Description
Technical Field
The invention relates to a ketone-ester carrier dyeing method for polyimide fibers and fabrics, belonging to the fields of textile printing and dyeing auxiliaries and textile dyeing and finishing processing.
Background
Polyimide is a novel high-performance fiber, and has excellent performance of various high-performance fibers, and also has better thermal stability and flame retardance. However, the polyimide fiber has natural golden yellow color, is bright in color and cannot be removed, so that great difficulty is brought to dyeing, and the dyeing difficulty is increased due to the high glass transition temperature of the polyimide fiber. The main dyeing methods at present are modified dyeing and carrier dyeing, wherein the modified dyeing research is more extensive. The modified dyeing is to utilize the weak alkali resistance of the polyimide fiber, and increase polar groups on a molecular chain after the fiber is treated by alkali liquor, thereby achieving the purpose of dyeing, but the method destroys a cyclic structure on a fiber macromolecular chain and can affect other properties of the fiber. Carrier dyeing is widely researched on other synthetic fibers such as polyester, aramid and the like, but is less in the aspect of dyeing of polyimide fibers, proper carriers need to be screened continuously, carrier dyeing is that a carrier layer is formed inside fibers and on the surfaces of the fibers by utilizing the swelling effect of an organic solvent on the fibers, and the dyes continuously enter the fibers by utilizing the solubility of the dyes in the solvent so as to achieve the purpose of dyeing.
The current dyeing of polyimides is mainly focused on post-modification dyeing of fibers and carrier dyeing. Among them, patents CN201310493553.0, CN201610393927.5, and cn201510896425.x are all used to dye polyimide with the help of a certain assistant after surface treatment. Patent CN201510623413.X only uses carrier (dye-guiding agent) to dye polyimide, but not to modify fiber, the invention utilizes solubility parameter theory to calculate the combination of several different organic solvents to be the same as the solubility of polyimide, the method is feasible, but the calculation process is complicated, the types of solvents are various, and the deletion is not based on the available basis. Patent CN201710342615.6 uses amide-containing carrier to dye polyimide, but it is difficult to dye polyimide with dark color.

The color parameters and wash fastness of the dyed samples are shown in table 1.
TABLE 1 CIE Lab, K/S, wash fastness progression and Strength of the dyed polyimide Fabric support
Note: determining color change fastness and staining fastness according to the textile color fastness test standard GB/T3921-2008; the breaking strength is the yarn strength, and is determined according to the determination standard GB/T3916-2013 of the breaking strength and the breaking elongation of single yarn of the textile.
As shown in table 1, the CIE Lab values of the fabrics dyed with different concentrations of the carrier and different dyes in the fabrics varied, and as in examples 1 and 2, the cationic red X-GRL was used to dye the polyimide fabric, the a value of the dyed fabric increased significantly, the b value decreased, indicating that the fabric color shifted away from yellow and closer to red, and the decrease in the L value indicated that the dye dyed the fabric to darken. Comparison of the color parameters of the other examples, comparative examples and polyimide fabrics shows that the dye uptake is greatly improved with the aid of the carrier. The color fastness to washing of the dyed fabric is above grade 3, and the strength is well maintained. The example 1 and the comparative examples 1, 2 and 3 are respectively a ketone ester carrier, a carrier-free carrier, an amide carrier and an ether alcohol carrier, and it can be seen that after the fabric is dyed by the cationic red X-GRL, the a value of the fabric dyed by the ketone ester carrier is the largest, which indicates that the red color shown on the fabric is most obvious, the ether alcohol is the second, the amide effect is poor, which indicates that the ketone ester carrier is dyed, and the dye-uptake condition is better. However, because of the pungent taste, in actual production, the ketoester carrier can be compounded with other carriers with good effect to inhibit the pungent smell and improve the dyeing effect.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
