Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of ox leather processing, acquisition
Ox-hide leather goods shiny appearance is natural.
To achieve the above object, the present invention provides the following technical scheme that
A kind of ox leather processing, it is characterised in that: include the following steps,
Step 1, cation slurry is sprayed on grain side of leather, equably sprays primary cation after drying again by spray cation
Slurry, drying；
Step 2, leather to be scalded, grain side of leather is put on the belt upward and is flattened using roll-in, the temperature of roller is 130 DEG C,
Pressure is 20-30kg；
Step 3, it falls soft, leather is put into and is fallen in soft rotary drum, soft 30h is fallen；
Step 4, leather is placed on to stretch tight on toggling machine and put down by toggling；
Step 5, grain side of leather is put on the belt upward and is flattened using roll-in by secondary boiling hot leather, and the temperature of roller is 130
DEG C, pressure 10-20kg；
Step 6, spray plane is starched, and starch adhesive liquid is equably sprayed on to the front of leather, sprays a starch adhesive after drying again, then dry
It is dry, spray third time, drying；
Step 7, light is sprayed, bright slurry is equably sprayed on to the front of leather, drying；
Step 8, leather is scalded three times, grain side of leather is put on the belt upward and is flattened using roll-in, and the temperature of roller is 135
DEG C, pressure 30-40kg；
Step 9, secondary to fall soft, leather is put into and is fallen in soft rotary drum, soft 60min is fallen；
Step 10, vacuum pattern absorbing carries out vacuum pattern absorbing 60s to leather with vacuum tattoo machine, and temperature is 80 DEG C.
Step 11, hand feeling agent is sprayed, by hand feeling agent even application in the front of leather, drying；
Step 12, grain side of leather is put on the belt upward and is flattened using roll-in by four boiling hot leather, and the temperature of roller is
130 DEG C, pressure 10-20kg；
According to parts by weight, the hand feeling agent includes following components:
By using above-mentioned technical proposal, carbon nanotube is added in hand feeling agent, after carbon nanotube is uniformly distributed, in ox
Leather surface forms slight convex, so that light generates certain diffusing reflection in ox leather surface, with photoextinction, while by
In the elongated tubular characteristic of carbon nanotube, so that the texture of ox leather surface is more naturally beautiful.
In addition, the both ends of carbon nanotube also have suction-operated, ox-hide leather usually requires periodically to be nursed with care agent to protect
Its brightness and feel are demonstrate,proved, and carbon nanotube can then adsorb a certain amount of care agent, and during the loss of care agent not
Disconnected slow release so that care agent is constantly supplemented, with extend ox leather surface oil film there are the times, to extend
The service life of ox-hide leather.
Further, according to parts by weight, the hand feeling agent includes following components:
Further, according to parts by weight, the hand feeling agent includes 25-26 parts of microwax.
By using above-mentioned technical proposal, although paraffin and microwax are extract from petroleum, paraffin
Be it is brittle, fracture is easy to after stress and is even crushed, and the hardness of microwax is small, and flexibility is fine, and stress is easily deformed, no
Easy fragmentation.And microwax can be used as the modifying agent of paraffin, to paraffin in add microwax after, the plasticity of paraffin can be improved,
So that there is physically better performance after hand feeling agent film forming.
Further, according to parts by weight, the emulsifier uses paregal O.
By using above-mentioned technical proposal, paregal O is that one kind is non-ionic by surfactant, and main component is polyoxy
Ethylene fatty alcohol ether has good emulsification, so that hand feeling agent forms a uniform system.
Further, according to parts by weight, the hand feeling agent includes 24-25 parts of caryophyllus oil.
By using above-mentioned technical proposal, the main component of caryophyllus oil is eugenol, carypohyllene, Acetyl eugenol, first
Base amyl ketone etc. has osmosis in the application of hand feeling agent, so that leather still has well after surface layer is worn
Feel, adsorbed care agent can be discharged into the leather surface after abrasion in this outside carbon nanotube, and carry out timely
Nursing.
Further, the emulsifier includes emulsifier TX-4, and the mass ratio of the emulsifier TX-4 and paregal O is 1:
1。
By using above-mentioned technical proposal, single emulsifier is bad to organosilicon emulsifying effectiveness, is easy to appear oil slick
Situation, and after emulsifier TX-4 and paregal O are mutually compound, good emulsion stability obtained by emulsification
Further, hand feeling agent preparation method the following steps are included:
Step 1, by paraffin and microwax heating melting；
Step 2, fatty acid is added, mixes and melts with wax, until transparence；
Step 3, emulsifier TX-4 is added, paregal O and silicone emulsion are emulsified, 70-80 DEG C of emulsifying temperature, when emulsification
Between be 25-35min, mixing speed 500-600r/min；
Step 4, caryophyllus oil and carbon nanotube are added under stiring, continues to stir 5-10min, warm water dilutes and continues to stir
It mixes 20-30min and takes out finished product.
In conclusion the invention has the following advantages:
1. adding carbon nanotube in hand feeling agent, after carbon nanotube is uniformly distributed, formed in ox leather surface slight convex
It rises, so that light generates certain diffusing reflection in ox leather surface, there is photoextinction, simultaneously because the elongated tubular of carbon nanotube
Characteristic, so that the texture of ox leather surface is more naturally beautiful；
2. the both ends of carbon nanotube also have suction-operated, ox-hide leather usually requires periodically to be nursed with care agent to guarantee it
Brightness and feel, and carbon nanotube can then adsorb a certain amount of care agent, and constantly slow during the loss of care agent
On The Drug Release so that care agent is constantly supplemented, with extend ox leather surface oil film there are the times, to extend ox-hide
The service life of leather；
Although 3. paraffin and microwax are extract from petroleum, paraffin be it is brittle, hold very much after stress
Easy fracture even crushes, and the hardness of microwax is small, and flexibility is fine, and stress is easily deformed, not easily broken.And microwax can be with
As the modifying agent of paraffin, to paraffin in add microwax after, the plasticity of paraffin can be improved so that hand feeling agent film forming after
With physically better performance；
4. the main component of caryophyllus oil is eugenol, carypohyllene, Acetyl eugenol, methyl amyl ketone etc., in hand feeling agent
Application in there is osmosis so that leather still has good feel after surface layer is worn, this outside carbon received
Adsorbed care agent can be discharged into the leather surface after abrasion in mitron, and be nursed in time.
