Product class and added value, that widens a rabbit utilizes scope, it is possible to significantly improve raising rabbit
Economic benefit with processing man rabbit.Family's popular pattern of rabbit mainly have on monochrome, grass white,
One mao of double-colored, one mao of trichroism, stamp etc..
Wherein " one mao double-colored " refers to that the lower floor of fur and upper strata are two kinds of colors, " frost on grass "
Effect substantially fur upper strata is " one mao double-colored " effect of white.Nature wild
The animal fur overwhelming majority is one mao of polychrome or gradient color, and some hairs have 5 from root to tippy tea
Plant the color joint of above color." the one mao double-colored " effect made with family's rabbit, has under hair shallow
Color, hair pin are dark and under hair dark, style in hair pin light color 2, according under hair normal complexion hair pin
Color colour match requires difference, needs to use different processes.
For under hair light color, " one mao double-colored " effect of hair pin dark color: first use acid stain
Dye background color, after drying, then sprays acidity tippy tea dyestuff or brushes in tippy tea layer, vapour steaming colour fixing,
Washing loose colour, is dried and arranges, and this method is applicable to tippy tea dyestuff used by under hair normal complexion to be had
Color compatibility after, it is possible to produce the situation of tippy tea color of sample requirement.
, " one mao double-colored " effect of hair pin light color dark under hair:
Method 1-pulling color method
Employing can not by the dyestuff of pulling color and can by the grass of pulling color frost dyestuff compatibility by hair
Skin dyes the color needed under hair, carries out tippy tea pulling color, at this moment tippy tea with pulling color agent after drying
On can be taken out by the dye colour of pulling color, remaining can not be by the color of the dyestuff of pulling color.
Method 2-dawn tippy tea secondary staining
First dye the color of under hair requirement with grass upper frost dyestuff, then by tippy tea dawn, then will
Tippy tea dyestuff brush or be sprayed in the tippy tea section of dawn, decatize colours.This method is applicable under hair
Color can not comprise the situation of tippy tea color, such as, require that under hair is large red, and tippy tea is emerald green,
Under hair is dark blue, and tippy tea is gorgeous Huang etc..
The fashion of fur product is increasingly stronger at present, and its popular pattern gets more and more.Along with hair

Wherein said solid fluorescence dyestuff is the sulfonic group sodium salt of anthraquinone type, and it is mainly composed of
Sulfonic group sodium salt, content is the 10%～30% of described solid fluorescence dyestuff total amount.
Compare in traditional method, " a mao double-colored " that under hair to be reached is dark, pin hair is light
Effect, or by can not by the dyestuff of pulling color and can by the grass of pulling color frost dyestuff compatibility contaminate
After color, using physics pulling color agent to be pulled out by frost dyestuff on the grass on tippy tea, remaining can not
Color by the dyestuff of pulling color；Or directly with grass upper frost dyeing, the most again by tippy tea
Dawn, spray on tippy tea or brush afterwards on tippy tea dyestuff.And under hair light color, pin hair deep
" one mao double-colored " effect of color, directly with acid dyeing, then by acidity tippy tea dyestuff
Spraying or brush in tippy tea layer, fixation obtains.Primary colours after the dyeing of above-mentioned traditional method only one,

Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail, below
Embodiment of the present invention will be described in detail in conjunction with the embodiments, but art technology
Personnel are it will be appreciated that the following example is merely to illustrate the present invention, and are not construed as limiting this
The scope of invention.
Family's rabbit one mao of double-colored method of dye, specifically includes following steps:
(1) family's Corii seu pilus Leporis of no dyeing is carried out pretreatment；Pretreatment specifically includes: first
The family's Corii seu pilus Leporis chosen is carried out pre-tanning process, carries out retanning process the most again.
