0.5kg wormwood extract is packed into natural plant dye kettle.
2, prepared by supercritical carbon dioxide
The liquid carbon dioxide being stored in liquid carbon dioxide storage tank is injected into CO 2 high pressure pump by pipeline
In；In high-pressure pump, by carbon dioxide pressurization to 8MPa, its temperature is heated to 90 DEG C using preheater and obtains overcritical two
Carbonoxide.
3, natural plant dye extracts
Supercritical carbon dioxide fluid made from step 2 is injected separately into natural plant dye extraction kettle from preheater
In natural plant dye kettle, a part of supercritical carbon dioxide extracts vegetation color in natural plant dye extraction kettle former
Material carries out extracting obtained supercritical extract dyestuff, and another part supercritical carbon dioxide comes into full contact with natural plant dye to be mixed
Supercritical solvent dyestuff is made, supercritical extract dyestuff is prepared simultaneously with supercritical solvent dyestuff, improves dyeing efficiency, shortens dye
The color time.
4, function modified
Dyeing caldron is subjected to heating pressurization, the temperature in kettle to be dyed reaches 90 DEG C, pressure is when reaching 30MPa, passes through extraction
It takes kettle automatic pilot that quickly natural plant dye extraction kettle opening mixes with supercritical carbon dioxide and overcritical extraction is made
Dyestuff is taken, by supercritical solvent dyestuff in the supercritical extract dyestuff and natural plant dye kettle of preparation according to constant weight ratio
It is circulated in injection dyeing caldron, circulation time 10min, carries out dyed blended, dyed blended time 120min after circulation.
5, last handling process
After dyeing, supercritical carbon dioxide is through separator and dye separation, at this point, the temperature of separator is 80 DEG C,
Pressure 3MPa, after separation, carbon dioxide becomes gaseous state and enters in condensation kettle, and dyestuff then stays in separating still；
The temperature of the condensation kettle is 20 DEG C (room temperature), and pressure 4MPa, gaseous carbon dioxide is changed into liquid carbon dioxide,
It is then refluxed for entering in liquid CO 2 storage tank, participates in modified technique next time, be recycled；Dyeing caldron is opened, will be changed
Property after natural fiber take out.
6, it cleans
The liquid carbon dioxide being stored in liquid carbon dioxide storage tank is injected into CO 2 high pressure pump by pipeline
In；In high-pressure pump, by carbon dioxide pressurization to 7.382MPa, its temperature is heated to 65 DEG C using preheater, will be preheated
Device is connected directly with dyeing caldron, and dyeing caldron is heated to 65 DEG C, and lytic agent is added in dyeing caldron, starts the stirring in dyeing caldron
Device stirs 5min, after the fluid after stirring is passed through separator for carbon dioxide and dye separation, at this point, separator
Temperature is 80 DEG C, pressure 2MPa, after separation, and carbon dioxide becomes gaseous state and enters in condensation kettle, and dyestuff then stays in separating still, pipe
Dyestuff in road is cleaned, and does not influence the dyeing of dyestuff next time；Dehydrated alcohol and ethyl acetate in the lytic agent
Mass ratio be 2:13.
In the present embodiment, using the supercritical CO 2 dyeing system of embodiment 1, wherein in the dyeing caldron of the system
Inner wall is equipped with 0Cr18Ni9 coating, and 0Cr18Ni9 coating not only has the function of the antiacid alkali of antirust, while can be significantly
Attachment of the dyestuff to coloring system inner wall is reduced, through overtesting, in the immovable situation of the other equipment of 1 coloring system of embodiment
Under, if not using 0Cr18Ni9 coating in overcritical dioxy carbon coloring system dyeing caldron, in cleaning step, need continuously to being
System inner wall washing 3 times or more, and need 20min or more to can be only achieved the condition for dyeing and using next time every time, i.e., it does not generate mixed
The phenomenon that color；If overcritical dioxy carbon coloring system dyeing caldron uses 0Cr18Ni9 coating, it is only necessary to continuously to system inner wall
Cleaning 1 time, 5-10min can be cleaned and be finished.
In order to further select the mixing of best extraction dyestuff and natural dye, to reach last to fiber or fabric
Dyeing effect, the present invention carried out following tests:
Using the coloring system and dyeing of embodiment 1 and embodiment 2, only change plant petals type in dyeing
With the type of natural extraction feed, after the completion of dyeing, the fiber or fabric complete to dyeing carry out cleaning test, to find
The best combination of color performance；
Test raw material:
Natural cotton fiber is as pollutant；
Plant petals: roseleaf, safflower spend the one or more of petal, rape petal, Ladanum petal after wood；
Plant leaf blade: the one or more of Boehmeria nivea leaves, Folium Ginkgo；
Natural plant dye: mint extract, wormwood extract；
Plant leaf blade and plant petals form three primary colors, main to provide the source of dyestuff；Natural plant dye mainly provides
It is functional.
Cleaning method:
After dyeing, pollutant is dried into 100-120min, is dried again after being washed out, after observation washing 10 times, observation
Pollutant washing front and back color change situation；
Washing methods are as follows:
Liquid detergent: fiber=0.25:100, water cover fiber, carry out hand rubbing washing, each 20min, dehydration to fiber
5min, is then added last time equivalent clear water, and hand rubbing washing washes 5min, is dehydrated 5min.
Testing index:
The coloration rate of descent and antibiotic rate of pollutant after washing.
Specific detection case, is shown in Table 1
Table 1
As can be seen from the above table, on the whole, in plant extracts wormwood extract in conjunction with vegetation color extraction feed
Afterwards, whole larger to the contribution of fiber color fastness, the especially combination of rape petal and wormwood extract, coloration almost changes not
Greatly, therefore washing color fastness is best, while antibiotic rate is also relatively high, has good anti-microbial property, wherein anti-microbial property
The best combination for Folium Ginkgo and wormwood extract of group.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
