Abstract

The invention provides a coating-type ink for inkjet printing based on modification of multilevel-structure composite particles. The coating-type ink is prepared from, by weight, 3-9 parts of color paste, 5-8 parts of the modified multilevel-structure composite particles, 0.1-0.6 part of a surfactant, 0.3-0.5 part of ethylene glycol, 1-3 parts of polyvinyl alcohol, 0.15-0.25 part of a pH regulatorand 10-20 parts of deionized water; the modified multilevel-structure composite particles are nanometer zirconia composite particles wrapped with graphene nanosheets, the particle size of each composite particle is 60-80 nanometers, and the surfaces of the composite particles are subjected to polymer modification. The disclosed coating-type ink for inkjet printing is good in stability and suitable for inkjet printing for various types of fabrics, after inkjet printing, patterns of the fabrics are clear, the fabrics are good in softness and high in color fastness, and the mechanical propertiesof the fabrics are also improved.

Description

Technical field: [0001] The invention relates to a digital printing process, in particular to a coating-type ink for ink-jet printing based on composite particle modification of a multi-level structure and a preparation method and application thereof. Background technique: [0002] With the diversification and development of all aspects of the world, people's spiritual culture and aesthetic needs have been greatly improved. In order to meet the requirements of small batch production, flower patterns, and different performances of printed fabrics, different printing technologies for textiles have also emerged as the times require. pregnancy. There are different classification methods for textile printing, the most common of which are divided by different printing equipment, including: roller printing, flat screen printing, rotary screen printing, transfer printing and inkjet printing, etc. Among them, digital inkjet printing is due to With the advantages of low pollution, lo...
