Abstract

The invention provides a method of inkjet printing using a paint-type ink containing organic-inorganic coated pigment paste, comprising the following steps: using gelatin as a wall material to prepare a microcapsule pigment and carrying out carboxylation treatment; adding acrylamide In the monomer emulsion, ammonium persulfate is added for reaction to prepare acrylamide-coated microcapsule pigment; a nano-titanium dioxide particle layer is deposited on the surface of the polyacrylamide layer, and then aminoethyliminopropyl polydimethylsilane is modified on the surface Oxane to prepare modified microcapsule pigment, which is mixed with surfactant and deionized water to prepare microcapsule pigment paste. The microcapsule pigment color paste is mixed with ethylene glycol, sodium polyacrylate, polyhexamethylene guanidine hydrochloride and deionized water, filtered and desalted to prepare paint ink, and the fabric is subjected to ink-jet printing treatment. The coating ink prepared by the invention has good dispersibility and good affinity with fabric fibers, effectively avoids bleeding in the printing process, and improves the vividness of fabric printing patterns.

Description

Technical field: [0001] 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. Background technique: [0002] 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 structure directly s...
