cordovan leather from Argentina crust through wax change. Argentina blue-wet leather is adopted as a raw material and subjected to following processing steps: wringing and shaving; rewetting and de-tanning; primary neutralizing; pre-filling; standing; primary fixing; secondary neutralizing; filling; fat liquoring; secondary fixing, color register, wax fixing and after-finishing. The prepared leather is fine and smooth in leather surface, heavy and firm in texture and transparent in surface, the effect of replacing the Cordovan leather can be achieved, the problem that the requirement of common consumers for high-grade leather is difficult to meet due to the fact that the Cordovan leather is high in price and limited in quantity is solved, meanwhile, the additional value of blue leather is increased, and remarkable economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a method for making environmentally friendly Argentinian leather embryo waxed to imitate cordovan. Background technique [0002] There is a part of the buttocks of equines with particularly thick skin and high fiber density. This part only accounts for one-eighth of the buttocks area. The leather made from this part is called Cordovan. Cordovan leather, also known as Cordovan leather, has almost no pores on the surface and has a texture like baby skin; the texture is particularly fine and elastic, and it is not easy to leave scars; and it will reflect light under the light , very luxurious. The production process of cordovan is complicated, and it takes at least six months for skilled craftsmen to tan a piece of cordovan. Therefore, cordovan is known as "the diamond in leather" and is a kind of top leather. Due to the cumbersome process of processing cordovan, the long cycle ti...