Wherein, the selection of raw material skin is also important before PROCESS FOR TREATMENT one, and this is to do skin
Basis, raw material cortex amount is good, and post-treatment gets up the most.Want when raw material skin selects
Reject run-bake-needle fault to fall hair, have yellowish urine, have knot hair, dried-up hair, Testudinis hair, broken plate, rotten plate etc. to lack
The fur fallen into, selects to meet that technique and user require, not through hyperchromatic rabbit hide
Dye.
The physical and chemical process making rawhide become leather by tanning is crucial, if rawhide not tanning,
Dermatotome can not have any intensity, and resistance to physics, chemical property are poor, it is impossible to be long placed in, and lose it
Value, rawhide does not becomes the leather without value by tanning, the basic nothing of follow-up work
Method is carried out.So, premise must tanning.
Pre-tanning processes and specifically includes: prepare tanning agent at 30-40 DEG C, after 6-7 hour, uses
Family's Corii seu pilus Leporis, to 4.5-5, is put into by the pH value of the sodium bicarbonate described pre-tanning agent of regulation afterwards,
Soak 10-12 hour.Preferably, preparation temperature can be any between 30 DEG C to 40 DEG C
Point value.Preferably regulation pH value is 4.6-4.8, and soak time is preferably 11 hours.In advance
In tanning agent, main component includes: salt, wetting agent, without aldehyde tanning agent, auxiliary tanning agent, wherein with
Weight meter, containing 30-40 gram of salt in every 1000 grams of described pre-tanning agents, 2-3 milligram moistening
Agent, 4-5 gram without aldehyde tanning agent, 2-3 gram of auxiliary tanning agent, remaining as water.Preferably, pre-tanning agent
Formula be 33-37 gram of salt, 2.3-2.6 milligram wetting agent, 4.2-4.8 gram without aldehyde tanning agent, 2.4-2.9
Gram auxiliary tanning agent, remaining as water.
Wherein, can be aluminium tanningagent or chrome tanning agent without aldehyde tanning agent, pre-tanning is mainly aluminum tanning
Agent (includes Alumen and aluminum sulfate), all exists with complex form in aqueous solution.Aluminum complexation
The central ion of thing is trivalent aluminium ion, be also 6 ligands around aluminium ion with aluminum from
Son coordination, in regular octahedron structure.Aluminium complex and the ionization carboxyl coordination on collagen peptide bond
In conjunction with, and produce crosslinked action at peptide bond, but due to ligand and aluminum ions coordination power
Little, thus the most water-fastness, i.e. can produce tempering after washing, owing to aluminium complex molecule is little,
Crosslinking ability is little, so aluminum tanning skin stability is the highest, shrinkage temperature is low.So will carry out after
Continuous chrome retanned.
Auxiliary tanning agent is preferably carboxylic acid sodium salt, mainly has the alkaline matter improving pH value,
Aluminium tanningagent is in pre-tanning early stage pH probably 2.8～about 3.0, and the pre-tanning later stage needs with helping
Tanning agent brings up to pH5.0～5.2.In the case of this pH, aluminium tanningagent and collagen peptide bond resultant are
Greatly, the most firmly, the optimum efficiency of aluminum tanning is reached.
The pre-tanning of upper step makes dermatotome shrinkage temperature reach 65～70 DEG C, does not still reach dyeing and is wanted
The temperature asked, is also chrome tanning followed by retanning, make dermatotome shrinkage temperature reach 90 DEG C with
On, lay the groundwork for the dyeing of lower step.
Retanning is processed as: prepare retanning agent at 32-35 DEG C, adjusts with sodium bicarbonate after 6-7 hour
Joint pH value is 4.4-4.6, is warming up to 38-39 DEG C, puts into the family's Corii seu pilus Leporis through tanning and soaks
Go out skin after 10-12 hour to be dried.In described retanning agent, main component includes: salt, wetting agent,
Chromium powder, auxiliary tanning agent；The most by weight, containing salt in every 1000 grams of described retanning agents
30-40g, wetting agent 0.5-1 milligram, chromium powder 5-7 gram, auxiliary tanning agent 2-3 gram, residual components
For water.
