Description

A kind of technique utilizing mustard printing and dyeing artificial leather
Technical field
The present invention relates to artificial leather dyeing and printing process field, be specifically related to a kind of technique utilizing mustard printing and dyeing artificial leather.
Background technology
The deterioration of environmental quality and the imbalance of the ecological balance, allow facing mankind serious environmental crisis.Industrial production is a large source of environmental pollution, and wherein, dyeing industry stands in the breach.Waste water from dyestuff colourity is dark, organic pollution content is high, the large difficult for biological degradation of complicated component, heavy metal and bio-toxicity, the anti-light solution of dyestuff, non-oxidizability are strong, and containing the multiple organic matter having bio-toxicity or cause " three cause " performance, the harm of environmental pollution is very large.
In order to protection of the environment, the living environment that also mankind one are suitable.Environment-friendly dye has become the emphasis of dyeing development.Natural plant dye is the one of environment-friendly dye, and it obtains from plant, Animal resources, seldom or not through chemical process.
Natural dye is nontoxic, to skin without anaphylaxis and carcinogenic.There is good biodegradability and Environmental compatibility.Its color and luster is soft, naturally characteristic, in the fields such as high grade true silk goods, health-care underclothes, home textile product, adornment, have vast potential for future development.Exploitation natural dye is not only conducive to protecting national resource and ecological environment, and has more vast potential for future development to the textiles of some high added values of exploitation.But because the research of the extractive technique of natural dye, the aspect such as level-dyeing property and light fastness is also less, and the technique nowadays utilizing natural dye to carry out printing and dyeing is more complicated, operates more, and natural dye is not well promoted.
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 mustard 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:

Get 8 pieces of PVC artificial leather, the dyeing and printing process respectively through embodiment 1-5, comparative example 1-3 carries out printing and dyeing process, then cuts the skin bit of 1 piece of 5cm × 5cm size from the PVC artificial leather after every block printing and dyeing, carry out stripping extraction experiments, extract selects the pyridine solution of 25%, above-mentioned skin bit is placed in respectively the flask of 50mL, adds 10mL extract, then 60 DEG C are heated to, constant temperature 25min, pulls out, cleaning, dry, observe situation of stripping; Concrete outcome refers to following table 1:
Table 1: to strip information slip through the extraction of stripping of the PVC artificial leather of embodiment 1-5, comparative example 1-3 process
Adopt above-mentioned PVC artificial leather, after drying, repeat aforesaid operations, observe and the required number of times through extraction experiments of stripping that recorder's fabricate-leather is stripped completely, concrete data refer to following table 2:
Table 2: to strip completely data logger through the artificial leather of embodiment 1-5, comparative example 1-3 process
Experimental group Embodiment 1 Embodiment 2 Embodiment 3 Embodiment 4
Number of processes 9 times 7 times 7 times 6 times
Experimental group Embodiment 5 Comparative example 1 Comparative example 2 Comparative example 3
Number of processes 5 times 2 times 4 times 3 times
As can be seen from the data in upper table 1-2, dyeing and printing process of the present invention, significantly can promote the adhesive ability of vegetable colour on artificial leather, makes the artificial leather after printing and dyeing process be not easy to produce the situation of fading, fading.
Above-mentioned embodiment is only the preferred embodiment of the present invention; can not limit the scope of protection of the invention with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present invention all belong to the present invention's scope required for protection.
