All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," and the like in the terms of the invention are used for descriptive purposes only and not for purposes of indication or implication relative importance, nor as a limitation on the order of precedence.

The invention provides a pretreatment liquid based on polyester fabric ink jet, which comprises the following components in parts by mass:

wherein the film forming material is one or two of hexafluorobutyl methacrylate and trifluoroethyl methacrylate;

the cationic surfactant is one or two of dipalmitoyl carboxyethyl hydroxyethyl methyl ammonium sulfate and methacryloyloxyethyl trimethyl ammonium chloride;

the solubilizer is one or two of ethylene glycol, diethylene glycol and propylene glycol;

the complexing agent is one or two of hydroxyethylidene diphosphonic acid, disodium hydroxyethylidene diphosphonate and tetrasodium hydroxyethylidene diphosphonate.

The invention also provides an ink-jet treatment method of the polyester fabric, which comprises the following steps:

s1, adding water into the pretreatment solution to dilute the pretreatment solution by 8-30 times;

s2, uniformly spraying the pre-treated diluted solution on the polyester fabric or soaking the polyester fabric in the diluted solution through a sprayer;

s3, taking out the polyester fabric, and drying the polyester fabric at the temperature lower than 80 ℃;

according to the pretreatment liquid based on polyester fabric ink jet, the film forming substance is one or two of hexafluorobutyl methacrylate and trifluoroethyl methacrylate, can be firmly adhered to the surface of polyester fiber, plays an adhesion role between the polyester fabric and textile ink, and can enhance the binding force of the textile ink on the polyester fabric, so that the color fastness is ensured to reach the standard. Meanwhile, due to the blocking effect of the film layer, the diffusion and the blooming of the textile ink on the polyester fiber are avoided. The problems that in the prior art, pigment is scattered and diffused when textile ink is used on polyester fabric, and the color fastness detection is not up to the standard are solved.

Meanwhile, with reference to fig. 1, the following process of the polyester fabric treatment method is explained in detail:

it is to be noted, however, that the following description of various embodiments of the present invention is provided by way of example for purposes of further understanding, and it is to be understood that such description is merely intended to further illustrate features and advantages of the present invention and is not intended to limit the scope of the appended claims.

Example 1:

hexafluorobutyl methacrylate, dipalmitocarboxyethyl hydroxyethyl methyl ammonium methyl sulfate, ethylene glycol, hydroxyethylidene diphosphonic acid and water are mixed according to the mass percentage of 5: 2: 6: 5: and 82, proportional configuration.

In the present embodiment, the water solubility of hexafluorobutyl methacrylate is better than that of trifluoroethyl methacrylate, mainly because six fluorine atoms in the molecule of hexafluorobutyl methacrylate can form hydrogen bonds with hydrogen atoms in water molecules, so that the hexafluorobutyl methacrylate is more soluble in water. Because the content of the film forming material hexafluorobutyl methacrylate is lower and is only 5 percent, and the water solubility of the film forming material is relatively better, the percentage content of the surfactant and the solubilizer can be correspondingly reduced. The content of the complexing agent is 5 percent, so as to complex metal salt ions contained in water and stained on the surface of the fabric.

The embodiment is suitable for preparing a thinner (10-50 nm) coating on the polyester fabric. After treatment, the ink-jet requirements can be basically met, namely, the pigment has no obvious phenomena of blooming and diffusion and the color fastness is above 3-4 grade. Meanwhile, the embodiment is a scheme with the lowest content of film forming substances, cationic surfactants, solubilizing agents and complexing agents in meeting basic ink jet requirements.

Example 2:

performing mass percent of trifluoroethyl methacrylate, methacryloyloxyethyl trimethyl ammonium chloride, diethylene glycol, disodium hydroxyethylidene diphosphonate and water to obtain a mixture, wherein the mass percent of the mixture is 15: 8: 15: 1: and (5) configuring the scale 61.

In this example, the film formation thickness of trifluoroethyl methacrylate was thicker than that of hexafluorobutyl methacrylate, mainly because the molecular chain length of trifluoroethyl methacrylate was shorter and the intermolecular polymerization packing was denser, which made the film formation thickness thereof larger. However, the water solubility of trifluoroethyl methacrylate is relatively poor, and the percentage content of the surfactant and the solubilizer needs to be increased to ensure that the trifluoroethyl methacrylate is completely dissolved in water, so that the percentage content of the complexing agent can be properly reduced to 1%.

The embodiment is suitable for preparing the medium-thickness (50-200 nm) coating on the polyester fabric. After treatment, the quality after ink jetting is good, namely, the pigment basically has no phenomena of blooming and diffusion and has the color fastness of more than 4 grades.

Example 3:

hexafluorobutyl methacrylate, trifluoroethyl methacrylate, bis-palmitoyl carboxyethyl hydroxyethyl methyl ammonium methyl sulfate, propylene glycol, tetra sodium hydroxyethylidene diphosphonate and water in a mass percentage of 7: 18: 10: 18: 0.3: 46.7 ratio configuration.

In the embodiment, the film forming material is a mixture of hexafluorobutyl methacrylate and trifluoroethyl methacrylate, the percentage content of the hexafluorobutyl methacrylate and the trifluoroethyl methacrylate is 25%, and the molecules of the hexafluorobutyl methacrylate and the trifluoroethyl methacrylate are mutually crosslinked and tightly combined, so that the wear resistance and the aging resistance of the coating can be optimized. Moreover, as the percentage content of film-forming substances increases, the thickness of the coating further increases. The two substances are matched with each other, the influence on the water solubility of the two substances is small, and only a proper amount of surfactant and solubilizer are needed. As the percentage content of water in the formula is reduced, the content of the complexing agent is correspondingly reduced.

The embodiment is suitable for preparing thick and solid (200-1000 nm) coatings on polyester fabrics. The polyester fabric after treatment has smooth and exquisite hand feeling, can be sprayed with ink to draw complex patterns, and has excellent quality, namely, the pigment has no phenomena of blooming and diffusion completely, and the color fastness is grade 5.

By combining the above embodiment, the invention can realize good ink jet of the textile ink on the polyester fabric: the phenomena of pigment blooming and pigment diffusion are avoided, and the color fastness reaches the standard. Meanwhile, the softness and comfort of the polyester fabric are not changed.

According to the pretreatment liquid based on polyester fabric ink jet, the film forming substance is one or two of hexafluorobutyl methacrylate and trifluoroethyl methacrylate, can be firmly adhered to the surface of polyester fiber, plays an adhesion role between the polyester fabric and textile ink, and can enhance the binding force of the textile ink on the polyester fabric, so that the color fastness is ensured to reach the standard. Meanwhile, due to the blocking effect of the film layer, the diffusion and the blooming of the textile ink on the polyester fiber are avoided. The problems that in the prior art, pigment is scattered and diffused when textile ink is used on polyester fabric, and the color fastness detection is not up to the standard are solved.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