Chrome tanning agent: i.e. chromium powder, the most chromic basic salt (each complex) and collagen
Peptide bond generates crosslinking suturing, i.e. forms two point and the reaction of multiple spot combination, and chrome tanning makes
Hide physical and chemical performance is greatly improved, and shrinkage temperature reaches more than 90 DEG C.
In pre-tanning processes with retanning, remaining composition of use, such as salt: be conventional
Soaking, immersion salt mainly has Sal, Natrii Sulfas etc..The effect of salt is to dissolve between fiber
Matter, destroys the secondary key between collagen peptide bond, suppresses bacterial reproduction, minimizing to fall hair and acid is swollen.
Wetting agent: the clear water rawhide moistening osmosis to there being oils and fats is the least, therefore hide backwater speed
Degree is slow.Wetting agent has the multiple works such as moistening, infiltration, defat, decontamination dissolving interfibrillar substance
With, because accelerating immersion speed, defat, clean effect is notable, and easy to use, right
Hair has no side effect substantially, is main hide backwater auxiliary agent.
(2) dyeing: pretreated Corii seu pilus Leporis is first used solid fluorescence dyestuff as tippy tea
Dyeing, adds grass upper frost dyeing with bath afterwards；
Dyeing is a complicated physics and chemical process, comprises: 1. the dyestuff in dye liquor divides
Son is close to fiber surface, diffusion；2.: dyestuff is adsorbed by fur from solution；3.: dye
Expect to spread to wool fibre internal penetration；4.: dyestuff is combined with wool fibre.This four step is in dyeing
In influence each other, occur together, promote each other, and in a kind of dynamic equilibrium.Pass through technique
Condition, finally make the dyestuff in solution substantially be absorbed by fiber and combine.Tippy tea dyestuff because of
Its structure influence, needs higher dyeing temperature (65 DEG C～75 DEG C), in order to same after making dyeing
Wool fibres different on hide has identical color, needs higher dyeing temperature and longer
Dyeing time.During dyeing, it is 20:1 with the mass ratio of water Yu hide, on this basis
Dye.
Wherein, tippy tea dyestuff is the solid fluorescence dyestuff of the resistance to reducing agent of a kind of comparison, uses institute
The time stating tippy tea dyeing is 1.5-1.6 hour, when adding grass upper frost dyestuff continuation dyeing
Between be 1.5-1.6 hour；Temperature in described dyeing course is 70-75 DEG C.Normal dyeing
Temperature is 65 DEG C, and dyeing time is 2 hours.
(3) with the pulling color liquid being mainly composed of chemistry pulling color agent, the family's Corii seu pilus Leporis after dyeing is entered
Row epilation point processes.
The pulling color agent used in the present invention is that one has reproducibility fragrance Organic substance and stabilizer
Mixture, its effective ingredient is sodium hydrosulfite.Dawn principle is to break with reducing agent or oxidant
Structure in bad dye molecule, is made dyestuff colour killing, and is gone by washing or additive method
Remove.The method that the method uses is reduction dawn.
Described pulling color liquid is equipped with formic acid by chemistry pulling color agent and water is made；Wherein said chemistry
The proportioning of pulling color agent, formic acid and water is 2:1:40-2:1:60, most preferably, formic acid
It is 2:1:50 with the proportioning of water.If discharge reduction, pulling color agent and amount of formic acid liter must be made
Height, the pulling color agent of excessive concentrations and formic acid can damage fur, and hypervolia then can dilute pulling color
Agent, affects pulling color effect, therefore water yield general control is advisable between 40～60；Pulling color agent
I haven't seen you for ages causes pulling color not thorough, too much can damage fur；Formic acid is assosting effect, in acidity
Under the conditions of, the reduction pulling color effect of pulling color agent could preferably embody effect, by experiment
Drawing pulling color agent: formic acid=2:1 is optimal proportion, formic acid is too little or too much all can be affected also
Former pulling color.
