Inkjet Textile Printer

Traditional textile dyeing methods often involve significant water consumption.
While pigment inks offer a more environmentally friendly alternative, they often compromise on print quality and durability.
Kyocera has developed a revolutionary single-unit printer that addresses these challenges.
By combining the entire textile printing process into a single machine,
Kyocera's solution significantly reduces water usage while producing vibrant and durable prints.
This innovative technology demonstrates Kyocera's commitment to sustainability and
addressing the environmental concerns of the apparel industry.

INTRODUCTION

Aiming to contribute to society
through inkjet printers.

Hayashi:
Our focus was on the new possibilities of inkjet printers. The apparel industry uses large amounts of water in the manufacturing process, and the environmental impact of overproduction and the disposal of large amounts of inventory has become a major problem for society. We realized that if we could create a new inkjet technology by combining the Kyocera Group's capabilities in inkjet printhead development, digital product development for MFPs and printers, and chemical material development, we could contribute to reducing the environmental impact of the apparel industry and shortening delivery times.

Maruta:
Kyocera originally had a 50% share of the textile printing inkjet market with its printer printhead* and had accumulated solid know-how and technology. However, the textile printing industry was shifting from analog to digital,

and society as a whole was becoming increasingly paperless, so a new development was needed. We decided to try something new, thinking that there must be more that inkjet printers could do, as well as from the perspective of the company's growth.

Hotani:
As we reexamined the basic technology, we realized that digital textile printing could address the apparel industry's environmental impact problem. For example, the garment production process suffers many losses, such as the enormous amount of water consumed in the printing process that uses dyes and a large amount of disposed clothing. With the goal of contributing to society through this initiative, the entire team has been working together to promote the project.

SOLUTION

Digital textile printing technology
has the potential to reduce
environmental impact.

Hayashi:
In a nutshell, this project is about the development of a printer that can print on fabrics for clothing using digital technology.  Pigment not only reduces the environmental impact mentioned earlier but also allows for the easy printing of delicate images with a short delivery time. Furthermore, it can significantly shorten the conventional processes in the apparel supply chain and print only the minimum necessary amount, so many benefits can be expected not only for the global environment but also for those involved in manufacturing.

Hioki:
Using dyes requires a very long process to print the textile. The fabric is repeatedly soaked in the dye solution and then dried, and then steamed, and further rinsed in order to fix the color. This process uses a lot of water, and the colored water is discarded, which has been seen as an environmental impact problem. With pigments, however, printing can be done in a short period of time because the process is completed by placing the colorant particle on the cloth and adhering it with resin. Water, fibers, and other materials that would otherwise be wasted can be reduced, and since adhering is only done by heating, energy costs are also low, enabling more environmentally friendly printing in any case.

TECHNOLOGY

Solving problems by bringing together technologies from various fields. 

Hioki:
First of all, we developed a new special ink to address the issues of inferior color and texture found in pigment inks. The new high-performance pigment ink meets the standards of the apparel industry. We also introduced an all-in-one system that allows for special processing before and after printing to be completed with a single printer.

Kobayashi:
In my role, I was responsible for developing the new printhead. Our goal was to create a printhead that could discharge large amounts of liquid accurately and consistently. Additionally, we designed the printhead to circulate the ink within itself, addressing the issue of pigment ink drying out easily, which is considered groundbreaking in the industry.

Hotani:
In mechanical design, we faced the challenge of bringing an unprecedented concept into reality. We overcame these challenges by combining technologies from various fields, not limited to the development of the printhead and ink, but also in controlling the circulation system.

Fortunes such as great teams and products are found beyond honing a skill.

Hioki:
Although our development is in its final stage, we are still in the process of improving it through continuous trial and error. We will continue to evolve it while reflecting user feedback, and we hope to create a product that will be appreciated by many people.

Hotani:
Yes, we have no choice but to go forward believing in the path we think is the right one, as we are just now starting out in the world. I would like to solve problems one by one while delivering happiness to society.

Kobayashi:
I also have a strong desire to spread this printer throughout the world. I would like to help spread the use of this printer by doing my utmost to develop a printer printhead that is easy to use, reduce costs, and so on.

Maruta:
While I want the printer to be released quickly so that more people can use it, I also value the quality control system. There must be no inadequacies in listening to customers' opinions or in creating a system to deal with

defects. New reforms in manufacturing are also necessary, and we will continue to take on challenges, including technological innovation, while keeping a medium- to long-term perspective.

Hayashi:
My immediate goal is simply to increase the number of printed patterned clothes in the world. I would be happy if this printer enables more people to enjoy wearing fashionable clothes with the patterns of their choice. As a future goal, we are considering expanding the functions of this printer to maximize its potential as a inkjet textile printer. We would also like to develop printing technology further and create innovations in digital printing in many fields, not only in clothing.
