Paperless digital printing technology
Paperless digital printing can consume high - level products which are difficult to consume in traditional printing process.About the natural fabric such as cotton, because its natural fiber is hydrophilic, and the dispersive dyestuff that can sufficient digital printing is hydrophobic, both hard leave, so natural fabric cannot stop digital printing directly.However, the digital printing of natural fabric can be accomplished by bridging agent.However, there are still some drawbacks to the paper-based digital printing process.At the same time, paperless digital printing is to make dyestuff into printing paste, and then print the patterns on a special base material through printing. After the base material and fabric are pasted together, the patterns on the base material are transferred and fixed on the fabric, resulting in printing waste.
As a novel fabric printing technology, paperless digital printing technology has played an important role in textile printing, and its printing products are also popular among consumers.
No paper consumption, no indirect water consumption and water pollution caused by paper consumption, greatly reducing environmental pollution, in line with the country's sustainable development strategy.What's more, paperless digital printing saves precious energy resources (such as water resources) from the source, and nearly 50% of the cost of printing and dyeing is energy consumption. Saving energy means reducing the cost of consumption.
Printed patterns with fine, clear, rich, natural characteristics, can be printed similar to photographs and painting style of products.First of all, digital printing with paper will consume paper. For example, if you print 1m cloth, you will use 1m paper. This will not only consume a large amount of paper, but also increase the consumption cost.Second, ordinary digital paper printing can only be printed on polyester fabric, can not be printed on natural fiber fabric such as cotton, so its application range is greatly restricted.
The paperless digital printing technology, after nearly 10 years of research, and under the national "15" 863 program, after three years of research, has achieved a breakthrough in paperless machine.Bridging agent made from ordinary with non-toxic, biodegradable materials, printing can be in advance before the real silk, cotton and polyester-cotton fabric such as suspension bridge disposal, make one end of the bridging agent and fiber separation, on the other side with disperse dye separation, it's like in disperse dye and set up a bridge between natural fiber, thus complete natural fabrics digital printing, extend the scope of digital printing fabric, and make the printing of the main indexes reach or exceed nation standard.Here, special substrates can be repeated
Still have, its make edition cost is more expensive, cannot comply with individuation, small batch, much breed expand demand.
In order to ensure the digital printing industrial consumption, its central part is a paperless digital printing machine development, it must think in advance to all possible attacks the title of the topic, difficulties and disposal, always, no paper prototype of digital printing machine has successfully stopped the debugging operation, good effect, it will be to the success of the paperless digital printing technology has laid a good foundation, thus fully proved feasibility, paperless technology industrialization has the ideal will be digital printing of a main direction in the future.Its main characteristics are: no need of evaporation and fixation, soaping and washing, no consumption of steam, coal, water, paper in the printing process, no sewage produced digital printing.
