Problems solved by technology

Although resin and cross-linking agent have been added in the above-mentioned disclosed technology, because of the complex composition of paint ink or pigment ink, resin and cross-linking agent can not strengthen the fixation fastness of paint or pigment particles and textile well, and sometimes have a negative impact on spray ink. The printing performance of the ink will be adversely affected, such as increasing the viscosity of the paint or pigment ink system, which will easily cause the instability of the paint or pigment ink system after dilution with water and affect the normal ejection of the ink

Abstract

The invention discloses a water-based pigment black with high color fastness and its preparation method and application. Firstly, the small particle size pigment is obtained by grinding with an auxiliary agent, and then an adhesive and a crosslinking agent are added to form a packaged pigment, and the pigment is further ground , to achieve the technical effect that the particle size is less than 100nm. It is the first time to obtain such a small particle size pigment liquid, which can maximize the role of the binder / crosslinking agent in fixing the organic pigment particles. After diluting into inkjet ink, the machine is improved. The combination fastness of pigment particles on the fiber can obtain excellent color fastness.

Description

technical field [0001] The invention relates to a printing ink preparation technology, in particular to a water-based pigment black with high color fastness and its preparation method and application. Background technique [0002] The technical content involved in the coating / pigment inkjet printing of textiles includes: [0003] (1) Adjust the rheology of paint ink or pigment ink: For example, the patent application number CN201711050546.8 discloses the use of water-based resin, pigment paste, diethylene glycol, ethylene glycol monobutyl ether, isopropanol, OP- 10 Paint inks composed of emulsifiers, surfactants, defoamers, leveling agents, and preservatives. It is believed that paint inks are bright in color, have good light fastness and washing fastness, and the printing process is completed in one step without pretreatment and After washing, it completely solves the waste water discharge caused by printing and dyeing. Obviously, the modification technology of this kind ...
