Problems solved by technology

[0004] With these solutions, the white ink will still be unstable and the inkjet head will be blocked. The main reason is that the white ink used for heat press transfer paper must be whiter than the white ink for ordinary digital direct printing to cover the dark color, that is to say, the ink Medium white pigment has more content and larger particles, and the inkjet head used for printing transfer paper is often a finer inkjet head, which is difficult to adapt to such white ink

preparation example Construction

[0033] The present invention provides two preparation methods for the preparation of auxiliary color hot-melt adhesive powder, which are respectively a hot-melt preparation method and a mixing preparation method, and the specific steps are as follows:

[0034] Hot-melt preparation method: add auxiliary toner (titanium dioxide, pearl powder or metallic toner) to hot-melt adhesive powder (TPU is the best choice) and stir evenly, heat up and melt and granulate to obtain corresponding hot-melt adhesive particles ( white, pearlescent or metallic color), and then pulverize the hot melt adhesive particles in a refrigerated pulverizer to obtain 60-200 mesh auxiliary color hot melt adhesive powder (white hot melt adhesive powder, pearlescent hot melt adhesive powder or metallic color hot melt powder).

[0035] Mixing preparation method: put auxiliary color powder (titanium dioxide, pearl powder or metallic toner) and hot melt adhesive powder in a powder mixer and fully mix and stir to ...

Embodiment

[0045] 1. The composition and weight percentage of light white paint ink are shown in the following table:

[0046] ingredient name Product name Specification or ratio weight percentage white pigment dispersion white dispersion NK-WNE05 15％ Water-based hot melt adhesive resin Self-dispersing waterborne polyurethane W6110 5％ water-based resin Vinyl resin VINYBLAN 5％ moisturizer Ethylene glycol and glycerol 3:1 20％ Surfactant Suryfnol 465: BYK 2:1 1.5％ fungicide Azoline fungicides BIT 0.5％ Deionized water 43％

[0047] The preparation method of light white paint ink comprises the following steps:

[0048] Step 1. First add deionized water and moisturizing agent into the dispersion tank and stir evenly to obtain the first mixed solution;

[0049] Step 2, adding the surfactant and the bactericide into the first mixed solution and stirring evenly to obtain the second mixed solution;

Abstract

The invention discloses a method for improving ink jet stability and pyrograph color effect by changing hot melt adhesive powder. Pyrograph paper is included, the pyrograph paper comprises transfer paper, a color image-text printing layer, a coating ink layer and a hot melt adhesive powder layer which are arranged in sequence, and the hot melt adhesive powder layer is in contact with a clothing fabric during thermal transfer. The coating ink layer is obtained through ink-jet printing of light white coating ink or transparent coating ink, the hot melt adhesive powder layer is obtained through auxiliary color hot melt adhesive powder, and the auxiliary color hot melt adhesive powder comprises white hot melt adhesive powder, pearlescent color hot melt adhesive powder and metallic color hot melt adhesive powder. The white hot melt adhesive powder and the light white coating ink improve the stability of ink-jet printing and prolong the service life of an ink-jet head, the ink-jet printing ink has the capacity of covering the color of a dark fabric, and the pearlescent color hot melt adhesive powder or the metal color hot melt adhesive and the transparent coating ink achieve the effect that the metal color and pearlescent color effect is close to the color effect of silk-screen printing. The ink jet stability and the pyrograph color effect can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fabric digital printing, in particular to a method for improving inkjet stability and heat transfer color effect by changing hot melt adhesive powder. Background technique [0002] Screen printing heat transfer has a long history, but the inkjet heat transfer process developed in recent years has made the image more delicate and more convenient to manufacture. However, the inkjet heat transfer process also has some weak links, such as white ink due to its high concentration. Clogged fine inkjet heads, no inkjet printing inks such as metallic and pearlescent, etc. [0003] For the problem of inkjet head clogging, the solutions currently adopted include: selecting a high-quality dispersant in the white ink manufacturing process, so that the small particles of the white pigment are not easy to agglomerate into large particles, and improve the fluency and stability of the ink; The white ink circuit circulati...
