An environment-friendly digital ink-jet direct printing textile ink and method for preparing same

Abstract

An environment-friendly digital ink-jet direct printing textile ink and method for preparing same, the digital ink-jet direct printing textile ink composed of components as follows: pigment paste, connection materials, cross-linking agent, softening agent, solvent, surfactant, bactericide, pH regulating agent, and deionized water. The pigment paste is a mixture of the following components: pigments, ultra-dispersing agent, wetting agent, and deionized water. The preparation method includes: a. mixing the pigments, ultra-dispersing agent, wetting agent, and deionized water into a pigment paste, mixing the pigment paste at high-speed and then grinding it in an ultra-fine nano-grinding machine, to obtain the nano stage ultrafine grain paste; b. mixing the proportioning mixture with the grinded nano stage ultrafine grain paste, high-speed stirring and then filtering to obtain a finished environment-friendly digital ink-jet direct printing textile ink. The inventive printing textile ink does not contain formaldehyde, can be direct digital printed wtihtout plate-making when in use, and has rich color, soft hand feeling, and capability of allowing the digital ink-jet printing textile materials to meet the high environmental and quality requirements.

Description

【Technical field】 [0001] The invention relates to an ink for digital inkjet printing flatbed printers, in particular to a formaldehyde-free, environmentally friendly digital inkjet direct printing textile ink and a production method thereof. 【Background technique】 [0002] In the traditional textile printing technology, printing on textiles requires pre-plate making, and some printing processes require pre-treatment and post-treatment, and water pollution problems will occur in the process of plate-making or pre-treatment and post-treatment. In addition, the traditional textile printing process needs to be carried out in batches, which makes high requirements for printing production technology and finished product quality. [0003] Digital inkjet printing technology is a new textile printing technology, which uses special dye ink or pigment ink to print directly on textiles through inkjet printers. Dye-based digital inkjet printing inks are divided into reactive dye-type, a...

Problems solved by technology

At present, sublimation digital printing using disperse dye inks has been widely used, but this printing method must print the pattern on a special sublimation paper and then perform sublimation transfer printing, and it is only limited to high-temperature resistant polyester fabrics. It cannot be used on some fabrics that are not resistant to high temperature such as pure cotton, and whether it is using reactive ink or acid ink for digital inkjet printing, the textile must be pre-treated and post-treated, and the light fastness and washing fastness degrees are relatively poor
