Abstract
The invention discloses a kind of preparation methods of the regenerated celulose fibre containing natural dye, specifically the natural dye collosol and gel being prepared using sol-gal process is made after being mixed with rayon spinning liquid after dispersion liquid and carries out wet spinning, regenerated celulose fibre is made.Original liquid coloring fiber produced by the present invention has preferably every color fastness, while having better feel, solves the problems, such as that current natural dye is taken by unqualified the brought production of every color fastness.
Description
Technical field
The present invention relates to textile industry raw material and its manufacturing methods, and in particular to a kind of regeneration containing natural dye
The preparation method of cellulose fibre.
Background technology
Natural dye is broadly divided into three categories：Natural plant dye, natural animal dyestuff and natural mineral matter dyestuff.Naturally
Vegetable colour mainly extracted from the root of various plants, leaf, stem and fruit, bark and flower, as ginger, pomegranate, it is indigo,
Yellow Fructus Gardeniae, tea tree, mulberry tree etc.；The type of natural animal dyestuff is less, usually extracted from cochineal and shellfish and
Come, such as kermes, shellac, alkermes；Natural mineral matter dyestuff is the colored inorganic object extracted from various mineral
Matter, such as manganese brown, chrome yellow, ultramarine.
In recent years, part chemical dye containing toxic component because that can cause skin allergy occur, redness, inflammation, suppurate
Symptom or even some chemical dyes contain carcinogen；Simultaneously at present the raw material of many chemical dyes all derive from coal and
Oil.Coal, oil are more in many sector applications, and consumption is very fast, non-renewable, and excessive use can cause resource exhaustion；And
And the treatment of dyeing wastewater difficulty that chemical dye generates in dyeing course is larger, cost is higher, is not easy to recycle, and is easy to make
At environmental pollution.And natural dye is environmental protection, healthy dyestuff, biological degradability is good, good with ecological environment compatibility, and
Nontoxic, to no skin irritation and carcinogenicity, and its source is renewable, while natural dye dying waste water not will produce
The water pollution problems that waste water from dyestuff is caused is learned, the intractabilities such as waste water decoloring are smaller, have good research and development foreground.
But that there is also dye-uptakes is low, every color fastness is low and expensive etc. many for the dyeing of natural dye at present
The relatively low problem of disadvantage, especially color fastness, significantly limits the application of natural dye.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of regeneration safe and environment-friendly, that color fastness is excellent is fine
The preparation method of cellulose fiber, by the spinning solution that adds natural dye after sol-gel technique coats, spinning system
Obtain the regenerated celulose fibre with preferable properties.
The present invention realizes in the following way：
A kind of preparation method of the regenerated celulose fibre containing natural dye, includes the following steps：
Step 1, the preparation of rayon spinning liquid；
Step 2, the natural dye sol-gel and dispersant that are prepared using sol-gel method, solvent are mixed,
Obtain natural dye sol-gel dispersion liquid；
Step 3, after natural dye sol-gel dispersion liquid being mixed with rayon spinning liquid carry out wet spinning to get.
Further, sol-gel method described in step 2 is first that the mixing of metal alkoxide, solvent and natural dye is laggard
Row hydrolysis condensation reaction, then colloidal sol obtained is aged to obtain wet gel, it is then freeze-dried, natural dye is obtained after crushing
Sol-gel.
Further, metal alkoxide is silicon ethyl alcohol or isopropyl titanate in the step 2.
Further, the solvent is ethyl alcohol, isopropanol or butanol.
Further, the natural dye is natural plant dye or natural minerals dyestuff, and natural plant dye is selected from madder
Grass, safflower, Asian puccoon, bush, indigo, pomegranate, Yellow Fructus Gardeniae, tea, Song indigo plants, hispid arthraxon, persimmon, Asian puccoon or ink tree extract, day
Right mineral dye is selected from cinnabar, malachite green, copper oxide or ferroso-ferric oxide.
Further, the mass ratio of metal alkoxide, natural dye and solvent is 10~20:5~10:70~85.
Further, the mass fraction of natural dye sol-gel is in the natural dye sol-gel dispersion liquid
10%~
20%, solvent is water.
Further, the dispersant is one kind in calgon, tristerin or stearate, dosage
It is the 1%~3% of natural dye sol-gel mass fraction.
Further, the grain size of the natural dye sol-gel is 0.1~1 μm.
Further, in step 3 dosage of natural dye sol-gel account for first fibre content in rayon spinning liquid 10%~
15%.
Heretofore described first fibre refers to：Alpha cellulose is also known as alpha-cellulose.Cellulosic material is dipped at 20 DEG C
In 17.5%~18% sodium hydroxide solution after 45 minutes undissolved part.
The present invention utilizes the principle of sol-gel cladding, and natural dye sol-gel powder is made after natural dye is coated
The regenerated celulose fibre of original liquid coloring is prepared afterwards with viscose rayon spinning solution co-blended spinning in end.With utilize natural dye
The fiber of dyeing is compared, and original liquid coloring fiber of the invention has preferably every color fastness, while having better feel, solves
Current natural dye determined since problem is taken in unqualified the brought production of every color fastness.In addition, using sol-gel by day
The form and aspect and color and luster of natural dye are not influenced not only after right coating dye, while natural dye can also be protected from external environment
The variation of color and luster and form and aspect caused by destruction, such as the acid-fast alkali-proof of natural dye are poor, especially the spinning of viscose rayon
Silk process concentrated acid concentrated base can seriously destroy natural dye structure, lead to dye discoloration or colour killing, and utilize sol-gel by day
After right coating dye, it can both ensure that dye structure is not destroyed, and not will produce discoloration, the form and aspect and color of dyestuff will not be changed
Light is more conducive to the use condition and application range for widening natural dye, improves current natural dye and is limited by various conditions
The case where processed.
