Problems solved by technology

[0004] However, due to the advancement of industry, people's requirements for leather quality and production efficiency have also increased. The mechanized leather products on the market already have the characteristics of excellent performance, novel styles and rich colors. However, due to the limitation of processing technology, modern mechanization Processed leather products usually have no obvious difference in appearance and feel in terms of style and tone. Traditional leather tanning methods have been gradually eliminated due to their own limitations, and have even appeared on the verge of extinction.

Embodiment 1

[0023] The method for processing leather with livestock dung comprises the steps of:

[0024] 1) Choose flat raw hides, dry the raw hides in the sun to remove oil until no oil seeps out, and then air-dry;

[0025] 2) Soak the air-dried rawhide in a mixture of whey and salt at a volume ratio of 3:7 for 7 days, take out the dried water, and obtain cooked hide;

[0026] 3) Evenly smear solidified yogurt on the surface of the cooked skin, lay it flat and dry it under natural light for 2 days, then embed the cooked skin in soil with a water content of 75% to soften;

[0027] 4) Take out the softened cooked skin and knead until it is completely soft, then polish it with iron;

[0028] 5) Put the polished cooked leather on the livestock manure and bake for 45 minutes to obtain the leather.

Embodiment 2

[0030] The method for processing leather with livestock dung comprises the steps of:

[0031] 1) Choose flat raw hides, dry the raw hides in the sun to remove oil until no oil seeps out, and then air-dry;

[0032] 2) Soak the air-dried rawhide in a mixture of whey and salt at a volume ratio of 3:7 for 7 days, take out the dried water, and obtain cooked hide;

[0033] 3) Evenly smear solidified yogurt on the surface of the cooked skin, spread it flat and dry it under natural light for 1 day, then embed the cooked skin in soil with a water content of 60% to soften;

[0034] 4) Take out the softened cooked skin and knead until it is completely soft, then polish it with iron;

[0035] 5) Put the polished cooked leather on the livestock manure and bake for 40 minutes to obtain the leather.

Embodiment 3

[0037] The method for processing leather with livestock dung comprises the steps of:

[0038] 1) Select flat raw hides for depilation treatment, and air-dry the depilated raw hides under natural light to remove oil until no grease seeps out;

[0039] 2) Soak the air-dried rawhide in a mixture of whey and salt at a volume ratio of 4:7 for 10 days, take out the water and dry it to obtain cooked hide;

[0040] 3) Evenly smear solidified yogurt on the surface of the cooked skin, spread it flat and dry it under natural light for 2 days, then embed the cooked skin in soil with a water content of 80% to soften;

[0041] 4) Take out the softened cooked skin and knead until it is completely soft, then polish it with iron;

[0042] 5) Put the polished cooked leather on the livestock manure and bake for 60 minutes to obtain the leather.

Abstract

The invention discloses a method for processing leather by using livestock manure and belongs to the field of leather processing. The method comprises the following steps of: selecting flat raw hide; drying the raw hide under natural light to remove oil until no grease seeps, and airing the raw hide; soaking the raw hide in a tanning solution, airing the raw hide, applying yoghurt onto the raw hide; flatly spreading the raw hide under natural light to air; burying the raw hide in soil to soften the raw hide; taking out and rubbing the softened leather until the leather is completely soft; polishing the leather with an iron device; and baking the leather on livestock excrement to obtain a finished product. The leather tanning technology is improved on the basis of a traditional leather tanning technology, the obtained leather has rich color difference and various texture textures, the individual requirements of consumers for pursuit for novelty and change are better met, and the quality of leather products is also better improved.

Description

technical field [0001] The invention relates to a leather processing method, in particular to a method for processing leather by using livestock manure, and belongs to the field of leather processing. Background technique [0002] Leather is a kind of fabric that can be used to make clothes, leather shoes and other products. The leather industry is closely related to human life and the development of the national economy, and is a pillar industry of light industry. [0003] The traditional leather tanning process is to soak the raw hide in clean water for 4 to 5 hours, then scrape off the residual meat and dirt attached to the skin with a knife, then put it in warm alkaline water, wash it with a brush, and then wash it with alum. (that is, alum), salt, and water are formulated into a tanning stock solution in a ratio of 3:1:6, and 1 part of the stock solution to 7 parts of water is placed in a basin to immerse the animal hide, and the cooked animal hide is soaked in the tann...
