Embodiment 1

[0030] refer to figure 1 The process flow of the present invention shown is as follows: pattern reading and writing design→ink preparation→fabric pretreatment→digital direct printing:

[0031] 1. Pattern reading and writing design: input the pattern required for printing into the computer and save it.

[0032] 2. Ink preparation: the ink required by the invention is prepared by adding an environmentally friendly self-crosslinking adhesive at 3-5% by weight of the ink.

[0033] 3. Fabric pretreatment: After the gray cloth is boiled, the prepared slurry is used to sizing the gray cloth. The composition of the slurry is as follows:

[0034] Synthetic dragon gum 2~3%

[0035] Sodium alginate 3~5%

[0036] Urea 8~15%

[0037] Baking soda 2~5%

[0038] Yuanming powder 2~5%

[0039] The balance is water

[0040] Put the above components into a beater after mixing, and beat for 1 to 1.5 hours until the slurry is uniform.

[0041] After the sizing process, the blank is pressed ...

Embodiment 2

[0044] Processing step is the same as embodiment 1, and difference is that heat setting pressure is 2.5kgf / cm 2 , The heating temperature is 250°C.

Embodiment 3

[0046] Processing step is the same as embodiment 1, and difference is that heat setting pressure is 3kgf / cm 2 , the heating temperature is 200°C.

Abstract

The invention discloses a natural silk and artificial silk digital printing technique, which belongs to the printing technical field. The technique comprises the following steps: read-write design of patterns, preparation of ink, pretreatment of textile fabrics, digital jet printing and so on. By addition of an environment-friendly self-crosslinking adhesive into the ink and adoption of the special heat-setting technique, the upper part and the lower part of a blank after sizing are tightly pressed and heated by two electric blankets; and the pressure is between 2 and 3kgf/cm<2>, and the heating temperature is between 200 and 280 DEG C. Products prepared by adoption of the technique still can not be faded after water scrubbing for a plurality of times and even under more severe experimental environments and maintain the prior color and the prior brightness.

Description

technical field [0001] The invention relates to a printing process, in particular to a digital printing process for real silk and imitation silk. Background technique [0002] With the development of the printing and dyeing industry, digital printing has been widely promoted and applied. Digital printing is to input the pattern into the computer in digital form, edit and process it through the computer printing color separation scanning system, and then control the inkjet nozzle by the computer to inject the special dye Spray it on the textile to form the desired pattern, which has the advantages of clear image, rich color and high grade. At present, the types of digital printing include cotton, wool, chemical fiber and other types of fabrics, and less fabrics such as silk are involved. This is because, due to the characteristics of silk (including real silk and imitation silk), the surface of the fabric is relatively smooth. Both digital direct printing and digital transfe...
