Abstract

The invention discloses a pigment ink for inkjet printing of high fastness textile and a preparation method thereof. The ink comprises the following components by mass percent: 30-50% of pigment / branched polymer nano composite particle dispersoid, 10-50% of water soluble cosolvent, 1-5% of non-ionic surfactant, and the balance of deionized water. The preparation method comprises the following steps: sequentially adding the pigment / branched polymer nano composite particle dispersoid, a water-soluble cosolvent and a non-ionic surfactant into the deionized water in proportion, mixing uniformly, stirring by a stirrer at a speed of 500-1000rpm (revolutions per minute) for 20-40 minutes, regulating pH value of the ink to be 7-9, and filtering by virtue of a 500nm microfiltration membrane so as to obtain the coating ink. The ink needs no adhesive, the grain size of the pigment particle in the ink is less than 200nm, and the ink has good storage stability; after jet printing, the textile is baked so as to obtain good color fastness, thus improving the brightness.

Description

technical field [0001] The invention relates to the technical fields of fine chemical industry and material science, in particular to a pigment ink for ink-jet printing of textiles with high fastness and a preparation method thereof. Background technique [0002] Textile inkjet printing technology is a new printing technology that integrates computer network system, digital processing and information system, precision machining and high-quality fine chemical materials. This technology does not require plate making and can be printed directly on fabrics. Printing precision, realize small batch, multi-variety, multi-color printing, has broad development prospects. Ink is an important consumable for textile inkjet printing, and its quality is closely related to the quality of printed fabrics. The research and development of ink is a key factor to promote the progress of textile inkjet printing technology. At present, the ink used for inkjet printing of textiles is still mainly...
