Description
Technical field
The present invention relates to artificial leather dyeing and printing process fields, and in particular to a kind of work using Dragonfruit Juice printing and dyeing artificial leather
Skill.
Background technology
Printing and dyeing are also referred to as dyeing and finishing.Dye molecule is formed after being handled by physical and chemical process with cloth or artificial leather green body
Steadily combine.In dyeing process, common chemical synthetic dye can generate substantial amounts of pollution, and the cloth after dye transfer or people
On fabricate-leather, can also there be the substance of more multipair human health, be unfavorable for the health of human body.For this purpose, people are in dyeing process
In, it was found that natural dye, predominantly vegetable colour print and dye to cloth, artificial leather etc., can either so reach preferable
Printing and dyeing effect, also can avoid harmful substance from remaining in artificial leather, cloth, be conducive to the health of human body, while can also drop
The generation of pollutant in low dyeing process.But, it has to it says, vegetable colour, the adhesion on artificial leather is poor,
After printing and dyeing during use, the situation faded, faded easily is generated.
Dragon fruit is the fruit of cactaceous perennial succulent, and nutritive value is high, there is anti-oxidant, anti-freedom
The effect of base, anti-aging.In recent years, it is more and more to be related to the technique of extracting of dragon fruit pigment, thus also illustrates flue
Fruit not only has good effect on edible, and pigment also has good use value on other field.The skin of dragon fruit is in
Dark red to rose, primary pigments ingredient is Betacyanins, bright-colored, and extraction is easy, generally using solvent, microwave, is surpassed
The extracting methods such as sound wave.But the application after being extracted on its pigment, is also rarely reported.
The content of the invention
It is an object of the invention to provide a kind of adhesive force that can promote vegetable colour on artificial leather, so that after printing and dyeing
Artificial leather not fugitive color, fade using Dragonfruit Juice printing and dyeing artificial leather technique.
To solve the above problems, the technical solution adopted in the present invention is as follows：
A kind of technique using Dragonfruit Juice printing and dyeing artificial leather includes the following steps：

Heat steams 60min；
F. final finishing：It will be cleaned 2 times by the clear water used for artificial leather of step e processing, shady place air-dries.
Compared with prior art, the invention has the advantages that：
1st, in dyeing and printing process of the invention, it is used as mordant by adding in color fixing agent and containing the tannin extract of tannin, it can
So that the ligands such as hydroxyl, carboxyl contained on phytochrome molecule and with hydroxyl contained on fiber molecule on artificial leather
Form complicated multicomponent complex so that the active force increase between the fiber molecule on phytochrome and artificial leather is promoted and planted
Adhesive force of the object dyestuff on artificial leather；
2nd, by neutralisation treatment, the free acid on artificial leather is neutralized, enhances fiber molecule on artificial leather and dyestuff
Infiltration and combination so that dyeing is more uniformly distributed；In addition, in N-process, pH value is slowly promoted, can further open fiber
Passage between molecule so that the depths that phytochrome molecule can further penetrate into artificial leather leather is formed with fiber molecule
Multicomponent complex further promotes adhesive force of the vegetable colour on artificial leather；
3rd, after dyeing, hot steaming processing is carried out, can speed up the movement of artificial leather plants on surface pigment molecular, and by glue
Gap is further opened between fibrinogen so that phytochrome molecule enters the higher depth of artificial leather so that the plant on artificial leather surface
Object pigment molecular is less, and the fixation ability of artificial leather is stronger.
The present invention is described in detail With reference to embodiment.
