The four most common pre -processing methods of digital printing

Compared with the traditional printing process, inkjet printing has greatly improved and improved in terms of production technology, cost, and accuracy. Realize multi -color, multi -variety, small batches of printing. It has been applied to cotton textiles, wool textiles, silk, etc. Natural fiber textiles and chemical fiber textiles are widely used, and they have gradually become the mainstream of the printing market.

In order to improve the quality of the final printing and meet the applicability of the subsequent printing process, textiles must be prepared before inkjet printing. This article mainly discusses pre -processing measures during the inkjet printing process of several common textile materials.

Cotton textiles have the advantages of soft luster, soft texture, strong durability, and good coloring. They are the earliest use in traditional printing processes, and the craftsmanship is also the most complete and mature.

Inkjet printing process mainly includes the processing, drying, printing, drying, steaming (120 ° C, 8min, fixed active dye), water washing, drying and other processes. Therefore, as long as cotton textiles are guaranteed to meet the special requirements of the difference between inkjet printing and traditional printing process.

For example, in the process of inkjet printing, the way the ink is transferred to the surface of the cotton textiles is sprayed from the nozzle. Therefore, sodium seas alginate should be added to the pre -roll auxiliary (upper pulp) on the surface of cotton textiles in the early stage of printing. In order to suppress the diffusion of ink sprayed on the cotton fabric and improve the printing accuracy of cotton fabrics. At the same time, it is necessary to ensure that the alkaline environment and the temperature and humidity of the printing workshop in the combination of textiles and inks are within a certain range (the temperature is generally required at 18-25 ° C, and the relative humidity is greater than 50%when printing inkjet printing).

As for the other, as long as it is pure cotton textiles, it can meet the applicability of traditional printing.
