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) Select 16-18 feet of Argentine blue leather, put it into the water squeezer and squeeze water to 20-22% moisture content, smooth and evenly shave the thickness of 1.3cm, then cut and trim 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 neutralized tannin ...

Abstract

The invention relates to the technical field of leather, and provides an environment-friendly manufacturing method of Argentinian leather embryo waxed to imitate cordovan leather, which uses Argentine blue leather as a raw material and undergoes the following processes: squeezing water, smoothing → rewetting, detanning → once Neutralization→pre-filling→standstill→primary fixing→secondary neutralization→filling→fatliquor→secondary fixing→color registration→wax fixing→finishing. The prepared leather has a delicate leather surface, thick and solid texture, and a transparent surface, which can replace the effect of cordovan leather, and solve the problem that it is difficult to meet the needs of ordinary consumers for high-grade leather due to the high price and limited quantity of cordovan leather. At the same time, the added value of blue leather is increased, which has significant economic benefits.

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...
