Description
Technical field
The present invention relates to the making of buffalo hide upper leather, and in particular to the method for production buffalo hide upper leather.
Background technology
The market potential of leather and leather products is very big, and global leather aggregate demand is about 1.0 hundred million square metres, is equivalent to
The yield of 300000000 ox-hides (standard skin), Chinese leather yield convert into nearly 70,000,000 of standard skin, account for about global leather yield
23.33%.Buffalo line soft leather is using buffalo hide as raw material, and production keeps the soft leather of its natural graining, mainly for the manufacture of
Medium and high-grade leather goods, leather shoes product.
In the prior art, there are buffalo hide fleece is sparse, grain is coarse, has apparent papillaris pars protrusion and corrugation, depilation is not
Just, it is inefficient.
Invention content
The present invention solves that buffalo hide fleece of the existing technology is sparse, and grain is coarse, have apparent papillaris pars protrusion and
Corrugation, depilation is inconvenient, it is inefficient the problem of, method that production buffalo hide upper leather is provided, during application can low cost and
The subsidiary dirt of buffalo hide raw material is quickly cleaned up, depilation depilation is neat and tidy, and convenient and efficient, buffalo hide raw material surface is put down
Frontlighting is slided, and color and luster is soft and bright, and cutting rate is good, and tensile strength is high.
The present invention is achieved through the following technical solutions：
The method for producing buffalo hide upper leather, includes the following steps：A, buffalo hide is placed in rotary drum and adds water, added successively
Entering quick lime, sodium carbonate, osmosis type emulsifier Talnsol so that temperature is maintained at 20-30 DEG C, rotates rotary drum 30min, after
Each two hour rotates rotary drum 15min, and the time is 18-20 hours；B, buffalo hide is taken out into rotary drum, cleaned up, by vulcanized sodium,
Water presses 3-5：350 volume ratio mixing, obtained depilatory agent, will by depilatory agent by being sprayed at buffalo hide root of hair
Buffalo hide is sent at -4~-6 DEG C and freezes 20-25min, and buffalo hide is placed under room temperature and is thawed, and after fully thawing, is put into rotary drum
30~45 DEG C are heated to, rotates 20~35min of rotary drum, surface hair rinses are clean；It C, will depilation treated buffalo hide leaching
Yu Shuizhong with ultrasonication, adds in polyelectrolytes, the polymerization high score after ultrasonication 15s into water
The mass ratio of sub- electrolyte and buffalo hide is 1：1000；D, it takes out in buffalo hide merging rotary drum and adds in water, ammonium sulfate, ORAPON
OO macerating enzymes rotate 90~480 minutes, are washed after softening completely；E, buffalo hide is dried and done, then carry out mill skin processing, water
Ox-hide holding surface is smooth.The present invention reacts generation calcium hydroxide with water by adding in quick lime in water, and calcium hydroxide is strong
Alkali and water is slightly soluble in, calcium hydroxide insoluble in water reacts sodium reaction generation sodium hydroxide with carbonic acid, and sodium hydroxide is highly basic
And it is soluble in water, plasma protein can be more dissolved, the more non-collagen matter dissolved in skin plays the work for cleaning buffalo hide
With.Of low cost, simple and convenient, cleaning effect is good.The hair root of buffalo hide is sprayed onto using vulcanized sodium, by depilatory agent
Portion is heated by defrosting after freezing a period of time, passes through the principle expanded with heat and contract with cold so that the pore of root of hair becomes larger, and is convenient for
Hair comes off naturally after depilatory agent effect, and passes through rotary drum and carry out rotation help hair disengaging, and lose hair or feathers efficient quick.Pass through ultrasound
Wave processing replaces adding in swelling agent, simple to operate, and adds in polyelectrolytes after sonication and be conducive to
Further buffalo hide is cleaned, ensures that buffalo hide keeps elasticity good, hide flat transparent is moderate.By ammonium sulfate,
ORAPON OO macerating enzymes carry out sofening treatment to buffalo hide so that buffalo hide is soft.Mill skin processing is carried out to buffalo hide, can be led to
It crosses fine sandpaper or crocus cloth is polished so that the surface of buffalo hide is smooth, easy to process.
Further, the method for producing buffalo hide upper leather, water, quick lime, sodium carbonate, osmosis type breast in the step A
The mass ratio of agent Talnsol and buffalo hide is 160-190：0.2-0.3：0.2-0.3、0.3-0.4：80-100.
Further, the method for producing buffalo hide upper leather, ultrasonic frequency is 32-36kHz in the step C, ultrasound
Time is 20-25min.
Further, the method for producing buffalo hide upper leather, polyelectrolytes is birdsed of the same feather flock together for polybases in the step C
Close polyelectrolyte.As a kind of preferred embodiment, become cation high molecular after the ionization of polybases Type of Collective polyelectrolyte.
Compared with prior art, the present invention it has the following advantages and advantages：
1st, the present invention reacts generation calcium hydroxide with water by adding in quick lime in water, and calcium hydroxide is highly basic and slightly soluble
Yu Shui, calcium hydroxide insoluble in water react sodium reaction generation sodium hydroxide with carbonic acid, and sodium hydroxide is highly basic and is dissolved in water
In, plasma protein can be more dissolved, the more non-collagen matter dissolved in skin plays the role of cleaning buffalo hide.
2nd, the present invention is heated by defrosting after freezing a period of time, passes through the principle expanded with heat and contract with cold so that root of hair
Pore becomes larger, and hair comes off naturally after being acted on convenient for depilatory agent, and passes through rotary drum and carry out rotation help hair disengaging, and depilation is efficient
Fast.
3rd, the present invention replaces adding in swelling agent by ultrasonication, simple to operate, and adds after sonication
Enter polyelectrolytes to be conducive to further clean buffalo hide, ensure that buffalo hide keeps elasticity good, hide
Flat transparent is moderate.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiment, the present invention is made
Further to be described in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this
The restriction of invention.
