Problems solved by technology

[0003] The traditional white glue uses anionic resin as a film-forming agent. In order to achieve a balance of aggregation and spreading of the subsequent colored ink on the surface of the white glue, a highly absorbent filler can be added to the white glue, so that after the colored ink is printed, It can be immediately absorbed and fixed without bleeding, but the products obtained in this way have the problems of insufficient color depth and poor vividness
In addition, it is also possible to heat the printing platen so that the color ink is placed in a higher temperature environment after printing, and the color ink with a high temperature dries quickly to prevent bleeding. However, in this way, there are insufficient wetting and leveling of the color ink, The print head is easy to clog the problem

Abstract

The invention discloses white glue for paint ink digital printing. The white glue is prepared from, by weight, 20-60% of cation resin, 20-35% of titanium dioxide, 10-20% of auxiliaries, 1-10% of a pH regulating agent and 1-20% of water, wherein the sum of weight percentages is 100%. The white glue has advantages of simple formulation, easiness in raw material acquisition and environment friendliness. The invention further discloses a preparation process of the white glue. The preparation process of the white glue has advantages of simplicity, convenience in operation and short process.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a white glue for paint ink digital printing and a preparation process thereof. Background technique [0002] Digital printing using textile water-based paint ink is a technology with good development prospects. Compared with the currently widely used screen printing technology for clothing fabrics, digital printing technology uses computers to directly output and print patterns without overprinting, and the product Clear pattern, wide range of applicable materials, less ink waste. However, for dark textile fabrics, when digitally printing, it is first necessary to use white glue as a primer, and then print with color ink. However, after the traditional white glue paint is used for priming, there is ink bleeding or agglomeration, which not only affects the clarity of inkjet printing patterns on fabrics, but also significantly reduces the color depth and vividness of prin...
