Problems solved by technology

However, when general film-forming substances are added to inkjet printing ink, the problems that are likely to occur are: (1) causing the aggregation of ultra-fine pigment particles in the ink, resulting in flocculation and precipitation; After being applied to the fabric, a dense, continuous and smooth printing film cannot be formed on the surface of the fabric; (3) The printing film is easily damaged when it is rubbed in a wet environment, causing the pigment particles to fall off
[0006] However, the use of cross-linking agents in ultra-fine pigment inks to carry out digital inkjet printing of textiles, and the method of improving color fastness by improving the quality of cross-linked films has not been reported yet.

Embodiment 1

[0022] 1. Preparation of inkjet printing pigment ink:

[0023] Take 25g of pigment red paste, 10g of diethylene glycol, 5g of glycerol, 20g of adhesive HY-FB, 10g of water-based polyurethane, 5g of citric acid, 0.3g of OP-10, and 24.7g of deionized water. Put the above components into the container in turn, mix evenly, stir with a mixer at 450 rpm for 10 minutes, filter (0.5 μm microporous membrane) to make superfine pigment red ink;

[0024] 2. Inkjet printing:

[0025] Use the inkjet printing machine to print the superfine pigment red ink on the pure cotton woven calico, dry it in the oven under the condition of temperature: 80°C, time: 3 minutes, and then at the temperature: 150°C , the time is: bake and fix the color under the condition of 3 minutes. Obtain sample A, and test the color fastness of the fabric using a rubbing fastness meter and a color measuring and matching instrument. The results are shown in Table 1.

Embodiment 2

[0027] 1. Preparation of inkjet printing pigment ink:

[0028] Get pigment yellow paste 15g, diethylene glycol 15g, polyethylene glycol 200 10g, 1,4-butanediol 10g, glycerol 5g, binder FWT (BASF company) 10g, crosslinking agent EH 5g , butane tetracarboxylic acid 10g, Pingpingjia 0 0.5g, Tween 80 0.5g, deionized water 19g. Put the above components into the container in turn, mix evenly, stir with a mixer at 500 rpm for 15 minutes, filter (0.5 μm microporous membrane) to make superfine pigment yellow ink;

[0029] 2. Inkjet printing:

[0030] Use the inkjet printing machine to print the superfine pigment yellow ink on the pure cotton woven calico, dry it in the oven under the condition of temperature: 90°C, time: 2 minutes, and then at the temperature: 140°C , the time is baked and fixed under the condition of 4 minutes. Obtain sample B, and test the color fastness of the fabric by using a rubbing fastness meter and a color measuring and matching instrument. The results are...

Embodiment 3

[0032] 1. Preparation of inkjet printing pigment ink:

[0033] Get 15g of pigment blue paste, 1,4-butanediol 10g, glycerol 15g, binder HY-FB (Qingdao Haiyi Company) 20g, butane tetracarboxylic acid 10g, Tween 60 0.5g, deionized Water 29.5g. Put the above components into the container in turn, mix evenly, stir with a mixer at 550 rpm for 12 minutes, filter (0.5 μm microporous membrane) to make ultrafine pigment blue ink;

[0034] 2. Inkjet printing:

[0035] Use the inkjet printing machine to print the ultra-fine pigment blue ink on the pure cotton woven calico, dry it in the oven at a temperature of 85°C and a time of 4 minutes, and then dry it at a temperature of 135°C , the time is baked and fixed under the condition of 3.5 minutes. Obtain sample C, and test the color fastness of the fabric by using a rubbing fastness meter and a color measuring and matching instrument. The results are shown in Table 1.

Abstract

The invention relates to a method used to increase inking printing dye ink color fastness. It includes the following steps: orderly adding dye color paste, polyhydric alcohol, adhesive, cross linking agent, surface activator in proportion into container; adding water to mix evenly; stirring, filtrating to form super fine dye ink; jet printing on the fabric; drying, baking to fix. The printing film formed by cross linking agent makes the super fine dye particle can tolerate dry wet friction, can increase its color fastness on the fabric without influencing on ink injecting performance.

Description

technical field [0001] The invention relates to a method for improving the color fastness of ink-jet printing pigment ink, which belongs to the technical field of textile printing and dyeing. Background technique [0002] With the development and popularization of digital technology, textile digital inkjet printing technology has become the most promising ecological textile technology in the 21st century, among which the research and development of ultrafine pigment ink for digital inkjet printing is the key to solving digital inkjet printing technology one of the links. However, due to the addition of a large amount of polyols in the ink preparation process. After spray printing onto the surface of the fabric, the hydrophilicity of the polyol can easily cause the swelling of the printing film in a wet environment, resulting in a decrease in the wet rubbing fastness of the superfine pigment attached to the fabric. [0003] In order to solve the problem of low wet rubbing f...
