digital printing technology
Digital direct jet printing: it is a method of direct jet printing on the sized textile semi-finished products. This method is suitable for use with paint, reactive, disperse and acid dye inks. The process is as follows: select the appropriate semi-finished fabric (without softener) according to the type of ink, perform sizing, drying, and winding processes, and then directly print on the digital equipment (the fabric is the same as the paper), and then dry, steam, etc. Chemical, washing, drying, softening and shaping processes.
Cold transfer printing: It is a printing method that first prints textile dyes on specially coated paper, and then transfers the pattern to textiles through a cold transfer printing machine. This method is suitable for all kinds of fabrics except blended fabrics. The ink used is reactive, disperse, acid and other dye inks. This method also requires decals to be embossed on the semi-finished fabric. There are two processing methods for embossed fabrics: one is to carry out cold pile chemical reaction treatment to fix the color (the fabric needs to be chemically treated in advance); the other is to carry out traditional processes such as steaming, washing, and shaping.
Thermal transfer method: firstly print the processed pattern on a specific paper with disperse dye ink, and cover the printed pattern on the fabric to be printed after drying. Enter the thermal transfer machine, heat and press the fabric to sublimate (vaporize) the dye ink on the transfer paper pattern, and transfer it to the fabric through the thermal transfer machine to complete the entire printing without fixing the color. The transfer cloth is processed from semi-finished products without softener, which may affect the coloring rate.
