Environmentally-friendly digital inkjet textile printing ink with reactive dye and preparation method thereof

Abstract

The invention relates to environmentally-friendly digital inkjet textile printing ink with reactive dye and a preparation method thereof, and the ink is a composition formed by the following components by weight percent: 12-90.6% of deionized water, 5-40% of wetting agent, 0.2-5% of surface active agent, 0.1-2% of pH regulator, 0.1-1% of disinfectant, 1-10% of softener and 3-30% of the reactive dye. The preparation method comprises the following steps: placing all the components into a stirring container sequentially, stirring, and then using a filter membrane to perform filtration many timesso as to prepare an ink finished product. The ink can be combined with cotton, wool and silk textiles without surface treatment under the conditions of being salt-free and alkali-free completely, thereactive dye is not hydrolyzed completely during the dyeing process and the storage process, the dyeing rate is high, the ink can be stably stored for a long time, the dyeing without waste water emission is realized, and the water consumption and the pollution of printing with the reactive dye are reduced.

Description

【Technical field】 [0001] The invention relates to a digital ink-jet textile printing ink, in particular to an environment-friendly digital ink-jet textile printing ink with reactive dyes and a preparation 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. Using reactive dye inks for digital inkjet printing on cotton, linen and other textiles can achie...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problems of easy hydrolysis, low dye uptake and long-term storage stability of traditional inkjet textile printing inks with reactive dyes, and provides a reactive dye that is completely non-hydrolyzed during dyeing and storage and has high dye uptake , The ink has a long stable storage time, realizes dyeing without wastewater discharge, and greatly reduces the water consumption and pollution of reactive dye printing.
