Abstract

The invention provides a novel special gel antimigrant superclear for digital printing pigment ink and a preparation method of the gel antimigrant superclear. The novel special gel antimigrant superclear comprises nano-silicon sol, glucose modified gel, an auxiliary and a solvent, and the specified preparation method comprises the following steps: (1), adding a silicon precursor into an ethanol water solution, stirring uniformly, dropwise adding an ethanol water solution containing an acid catalyst, mixing, and rapidly stirring to obtain the nano-silicon sol; (2), adding glucose, methacrylic acid and acrylamide into the solvent, stirring at room temperature, further adding ethylene glycol dimethacrylate and ammonium persulfate, heating and stirring, and cooling to room temperature to obtain the glucose modified gel; (3), adding the glucose modified gel prepared in the step (2) and the nano-silicon sol prepared in the step (1) into a solvent containing a dispersing agent, regulating the PH value of the solution, stirring, diluting, slowly dropwise adding a cross-linking agent and an initiator, heating and stirring, and then leaving to stand to obtain the novel special gel antimigrant superclear for the textile pigment ink.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a special gel anti-swimming agent for digital printing paint ink and a preparation method thereof. Background technique: [0002] Digital inkjet printing of textiles is a promising technology with good development prospects. Among them, inkjet printing with pigments has the advantages of short process flow, wide application range, energy saving and environmental protection. However, the bleeding of paint ink not only affects the clarity of inkjet printing patterns on fabrics, but also significantly reduces the color depth and vividness of printing. Although the color depth and vividness of the printed pattern can be improved to a certain extent by padding the fabric pretreatment or applying multiple inks, but the printing cost will be greatly increased, and the effect obtained is limited. Therefore, it is necessary to process the coating ink to increase th...
