Description
Technical field
The present invention relates to silk fabric technical field, in particular to dyeing side of a kind of dye yam extracting solution to silk fabric
Method.
Background technique
Dye yam (scientific name: Dioscorea cirrhosa Lour.) is Dioscoreaceae, and Dioscorea liana is long up to 20
Rice.Stem tuber crust dark brown, uneven, red when section is fresh, stem green, hairless, single blade, keratin or nearly keratin, top
Tapering or rapid point is held, basal circular, two sides is hairless, surface bottle green, back side powder green, and net vein is obvious；Dioecism.Male inflorescence
For spike, reflexed, nearly triangular-shaped oblate, seed are not born in the middle part of every room axis capsule, and surrounding has film quality wing.4-6
Month bloom, January in July to next year result.
Be distributed in Zhejiang Province, China south, South Jiangxi, Fujian, Taiwan, Hunan, Guangdong, Guangxi, Guizhou, South Sichuan and
Western part, Yunnan, Motuo In Xizang.Vietnam is also distributed.It is born in 350-1500 meters of height above sea level of hillside, the shaw in roadside, river valley side
In, in broad-leaf forest, in shrubbery or woods side.This kind of stem tuber is rich in tannin, can obtain through refining tannin extract, or is used as dye silk, cotton, fishnet.
The conventional process flow of gambiered Guangdong gauze: dye yam is washed, water shutoff, is dried, is crossed mud, wash, dry, spreading out mist.Production procedure is multiple
It is miscellaneous, and be manual operations, labor intensity is very big, and production procedure is long, and consumption raw material is more, cost is high.Thus it is badly in need of to biography
The dye yam extracting solution dyeing of system is improved, and is changed its manual production low output, can only be measured the statuses such as uncontrollable, is realized
Industrialized production.
In recent years, the research of supercritical fluid printing technology gradually causes the concern of people.Supercritical fluid dyeing technology
Be using certain fluid in the supercritical state to fiber have stronger swelling action and to certain dyestuffs have preferably
Solubility property, can making dyestuff under anhydrous conditions, quickly upper dye is a kind of novel to realize to stock-dye in fiber
The waterless staining technique of environmental protection.
Summary of the invention
The purpose of the present invention is being directed to technological deficiency existing in the prior art, a kind of dyeing side of silk fabrics is provided
Method carries out colour developing fixation by supercritical carbon dioxide, avoids natural dye Degradation and Transformation in dyeing course, and after pressure release
Carbon dioxide will not carry coloring agent, therefore, in reaction kettle and pipeline without coloring agent pollute, so replacement coloring agent
When, it is not necessary to coloring system is cleaned, so that and coloring system need not be cleaned.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of colouring method of dye yam extracting solution to silk fabric, comprising the following steps:
S1, dye yam extracting solution is added a certain amount of mass concentration be 10~15% soluble iron salting liquid and adjust pH value
It is 5~6, obtains dye solution；
S2, silk fabric is placed in dye solution obtained by step 1) and is dyed；
S3, the silk fabric after dyeing is transferred in reaction kettle, is then passed through titanium dioxide into the reaction kettle
Carbon, the pressure for controlling the reaction kettle is 8~15MPa, and temperature is 35~40 DEG C, so that the fluid in the reaction kettle is super
Critical carbon dioxide fluid；
S4, after the silk fabric develops the color fixation 2~3 hours in the reaction kettle, the reaction kettle is let out
Pressure, and the reaction kettle is opened after the completion of pressure release, the silk fabric after taking out colour developing fixation.
The extracting method of the dye yam extracting solution is as follows:
1) coarse extraction: fresh dye yam root is crushed, and the pectase for being equivalent to dye yam root weight 0.1%~0.3% is added
With the hemicellulase for being equivalent to dye yam root weight 0.9%~1.6%, enzymolysis processing obtains enzymolysis liquid at 25~40 DEG C, by enzyme
It solves liquid and zymoprotein inactivation is carried out using ultra high pressure treatment, then the raw material after obtaining super-pressure inactivation treatment is added a certain amount of
Distilled water simultaneously stirs evenly, and high-pressure homogenization is handled 1~3 hour, obtains homogenate；
2) it is then handled 6~10 minutes in the case where output power is the microwave condition of 600W, with ethyl alcohol-surfactant in temperature
Degree extracts 2~5 times under the conditions of being 70~90 DEG C, and stirring, collects leaching liquor at centrifugation；
3) leaching liquor is successively passed through to plate-frame filtering, ultrafiltration membrance filter, collects the filter that molecular cut off is greater than 50000Da
Liquid, as dye yam extracting solution.
Further, the pressure of step 1) the high-pressure homogenization processing is 60MPa, and the time is 1 hour.
Further, surfactant described in step 2) is selected from polyoxyethylene sorbitan monolaurate, polyoxy second
Alkene sorbitol anhydride monopalmitate, polyoxyethylene sorbitan monostearate and Tween-80
In the mixing of any one or more.
Further, the ethyl alcohol-surfactant mixing leaching liquor the preparation method comprises the following steps: to concentration of alcohol be 50~
The surfactant of 0.2~2wt% of ethanol water gross mass is added in the ethanol water of 80v/v%.
Further, homogenate and ethyl alcohol-surfactant mixing leaching liquor mass ratio are 1:5~1 in step 2):
30。
Compared with prior art, the colouring method of a kind of silk fabric of the invention has as follows
The utility model has the advantages that
1) operation of the present invention is simple, and the silk fabric after dyeing is placed in supercritical carbon dioxide fluid and is developed the color
And fixation, since supercritical fluid remains static, in colour developing laking process, transport phenomena will not occur for coloring agent, dye
Chromaticness amount is easily controllable, and the carbon dioxide after pressure release will not carry coloring agent, therefore, without coloring agent in reaction kettle and pipeline
Pollution, so when replacing coloring agent, it is not necessary to clean coloring system.
2) the curcumin purity that the present invention extracts is up to 99% or more, especially suitable for days such as silk fabric, wool fabrics
The dyeing of right fabric.
