Abstract

The invention discloses a preparation method of environment-friendly inkjet printing dye ink for artificial cotton, which comprises the following steps: adding water and a benzyl vinyl trimethyl ammonium chloride solution into a reactor, adding styrene and butyl acrylate, adding a 2, 2 '-azobis [2-methylpropylamidine]-dihydrochloride solution, and stirring for reaction to prepare a polymer microsphere dispersion liquid; adding caffeic acid, copper chloride and sodium perborate into the polymer microsphere dispersion liquid, heating, stirring and reacting to obtain modified dispersion liquid; adding a reactive dye solution and water into a reactor, adding the modified dispersion liquid, and purifying the mixed liquid through dialysis to prepare a reactive dye / polymer microsphere compound; the reactive dye / polymer microspheres, a dispersing agent, a defoaming agent and water are mixed and added into a mixer for grinding treatment, a viscosity regulator and a pH regulator are added, and the environment-friendly ink-jet printing dye ink for artificial cotton is prepared through stirring. The prepared ink is good in dispersity, high in degree of dyeing and good in color fastness when being used for artificial cotton printing.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an environmentally friendly inkjet printing dye ink for artificial cotton and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for textiles such as daily clothing and home textiles. In addition to high requirements for quality, they also tend to pursue the individualization and diversification of fabrics. Printing is a particularly important process in the production process of textiles, which not only provides consumers with colorful products, but also provides a wide and diverse market for the application of textiles. Traditional printing methods include rotary screen printing, roller printing, etc., which have gradually revealed some shortcomings in the application, such as long process flow, large amount of sewage, and complicated operation procedures. At the same time, ...
