Example Embodiment

[0040] Example 1

[0041] A thermal transfer digital printing method for natural fibers and regenerated cellulose fibers, which is carried out according to the following steps:

[0042] (1) Preparation of coating glue:

[0043] Prepare materials by weight percentage of 7% seaweed gum, 1.5% defoamer and 91.5% water. Pour the water into the blender, then slowly pour in the alginate. The blender speed is 600 rpm and stir for 5 minutes. When the defoamer is added, adjust the speed to 1600 rpm and stir for 25 minutes. The viscosity is adjusted to about 3000 cps. , and leave for 2 hours after the preparation is completed.

[0044] (2) Apply printing coating glue

[0045]Coat the prepared coating glue and PET film with a width of 1.6 meters with a coating machine. The coating should be uniform and the thickness should be about 15 μm.

[0046] (3) Film printing

[0047] Put the coated PET film on the digital photo machine, and print the designed pattern with reactive dye ink.

Example Embodiment

[0057] Example 2

[0058] Other operations are the same as in Example 1, except that:

[0059] (5) Top printing paste

[0060] Dip the cashmere scarf to be printed in the printing paste, take it out after it is wet, spin it dry with a dehydrator, the moisture content is 75%, and then put it on the moving plate of the heat transfer printing machine and spread it flat.

[0061] The dye of this embodiment can transfer more than 95%, the printing pattern resolution is high, the pattern layer is clear, and the photo effect is achieved, the floating color is very little during the washing process, the printing color fastness is above 4, and the printing effect is completely imported. Level of digital printing machine.

[0062] Example 3

[0063] Other operations are the same as in Example 1, except that:

[0064] (5) Top printing paste

[0065] Dip the cashmere scarf to be printed in the printing paste, take it out of the paddle after it is wet, and dry it with a moisture content of 75%, and then put it on the moving plate of the heat transfer printing machine and spread it flat.

[0066] The dye of this embodiment can transfer more than 95%, the printing pattern resolution is high, the pattern layer is clear, and the photo effect is achieved, the floating color is very little during the washing process, the printing color fastness is above 4, and the printing effect is completely imported. Level of digital printing machine.

Abstract

The invention relates to a printing method for textiles, in particular to a heat transfer digital printing method for natural fibers and regenerated cellulose fibers. The heat transfer digital printing method comprises the following steps of: spreading and printing a film or a composite film which is subjected to coating treatment and textiles subjected to sizing by using an ironing press at the temperature of between 40 and 100 DEG C for 30 to 90 seconds; stripping the film or the composite film; and drying the textiles subjected to printing, and ageing for color fixing. By the heat transfer digital printing method, the problem that a digital printing machine and a computer photogravure press cannot perform jet printing on the film directly is solved, and the obtained printing textiles have the characteristics of high resolution ratio of printing patterns and distinct gradation of flower types and can achieve a photo effect; and a process is easy to operate and low in production cost.

Description

technical field [0001] The invention relates to a textile printing method, in particular to a thermal transfer digital printing method for natural fiber and regenerated cellulose fiber textiles. 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, bu...
