Abstract

The invention relates to the field of printing technology, specifically a water-based UV curable ink direct-injection printing process. The direct-injection printing device used includes a mounting seat, and ultraviolet lamps are fixedly installed around the mounting seat. There is an inkjet tube, the bottom of the inkjet tube penetrates to the lower surface of the installation seat, and the inside of the ultraviolet lamp is sleeved with a lamp tube. By setting the regulator, turning the driving gear to make the triangular plate close, and turning the driving gear to different degrees to adjust the luminous flux, so that the passing ultraviolet rays can be ideally adjusted, so that the effect on the curing of the colored coating is more obvious, increasing The curing speed and curing depth of the printing ink, by setting the diffuser, it is convenient to convert the divergent light of the point light source into parallel light, combined with the reflector, it is convenient to pass through the inside of the lamp tube due to the reflection of mercury molecules when the ultraviolet rays touch the ink to be cured. The oblique rays that interfere with the imbalance are refracted again.

Description

technical field

[0001] The invention relates to the field of printing technology, in particular to a water-based UV curing ink direct injection printing technology. Background technique

[0002] The printing process is the process of printing patterns on textiles with dyes or pigments. Printing can be divided into fabric printing, top printing and yarn printing, and fabric printing is the main method. Top printing is used to make mixed-color tweed and yarn. Printing is used to weave special styles of colorful patterned fabrics. Water-based UV curable ink is the most commonly used printing ink in the textile industry. The ink is printed on the base paper through a gravure printing machine, and then the paper is printed on the paper under high temperature and high pressure of the thermal transfer printing machine. The pattern is transferred to the textile of polyester material. Its main components are hot melt adhesive, pigment and some additives. Refers to the radiation rate...

Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Such as Figure 1-Figure 7 Shown, a kind of water-based UV curable ink direct jet printing technique of the present invention, this technique comprises the following steps:

[0030] S1: Put UV curable ink, resin, ethylene glycol and water into the mixing tank according to the ratio of 1.5:1:0.7:3, mix and stir, use electric heating wire to heat 80-100 degrees Celsius during the stirring process, heat for 10 minutes and keep warm 10-20 minutes, the stirring time is 30 minutes, the water content can be controlled during the high temperature heating process, so as to control the consistency of the mixture, and the stirring during the high temperature heating process can facilitate the mixing of UV curable ink, resin and ethylene glycol, so tha...
