Water-free reactive dye printing ink and preparation method thereof

Abstract

The invention discloses water-free reactive dye printing ink and a preparation method thereof. The water-free reactive dye printing ink is prepared from the following raw materials in parts by weight:10 to 20 parts of reactive dye, 3 to 7 parts of surfactant, 2 to 6 parts of pH regulating agents, 1 to 3 parts of softening agents, 2 to 4 parts of wetting agents, 1 to 2 parts of antifoaming agents,2 to 4 parts of bactericides, 0.2 to 0.4 part of graphene, 3 to 5 parts of hydroxymethyl cellulose and 20 to 30 parts of deionized water. The water-free active dye printing ink provided by the invention has the high color fixing rate; low-chromaticity sewage is reused; the sewage discharge is effectively reduced. The water-free reactive dye printing ink has the advantages that the preparation process is simple; the operation is easy; the raw material price is low; the raw materials can be easily obtained; no toxicity and no harm exist; the volatility is very low; no irritation is caused on the human body.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and more specifically relates to an anhydrous reactive dye printing ink. Background technique [0002] Simply speaking, the production process of digital printing is to input various digital patterns into the computer through various digital means such as scanning, digital photos, images or computer processing, and then process them through the computer color separation printing system, and then pass them through special RIP software. For its printing system, various special dyes (reactive, disperse, acidic main coatings) are directly spray-printed on various fabrics or other media, and after processing, various high-quality dyes are obtained on various textile fabrics. Precision printed products. [0003] Printing ink is configured by dyes, the most commonly used dyes are reactive dyes, acid dyes and disperse dyes. [0004] Some printing inks currently on the market need to be steamed ...

Problems solved by technology

This process requires a large amount of industrial water and discharges a large amount of industrial wastewater. At the same time, the process of steaming, washing, and drying is long, requires a lot of equipment, takes up a lot of space, and requires a large investment in equipment.

In addition, some commonly used printing inks have poor color fastness after use and are not resistant to water washing. Fixing agents and adhesives need to be added, which affects the quality of the product.
