Problems solved by technology

One of the disadvantages of this printing method is that it uses alkaline dipping solution, which is not suitable for printing protein fibers, and it is easy to cause embrittlement of protein fibers; the other is that it uses high-pressure special equipment and self-made ink, which is complex in process and high in investment.

Embodiment 1

[0037] A method for pattern transfer to fiber fabrics is carried out as follows:

[0038] 1. Paper coating and isolation layer: prepare white kraft paper with a weight of 80g and a width of 1.8m and put it on the laminating machine, heat the solid PE to 140°C, and then pour it on the white kraft paper through the die of the extruder. The coating thickness is 15g / ㎡.

[0039] 2. Preparation of coating glue: Mix the components according to the weight ratio shown in Table 1, and stir with a mixer to form a colloidal coating glue. After the preparation is completed, place it at room temperature for more than 12 hours for later use.

[0040]

[0041] 3. Coating glue for paper coating: use the coating machine to coat the prepared coating glue and the paper with a width of 1.8m and a PE isolation layer on the surface. The coating should be applied on the On the isolation layer, the coating should be uniform. At this time, a transfer layer with a thickness of about 10 μm is formed...

Embodiment 2

[0050] A method for pattern transfer to fiber fabrics is carried out as follows:

[0051] 1. Preparation of coating glue: Mix the components according to the weight ratio shown in Table 1, and stir with a mixer to form a colloidal coating glue. After the preparation is completed, place it at room temperature for more than 12 hours for later use.

[0052] 2. Film coating and printing coating glue: use the coating machine to coat the prepared coating glue and the film with a width of 1.8m. The coating should be uniform. At this time, the surface of the film forms a thickness Transfer layer around 10 μm.

[0053] 3. Printing on the film: put the paper coated with the transfer layer colloid on the digital inkjet printer, and print the designed pattern with reactive dye ink.

[0054] 4. Same as step 5 of embodiment 1, and the wool fabric in embodiment 1 is replaced by cashmere fabric.

[0055] 5. Same as step 6 of embodiment 1.

[0056] 6. Same as Step 7 of Example 1.

[0057]...

Embodiment 3

[0061] A kind of pattern is transferred to the method for fibrous fabric, concrete steps are the same as embodiment 2, difference only lies in the composition of coating glue.

[0062] In this embodiment, the dye transfer rate is over 98%, the pattern resolution is very high, the pattern layers are clear, there is little floating color in the washing process, the color fastness is above grade 4, and the printing effect reaches the level of imported digital printing machines.

Abstract

The invention relates to a printing method of fabrics, and in particular relates to a method for transferring patterns on a fiber fabric. The method comprises the steps of (1) coating a transfer layer: coating a prepared coating adhesive on a film or paper by a photogravure press or a coating machine so as to form the transfer layer on the surface of the film or the paper, drying, and then printing the surface of the transfer layer by utilizing dye base ink to prepare a transfer printing film or transfer printing paper; (2) starching the fiber fabric: coating fixation slurry for transfer printing on the surface of the fiber fabric; (3) transferring the patterns; and (4) evaporating and fixing: after the transfer, stripping the transfer printing film or the transfer printing paper, drying, evaporating and fixing the fiber fabric. According to the method, the difficulties that the dye base ink can not be directly printed on the film, and the transfer rate of the dye on the paper is not high can be solved, and also the transfer layer, the dye, the film and the paper with an isolation layer are not compatible, so that more than 98% of dye can be transferred, and the transfer rate and the color rate of the printing are improved greatly.

Description

technical field [0001] The invention relates to a printing method for textiles, in particular to a method for transferring patterns to fiber fabrics. Background technique [0002] Traditional printing methods will generate a lot of waste water and waste gas, seriously polluting the environment, and the production process requires a lot of steam and heat energy, and energy consumption is increasing day by day. In order to protect the environment and reduce energy consumption, many countries are researching new printing processes that do not use water or use less water, which leads to the sublimation heat transfer printing process. The initial heat transfer printing can only be printed on chemical fiber textiles, and cannot be applied to natural fibers and Regenerated cellulose fiber thermal transfer printing, along with the improvement of the printing process, a method for cold transfer printing on natural fiber fabrics appears, but it is not very ideal. The Chinese inventio...
