How to keep maintenance of White ink digital textile printer?

In the past three years, the government has increasingly strict requirements for white ink direct inkjet printer and textile printing factories. Every factory that meets the standard must have a certain proportion of high-speed industrial digital printing machines. At the same time, the government has also issued various tax policies to encourage the use and research and development of digital printing machines. The textile industry needs sustainable development, and digital printing technology is very necessary.

Requirements for industrial nozzles: 

Digital printing has been in development for more than 20 years, but high-speed digital printing machines have really begun to be accepted by the market only in a short period of 2-3 years in recent years. For digital printing technology, now is the breakthrough period of rapid technological development, and the joint efforts of nozzles, inks, machinery, and integrators are needed to accelerate the maturity and leap of technological improvement. Among many factors, the sprinkler is the leader of the entire technology, so it is even more important.

So, what kind of nozzle can meet the needs of high-speed industrial digital printing? Through research, the following 2 points are the key:

(1) Durability and long service life:

The print head is recognized as the most expensive component in the whole machine. The higher the high-speed production, the more specifications and numbers of print heads. Once the loss of cost is great, digital printing factories require the print heads to be more robust and durable. As we all know, Dimatix nozzles have the characteristics of high full-load cycle, long life, and scratch resistance. Dimatix nozzles are also a nozzle on the market that can be disassembled, repaired and replaced. From then on, the digital direct inkjet printer factory bids farewell to any problem with the nozzle that throws away the era of buying new nozzles.

(2) Realize uniform and stable printing at high speed:

In order for the printing and dyeing factory to exchange the digital printing machine from the inherent production line, it must achieve at least acceptable speed and stability. According to the survey at this year's exhibition, printing and dyeing factories generally accept digital printing speeds of 30-40m/min. But they also emphasized that in printing, to maintain the consistency of inkjet density and stable printing.

The ejection speed of the nozzle and the ability to cooperate with the ink is very critical. For the starlight nozzle, the printing speed of 30-40m/min is not a problem, and the equipment factory has done it easily. For textile water-based inks, especially pigment inks that have received widespread attention, Dimatix nozzles are specially designed for dual ink internal circulation, which circulates 1024 nozzle holes on a single nozzle, and each hole is individually circulated to keep the ink flowing at any time. Take away bubbles and reduce precipitation.

In long-term work, the ink of the cut piece printing machine can print smoothly and stably, reducing the possibility of wire drawing and plugging, and reducing the frequency of maintenance. And even if the machine rests overnight and the internal circulation is turned on the next day, the ink can work normally immediately, reducing the preparation time for starting up.
