Abstract

The invention provides weak-solvent ink for spinning ink jet. The weak-solvent ink is prepared from the following components in parts by mass: 5 percent to 20 percent of an organic dispersion dyestuff, 2 percent to 10 percent of a dispersant, 5 percent to 20 percent of a resin connecting agent, 2 percent to 5 percent of a surfactant, 1 percent to 10 percent of other auxiliary agents and 60 percent to 80 percent of an organic weak solvent. The weak-solvent ink provided by the invention has the advantages of good dispersity, high stability, uneasiness of blocking a nozzle, good ink jet continuity and bright color. The invention also aims at providing a method for preparing the weak-solvent ink for the spinning ink jet.

Description

technical field [0001] The invention relates to the field of inks, in particular to an eco-solvent ink for textile inkjet and a preparation method thereof. Background technique [0002] Inkjet inks can be roughly divided into water-based inks, solvent-based inks and UV-curable inkjet inks that have just been developed in recent years according to their main components. Water-based ink can achieve zero VOC emissions, and the cost is low. However, due to the slow volatilization of water, some disperse dyes are insoluble in water, which is easy to cause the aggregation and precipitation of dye particles; the main component of solvent ink is organic solvent, generally Using ester and ketone solvents, the medium is first swelled in the process of combining with the medium, and then fused to tightly combine the colorant in the ink with the substrate, so the solvent-based ink does not require the medium to be coated, and its volatilization The speed is fast and can meet the requir...
