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, and specifically relates to a leather processing method for Russian sturgeon skin. The applicant aims at that the Russian sturgeon is different from other species of sturgeon in that its bone pattern is denser and richer than other species of sturgeon, and its surface is densely covered. For the problems of small bony spurs, difficult processing and high equipment requirements, a processing method for Russian sturgeon leather is provided. After tanning, the Russian sturgeon leather is soft, plump, and the bone plate is intact. The high-quality rate of Russian sturgeon leather reaches More than 90%, greatly exceeding the 30% yield of traditional tanning methods.
