Problems solved by technology

[0003] Most of the current reactive dye resist printing processes use printing screen printing, which mainly has the following three shortcomings: first, the outline of the pattern part of the printing screen resist printing is not clear, easy to bleed, and affects the effect of printing; One is that the ground color is easy to be contaminated during the printing process, causing the ground color to be stained and making the fabric unclean; the third is that the printing process is time-consuming and laborious, it is not easy to control and the amount is large, resulting in a large waste of dyeing and chemical materials
[0004] At present, the amount of dyes dyed on fabrics by inkjet printing technology is small, and the color fixation rate of reactive dyes on cotton fabrics is not high. Therefore, cotton fabrics are currently printed with reactive dye inks, and the color is generally not deep; Due to the smooth fiber surface and poor water holding capacity, when printing with reactive dye ink, it is easy to produce bleeding phenomenon, which reduces the clarity and color depth of inkjet printing patterns.
Although many patents disclose the report of reactive dye inkjet printing process, there is no relevant report on the use of inkjet printing technology to carry out anti-dyeing process
In addition, there is currently no method for double-sided anti-staining

Embodiment 1

[0024] A reactive dye resist printing process based on inkjet printing technology, comprising the following steps: sizing → drying → computer printing color separation and drawing (CAD) editing processing → adjusting anti-dye ink and spray printing → dyeing ground color → steaming → washing drying.

[0025] (1) Sizing treatment: the prescription of sizing agent is: 30% sodium alginate paste, 30% hydroxypropyl guar gum, 5% dispersant, 5% anti-swimming agent.

[0026] (2) Drying: Dry the sizing-treated fabric at 80° C. to 60% dry.

[0027] (3) Computer printing color separation and drawing (CAD) editing processing: through drawing and editing processing, the desired pattern is obtained, and then the inkjet nozzle is controlled by the computer.

[0028] (4) Optimizing the preparation of anti-dyeing reactive blue ink and printing formula: reactive dye 10%, triethylene glycol 6%, 1,4-butanediol 12%, N,N-dimethylformamide 6%, fatty alcohol 8% polyoxyethylene ether; 6% urea, 1% sod...

Abstract

The invention discloses a reactive dye resist printing process based on an ink jet printing technology, and belongs to the technical field of ink jet printing. The reactive dye resist printing process comprises the following steps: starching, drying, computer printing color separation and painting (CAD) editing and processing, preparation of dye resistant and white resistant ink, jet printing, ground dyeing, steaming, washing and drying. The reactive dye resist printing process has the advantages that the process is simple to operate, dye resistant designs can adopt the computer printing color separation and painting (CAD) editing and processing, to obtain required patterns, then the patterns can be printed through an ink nozzle controlled through a computer, the printed designs are clear in outlines and vivid and gorgeous in colors, and meanwhile the dosage and cost can be reduced.

Description

technical field [0001] The invention relates to a reactive dye resist printing process based on inkjet printing technology, belonging to the technical field of inkjet printing. Background technique [0002] Inkjet printing, also known as digital printing, is to print digital patterns on textiles through a textile-specific inkjet printer. This special inkjet printing machine is called a digital printing machine. With the continuous growth of the economic level and the gradual improvement of material living standards, people's requirements for textiles are also increasing. As a brand-new printing technology, digital inkjet printing technology has developed rapidly in recent years. It abandons the complicated plate-making of traditional printing. The printing process has the characteristics of fast, flexible, and fine. Compared with traditional printing, the printing process saves dyeing materials and water resources, and can meet the needs of today's textile market for small b...
