Abstract

The invention discloses a digital printing method. The digital printing method comprises the steps of fabric pretreatment, drying, physical adsorption agent spraying, drying before printing, inkjet printing, drying after printing, steaming, washing and drying. Based on the principle that a porous surface is formed on fabric by adopting calcium carbonate or mesoporous silica or mesoporous titania as a physical adsorption agent, and bleeding phenomena can be reduced, the physical adsorption agent is sprayed in advance according to printing patterns, a closed layer is formed in an interface between an area needing to be printed and an unprinted area of the fabric to stop dye ink from bleeding towards the unprinted area.

Description

technical field [0001] The invention relates to the field of jet printing, in particular to a digital printing method. Background technique [0002] With the overall improvement of today's world economic level, people's demand for clothing, textiles, etc. is becoming more and more individualized and diversified, which has brought a certain positive impact on the traditional textile industry, requiring that the manufacturing field must also be transformed into Multi-variety and small batch production process. The emergence of digital printing technology just meets and adapts to this new market demand. Digital printing technology is the product of the integration of advanced technologies such as precision machinery, computer and optoelectronic integration, and is a major breakthrough in traditional printing technology. As customers' demand for digital printing products of different fabric types, especially digital printing products of high-grade fabrics, is increasing signifi...
