Description
Technical field
The present invention relates to artificial leather dyeing and printing process field, be specifically related to a kind of technique utilizing Dragonfruit Juice printing and dyeing artificial leather.
Background technology
Printing and dyeing are referred to as dyeing and finishing again.Dye molecule is stably combined by being formed with cloth or artificial leather base substrate after physical and chemical process process.In dyeing process, common chemical synthetic dye can produce a large amount of pollutions, and on cloth after dye transfer or artificial leather, also can there is the material of more multipair human health, be unfavorable for the health of human body.For this reason, people are in dyeing process, find natural dye, be mainly vegetable colour to print and dye to cloth, artificial leather etc., effect of printing and dyeing preferably can either be reached like this, also harmful substance can be avoided to remain in artificial leather, cloth, be conducive to the health of human body, also can reduce the generation of pollutant in dyeing process simultaneously.But have to, vegetable colour, the tack on artificial leather is poor, in the process that printing and dyeing use afterwards, easily produces the situation of fading, fading.
Dragon fruit is the fruit of cactaceous perennial succulent, and it is of high nutritive value, and has anti-oxidant, Green Tea Extract, antidotal effect.In recent years, have the technique of extracting about dragon fruit pigment to get more and more, also illustrate that dragon fruit not only has good effect on edible thus, its pigment also has good use value on other field.The skin of dragon fruit is dark red to rose, and primary pigments composition is Betacyanins, and it is bright-colored, extracts easily, generally uses the extracting methods such as solvent, microwave, ultrasonic wave.But the application after extracting about its pigment, also rarely has report.
Summary of the invention
The object of the present invention is to provide and a kind ofly can promote the adhesive force of vegetable colour on artificial leather, fugitive color, the Dragonfruit Juice that utilizes that fades are not printed and dyed the technique of artificial leather to make the artificial leather after printing and dyeing.
For solving the problem, the technical solution adopted in the present invention is as follows:
Utilize a technique for Dragonfruit Juice printing and dyeing artificial leather, comprise the steps:
A. pitaya peel preparation of dyestuff: get dragon fruit pericarp, ultramicro grinding, obtain pulp and then add the alcohol that concentration is 80%, the volume of described alcohol and the mass ratio of pitaya peel are 5-10:1, dipping 12-24h, with 80-100 object screen filtration, collect filtrate; Then filter residue is adopted identical soaking in alcohol, 12-24h, with 80-100 object screen filtration, collect filtrate; Merge the filtrate of collecting for twice, concentrated, vacuumize, obtains solid, i.e. dragon fruit dyestuff;
B. dyestuff preparation: get the following component according to parts by weight: the dragon fruit dyestuff 28-32 part obtained through a step, tannin extract 4-6 part, color-fixing agent 1.5-2.5 part, surfactant 0.8-1.2 part, sodium chloride 0.2-0.5 part and water 40-60 part; By upper each component mixing, homogeneous stirs, and obtains dyestuff;
C. artificial leather process: the artificial leather after tanning process of learning from else's experience carries out acidleach, neutralisation treatment, the acid solution pH value that acidleach adopts is 1.5-2.5; Neutralisation treatment is specially: in the acid solution of dipping, add alkali carry out neutralisation treatment 30-45min, and every 5min improves pH value 0.4-0.6;
D. dye: the artificial leather after step c process is immersed within 30s in the dyestuff that b step is obtained, at the temperature of 30-40 DEG C, dipping 25-35min;
E. heat is steamed: by the artificial leather after Step d process temperature be 80-120 DEG C, pressure is 0.5-1.5kg/cm
2steam under heat steam 30-90min;
F. Final finishing: by the clean water used for artificial leather through step e process, shady and cool place is air-dry.
In the present invention, preferred scheme is the tannin extract in described b step is chestnut extract.
In the present invention, the preferred scheme at least one that to be the color-fixing agent in b step be in cetylpyridinium chloride, brocide and crosslinked color-fixing agent DE.
In the present invention, the preferred scheme at least one that to be the surfactant in described b step be in lecithin, neopelex, dioctyl succinate disulfonate acid, Tween-80.
In the present invention, preferred scheme is also comprise d1 step between described Step d and step e: stamp: adopt printing machine to carry out stamp process to the artificial leather through Step d process, and the environment temperature of stamp process is 25-35 DEG C, humidity is 35-50%.
In the present invention, preferred scheme is that the alkali that described step c adopts is selected from alkali-metal carbonate, alkali-metal phosphate, NaOH and potassium hydroxide.
In the present invention, preferred scheme is that the clean water in described f step is specially: with the artificial leather 30s of clean water through step e process, clean 2-3 time.
In the present invention, preferred scheme is, the described technique utilizing Dragonfruit Juice printing and dyeing artificial leather, comprises the steps:
A. dragon fruit preparation of dyestuff: get dragon fruit pericarp, ultramicro grinding, obtain pulp and then add the alcohol that concentration is 80%, the volume of described alcohol and the mass ratio of dragon fruit are 6:1, dipping 13h, with 100 object screen filtrations, collect filtrate; Then filter residue is adopted identical soaking in alcohol, 13h, with 100 object screen filtrations, collect filtrate; Merge the filtrate of collecting for twice, concentrated, vacuumize, obtains solid, i.e. dragon fruit dyestuff;
B. dyestuff preparation: get the following component according to parts by weight: the dragon fruit dyestuff 30 parts, tannin extract 4 parts, 2 parts, color-fixing agent, 1 part, surfactant, 0.3 part, sodium chloride and 55 parts, the water that obtain through a step;
By upper each component mixing, homogeneous stirs, and obtains dyestuff;
C. artificial leather process: the artificial leather after tanning process of learning from else's experience carries out acidleach, neutralisation treatment, the acid solution pH value that acidleach adopts is 2.3; Neutralisation treatment is specially: in the acid solution of dipping, add sodium bicarbonate carry out neutralisation treatment 40min, and every 5min improves pH value 0.4;
D. dye: the artificial leather after step c process is immersed within 30s in the dyestuff that b step is obtained, at the temperature of 35 DEG C, dipping 30min;
E. heat is steamed: by the artificial leather after Step d process temperature be 95 DEG C, pressure is 0.8kg/cm
2steam under heat steam 60min;
F. Final finishing: by the clean water used for artificial leather 2 times through step e process, shady and cool place is air-dry.
Compared with prior art, tool of the present invention has the following advantages:
1, in dyeing and printing process of the present invention, by add color-fixing agent and containing the tannin extract of tannin as mordant, the contained ligand such as hydroxyl, carboxyl can be made on phytochrome molecule and forms complicated multicomponent complex with contained hydroxyl on fiber molecule on artificial leather, active force between fiber molecule on phytochrome and artificial leather is increased, promotes the adhesive force of vegetable colour on artificial leather;
2, by neutralisation treatment, neutralize the free acid on artificial leather, strengthen infiltration and the combination of the fiber molecule on artificial leather and dyestuff, make to dye more even; In addition, in N-process, promote pH value slowly, the passage between fiber molecule can be opened further, the depths and the fiber molecule that make phytochrome molecule further can penetrate into artificial leather leather form multicomponent complex, the adhesive force of further lifting vegetable colour on artificial leather;
3, after dyeing, carry out heat and steam process, the motion of artificial leather plants on surface pigment molecular can be accelerated, and gap between collagenous fibres is opened further, phytochrome molecule is made to enter the comparatively depths of artificial leather, make the phytochrome molecule on artificial leather surface less, the fixation ability of artificial leather is stronger.
Below in conjunction with detailed description of the invention, the present invention is described in detail.
