Problems solved by technology

Existing pigment-based inks generally have poor color fastness to rubbing, especially wet rubbing color fastness. In order to overcome this defect, water-based resins such as polyacrylates and polyurethanes are generally used as film-forming agents at present, but their film-forming The properties and rheology are far from meeting the requirements of the inkjet printing ink system, and the corresponding printed fabric feels hard; and in the corresponding production process, amines are added as pH regulators and aromatic alkanes as dispersants, resulting in The pigment ink produced will contain aromatic amines that are carcinogenic to the human body
In order to improve the above problems, the existing method is to add a large amount of strong polar solvent as a dispersant and main solvent, and modify it into a weak solvent pigment ink. Such ink needs to pretreat the fabric before printing during use. , Heating and fixing the color of the fabric after printing will corrode and damage the nozzle and fabric due to the strong polarity of the solvent, and there will be a large amount of VOC emissions, which will damage human health

Abstract

The invention relates to ink and in particular relates to water-based nano pigment ink for textile printing. According to the formula, the ink mainly comprises the following components in parts by weight: 12.4-18.6 parts of water-based pigment slurry, 9.5-14.9 parts of a water-based resin, 5.3-9.6 parts of a quick-dry type solvent, 5.4-9.8 parts of a moisturizing solvent, 0.5-2 parts of a surfactant, 0.05-0.2 part of an antibacterial agent and 50.9-65.55 parts of deionized water. According to the ink disclosed by the invention, textiles do not need to be preheated and heated, and the ink refers to healthy and environment-friendly water-based nano pigment ink which can be directly printed on the textiles. Moreover, a digital ink-jet printing textile prepared by the ink has excellent color fastness to washing, color reduction rate and excellent handfeel.

Description

technical field [0001] The invention relates to an ink, in particular to a water-based nano pigment ink for textile printing. Background technique [0002] Digital inkjet printing is to input the required pattern into the computer through digital input, and after computer color separation processing, the inkjet printing machine is driven by computer software to directly print the ink on the textile, and it is completed after certain post-processing. printing process. Compared with traditional printing technology, inkjet printing technology has the characteristics of high product quality, low energy consumption and low pollution, and is the main development direction of the printing field in the future. Ink is the key material of inkjet printing, which determines the quality of inkjet printed fabrics. Therefore, the development of inkjet printing ink is an indispensable part of the development of inkjet printing technology, and has become a research hotspot in the field of ...
