Because of different physical and chemical properties of terylene and cotton fibers, the terylene is dyed by using disperse dye and the dyeing temperature is high, and the cotton fibers are dyed by using reactive dye and the dyeing temperature is low, the terylene-cotton blended fabric mainly adopts a two-bath method and a one-bath two-step method, and the dyeing processes generally adopt water as a dyeing medium, so that the main problems are that the dyeing time is more, the production efficiency is low, the consumption of water, electricity, steam and the like is larger, a large amount of high COD wastewater can be generated, and the environment is not friendly.
At present, aiming at the problem of large water consumption in dyeing, technicians develop water-saving dyeing and nonaqueous medium dyeing technologies, wherein the nonaqueous medium dyeing technologies adopt a supercritical carbon dioxide system, a reverse micelle system and an organic solvent suspension system for dyeing, and can obtain better water-saving and emission-reducing effects.

The reactive dye has more polar groups in the molecular structure and larger molecular volume, is easy to form Van der Waals force combination with polyester fibers, and sodium dodecyl sulfate and halogenated indenone in the anti-staining agent can generate adsorption competition with the reactive dye, so that the staining of the reactive dye to the polyester fibers is greatly reduced through shielding and steric hindrance effects.
In addition, the permeability of disperse dye is stronger, the disperse dye is easy to form a hydrogen bond with carbonyl on cotton fiber, molecular adsorption is formed on the surface of cotton fiber through sodium dodecyl sulfate and halogenated indenone, thiodiglycol is embedded into an adsorption layer to form a continuous phase interface layer, so that the disperse dye can be restrained from permeating into the cotton fiber, meanwhile, the contact area between the disperse dye with a linear molecular structure and the surface of the cotton fiber is reduced, the staining condition of the disperse dye on the cotton fiber is reduced, the mutual staining condition of polyester-cotton blended fabrics is greatly reduced through the comprehensive effect of the staining inhibitor, the fabric has higher dye uptake and level-dyeing rate, and the staining rate is low.

By adopting the technical scheme, the temperature is raised to 80 ℃ at a relatively high temperature rising speed, so that the diffusion of disperse dye molecules is promoted, and the occurrence of the anti-agglomeration phenomenon is reduced. Then the temperature is raised to 120-160 ℃ at a slower temperature rising speed, so that disperse dye molecules are rapidly diffused into the fibers, the concentration polarization phenomenon is reduced, the molecular chain movement of a crystallization area and an amorphous area in the polyester fibers can be accelerated, the speed of accepting the disperse dye molecules by the polyester fibers is increased, and the dye uptake and the fixation rate are improved.
Preferably, in the step S3, the washing is performed by washing with an organic solvent at a temperature of 70-90 ℃ for 20-30min, and then washing with water at a temperature of 85-90 ℃ for 15-20min.
By adopting the technical scheme, the organic solvent is used for cleaning at the temperature of 70-90 ℃, so that the floating color on the surface and in the gaps inside the polyester-cotton blend fiber can be removed, and the subsequent water consumption is reduced. The fabric is cleaned at a higher temperature by using water, so that dye molecules attached to the surface of the fiber can be further removed, and the generation of color spots on the fabric is reduced.
Preferably, the organic solvent is one of decamethyl cyclopentasiloxane, dimethyl sulfoxide, ethanol, xylene, ethyl acetate and dimethyl carbonate.
Preferably, the organic solvent is decamethyl cyclopentasiloxane.

Performance test
Detection method
The polyester-cotton blend fabrics obtained in examples 1 to 12 and comparative examples 1 to 5 were tested for the dyeing degree of the disperse dye on cotton fibers and the dyeing degree of the reactive dye on polyester, wherein the dyeing degree of the disperse dye on cotton fibers is the percentage of the dye on the cotton fibers, which is dyed by the disperse dye, to the total disperse dye, and the dyeing degree of the reactive dye on the polyester is the percentage of the dye on the polyester, which is dyed by the reactive dye, to the total reactive dye, and the test results are shown in table 1.
Table 1 test data for the dyeing degree of the low water dyeing process of the polyester-cotton blend fabrics of examples 1 to 12 and comparative examples 1 to 5
As can be seen from the analysis of examples 1 to 3 and comparative example 1 in combination with Table 1, the use of decamethyl cyclopentasiloxane as a non-aqueous dyeing medium, while adding disperse dye and reactive dye for one-bath one-step dyeing, can greatly reduce water consumption. And the anti-staining agent is added, so that the reactive dye plays a role in competing and staining, the staining rate of the reactive dye on polyester is reduced, and on the other hand, the sodium dodecyl sulfate and the halogenated indenone form molecular adsorption on the surface of cotton fiber, and form a continuous phase interface layer under the assistance of thiodiglycol, so that the staining of the disperse dye on the cotton fiber is inhibited, and the mutual staining rate of polyester cotton components in the staining process is reduced on the whole. It can be seen that the dyeing rate of the disperse dye to the cotton fiber is reduced by about 66% and the dyeing rate of the reactive dye to the polyester is reduced by about 47.4% in example 3 compared with comparative example 1 in which the dyeing inhibitor is not added. Moreover, as can be seen from analysis examples 1-3, the contamination rate of the reactive dye on the polyester has a certain relation with the content of sodium carbonate, and the sodium carbonate can promote the hydrolysis of the reactive dye attached to the surface of the polyester, so that the contamination rate of the reactive dye in the polyester component is reduced.
As can be seen from the analysis of examples 1 to 3 and comparative examples 2 to 5 in combination with Table 1, sodium dodecyl sulfate alone was not able to form a continuous phase interface layer on the surface of cotton fibers, and it was not possible to well inhibit the contamination of cotton fibers with disperse dyes. The sodium dodecyl sulfate and the thiodiglycol are compounded and used, and the sodium dodecyl sulfate and the 4-chloroindenone are compounded and used, so that the disperse dye cannot be well inhibited, and the continuous phase interface layer structure formed is possibly imperfect.
As can be seen from the analysis of examples 4 to 5 and examples 6 to 8 in combination with table 1, the composition and the proportion of the anti-staining agent are optimized and adjusted, and the substituent of the halogenated indenone is screened at the same time, so that the mutual staining amount of the disperse dye and the reactive dye on the polyester cotton component is further reduced.
As can be seen from the analysis of examples 9-10 and examples 11-12 in combination with table 1, optimizing and adjusting the cleaning process can remove the flooding and unbound fast dye on the polyester-cotton blended fabric and improve the leveling property of the fabric. And after the hydroxyethylidene diphosphonic acid is added, the structural stability of the continuous phase interface layer can be enhanced, the pollution effect of the disperse dye on cotton fibers can be further inhibited, and the dyeing speed and the dyeing effect of the reactive dye on the cotton fibers can be improved.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
