Embodiment 1

[0026] A leather production process, specifically comprising the following steps:

[0027] S1. Material selection: select animal fur, and place fur with similar thickness in the same drum for processing;

[0028] S2. Soaking solution: add an appropriate amount of leather soaking solution to the above-mentioned S1 drum to restore the fur to the state of fresh skin, and at the same time improve the bactericidal and anti-oxidative properties of the fur;

[0029] S3. Hair removal and degreasing: remove the rich oil in the cells of the above-mentioned S2 fur and the hair on the surface of the original hide to expose the natural and fine grain surface;

[0030] S4. Heating tanning: place the leather in S3 above in a chromium sulfate solution, and heat in a heating box at a heating temperature of 35° C., drying time of 30 minutes, and the pH value of the chromium sulfate solution is 4;

[0031] S5. Drying: place the leather obtained in the above S4 in a drying oven for drying at a d...

Abstract

The invention discloses a leather production process. The leather production process comprises the following steps of (1), material selection, specifically, animal furs are selected, and the furs of the similar thickness are placed in the same drum to be processed; (2), immersion with liquid, specifically, a proper amount of leather immersion liquid is added into the drum in the above step, the furs are made to recover to the fresh fur state, and meanwhile sterilization and inoxidizability of the furs can be improved. The leather immersion liquid contains a leaching agent, a sterilizing agent, an antioxidant and a degreaser, when moisture enters the furs under the action of the leaching agent, the sterilizing agent and the antioxidant can be carried into the furs, the inoxidizability and sterilizing effect of the leather are improved, the degreaser can remove oil stains on the surface layers of the furs, convenience is brought to full-filling of a coating in a subsequent process, the moisture is controlled to be 15-30 degrees, the leaching effect of the leather immersion liquid at the temperature can be the optimal, and the inoxidizability and sterilizing effect of the leather are promoted.

Description

technical field [0001] The invention relates to the technical field of leather production, in particular to a leather production process. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space, and has a special grain layer on its surface, which has natural grain and luster, and feels comfortable, so it is widely used by people. However, the leather in the prior art The processing technology is relatively chaotic, the quality of the processed leather is poor, and the production cost is high, and the durability of various leather products made with it is poor, which cannot meet the needs of consumers. Contents of the invention [0003] The present invention overcomes the above-mentioned shortcomings in the prior art, and provides a leather production process, which uses PP polyest...
