Description
Technical field
The invention belongs to colouring art, more particularly to a kind of preparing rose extracting stock solution is dyed cloth the method for material.
Background technology
Plant dyeing refer in dyeing course without using or seldom use chemical assistant, and use is obtained from the Nature
Vegetable dyes, a kind of technique dyed to product.Plant dyeing is with a long history, but the modern times are due to chemical synthetic dye
Be easy to largely produce, cost is low, has gradually captured most dyeing market.But wherein contain many harmful substances, endanger
Human health, pollutes environment.
Plant dyeing have accumulated the experience and wisdom of many forefathers, these excellent Color Cultures should be endowed new meaning
Justice, will not just make culture form fault-layer-phenomenon；Plant dyeing can not only obtain various bright-coloured high chroma colors, can more obtain
A large amount of fine and smooth Neutral colour, and redying through different numbers and different form and aspect, can dye more rich meaningful color layer
It is secondary；The characteristics of plant dyeing, is the continuous utilization of natural resources, while can be to avoid the serious pollution problem of chemical dye；With
The increasingly raising of people's living standard, pay attention to day by day environmental protection, pursues health care, the market demand of plant dyeing is more next
More urgent, the demand of particularly high-end market has shown.
And existing plant dyeing generally refers to extract phytochrome by way of heating boiling, so very likely can
Pigment composition is destroyed in itself and its efficacy effect, so that not reaching expected plant dyeing target.Such as：Chinese patent
CN105780530A discloses a kind of rose cloth dyeing technology, takes rose, the water of 1~30 times of weight is added, in 100 DEG C of water
Boil 30 minutes~2 it is small when after, be filtered into coloring agent liquid.But the mode of its thermophilic digestion makes loss of effective components in rose
Greatly, staining efficiency is low.
On the other hand, pigment is dissolved, separated by the prior art also by various extracting process from animal, plant or mineral chapter
Out, during but due to extraction natural pigment, other water soluble ingredients in natural dye is contained in and also are extracted out together, are caused
The pigment composition of natural dye is extremely complex, the affine force difference between fiber, washable, wear-resisting, sunlight fastness is poor.
Therefore, it is badly in need of providing a kind of simple, efficient natural plant dye colouring method.
The content of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of method that preparing rose extracting stock solution dyes cloth material, this method
Compared to the active ingredient that traditional heating means can retain rose stoste comprehensively, coloring and health aspect effect are more preferable, because of rose
Rare flower has high medicinal health value, and the cloth dyed, when human body is worn, is very beneficial for health.After dying cloth
The water of discharge does not have environment any pollution, very environmentally friendly.This method technological design is reasonable, operation easy to implement.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of preparing rose extracting stock solution is dyed cloth the method for material, including：
1) by roseleaf alcohol extracting, separation of solid and liquid, rose filtrate；
2) above-mentioned rose filtrate is purified with molecular sieve film, filtrate is collected, up to rose extracting thing；
3) rose extracting thing is uniformly mixed with water, light-coloured vinegar, obtains rose coloring agent；
4) cloth dyed, is dehydrated using above-mentioned rose coloring agent, rear mordant dyeing, be dehydrated, dry in the shade, to obtain the final product.
Existing rose pigment is generally obtained using alcohol extracting method, but the application research is found：Rose pattern after alcohol extracting
Element still contains partial impurities, if being used to dye directly as coloring agent, can cause affine force difference between fiber, sun-resistant jail
Spend the problems such as poor.The present invention purifies the rose pigment after alcohol extracting, and by the staining method of mordant dyeing twice, obtains
Preferably coloring was obtained, the sunlight fastness of cloth significantly improves after dyeing.
Preferably, in step 1), the rose is the Flos Rosae Rugosas pollen after lyophilized, crushing.
Preferably, in step 1), the condition of the alcohol extracting is：By rose pH value be 2.5 or so, mass concentration 65
In~70% ethanol solution, 35~40min is soaked.
Since the complicated and specific species of impurity component after rose alcohol extracting is unknown.In order to obtain preferably refining effect,
The present invention has attempted a variety of way of purification such as extraction, UF membrane, solid absorption method, chromatography, dialysis, finds：Cellulose acetate film
Nanofiltration is carried out to rose extract, the higher rose extracting liquid of purity can be obtained, and filter method is simple.
Therefore, in step 1), currently preferred separation of solid and liquid is centrifugation.
Preferably, it is described to cure separated temperature as 0-5 DEG C in step 1).
Preferably, the molecular sieve film is cellulose acetate film.
Since rose is natural plant dye, direct staining is difficult pigment is determined in fiber, is caused washable, resistance to
Mill, poor color fastness.For this reason, the present invention attempts to improve its color fastness by way of adding mordant, chanced in research：With
The prior art individually using first mordant dyeing, rear mordant dyeing, middle mordant dyeing or altogether bath mordant dyeing compare, be total to using acid mordant and iron mordant
Bath mordant dyeing can effectively improve the staining efficiency of rose extracting liquid, can obtain different face by the change of soaking time
Color, and with preferably pigment stability and color fastness.Therefore, preferable dye liquor composition is in the present invention：Water, light-coloured vinegar, rose
The mass ratio of flower extract is 10:3:1.
Preferably, the mass ratio of the cloth and dye liquor is 1:20.
Preferably, during the rear mordant dyeing, mordant is by iron rust, acetic acid, water with 1:2:2 weight ratio mixes.
Preferably, the cloth is pure cotton cloth, crudefiber crop or cloth of real silk.
Beneficial effects of the present invention
(1) rose liquid reactive extract of the invention has antibacterial, and whitening function, is dyed cloth with extract, institute
Material of dying cloth is very beneficial for health, and environment is polluted without draining after dyeing.
(2) preparation method of the present invention is simple, staining efficiency is high, highly practical, easy to spread.
