A new method of dye direct-injection ribbon digital printing

Abstract

The invention discloses a novel dye direct-injection ribbon digital printing method, which comprises the following steps: the first step is to use the ribbon conveying mechanism to transport the ribbon; the second step is to dye the direct-injection printing and drying; the third step is to print The webbing after drying is received; the fourth step is to allow the dye to react with the webbing fiber, and post-printing treatment. In the novel dye direct-injection digital printing method for webbing of the present invention, the digital direct-injection printing of webbing relies on different nozzles to spray different basic color dyes to a certain position of the webbing, and adjusts the dyes of various basic colors. Proportioning to produce color at this location; since the dye is chemically reacted to bond to the fibers of the webbing, the performance of the printed pattern will not be affected by the adhesives used in conventional webbing screen printing.

Description

technical field [0001] The invention relates to a novel dye direct-injection ribbon digital printing method, which belongs to the field of textile digital printing. Background technique [0002] At present, the printing methods usually used for ribbon printing are as follows: (1) Screen printing, that is, through the extrusion of a scraper, the color material is transferred to the surface of the ribbon through the through hole on the screen to form a pattern printing Method; each color of screen printing needs an independent screen, when printing multi-color patterns, in order to avoid screen positioning offset caused by color matching (two or more colors are overlapped and printed together) or exposed bottom ( In the case of misalignment of different colors, the printed place is not printed and the background color is exposed), the screens of all colors must have the same positioning reference, which is difficult to do in the narrow size range of the webbing, so the screen ...

[0002] At present, the printing methods usually used for ribbon printing are as follows: (1) Screen printing, that is, through the extrusion of a scraper, the color material is transferred to the surface of the ribbon through the through hole on the screen to form a pattern printing Method; each color of screen printing needs an independent screen, when printing multi-color patterns, in order to avoid screen positioning offset caused by color matching (two or more colors are overlapped and printed together) or exposed bottom ( In the case of misalignment of different colors, the printed place is not printed and the background color is exposed), the screens of all colors must have the same positioning reference, which is difficult to do in the narrow size range of the webbing, so the screen of the webbing It is difficult to print more than two multi-color patterns in screen printing; because the dyeing process is usually complicated, the color materials used in the screen printing of webbing can be combined with the webbing fiber through chemical additives such as adhesives. Coloring materials, such as ink, paint, silica gel, etc.; since the webbing screen printing uses the coloring material combined with the webbing fiber through chemical additives such as adhesives, the post-printing treatment is relatively simple: high temperature drying Yes; although the post-printing process is simple and efficient, there are also certain shortcomings: the colorant is combined with the webbing fiber through chemical additives such as adhesives, so the washing resistance will be slightly worse than that of the dye; The coloring material combined with the webbing fiber through chemical additives such as adhesives can only exist on the surface of the webbing, so the hand feeling of the printing position will be rough; while the dye molecule is small and can penetrate into the interior of the webbing fiber and react with it, so the dye It will feel better as a color printing

(2) There is also a special printing method for polyester webbing, heat transfer printing with transfer paper as the medium: transfer the disperse dye from the transfer paper by overheating transfer (first print the printed pattern on the transfer paper with disperse dye) Transfer to the webbing; the post-printing treatment is relatively simple: just dry at high temperature; although the post-printing treatment process is simple and efficient, there are also some cases where the sublimation fastness and washing fastness of disperse dyes will be poor The problem
