Embodiment 1

[0026] A pre-printing treatment slurry, which includes the following raw materials in parts by weight: 2 parts of cationic paste EM-108 (purchased from Yimei Chemical Company), 4 parts of cosolvent urea, 0.1 part of pH buffer agent lactic acid, 2 parts of electrolyte Yuanming powder, 1 part thickener fumed silica, 0.2 part retarder 1227, 90.7 parts deionized water.

[0027] Its preparation method includes the following steps: taking materials according to the ratio of raw materials, mixing co-solvent, electrolyte, pH buffer and retarder with deionized water, and then adding thickener and cationic paste under stirring, with cationic paste The viscosity of the system will gradually increase due to the swelling of the material and thickener, and the stirring speed will be increased. Specifically, the stirring speed and time can be adjusted according to the viscosity of the slurry to ensure that the mixture can be stirred evenly and quickly. The total stirring time is 3 to 4 hours,...

Embodiment 2

[0029]A pre-printing paste, which includes the following raw materials in parts by weight: 2.5 parts of cationic paste, 4 parts of cosolvent urea, 0.1 part of pH buffering agent acetic acid, 4 parts of electrolyte sodium sulfate, 1 part of thickener gas phase two Silicon oxide, 0.1 part of retarder 1227, 88.3 parts of deionized water. Its preparation method is basically the same as that of Example 1; the pH value of the prepared pre-printing slurry is 4.5, and the viscosity is 2000 mPa·s. Store the prepared printing pretreatment slurry at a low temperature of 10°C for future use.

Embodiment 3

[0031] A printing pretreatment slurry, which includes the following raw materials in parts by weight: 3 parts of cationic paste, 6 parts of cosolvent urea, 2 parts of pH buffer ammonium sulfate, 0.1 part of pH buffer citric acid, 2 parts of electrolyte Yuan Ming Powder, 1 part thickener fumed silica, 0.1 part retarder 1227, 85.8 parts deionized water. Its preparation method is basically the same as that of Example 1; the pH value of the prepared pre-printing slurry is 5.8, and the viscosity is 2200 mPa·s. Store the prepared printing pretreatment slurry at a low temperature of 10°C for future use.

[0032] The pre-printing treatment paste prepared above can be applied to the pre-treatment of acrylic fabric cationic dye ink inkjet printing, and then to carry out printing and dyeing of nylon fabric. Thus, the invention provides a kind of acrylic fabric ink-jet printing technique, comprises the following steps:

[0033] S1, using the pre-printing slurry obtained above to sizing ...

Abstract

The invention discloses a printing preprocessing sizing agent and a preparation method thereof, and a jet ink printing technology for an acrylic fibre fabric. The printing preprocessing sizing agent comprises the following raw materials in parts by weight of 1-5 parts of a cation thickener, 3-12 parts of a solubilizer, 2-4 parts of a pH buffer agent, 0-4 parts of electrolyte, 0-2 parts of a thickening agent and 0.2-2 parts of a retarding agent. The preprocessing sizing agent is used for preprocessing for jet ink printing of cationic dye ink for the acrylic fibre fabric, and further patterns obtained by jet ink printing are clear in outline, bright in color, good in color fastness and simple in dying steps.

Description

technical field [0001] The invention relates to textile printing and dyeing, in particular to a pre-printing treatment paste, a preparation method thereof and an ink-jet printing process for acrylic fabrics. Background technique [0002] Cationic dye is a kind of cationic dye, which is water-soluble, and is mainly used for dyeing acrylic fiber. During the polymerization process of acrylic fiber, a third monomer is introduced to make the fiber molecule contain a certain number of negatively charged groups, which can be combined with cationic dyes during dyeing. The positive charges of the dyes are ionically bonded. Acrylic fibers are dyed with cationic dyes, and they are almost not dyed below the glass transition temperature. When the glass transition temperature exceeds the glass transition temperature, the dyeing rate increases sharply, and it is very easy to dye flowers. Therefore, in the traditional dyeing bath, the amount of dye needs to be controlled, the heating and c...