And formic acid for dyestuff pH when about 3.0 the strongest with fur binding ability, before dyeing
Phase, body lotion pH was higher, and the later stage adjusts pH about 3.0 with formic acid, plays tint retention.Dye
The color later stage adds formic acid fixation, pH value 3.0 when going out skin.
During preparation pulling color liquid, first with water, pulling color agent is fully melted, add formic acid, stirring
Uniformly, stand-by.
Pulling color method: with injection uniformly as standard, spray gun is to be preferably selected, and pulling color liquor ratio is relatively
Watering can be selected time few；Pulling color liquid is uniformly sprayed above fur, treats that fur is the wettest
Moisten, proceed to go out skin after steam box steams Preset Time and be dried.
In the present invention, epilation point processes and specifically includes: be first uniformly sprayed on the pulling color agent of described chemistry
On fur after dyeing, put into steam box afterwards, steam 15-20 minute at 70-75 DEG C.Because
Chemical reaction needs suitable environment just can carry out, and reduction pulling color is no exception, through a large amount of
Experiment proves that 70 DEG C～75 DEG C steamings 15 minutes are optimum response environment, the too low sluggish of temperature,
Time-consuming, temperature is too high can damage fur, causes the failure of an experiment；Time is less than 15 minutes then also
Former dawn is not thorough, affects double-colored making effect, and the time oversize fur that can damage is time-consuming.

7) wood bran is turned: be specially addition 250mL brightener in every 40 kilograms of wooden brans and make light
Bright dose, the family's Corii seu pilus Leporis mixture made and tanning being disposed puts in processing equipment
Turn and go out skin in 4 hours.
8) warehouse-in is arranged.
Compare in traditional method, " a mao double-colored " that under hair to be reached is dark, hair pin is light
Effect, or will not be able to by the dyestuff of pulling color and can by the grass of pulling color frost dyestuff compatibility
After dyeing, use physics pulling color agent to be pulled out by frost dyestuff on the grass on tippy tea, remain not
Can be by the color of the dyestuff of pulling color；Or directly with grass upper frost dyeing, the most again by hair
Point dawn, spray on tippy tea or brush afterwards on tippy tea dyestuff.And under hair light color, hair pin
Dark " one mao double-colored " effect, directly with acid dyeing, then by acidity tipping
Material sprays or brushes and tippy tea layer, and fixation obtains.Primary colours after the dyeing of above-mentioned traditional method only have one
Kind, and the pulling color agent used is physics pulling color agent, its pulling color less effective, after pulling color
Often having the acid stain of remnants above fur, the effect of " a mao double-colored " is bad.
Relative to above-mentioned prior art, the present invention uses and first uses tippy tea dyestuff to dye,
Add grass upper frost dyeing with bath the most again, finally re-use pulling color liquid to the family after dyeing
Corii seu pilus Leporis carries out point process of pulling off the feather of, and so the background color of the family's Corii seu pilus Leporis after dyeing is tippy tea dyestuff
With the blend color of frost dyestuff on grass so that the color of the family's Corii seu pilus Leporis after dyeing is more gorgeous.
And re-use the chemistry pulling color agent point that carries out pulling off the feather of afterwards and process, pulling color effect is more thorough so that
Difference between tippy tea and background color is obvious, and the effect of " a mao double-colored " is more preferable.This technique can make
Rabbit leatherware has gorgeous color, and fur more has third dimension, it is possible to increase adding of family's rabbit
Value.And because pulling color processes ratio more thoroughly, it is also possible to the tippy tea position system after pulling color
Make two-color effect.
Although illustrate and describing the present invention with specific embodiment, but it will be appreciated that
May be made that without departing from the spirit and scope of the present invention many other change and
Amendment.It is, therefore, intended that include in the following claims belonging in the scope of the invention
All such changes and modifications.
