Problems solved by technology

Among them, the color paste is mainly composed of sodium alginate and other components, and nearly 30% of the color paste will enter the sewage from printing to washing the finished product. Printing and dyeing wastewater, sewage treatment is cumbersome, and post-treatment costs are high
At the same time, since the color paste contains a large amount of alkaline components such as urea and ammonia water, multiple washings are required to meet the safety requirements of the finished fabric. Steaming also requires a large amount of heat and electricity, and the consumption of water and heat sources is relatively high. In addition, the particle size of the color paste is basically at the micron level, and there is no finer color paste report in the existing reports. In the printing process, the color paste only stays on the surface of the fiber or fabric, and the fineness of the printing pattern and accuracy, as well as limited stereoscopic effect and aesthetics

Embodiment 1

[0024] In this embodiment, the nanometer 3D printing process combines figure 1 , including the following steps:

[0025] (1) Gray cloth finishing: Clean the gray cloth to remove obvious stains, and set it aside.

[0026] (2) Ink preparation: The ink is composed of dyes, dispersing additives and water.

[0027] The nano-ink formed by the above preparation is placed in the ink cartridge of the printing machine in the printing section 3 for use.

[0028] (3) Send the gray cloth of step (1) into the discharge part 1, and under the influence of each traction roller of the discharge traction part 2, the gray cloth is sent to the printing part 3. In the printing part 3, the number of screen lines is 55-175LPI , the speed of the printing machine is 80-200m / min, the printing temperature is 180-230°C, and the pressure is 1-2um. The nano-holes (inking holes) on the anilox roller 31 transfer the ink quantitatively to the passing gray cloth. After the transfer is completed, send it to T...

Embodiment 2

[0030] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that the printing process is different, and the parameters of the printing process are compared as shown in Table 1.

Abstract

The invention relates to a nanometer 3D (three-dimensional) printing process, and belongs to the technical field of dyeing or printing of fiber or textile. The 3D nanometer printing is realized through nanometer ink by combing a 3D nanometer printing machine. The nanometer 3D printing process is applied to printing of fabrics such as grey cloth and textiles, and has the advantages that the 3D effect is obvious; the energy is saved; the environment is protected; no pollution exists, and the like.

Description

technical field [0001] The application relates to a nanometer 3D printing process, which belongs to the technical field of dyeing or printing of fibers or textiles. Background technique [0002] Textile printing is widely used in daily life and daily work, such as color paste printing, digital inkjet printing, etc. With the improvement of people's requirements for fabric appearance, environmental protection, and safety, 3D printed textiles are characterized by their bright colors. , flower-shaped three-dimensional characteristics, and gradually entered people's lives. Common 3D printing adopts the combination of digital, flat screen and rotary screen, and its process can be described as: gray cloth→color paste preparation→flat screen / rotary screen→printing→setting→air steaming→water washing. Among them, the color paste is mainly composed of sodium alginate and other components, and nearly 30% of the color paste will enter the sewage from printing to washing the finished pro...
