Description
Technical field
The present invention relates to textile technology field, in particular to a kind of brazilwood vegetable dye and its textile fabric coloring agent group
Close object.
Background technique
" textile industry scientific and technological progress development outline " proposes: the development and application of environmental protection type dye are that development textile printing and dyeing is novel
The task of top priority of technology, directly affects enterprise competitiveness and benefit, it has also become hinders the bottleneck of dyeing industry development.It spins now
Knitting the dyestuff that printing and dyeing enterprise uses is essentially all chemical dye, and chemical dye was born in Britain in 1846, by coloring jail
It spends, quick advantage of printing and dyeing, soon instead of the natural plant dye for having adopted thousands of years after successor China.But
Be with chemical dye pollution environment, it is unhealthful the problems such as gradually show, natural plant dye is with its distinctive green ring
Guaranteed cost becomes the hot spot and research direction of stakeholder in the industry and enterprises pay attention again.Natural plants dyeing is a Gu
Old textile dyeing, dye source used can generally drop naturally in the root of plant, stem, leaf, flower, fruit etc., pigment
Solution, therefore have the characteristics that nonhazardous, free of contamination, many chemical dye brings harm are avoided, it is simultaneous with good environment
Capacitive.And many natural plant dyes have antibacterial, anti-inflammatory, health care and other effects due to its own as middle medicinal herbs.?
Today back to nature social theme in, using natural plant dye exploitation health environment-friendly product catered to textile printing and dyeing product to
Ecology, environmental protection, health, comfortable and function sexual development trend.
Traditional plant dye most common problem of textile fabric is exactly that color fastness is not ideal enough, according to existing research,
On the one hand reason is that the unstable chromophoric group of vegetable colour reduces its washable and color fastness to light, on the other hand, plant dye
The pigment of material also affects it to fabric color after dyeing from different plant, and with environment, geography, the difference in season
The stability of fastness and the reproducibility of color.
Summary of the invention
The purpose of the present invention is being directed to technological deficiency existing in the prior art, a kind of brazilwood vegetable dye and its spinning are provided
Knitted fabric coloring composition is not only good to the coloring effect of textile fabric but also harmless.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of textile fabric brazilwood vegetable dye, which is characterized in that preparation method the following steps are included:
1) it will be put into extraction kettle after bush dry powder, be passed through supercritical methanol as extractant, ammonium hydroxide is added as entrainment
Agent, extraction temperature are 20~25 DEG C, 6~7MPa of extracting pressure, and extraction time is 10~15 minutes, and methanol flow rate is 1~10L/
H, 0.1~0.55ml/min of entrainer flow velocity；
2) supercritical methanol containing extract is depressurized, to isolate extraction product, 10~20 DEG C of separation temperature,
Separating pressure is 1~5MPa, collects resulting extract liquor；
3) it is concentrated into paste, upper macroreticular resin is successively washed till clarification of water with the ethyl alcohol of water, 5~10%, finally uses 80-
85% ethanol elution, eluent ethyl alcohol of going out obtain concentrate A；
4) it will be filtered after concentrate A alcohol solvent, filtrate mixes sample, upper polyamide chromatography column, using volume with polyamide
Ratio is that 10:1~1:1 water and methanol mixed solution carry out gradient elution, and collect water: methanol is that 8:1~5:1 eluent is concentrated to give
Concentrate B, then by concentrate B freeze-drying after to obtain the final product.
Use ammonium hydroxide that can improve solvent of the hematoxylin in supercritical solvent as entrainer with extremely low dosage
Degree, greatly reduces the usage amount of supercritical solvent, improves extraction efficiency and increase the amount of precipitation of hematoxylin.
It further, further include the preparation step of bush dry powder, the preparation step of the bush dry powder before step 1) are as follows:
Vacuum freeze drying processing will be carried out after bush stripping and slicing, then the Chinese aloe leaf after drying process is crushed, is sieved.Further
The drying temperature on ground, the vacuum freeze drying processing is -30~-50 DEG C, and drying time is 10~20 hours, the sieving
Sieve is 30~50 mesh.
Further, extraction temperature described in step 1) is 25 DEG C, extracting pressure 6MPa, extraction time 10min, first
Alcohol flow velocity is 6L/h, entrainer flow velocity 0.2ml/min.
Macroreticular resin is D-101 type or AB-8 type in step 3).
Another aspect of the present invention also provides a kind of textile fabric coloring composition, wherein preparing institute comprising the above method
The brazilwood vegetable dye obtained, content are calculated by weight as 10~15 parts.
Further, the textile fabric coloring composition also includes following component: diphenyl ether tetracid dianhydride 8~
10 parts, 2~5 parts of polypropylene glycol, 18~20 parts of mica powder, 2~5 parts of zinc stearate, 7~10 parts of ethyl triethoxysilane, carbon
4~7 parts of sour sodium, 3~5 parts of ethyl alcohol, 40~45 parts of water, 5~8 parts of polyvinylpyrrolidone.
Further, the textile fabric is silk.
Compared with prior art, a kind of textile fabric coloring agent of the invention, has the following beneficial effects:
1) in brazilwood vegetable dye's extraction process, use ammonium hydroxide that can improve Soviet Union as entrainer with extremely low dosage
Solvent degree of the wooden pigment in supercritical solvent, greatly reduces the usage amount of supercritical solvent, improves extraction efficiency and increase
The amount of precipitation of hematoxylin is added.
2) present invention is reasonably matched by plurality of raw materials, to realize that colouring is simply contaminated with fabric not easy to fade
Toner, the present invention can improve the color fastness of fabric, and color stability after dyeing will not also influence artificial adult body.
