Problems solved by technology

However, the current digital printing and printing technology only prints on the surface of the fabric, similar to the "paint" treatment method. On the one hand, it is not suitable for traditional inks. On the other hand, the color fixation of textile printing and dyeing is not enough. The printed fabric is less comfortable to wear

Embodiment 1

[0056] A non-steaming, non-washing inkjet ink and a printing and dyeing method, wherein the components of the printing and dyeing ink are: dye 5-10%, ethylene glycol 8-10%, diethylene glycol 8-10%, glycerin 5% by weight ~6%, anti-staining salt K 0.1~1%, sodium carbonate 0.1~0.5%, sodium sulfate 0.1~2%, urea 0.1~1%, sodium bicarbonate 0.1~3%, sodium hexametaphosphate 0.1~1%, The balance is deionized water.

[0057] The inkjet ink modifier is composed of triethylenediamine, tripropyldiamine, N,N-dimethylhydrazine, N-methylcyclobutylamine and polyethyleneimine, and its mass ratio is 1:1:1: 1:1 with a pH of 9.

[0058] Taking denim as an example, the specific printing and dyeing process is as follows:

[0059] S1. Before the denim fabric is printed and dyed, the aqueous solution of the inkjet ink modifier is soaked and treated to form a modified layer on the surface of the fabric. After the treatment, the denim fabric has a liquid content of 50% and is dried;

[0060] S2. Then ...

Embodiment 2

[0066] A non-steaming, non-washing inkjet ink and printing and dyeing method, wherein the printing and dyeing ink is the same as that of Embodiment 1, and the specific printing and dyeing process is the same as that of Embodiment 1. The sexual agent is composed of tripropyldiamine, N,N-dimethylhydrazine, N-methylcyclobutylamine and polyethyleneimine, and its mass ratio is 1:1:1:1, and its pH is 9.

[0067] The denim fabric after printing and dyeing, then the effect is good, the color is saturated, the color does not fade after washing, and the color is fast.

Embodiment 3

[0069] A non-steaming, non-washing inkjet ink and a printing and dyeing method, wherein the components of the printing and dyeing ink are: dye 5-10%, ethylene glycol 8-10%, diethylene glycol 8-10%, glycerin 5% by weight ~6%, anti-staining salt K 0.1~1%, sodium carbonate 0.1~0.5%, sodium sulfate 0.1~2%, urea 0.1~1%, sodium bicarbonate 0.1~3%, sodium hexametaphosphate 0.1~1%, Deionized water balance.

[0070] The inkjet ink modifier is composed of triethylenediamine, tripropyldiamine, N,N-dimethylhydrazine, N-methylcyclobutylamine and polyethyleneimine, and its mass ratio is 0.5:0.5:0.5: 0.5:1 with a pH of 8.

[0071] Taking knitted fabric as an example, the specific printing and dyeing process is as follows:

[0072] S1. Before printing and dyeing, the knitted fabric is soaked with the aqueous solution of the above-mentioned inkjet ink modifier, and a modified layer is formed on the surface of the fabric. After the treatment, the knitted fabric has a liquid content of 50% and...

Abstract

The invention discloses a simple and convenient digital direct-injection printing and dyeing method free of steaming and washing. It includes the following steps: S11. Fabric pretreatment; S12. Digital inkjet printing and dyeing; S13. After the cloth inkjet printing is completed, drying is the printing and dyeing cloth; or, it includes the following steps: S21. Digital inkjet printing and dyeing; , fix the color of the fabric modifier aqueous solution; S23. After the fabric fixation is completed, drying is to print and dye the fabric; the modifier can increase the number of hydroxyl groups in the fabric fibers, and make the hydroxyl groups in the fabric fibers and the fabric fibers. A more stable substance to which the reactive groups in the dye bind. The method of the invention saves the steaming and water washing processes in the traditional process, reduces the treatment and discharge of a large amount of sewage, and completely reaches the standard of zero discharge, which is not only environmentally friendly, but also greatly saves energy consumption and reduces At the same time, the printed and dyed fabrics are fast in color, not easy to fade, and the color is saturated, and the dyeing effect has reached the international export standard.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, and more particularly, to a simple and convenient digital direct-injection printing and dyeing method that is free of steaming and washing. Background technique [0002] Traditional digital printing is to use digital technology to print various textiles. The processing process is to input the image into the computer through various digital digital means, and then edit and process it through the printing software system to form the required pattern, which is then controlled by the input software. The inkjet printer directly prints various special inks on the sizing fabric, and then undergoes steam at 102°C, color fixing, water de-sizing and de-floating, and then fixing and shaping, and then the finished product is obtained. Green cloth sizing-setting-digital printing-drying-steam fixing-washing-setting-finished product. [0003] In the above process, due to the limitations of the dye ...
