Description
Technical field
The present invention relates to tanning technology field, and in particular to pretreating agent and preprocess method are used before a kind of leather coloring.
Background technology
Non-aqueous dyeing, is worldwide considered to be the revolution to traditional Dyeing-finishing Industry.Since 20 end of the centurys, some states
Family begins one's study non-aqueous dyeing new technology.The middle sample machine that 30L has been developed in Germany foremost is walked at present.Recently, east China
Country of university dyeing and finishing Engineering Technical Research Centre also have developed 1.6L, lab scale model machine, according to the latest news, 30L middle sample machine
It will come into operation.The key of the technology be whole dyeing course it is anhydrous, without auxiliary agent, pollution-free, not only saved but also efficiently, it is fine to terylene
Substantially, its essence is still Dyeing In The Medium Of Supercritical Carbon Dioxide to the colouring effect of some high-performance specialty fibers of peacekeeping, this skill
Art is expected the cap for making the traditional dyeing and finishing industry of continuity centuries take " pollution ".This waterless staining technique is such as promoted in the whole nation,
Can economize on water 20 billion cubic meters every year.
As what people recognized and studied to supercritical fluid, sonochemistry, electrochemistry further gos deep into, and dyestuff system
The raising of standby technology, efficient, cleaning leather coloring will be obtained to be developed faster.From now on, the developing direction of leather coloring be by
Colouring method and high-performance dyestuff combine, actively develop Biomimetic Dyeing, reactive dye (environment-friendly type) dyeing, electrostatic or
The ecological dyeing technology such as magnetic color.But at present, there is not been reported for the non-aqueous dyeing of contrast leather.
The content of the invention
The technical problems to be solved by the invention are to improve before a kind of clean environment firendly, the stable leather coloring of performance with pre-
Inorganic agent.
The technical problems to be solved by the invention are realized using following technical scheme：
Pretreating agent is used before a kind of leather coloring, is made up of the component of following parts by weight：Stabilizer 80-12g, urea
65-75g, activator 25-35g, bleeding agent 4-6g, prevent reducing agent 8-120g, ethylenediamine tetra-acetic acid 1.5-2.5g, polyethylene glycol
25-35g, curcumin 4-6g, calcium activated 8-12g, water 650-900g.
The preferable weight of above-mentioned each component is：Stabilizer 100g, urea 70g, activator 30g, bleeding agent 5g, prevent reduction
Agent 10g, ethylenediamine tetra-acetic acid 2g, polyethylene glycol 30g, curcumin 5g, calcium activated 10g, water 780g.
The activator is sodium carbonate.
The stabilizer is mosanom.
The application selects calcium activated, and it contains the elements such as micro natural mineral matter potassium, sodium, iron, manganese, silicon, phosphorus, zinc, this
A little elements largely have physiological function, be the key component of enzyme and protein system, nucleic acid hormone, cell membrane etc. are played surely
Fixed or activation, can promote to remove from office absorption of the base to various materials, improve treatment effect.
The processing method of above-mentioned pretreating agent is as follows：
(1) inject water into reactor, open steam valve, reactor is heated up, controlling reaction temperature 60~
105 DEG C, kept for 15 minutes, add calcium activated, stabilizer and activator from head tank, be then turned on reactor and be stirred, stirred
Speed control mixes 35 minutes at 260~280 revs/min, each material is fully dissolved mixing；
(2) after stirring terminates, material in reactor is down to normal temperature, urea, bleeding agent is put into, prevents reducing agent, second two
Amine tetraacethyl, curcumin and polyethylene glycol, first stir 10-15 minute, then rise kettle temperature, control temperature at 70 DEG C, 260~
Continuously stirred under 280 revs/min 20 minutes；
(3) mixed liquor in step (2) is filtered, obtains filtered fluid, as pretreating agent.
To obtain good Color, it is necessary to leather base is pre-processed before dyeing, brushing pretreating agent is different
Pretreating agent produces different influences to the definition of dyeing pattern, and by the regulation to inorganic agent viscosity, enables coating very
It is uniformly coated.
Above-mentioned mosanom is the solution of sodium alginate that concentration is 5%.
Preprocess method is used before a kind of leather coloring, is comprised the following steps that：
(1) the leather base after degreasing is first placed 4-8 hours in humidity 85-90%, the storehouse of 6-10 DEG C of temperature, will during placement
Leather base take on the top of the shelf or directly on the ground, should not be stacked；By high humidity low-temp storage, reduce inside leather base
Moisture evaporation；
(2) the leather base in storehouse is taken out, feeding tumbler carries out tumbling processing, and one was vacuumized every 5-8 minutes during tumbling
It is secondary, exhaust every time after vacuum tumbling 5-10 minutes, then vacuum pumping, is so circulated 2-4 times so that leather base energy in tumbling procedure
The effect of breathing massage is enough reached, reduction inner material is hardened, makes cortex more soft, is easy to colouring；
(3) the leather base after tumbling is put into the PEG-400 polyglycol solutions that concentration is 30%, 60 points of normal temperature dipping
Clock, then takes out extension on the top of the shelf, to no liquid drippage；Then leather base is paved, fully sprays pretreating agent with spray gun, put
Put more than 80 minutes, then spray another side；
(4) leather base is put into progress dyeing processing in staining reaction kettle, dyeing temperature in the kettle is in 75-90 DEG C, dyeing caldron
Pressure is 15-22MPa, and dyeing time is 20-60 minutes；
Above-mentioned staining reaction kettle uses supercritical CO 2 dyeing kettle, and wherein supercritical carbon dioxide fluid flow velocity is 10
~20g/min.
(5) leather base is taken out after the completion of dyeing and is put into another reactor, steam is then injected into reactor, anti-
Answer the steam temperature in kettle to stop injection steam when reaching 90-110 DEG C, while starting agitating function, be heated evenly material, stir
Mix 20-35 minutes, then water filling is cleaned；The color fastness of leather can be improved using steam heating；
(6) the leather base after cleaning is placed in vacuum and low temperature cold wind drier, be dried under 50-55 DEG C of environment of temperature
Processing, obtains finished product.
Processing is dried from vacuum and low temperature cold air drying technology, so that product keeps preferable pliability, protective coloration
Pool is injury-free, and drying temperature and time are the optimal parameter obtained in substantial amounts of experimental basis, the production obtained under the conditions of this
Quality is preferable, and easily industrialized production.
The beneficial effects of the invention are as follows：Present component is simple, and use cost is relatively low, and leather is located in advance before dyeing
Reason, can be greatly enhanced the production efficiency of leather coloring, reduce pollution of the leather coloring process to environment, reduce the life of process hides
Cost is produced, the performance of colouring leather is improved.
