Abstract

The present invention provides a multi-level structure based composite particle modified inkjet printing coating ink, which comprises the following components in parts by weight: 3-9 parts of color paste, 5-8 parts of modified multi-level structure composite particles part, 0.1-0.6 part of surfactant, 0.3-0.5 part of ethylene glycol, 1-3 part of polyvinyl alcohol, 0.15-0.25 part of pH regulator, 10-20 part of deionized water; The particles are nano-zirconia composite particles coated with graphene nanosheets, the particle size is 60-80nm, and the surface is modified by polymer. The paint-type ink for inkjet printing disclosed by the invention has good stability and is suitable for inkjet printing of various fabrics. After inkjet printing, the pattern of the fabric is clear, the softness is good, the color fastness is high, and the mechanical properties of the fabric are also good. 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...
