Thermal foaming or thermal bubble type printer digital printing process using reactive dye ink

Abstract

The invention discloses a thermal foaming or thermal bubble type printer digital printing process using a reactive dye ink; the digital printing process uses the reactive dye ink with high temperature resistance and long survivability; digital inkjet printing of cotton, silk, wool, linen and cotton fabrics can be realized on a thermal foaming or thermal bubble type printer, wherein the cotton, silk, wool, linen and cotton fabrics are not sized by use of a synthetic sizing agent prepared from urea, sodium alginate, nutmeg, cellulose or any paste material as a main raw material; the process is simple in step, less in water consumption, low in energy consumption, economic and environmentally-friendly, and solves the problems, in the prior art, of hydrolysis and alcoholysis of the reactive dye ink when the reactive dye ink passes through a thermal foaming or thermal bubble type printer head and crust formation and ink path blocking for the reason that high temperature of the printer head cause part of the reactive dye ink to be dried and pulverized into powder, and application of the reactive dye ink in the thermal foaming or thermal bubble type printer can be realized.

Description

technical field [0001] The invention relates to a digital printing process, in particular to a reactive dye ink textile digital printing process for thermal foaming or thermal bubble printers, and belongs to the technical field of digital printing. Background technique [0002] Digital printing, also known as digital direct injection printing or digital inkjet printing, uses digital technology to print various textiles. After the editing process, the required pattern is formed, and then the inkjet printer is controlled by the output software, and various special printing inks are directly spray printed on various fabrics, and then undergoes 102°C steam for color fixing, desizing, fading and floating colors, etc. Obtain printed textiles with high-precision patterns. [0003] For the emerging industry of digital textile printing for natural fabrics cotton, silk, wool and hemp, it has been ten years since Spain and Italy took the lead abroad, and there are seven or eight rese...

Problems solved by technology

[0015] The object of the present invention is to provide a reactive dye ink digital printing process for thermal foaming or thermal bubble printers. The digital printing process uses reactive dye inks with high temperature resistance and long viability. or hot air bubble nozzle printing equipment, realize the sizing treatment of cotton, silk, wool, Hemp and rayon fabrics for digital direct-injection printing; this process has simple steps, less water consumption, low energy consumption, and is economical and environmentally friendly. Hydrolysis, alcoholysis, and some reactive dye inks dry and atomized into powder due to the high temperature of the print head, resulting in the formation of rice cakes and blockage of the ink channel.
