Embodiment 1

[0039] Add 8.0g of melamine, 15.0mL of 38wt% formaldehyde aqueous solution, and 10mL of deionized water into a 250mL three-necked flask in sequence, and adjust the pH of the system to 8.5 with triethanolamine, and stir in a 70°C water bath at a speed of 100rpm until the melamine is completely dissolved. Form a transparent liquid, and finally add 8.0ml of distilled water for reaction to obtain a melamine resin prepolymer solution;

[0040] Add 8.0g TA and 100.0mL deionized water to a constant temperature emulsification kettle at 60°C, heat and melt 16.0g n-octadecane and add it to the constant temperature emulsification kettle. After emulsifying at 5000rpm for 30min, adjust the pH value of the emulsion with 8wt% citric acid to about 4.5 to obtain n-octadecane emulsion;

[0041] Add C.I. Disperse Orange 25 with a particle size of 0.3 μm to the melamine resin prepolymer solution, and then add it dropwise at a rate of 0.3ml / min to n-octadecane emulsion at a temperature of 50°C, and ...

Embodiment 2

[0043] Get the following raw materials by weight: 20 parts of orange-based microcapsule pigments prepared by the above-mentioned embodiment 1, 20 parts of water-based resins, 5 parts of quick-drying solvents, 5 parts of moisturizing solvents, 1 part of surfactants, and the balance plus Deionized water;

[0044] After the above raw material components are mixed, they are fully stirred evenly, and filtered through a filter screen of 1 μm level to remove impurities and bacteria, and the finished ink can be obtained.

Embodiment 3

[0046] The preparation method of orange microcapsule pigment is the same as Example 1, except that the pigment is C.I. Disperse Orange 37;

[0047] The preparation method of the ink is the same as that in Example 2, except that the weight part of the orange microcapsule pigment is 40 parts, and the weight part of the water-based resin is 10 parts.

Abstract

The invention provides orange ink for digital printing of a textile, which belongs to the field of textile pigments, and can solve the problems of hard hand feeling, dull color, low color fastness, unrepresentable brightness and serious service dyeing of a printed textile obtained from existing pigment ink.The orange ink for digital textile printing provided by the technical scheme is prepared from the following materials in parts by weight: 20- 40 parts of orange microcapsule pigment, 10- 20 parts of water-base resin, 5- 15 parts of quick-drying solvent, 5- 15 parts of moisture preserving solvent, and 0.5- 1 part of a surfactant.A microcapsule technology is applied to preparation of the pigment ink for digital printing of the textile, and the printed textile obtained therefrom has the advantages of high color fastness, high textile comfort, safety, and bright color; when the ink is used as textile printing ink, no surface dyeing occurs, and a reduction cleaning process can be omitted,thus reducing environmental pollution and lowering production cost.

Description

technical field [0001] The invention belongs to the field of textile pigments, in particular to an orange-based ink for textile digital printing. Background technique [0002] Digital printing refers to various digital patterns input into the computer through various digital means such as: scanning, digital photos, images or computer processing, and then processed by the computer color separation printing processing system, and then processed by the special RIP software through the printing system. Various dyes are directly sprayed onto various textiles or other media, and after processing, various high-precision printing products required are obtained on various textile fabrics. Compared with traditional printing technology, digital printing has the characteristics of high quality, good quality, low energy consumption and no pollution. Ink is the key material of digital printing, which determines the quality of digital printing. Therefore, the development of ink is of gre...
