Digital-printing ink-jet ink made of nano pigment and its making process

Abstract

The invention relates to a nanopigment digital printing ink-jet ink, which consists of the following components: nanopigment dispersion color paste; humectant; descaling agent; bactericidal agent; control agent for PH value; surface activator; resin and deionized water. The manufacturing technique includes the following steps: (A) predispersing and grinding the pigment according to the fineness requirement to less than 200 nanometers of D90 to prepare nanopigment dispersion color paste; (B) mixing humectant, descaling agent; bactericidal agent, control agent for PH value, surface activator, resin and deionized water at the normal temperature and sufficiently stirring to obtain the mixed solution; (C) adding the nanopigment dispersion color paste into the mixed solution obtained by step (B) and sufficiently stirring to obtain mixed solution; (D) stewing and curing the mixed solution obtained by step (C) to obtain the aged mixed solution; (E) filtering the aged mixed solution obtained by step (D) by filter membrane to obtain the end product.

Description

technical field

[0001] The invention relates to a digital ink-jet ink and a production method thereof, in particular to a nano-pigment digital printing ink-jet ink and a production process thereof. Background technique

[0002] Textile digital inkjet printing has been more and more widely used in the textile industry. This method can save the printing plate-making process and shorten the production process; it can realize direct printing of digital patterns, which is novel and convenient; it can reduce the amount of pigments, produce no waste dyes, and shorten the post-processing process at the same time, becoming a low-cost, low-pollution textile Printing production methods.

[0003] Digital inkjet printing is mainly suitable for printing cotton with reactive dye ink, printing silk and wool with acid dye ink, and printing chemical fiber fabric with disperse dye ink. However, the existing fabrics are often blended, and a single ink cannot complete jet printing, so it is ne...
