Paperless digital printing

Paperless digital printing can consume high-level products that are difficult to consume with traditional printing techniques. Regarding natural fabrics such as cotton, due to the hydrophilic nature of their fibers and the hydrophobic nature of dispersed dyes that can be used for digital printing, it is difficult to separate the two. Therefore, digital printing cannot be directly suspended for natural fabrics. However, digital printing of natural fabrics can be completed through the action of bridging agents. However, this paper-based digital printing process still has some shortcomings. At the same time, paperless digital printing is the process of making dyes into printing paste, and then printing patterns on a special substrate. After the substrate is attached to the fabric and heated, the patterns on the substrate are transferred and fixed on the fabric, resulting in printing waste.
As a novel textile printing process, paperless digital printing technology has played an important role in textile printing, and its printing products are also highly favored by consumers.
Not using paper, nor generating indirect water consumption and pollution caused by paper consumption, greatly reducing environmental pollution, in line with the country's sustainable development strategy. More importantly, the paperless digital printing process saves precious energy (such as water resources) from the source, and nearly 50% of the cost of printing and dyeing consumption is energy consumption. Saving energy means reducing consumption costs.
The printed patterns have the characteristics of precision, clarity, rich layering, and naturalness, which can print products similar to photos and painting styles. Firstly, digital printing with paper requires paper consumption. For example, printing 1m of cloth requires 1m of paper, which not only consumes a large amount of paper and increases consumption costs, but also indirectly consumes water and energy, and can cause environmental pollution; Secondly, ordinary paper-based digital printing can only print polyester fabrics and cannot be printed on natural fiber fabrics such as pure cotton, which greatly limits its application range.
The paperless digital printing process has undergone nearly 10 years of research and development, and with the support of the National "Tenth Five Year" 863 Plan, after three years of research and development, a breakthrough has been achieved in the field of paperless machines. Bridging agents are usually made of non-toxic and biodegradable raw materials. Before printing, the bridging treatment of fabrics such as silk, pure cotton, and polyester cotton can be suspended, allowing one end of the bridging agent to separate from the fiber and the other end to separate from the dispersed dye. This is like building a bridge between the dispersed dye and the natural fiber, thus completing the digital printing of natural fiber fabrics, expanding the scope of digital printing of fabrics, And make the main indicators of printing reach or exceed national standards. Here, special substrates can be repeated
Furthermore, its plate making fees are relatively expensive and cannot meet the needs of personalized, small batch, and multi variety development.
In order to ensure the industrial consumption of digital printing, the central link is the development of paperless digital printing machines. It is necessary to consider various possible problems and difficulties in advance and deal with them. As usual, the prototype of paperless digital printing machines has successfully stopped debugging and operation, with good results. It will lay a good foundation for the success of paperless digital printing technology, which fully proves the ideal feasibility of paperless process industrialization, It will definitely become a major development direction for future digital printing. Its main characteristics include: no need for steaming, color fixation, soap washing, and water washing, no consumption of steam, coal, water, paper in the printing process, and no generation of sewage in digital printing.
