Problems solved by technology

[0002] Russian sturgeon (A. gueldenstaedti) is different from other species of sturgeon. Its bone plate pattern is denser and richer than other species of sturgeon, and its surface is densely covered with small bony spurs. It is difficult to process and requires high equipment. The ordinary processing method is very difficult. Difficult to meet the needs of commercial production
From the retrieved information and published papers, there is no mature leather processing method for Russian sturgeon

Embodiment 1

[0052] A kind of Russian sturgeon skin leather processing method, comprises the steps:

[0053] According to conventional recognition in this field, the weight of the sturgeon skins involved in the present invention all refers to the wet weight of the sturgeon skins; benchmark.

[0054] 1) Pre-degreasing by soaking in water

[0055] (1) The water temperature is 18-22 degrees, fully wash the sturgeon skin, and weigh it after washing;

[0056] (2) take by weighing 200% water of the sturgeon skin weight that step (1) obtains, 1% soaking agent (BASF EusaponW), 1% bactericide (LANXESS CISMOLLAN AN 90), 1% degreaser (Brother Chemical Industry H900);

[0057] (3) Put the prepared sturgeon skin and water into the drum, keep the water temperature at 20-22 degrees Celsius, then add water soaking agent, bactericide, and degreasing agent, turn the drum for 15 minutes, stop for 45 minutes, 2 revolutions per minute, and automatically A total of 24 hours from the start of feeding to the en...

Abstract

The invention belongs to the field of leather processing, in particular to a Russian sturgeon skin leather processing method. The applicant provides the Russian sturgeon skin leather processing method, which aims at the problems that the Russian sturgeon skin leather is different from other sturgeon species, the bone plate pattern of the Russian sturgeon is denser and richer than other sturgeon species, the surface is densely covered with fine bone spurs, the processing difficulty is larger, and the equipment requirement is high. The tanned Russian sturgeon skin leather is soft, plump, and thebone plate is intact, and the high-quality product rate of the Russian sturgeon leather reaches more than 90%, greatly exceeding the yield of 30% of the traditional tanning method.

Description
