Abstract

The invention discloses an aqueous jet ink printing pigment ink for textile and a production method thereof. The aqueous jet ink printing pigment ink for textile mainly consists of aqueous microcapsule pigment paste, a wetting agent, preservatives and de-ionized water. The invention has simple production process and low cost, and saves energy, reduces emission and accords with the requirements ofenvironment protection without pollution in the production process. The microcapsule technology is adopted to coat the grinded and comminuted pigments to make a functional high molecular dispersing agent, thereby effectively preventing the pigment particles from agglomerating for the second time and ensuring that the ink has better dispersing stability and storage stability.

Description

Technical field: [0001] The invention relates to an ink and a production method thereof. Background technique: [0002] Digital inkjet printing technology is a brand-new textile printing technology. Through the computer-controlled printing system, the ink is directly sprayed 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 indispensable part of the development of inkjet printing technology, and has beco...
