Problems solved by technology

[0003] The traditional inkjet digital printing process often results in washing fastness, dry and wet rubbing fastness, etc. due to ink floating, which cannot meet the requirements of clothing fabric standards.
Although the sizing process is currently used before digital printing, the digital color rendering and fastness are greatly improved. For example, the invention patents CN105350354B and CN104674571A have described this type of treatment method in detail, but this type of method requires a reduction cleaning process. Waste a lot of water resources and pollute the environment
Moreover, even after some fabrics have been restored and cleaned, the color fastness to dry rubbing and wet rubbing still cannot meet the requirements.

Embodiment 1

[0027] A method for enhancing the printing fastness of ink in inkjet digital printing provided by this embodiment is characterized in that it at least includes the following steps:

[0028] In the first step, the water-based transparent paint ink is spray-printed to the position where the pattern needs to be printed on the fabric with a digital printing jet printer to form the first water-based transparent paint ink layer;

[0029] In the second step, the colored ink is spray-printed on the surface of the first water-based transparent paint ink layer with a digital printing jet printer to form a colored ink layer;

[0030] In the third step, the water-based transparent paint ink is spray-printed onto the surface of the colored ink layer with a digital printing jet printer to form a second water-based transparent paint ink layer;

[0031] In the fourth step, the fabric can be cured into a finished product after flash drying.

[0032] Wherein, the thickness of the first water-b...

Embodiment 2

[0040] A method for enhancing the printing fastness of ink in inkjet digital printing provided by this embodiment is characterized in that it at least includes the following steps:

Abstract

The invention belongs to the technical field of refining chemical engineering, and particularly relates to a method for enhancing jet printing fastness in ink jet digital printing. The method at leastcomprises the following steps of S1, enabling a digital printing jet printing machine to jet and spray a water-based transparent coating ink to the position requiring printing patterns on a fabric, and forming a first water-based transparent coating ink layer; S2, enabling the digital printing jet printing machine to jet and spray a color ink to the surface of the first water-based transparent coating ink layer, and forming a color ink layer; S3, enabling the digital printing jet printing machine to jet and spray a water-based transparent coating ink to the surface of the color ink layer, andforming a second water-based transparent coating ink layer; S4, performing flash drying or natural drying on a fabric, and curing, so as to obtain a finished product. Compared with the prior art, themethod has the advantages that the color developing effect of white ink and color ink on the fabric is greatly improved, the printing technology process is shortened, the color fastness of the digital coating ink is improved, and the energy-saving and environment-friendly effects are realized.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a method for enhancing the printing fastness of ink in ink-jet digital printing. Background technique [0002] In recent years, digital printing has developed rapidly as a brand-new printing method, which represents the development trend of the textile printing field in the future. It sprays the pigmented paint ink directly onto the fabric through the printer nozzle, and uses the computer to control the ink to spray onto the textile fabric to form a pattern according to the design requirements. The required image, and has a certain color fastness and vividness. [0003] The traditional inkjet digital printing process often results in washing fastness, dry and wet rubbing fastness, etc. due to ink floating, which cannot meet the requirements of clothing fabric standards. Although the sizing process is currently used before digital printing, the digital color r...
