Solvent type disperse dye ink-jet printing ink and preparation method thereof

Abstract

The invention provides a solvent type disperse dye ink-jet printing ink and a preparation method thereof. The ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dye, 1 to 15 percent of dispersant, 0.5 to 15 percent of resin and 60 to 95 percent of organic solvent. The preparation method comprises the following steps of: adding 1 to 15 percent of dispersant and 0 to 10 percent of resin into the organic solvent, and emulsifying the mixture for 20 to 60min, adding 1 to 8 percent of dye into the mixture, grinding the mixture for 8 to 40h, and obtaining a disperse dye color paste; and adding 10 to 80 percent of disperse dye color paste and 0 to 10 percent of resin into the organic solvent, and filtering the mixture with a millipore filter between 0.2 and 2 mu m to obtain the solvent type disperse dye ink-jet printing ink. The ink has the advantages of good printing smoothness, bright lustre of patterns, and excellent sunlight fastness, washing fastness and rub resistance, and can be widely applied to multiple kinds of wide, high-speed and solvent type digital printing equipment; and the preparation method is simple and practical.

Description

technical field

[0001] The invention belongs to the field of ink-jet printing ink and its preparation, in particular to a solvent-type disperse dye ink-jet printing ink and a preparation method thereof. Background technique

[0002] With the development and popularization of computer technology, inkjet printing technology can be widely used in various fields such as document printing, indoor and outdoor advertising inkjet printing, digital printing and textile inkjet printing. Especially in the textile industry, inkjet printing can save the production steps of printing screen, so it can save a lot of time and cost, especially for the situation of changing patterns and shapes, inkjet printing can achieve the required changes in a short time . In addition, inkjet printing inks for textiles must have good stability, high color fastness and washing fastness, etc.

[0003] For polyester fabrics, the inks used in inkjet printing can be divided into two categories according to th...
