Abstract

The invention discloses water-based ink-jet printing pigment ink for textile products as well as a production method thereof. The water-based ink-jet printing pigment ink for textile products mainly comprises water-based microcapsule pigment paste, a wetting agent, a preservative and deionized water. The production process is simple, the cost is low, energy conservation, emission reduction and nopollution in the processing process are realized, and the environmental protection requirement is met; and ground and crushed pigment is coated with ink by a microcapsule technology to self-make functional polymeric dispersant, so that secondary agglomeration of pigment particles is effectively avoided and the ink has high dispersing stability and storage stability.

Description

technical field [0001] The invention relates to a textile ink, in particular to a textile water-based inkjet printing pigment ink and a production method thereof. Background technique [0002] Digital inkjet printing technology is a brand-new textile printing technology. The inkjet printing system is controlled by a computer to directly spray ink onto the surface of cotton, linen, silk, chemical fiber and other fabrics to print various patterns and patterns. Compared with the traditional printing technology, the digital jet printing process has five characteristics: high production efficiency, high product quality, low energy consumption, low pollution, and arbitrary batch production. [0003] Inkjet printing ink is one of the important contents of digital inkjet printing technology. Like other printing methods, inkjet printing ink is the main consumable material in digital inkjet printing production. At present, the development of inkjet printing ink has become an indispen...
