A blue light curable ink composition for textiles and digital jet printing curing method thereof

Abstract

The invention relates to the technical field of light curing ink, and in particular relates to a blue light curing ink composition for textile and a digital jet printing and curing method of the blue light curing ink composition. The blue light curing ink composition for textile comprises a first component and a second component, wherein the first component comprises oligomer and active diluent, and the oligomer accounts for 40-60wt% of the total weight of the oligomer and the active diluent; the second component comprises 0.25-1wt% of blue light initiator, 0.25-1.5wt% of activating agent, 0.1-5wt% of coloring agent and 0.1-1wt% of dispersion stabilizer by taking the weight of the first component as 100%. According to the blue light curing ink formulation and the digital jet printing processing method of the formulation, monomer and the oligomer are used for replacing macromolecule adhesive, so that the ink is guaranteed to have good stability and fluidity in the digital jet printing process; after digital jet printing, polymerization crosslinking between the monomer and the oligomer can be rapidly triggered on the surface of the fiber fabric by the ink on the printed fabric within a few minutes, even tens of seconds under the irradiation of blue light.

Description

technical field [0001] The invention relates to the technical field of light-curable ink, in particular to a composition of blue light-curable ink for textiles and a digital jet printing curing method thereof. Background technique [0002] Digital inkjet printing of textiles has revolutionary significance to traditional printing processing. However, in the dye-based digital inkjet printing process, post-processing such as steaming, water washing, and drying is still required, and there are problems of water consumption and energy consumption. In addition, due to the affinity of dyes to fibers, dye-based digital printing has printing limitations on substrates and cannot meet the printing requirements of multi-component blended fabrics. It is an effective way to solve the above problems to use pigment ink instead of dye ink in digital inkjet printing. However, due to the macromolecular binder contained in the paint ink, it is very easy to cause nozzle clogging and affect the...

In addition, the patent does not describe in detail and objectively test and evaluate the photocuring process after printing and the wearing performance of digitally printed fabrics.

[0006] In addition, there are many patent reports on UV-curable coating inks applied to the surfaces of various materials such as plastics, steel, glass, and wood, such as "a radiation-curable ink that can directly spray ink on the surface of UV-curable coatings and Its preparation method" (CN102558963B), "a kind of ultraviolet curing ink and its preparation method" (CN102286230B), "a kind of ultraviolet curing ink" (CN103102741A), etc., these patents are mostly applied to the surface of hard materials, and the formula needs By adding a high proportion of multifunctional monomers or resins, the cured film can achieve higher hardness and strength, so it is not suitable for flexible textiles, such as flexibility, elasticity, and toughness.
