Abstract
The invention discloses a method for manufacturing vegetable-tanned cattle apron leather. Fish oil is added in the vegetable-tanned cattle apron leather manufactured through the method so that the fat content of the leather can be more sufficient, and the leather is washed with hot water for 10 min so that leather bleaching can be more thorough, wherein the water temperature ranges from 45 DEG C to 50 DEG C. The vegetable-tanned cattle apron leather manufactured through the method has the beneficial effects of being high in water absorption capacity and high in plasticity and has very good market prospects.
Description
Technical field
The present invention relates to field of leather and in particular to be a kind of manufacture vegetable tanning cattle apron leather method.
Background technology
Leather is through losing hair or feathers and the not perishable animal of degeneration obtained by the physics such as tanning, chemical process
Skin.Leather is made up of in three dimensions close weave natural protein fibre, and its surface has a kind of special
Grain layer, has natural graining and gloss, comfortable feel.Vegetable tanning, is a kind of technique name processing raw hide
Claim.Take off not skin through processing and be referred to as rawhide or raw hide it is simply that skin with animal, undressed
Rawhide can rot.Raw hide after PROCESS FOR TREATMENT is referred to as removing from office.With the vegetable tanning agent (pellet extracting in plant
The polyphenol compounds such as thujic acid liquid, plant polyphenol) tanning first layer lether out referred to as vegetable tanning Corii Bovis seu Bubali, generally
Corii Bovis seu Bubali.The leather of vegetable tanning agent (tannin acid solution) tanning because water absorbing force is strong, plasticity is high, be easy to integer,
It is very suitable for engraving and skin is moulded.
Content of the invention
The present invention provides a kind of method manufacturing vegetable tanning cattle apron leather, for realizing the purpose of the present invention, this
Bright technical scheme is as follows：
A kind of manufacture vegetable tanning cattle apron leather method, raw material include akali sulphide, help soft dose, Caustic soda, Calx,
Calcium chloride, bleaching powder, ammonium sulfate, penta sodium pentachlorophenate, syntans, myrica extract, larch extract, fish
Oil, Adeps Bovis seu Bubali, its concrete steps includes：
(1) rotary drum immersion
Put into cattle hide toward in rotary drum, add and help soft dose and Caustic soda, turn per hour 10 minutes, rotate 4 hours,
Then continuously turn again 4 hours, add Caustic soda and bleaching powder, continuously rotate 12～13 hours；
(2) fleshing, cut edge
Wash 40min with flowing water after taking-up, then skin is carried out with fleshing, cut edge is processed, the piece skin thickness after process
For 5.5-6 millimeter；
(3) rolling alkali depilation
Add akali sulphide, Calx in rotary drum, then put into skin, rotate 1-2h, stop 1h, then turn 1h to stop
1h, then flame enrichment alkali, later every 1h that turns stops 1h, amounts to and rotates 12-24h, abandons liquid, flowing water washes 40-60min,
Stay the water of 10%-20%, add 1% calcium chloride to turn 3-5min, go out drum；
(4) deliming
Skin is weighed, flowing water washes 45-60min, then washes 2.5-3h with 2.4% ammonium sulfate；
(5) vegetable tanning
Add penta sodium pentachlorophenate in rotary drum, then adjust pH to 4-4.4 with syntans, stir well；
(6) drum tan tempering
Leather jacket enters to mix up in the drum of PH, pours myrica extract into, turns 1-2h, adds larch extract and synthesis
Tanning agent, turns 8-9h, stops drum overnight, and the skin after drum tan is put in the tannic extract pond of 70-75 Either degree, every two days
A skin, went out skin after 10 days；
(7) float skin
Add purificant in drum, turn 20-30min, then skin flowing water washes 3-4h, water squeezing, weigh；
(8) stuffing
Coat Adeps Bovis seu Bubali 3%-5% in epidermis face, hang at ambient temperature and dry in the air 35 DEG C, stand 14-16h, use plastics
Cloth covers；
(9) it is dried
In temperature is for 30-38 DEG C of drying machine, tiling is banked up and 5-8h is dried, take out standing 1-2 after being dried
My god, finished product.
Preferably, use hot water wash 10min of water temperature 45-50 DEG C after flowing water is washed in step (7) again.
Preferably, add fish oil 1.5%-2% in step (8).
Beneficial effect：The invention provides a kind of method manufacturing vegetable tanning cattle apron leather, using our legal system
The method of the vegetable tanning cattle apron leather made adds fish oil makes the fat content of skin more sufficient, uses water temperature 45-50
DEG C hot water wash 10min drift skin can be made more thorough, using this method manufacture vegetable tanning cattle apron leather tool
Have the advantages that water absorbing force is strong, plasticity is high, there is good market prospect.
