Digital printing is printing with digital technology. With the development of computer technology, digital printing technology is a new and high technology product which integrates mechanical, computer, electronic and information technology. The emergence and continuous improvement of this technology, to the textile printing and dyeing industry has brought a new concept, its advanced production principle and means, to the textile printing and dyeing brought an unprecedented development opportunity.
Digital direct printing and digital heat transfer printing.
Digital direct printing, which means: using a digital printer to directly print out the patterns you need on a variety of materials.
On the other hand, digital heat transfer printing requires the printing pattern to be printed in advance on special paper, and then transferred to various materials through heat transfer printing, such as: t-shirts, underwear, sportswear and other clothing.
At present, there are four main types of digital printing:
(1) polyester fabric thermal sublimation
(2) pure, hemp, viscose and other active digital printing
(3) nylon acid digital printing
(4) direct spray printing; Such as KORNIT digital direct printing machine
Currently polyester is printed on paper and then heat transferred to cloth. Nylon will do, but there are a few color fastness is not ideal, especially the light. Cotton and silk are usually printed directly on fabrics and cost about twice as much as polyester.
Chemical fiber digital printing is called disperse printing, is first through the digital printing machine to print patterns on paper, in the 180 degrees Celsius heat transfer to the fabric, of course, different fabric temperature is not the same, I just give an example.
Silk, cotton, hemp do digital printing words called active printing, is directly sprayed on the fabric through the digital printing machine, but this fabric is to a treatment, called sizing, or color is not up.
But the white embryo fabric can not be treated, the treatment here refers to: softener, waterproof agent, etc. Because these processing will be dye can not go up the fabric. Softener this kind of processing is in print after a good flower processing. This treatment of fabric sizing is required by printing process, so it is not the same as the treatment mentioned above.
