Digital printing is the most advanced printing technology in the printing industry. The emergence of this technology continues to bring new changes to the printing and dyeing industry. The printing industry also ushered in unprecedented opportunities.

The advantages and disadvantages of digital printing fabrics

Fabrics determine the process, the current digital printing can be divided into four.

(1) Thermal sublimation of polyester fabrics: This is the most popular process at present; because of low investment threshold and simple printing process, general printing plants will be equipped to supplement the screen printing; only one printer and heat transfer machine are required. , And sublimation ink and thermal transfer paper.

(2) Pure, hemp, viscose and other active digital printing; Compared with polyester thermal transfer, active digital printing is more complicated, requiring pre-treatment, printing, steaming, water, qualitative, etc.;

(3) nylon acid digital printing;

(4) Direct-spray printing of paints;

Currently polyester is printed on paper and then transferred to the cloth by heat. Nylon is OK, but the color fastness of several colors is not ideal, especially light. Cotton and silk are usually printed directly on the fabric, which is about twice as expensive as polyester.

Chemical fiber digital printing called dispersion printing, is the first to print the pattern on the paper through a digital printing machine, in the high temperature of 180 degrees Celsius thermal transfer to the fabric, of course, different fabric temperature is not the same, I just give an example.

Silk, cotton, and linen are called reactive printing when digital printing is done. They are printed directly on the fabric through a digital printing machine. However, this fabric needs a process called sizing. It is impossible to go for color.

However, white embryonic fabrics cannot be processed. Here, the treatment refers to softeners, water repellents, and the like. Because these treatments will be dyes do not go fabric. Softeners are treated like this after they have been printed. The processing of the sizing of the fabric is a requirement of the printing process, and therefore is not the same as the aforementioned treatment.
