Embodiment 1

[0037] The chrome-tanned leather production process of sturgeon skin in the present embodiment comprises the following steps successively;

[0038] Soaking in water: Soak the sturgeon skin to be treated in the soaking solution, which contains 300% water, 1% penetrating agent such as JFC, 1% degreasing agent, 0.15% fungicide such as KL, 1% sodium carbonate, soak The time is overnight.

[0039] Manual de-fleshing: Check the condition of the sturgeon skin on the second day after soaking in water, and manually de-flesh after fully softening, that is, remove the remaining fish meat on the surface of the sturgeon skin by manual de-fleshing, and weigh it. Strengthen the fleshing of the back and flanks, but at the same time, care should be taken to protect the natural scales from falling off.

[0040] Degreasing: Put the de-fleshed sturgeon skin into a degreasing solution with a temperature between 35 and 40°C. The degreasing solution contains 250% water, 3% degreasing agent, and 3% ...

Embodiment 2

[0056] The chrome-tanned leather production process of sturgeon skin in the present embodiment comprises the following steps successively;

[0057] Soaking in water: Soak the sturgeon skin to be treated in the soaking solution, which contains 200% water, 1% penetrant, 0.5% bactericide, and 2% sodium carbonate, and the soaking time is overnight.

[0058] Flesh removal: Check the condition of the sturgeon skin on the second day after the water immersion treatment, and manually remove the flesh after it is fully softened, that is, remove the remaining fish meat on the surface of the sturgeon skin by manually removing the flesh, weigh it, and strengthen it while removing the flesh. The flesh on the back and sides should be removed, but at the same time, care should be taken to protect the natural scales from falling off.

[0059] Degreasing: Put the de-fleshed sturgeon skin into a degreasing solution with a temperature between 35 and 40°C. The degreasing solution contains 200% wat...

Embodiment 3

[0075] The chrome-tanned leather production process of sturgeon skin in the present embodiment comprises the following steps successively;

[0076] Soaking in water: Soak the sturgeon skin to be treated in the soaking solution, which contains 400% water, 3% penetrating agent such as JFC, 2% degreasing agent, 0.1% fungicide such as KL, 2.5% sodium carbonate, soak The time is overnight.

[0077] Flesh removal: Check the condition of the sturgeon skin on the second day after the water immersion treatment, remove the flesh after fully softening, that is, manually remove the remaining fish flesh on the surface of the sturgeon skin, weigh it, and strengthen the back while removing the flesh The meat of the head and sides of the abdomen should be removed, but at the same time, care should be taken to protect the natural scales from falling off.

[0078] Degreasing: Put the de-fleshed sturgeon skin into a degreasing solution with a temperature between 35 and 40°C. The degreasing solu...

Abstract

The invention discloses a sturgeon skin chrome tanning leather production process, which comprises the following steps: immersing in water; removing meat manually; degreasing; scraping oil slick; liming; scraping oil slick; liming again; scraping oil slick; deliming and softening; bleaching by oxidization; pickling; bleaching by reduction; chrome tanning; dyeing and greasing; re-tanning; washing; hanging and drying; and coating. In the invention, when the sturgeon skin chrome tanning leather production is adopted, the grease content in the sturgeon skin can be reduced obviously and the color of particle surface of the back of the sturgeon skin can be lightened; and thus, dyeing or production of light leather can be facilitated, the finished leather retains the natural attractive scales and special textures of sturgeon skin, the utilization value of the sturgeon skin is improved greatly, and the added value of the product is increased obviously.

Description

technical field [0001] The invention relates to a leather processing technology, in particular to a chrome-tanned leather production technology of sturgeon skin. Background technique [0002] Sturgeon is a national first-class protected animal and lived in the same era as dinosaurs, so it has high research value. In recent years, with the continuous development of the technology of artificially breeding sturgeon, relevant research has been done on the edible value of sturgeon at home and abroad. [0003] The whole body of sturgeon is a treasure: fish bones contain anti-cancer factors, which can inhibit the division of cancer cells and play a role in health care; fish meat has the functions of beauty, skin care, lowering blood pressure and blood lipids, strengthening the brain, nourishing the kidney, etc.; caviar contains high protein, It is extremely nutritious; cod liver and its internal organs can also be made into exquisite food. [0004] Although sturgeon has a high ed...
