Abstract

The invention provides an inkjet printing method by using coating-type ink with organic-inorganic coated pigment color paste. The method comprises the following steps that gelatin is used as a wall material for preparing microcapsule pigment, and carboxylation treatment is conducted; the pigment is added to an acrylamide monomer emulsion, and ammonium persulfate is added for a reaction to prepareacrylamide-coated microcapsule pigment; a nano titanium dioxide particle layer is deposited on the surface of a polyacrylamide layer, the surface of the polyacrylamide layer is modified with aminoethyl imine propyl polydimethylsiloxane, modified microcapsule pigment is prepared, and the modified microcapsule pigment, a surfactant and deionized water are mixed for preparing the microcapsule pigmentcolor paste; the microcapsule pigment color paste is mixed with ethylene glycol, sodium polyacrylate, polyhexamethylene guanide hydrochloride and deionized water, after filtering and desalting are conducted, the coating ink is prepared, and a fabric is subjected to inkjet printing treatment. The prepared coating ink is good in dispersibility and affinity with fabric fibers, diffusion in the printing process is effectively prevented, and the bright degree of fabric printing patterns is improved.

Description

[0001] Technical field: [0002] The invention relates to the field of digital ink-jet printing, in particular to a method for ink-jet printing using a paint-type ink containing organic-inorganic coated pigment paste. [0003] Background technique: [0004] The traditional printing and dyeing process has the disadvantages of high consumption, high pollution and high emission. However, with the increasing pressure of environmental protection, the digital inkjet printing process was born. Digital inkjet printing is to directly print the graphics and images processed by the computer onto the fabric. The digital inkjet printing system digitizes the required patterns and inputs them into the computer through scanners, digital cameras and other input devices, or directly designs them on the computer through the designer, and then edits them through the computer printing color separation scanning system, and finally uses The computer-controlled micro-piezoelectric inkjet nozzle struc...
