Abstract
The invention discloses a kind of leather dyeing methods of appliable plant primary colour dye.Including dyeing liquor preparation, dyeing, softening, fixation, the several key steps of sealing wax, blue dyeing liquid, yellow dyeing liquor and red staining liquid are prepared in dyeing liquor preparation step, then by one of blue, yellow and red staining liquid or more than one be hybridly prepared into the dyeing liquor of required color, the sap that tung tree fruit squeezes slowly is boiled before this in staining procedure, transparent bright oil is made, the transparent colored varnish will be made after the raw lacquer extracted from lacquer tree purification, bright oil and the colored varnish are mixed, it is added in dyeing liquor, plant primary colour dye is made；Then the leather lanthanum nitrate-citric acid complex solution that need to be dyed is turned into certain time in rotary drum；Coating colouring is carried out to the above-mentioned leather by rare earth mordant dyeing with plant primary colour dye again, in rotary drum transfer certain time after colouring, completes dyeing.Leather dyeing method of the invention is environmentally protective, and color fastness is high, is not easy to fade.
Description
Technical field
The present invention relates to leather coloring field, more particularly to a kind of leather coloring of appliable plant primary colour dye
Method.
Background technique
Leather is widely used in the industries such as shoemaking, fur clothing, leather goods, fur and its product, and leather on the market includes true
The different type such as skin, regenerated bark, artificial leather, synthetic leather, either corium or artificial leather are all single before without dyeing
One color, these single leather processings are unable to satisfy people for the vision requirement of color at different products, therefore,
The relevant industry of leather handles the surface of leather by dyeing, is then reprocessed into colorful leather products, skin
It is rich in color, beautiful after leather dyeing, it can more obtain the favor of consumer.
Dyestuff used in leather coloring is generally the chemical dyestuff synthesized, belongs to the dyestuff of aromatic amine, aromatic amine mostly
Substance mostly can be carcinogenic, and synthetic dyestuffs have attracted more and more attention from people in production with the problem of environmental pollution in application process,
Many advantages, such as natural dye is environmentally protective with its, safe and non-toxic obtains the attention of people again.
Natural plant dyestuff is to use the substance extracted from coloured plant petals, fruit, dry, root, leaf etc.
Such as red to extract from the petal of safflower in dyestuff, yellow can be extracted from the fruit of cape jasmine or the sap of gamboge, and blue can
It is subordinated to doing and extracting in leaf for the indigo plant of polygonaceae, the root of the orange-yellow Radix Curcumae for being subordinated to Zingiber and dry middle extraction, but use
The staining technique of vegetable matter according to the difference of dye materials using unique staining technique the disadvantage is that, can only be contaminated
Color, colouring method is different due to the difference of raw material, therefore inconvenience very troublesome, and vividness is easy to fall off thinning, can be because continually
Washing causes to fade, decolourize.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of leather of appliable plant primary colour dye
Colouring method, environmentally protective, color fastness is high, is not easy to fade.
To achieve the above object, the present invention provides the following technical scheme that a kind of leather of appliable plant primary colour dye contaminates
Color method comprises the following specific steps that:
Step 1: prepared by dyeing liquor:
(1) it prepares blue dyeing liquid: using woaded blue as raw material, gooseberry being added to be made through everfermentation；
(2) it produces yellow dyeing liquor: the bark of Chinese corktree being ground into phellodendron powder, water is added to mix, with citric acid-lemon
Sour sodium buffer adjusts its pH, then extracts to obtain yellow dyeing liquor through cellulase catalytic；
(3) it produces red staining liquid: Schisandra fruit Soakage extraction being obtained into preliminary dye liquor, adds safflower fine powder and purple
Red staining liquid is made in grass meal；
(4) by one of the blue of above-mentioned preparation, yellow and red staining liquid or needed for more than one are hybridly prepared into
The dyeing liquor of color；
Step 2: dyeing:
