Description

Red dye composition for dyeing and printing
Technical Field
The invention relates to a dye composition, in particular to a red dye composition for dyeing and printing and application thereof in textile dyeing and printing.
Background
Disperse dyes generally do not contain hydrophilic groups and belong to nonionic dyes. Disperse dyes obtained by synthesis cannot generally be used directly for dye, printing applications and require commercial processing of the dyes to form dispersions of suitable particle size or powdered products readily dispersible in water. In the commercialized processing process, in order to enable the hydrophobic disperse dye to be sufficiently wetted and dispersed and have proper printing and dyeing application performance, a large amount of water-soluble anionic or nonionic auxiliary agents are generally required to be added, and the use amount of the auxiliary agents in the commercial disperse dye is generally larger than that of the dye by weight. These auxiliaries generally do not dye fibers, and can enter into dye baths or washing water in the application process of printing and dyeing, and become a main source of COD of the printing and dyeing wastewater.
The energy saving and emission reduction is a main direction of technology upgrading in the printing and dyeing industry all the time, the consumption of an auxiliary agent in disperse dyes is reduced, the COD of printing and dyeing wastewater can be reduced from the root, the method is an important direction of energy saving and emission reduction of the disperse dyes in recent years, chinese patent No. CN105970671A, a dyeing and coating integrated dyeing and printing slurry composition, CN106049091A, a dyeing and coating integrated dyeing and printing dye slurry composition, CN106087464A, a dyeing and printing process and the adopted dyeing and coating integrated technology are used as a novel energy saving and emission reduction technology, the consumption of the auxiliary agent in the conventional disperse dyes is reduced by 50-70%, a certain amount of anionic and nonionic auxiliary agents are still used, and the higher COD in the printing and dyeing wastewater can be brought.
Chinese patent ZL96115131.5 discloses a kind of water-temporary soluble disperse dye, wherein carboxymethyl sulfonyl is introduced into a hydrophobic disperse dye matrix, so that the disperse dye has the property of being soluble in water, and conventional disperse dye auxiliary agents are not required to be added in the processing and application processes. Under the high temperature condition of dye dyeing, the water-soluble dye undergoes decarboxylation reaction to release CO2 gas, and is converted into nonpolar disperse dye to dye the fiber or textile. The dye can be processed and used without adding auxiliary agents, but is limited by different dye parent structures, the decarboxylation reaction temperature and reaction speed of the carboxymethyl sulfonyl are different, the synchronous dyeing of the blended dye is greatly influenced, and meanwhile, the relative manufacturing cost is higher than that of the traditional commercial disperse dye and is not commonly adopted by the industry to date.
Chinese patent CN111019393a discloses a liquid composition containing a disperse dye for yellow dyeing and printing. The dye composition has hydrophilic and hydrophobic dye monomers, does not contain a dispersing agent commonly used in commonly dispersed dyes, has better fastness performance, does not need a complex water washing process, does not generate high COD and high chromaticity sewage, and is a cleaner dispersed dye product. However, the technical scheme is limited to a part of yellow disperse dye varieties, and the polarity of conjugated groups and the structure of dye among the disperse dye varieties with different colors are greatly different, and the dye adopting the patent structure is not suitable for other varieties except yellow, while the diazo component or the coupling component of the azo dye introduces carboxymethyl sulfonyl at different substitution positions, the reflection wavelength of the dye cannot be greatly influenced. This causes the disadvantage of incomplete chromatography of the technology of this patent, which is disadvantageous for full-color applications,

as can be seen from the above examples and comparative examples, the fastness properties of the dye obtained after dyeing are similar to those of the main body conventional disperse dye, but since the hydrophilic dye adopted in comparative example 1 has ionic groups, the hydrophilic dye is partially adsorbed on the surface of the hydrophobic dye, which is helpful for improving the hydrophilicity of hydrophobic red-1 (C.I. disperse red 167), but the overall dispersing ability is weaker, the viscosity is higher in the processing process, and the particle size of the dye is many times larger than that of the final liquid dye product obtained in example 1 under the same grinding time condition.
The hydrophilic dye adopted in the comparison 1 has ionic groups, but can not be converted into hydrophobic groups in the use process, has no property of hydrophilic before hydrophobic, has no affinity with hydrophobic fibers, has larger influence on fastness in the whole dye application process, and is not suitable for being used as a dye for hydrophobic printing and dyeing application.
It can be seen from the comparative examples that not all red hydrophilic dyes except the hydrophilic red dye component described in the patent claims are suitable for use in a similar application to the present patent.
The liquid disperse dye composition prepared in each example in examples 1-15 has excellent fastness performance after dyeing and printing application, is more than grade 4, and is suitable for printing and dyeing application of hydrophobic fabric with high fastness requirements.
