In transfer printing, the dye is printed on the transfer printing paper first, and then the dye in the pattern is transferred to the textile through processing during the transfer printing, and fixed to form the pattern. According to different transfer methods, transfer printing can be divided into thermal transfer printing and cold transfer printing. Thermal transfer printing refers to the printing process in which the printed paper with disperse dye patterns is transferred to the fabric under a certain temperature and pressure. It is especially suitable for polyester fabrics. Cold transfer printing refers to a printing process in which the printed paper with reactive dye patterns is transferred to the cotton cloth that has been dipped in lye under a certain pressure, and then the printing process is cold piled to fix the color.
Because the cold transfer printing technology can directly use the transfer printing paper at room temperature, the popular elements can be transferred to the denim fabric by the high-precision cold transfer printing machine, and the effect of bright colors, clear layers and exquisite patterns can be obtained. At the same time, cold transfer printing has attracted the attention of consumers and industry professionals due to the use of cold-batch fixation in the fixing process, which has a shorter process flow and is more energy-saving and environmentally friendly.
