Description
Technical field
The present invention relates to a kind of ether alcohol class carrier dyeing method of polyimide fiber and fabric, belong to textile auxiliary
With textile dyeing and finishing manufacture field.
Background technology
Polyimide fiber is a kind of Aramid fibers, has all kinds of excellent properties of high-performance fiber.Compared to other
High-performance fiber, polyimides have more preferable integrated application performance, available for all kinds of protective clothes are developed, can also be applied to navigate
The special application fields such as empty space flight, military affairs, there are very big market prospects.Polyimide fiber is golden yellow, and color is excessively fresh
Bright, this very big application for limiting polyimides, polyimides, which is dyed, to be extremely necessary.But polyimide fiber knot
Structure is regular, and heat endurance is good, and glass transition temperature is very high, therefore dyeing is limited by very large.The dyeing of polyimides at present
Method is nothing more than two kinds：Fibre modification poststaining and carrier dyeing.Modified poststaining is not mainly alkaline-resisting using imide structure
Characteristic.Polyimide fiber can hydrolyze generation polar group in the basic conditions, and such polar group can be with dyestuff knot
Close, but after fiber is hydrolyzed, destroy the original regularity structure of polyimide fiber, the strength loss of fiber can be made serious,
Lose the meaning of high-performance fiber.Carrier dyeing is to the molten of fiber by the Small molecule organic solvents close with fibre structure
Swollen effect, carrier layer is formed in fibrous inside and fiber surface, recycle the dissolubility of dyestuff in a solvent, dyestuff is constantly entered
Enter the inside of fiber so as to reach the purpose of dyeing.
The existing dyeing on polyimides is mostly that fiber surface is modified, such as patent CN201310493553.0,
CN201610393927.5 and CN201510896425.X etc. is to carry out surface treatment poststaining, Color to polyimides
It is good, but processing method is complicated.CN201510623413.X dyes use dyeing accelerant to polyimides.The selection of dyeing accelerant is profit
With solubility parameter principle, by theoretical calculation, compounded by the organic solvent of several different solubilities parameters.Patent
CN201710342615.6, which is used, contains amide-type organic solvent as polyimides dyeing carrier, but it is imitated as carrier
Fruit is unsatisfactory, it is difficult to contaminate dark, and also such carrier does not do single research in terms of polyimides dyeing, is led in weaving
Domain is also used for the dyeing of the compounding class carrier of synthetic fibers.
It is therefore desirable to development approach is easier, the more preferable colouring method of effect.
The content of the invention
In order to solve the above problems, the present invention provides a kind of ether alcohol class carrier dyeing side of polyimide fiber and fabric
Method.The inventive method, directly using qualified carrier, without calculating its solubility parameter, method is easy；The present invention uses
Carrier be phenylate class, benzene alcohols, Color is good compared with amide-type carrier, and the tinctorial yield of fabric is higher after dyeing, and fabric can be with
Deeper color is obtained, and washing fastness is good.
Shown in polyimides dyeing carrier structure provided by the present invention such as formula (1) or formula (2)：
Wherein, in formula (1), R1For any one in hydrogen, alkyl, aryl, alcohol alkyl；R2, R3, R4, R5, R6For hydrogen, alkane
Any one in base, aryl, alkoxy, hydroxyl；
Wherein, in formula (2), R1For alkylidene；R2, R3, R4, R5, R6For hydrogen, alkyl, aryl, alkoxy, hydroxyl.
The present invention also provides a kind of method dyed to polyimide fiber or fabric, and methods described is to apply this hair
Any one in bright ether alcoholic vehicle or multiple combinations.
In one embodiment of the invention, the dyestuff used that dyes is the dye of positive ion.Inventor also attempts
The dyestuff of other classes is crossed, dye of positive ion effect is preferable.
Methods described, comprise the following steps：
Step 1, remove polyimide fiber or the oily impurity of fabric face attachment；
Step 2, the polyimides after the removal of impurity will be gone to be added in the dye liquor containing the dye of positive ion and the carrier,
Dyed；
Step 3, polyimides is washed to remove dyeing loose colour after the completion of dyeing.
In one embodiment of the invention, step 1, polyimides, which adds, contains 2-3g/L non-ionic surfaces surface
In the solution of activating agent, bath raio 20-30:1,30-60min is handled at 85-95 DEG C, fully naturally dry after washing.
In one embodiment of the invention, the non-ionic surface surfactant is non-ionic surface surface-active
Agent AEO-7.
In one embodiment of the invention, the step 2, will go the polyimides after the removal of impurity be added to containing
In the dye liquor of carrier and the dye of positive ion, the bath raio of dye liquor and fabric is (15:1)~(30:1)；The dye of positive ion
It is 2.5%-10% to fabric weight (owf)；
In one embodiment of the invention, the carrier is the one or more of compounding of the carrier in the present invention, is carried
Bulk concentration is 10-100g/L.
In one embodiment of the invention, the step 2, will go the polyimides after the removal of impurity be added to containing
In the dye liquor of carrier and the dye of positive ion, 120-130 DEG C is warming up to 1.5-3 DEG C/min speed, is incubated 40-120min；It is complete
70-80 DEG C is cooled to 2-3 DEG C/min speed after, ensures that dyestuff is fully upper and contaminates.
In one embodiment of the invention, the washing of the step 3 is first to wash, soap, finally wash again.
In one embodiment of the invention, the step 3, after the completion of dyeing by polyimides be added to containing from
In the solution of soaping of sub- surfactant, for example, AEO-7, bath raio 20:1-30:1, filled after handling 15-30min at 85-95 DEG C
Divide washing.
