Heat transfer printing is a new printing and dyeing process that has gradually emerged in the world in recent years. The development of printing technology has made more and more printing equipment widely used in the industry. The sublimation calender machine is a professional equipment designed for the thermal transfer printing process.
The printing principle of the heatl transfer printing machine is somewhat similar to the transfer printing method. In thermal transfer printing, a pattern is first printed on paper with a dispersion-containing dye and a printing ink, and then the printing paper (also referred to as a transfer paper) is stored for use in a textile printing factory. When the fabric is printed, the transfer paper and the unprinted face-to-face are pasted together by a thermal transfer printing machine, and the dye on the transfer paper is sublimated and transferred at such a high temperature at a temperature of about 210 ° C (400 t). On the fabric, the printing process is completed without further processing. The process is relatively simple and does not require the necessary expertise in the production of roller printing or rotary screen printing.
Disperse dyes are the only dyes that can be sublimed. In a sense, they are the only dyes that can be printed on thermal transfer printing machines. Therefore, the process can only be applied to fabrics composed of fibers having affinity for such dyes, including acetate fibers. , acrylonitrile rayon fiber, polyamide fiber (nylon) and polyester fiber. When printing on thermal transfer printing machines, fabric printing plants purchase such printing paper from highly specialized printing paper manufacturers. Transfer paper can be printed according to the requirements of the pattern designer and the customer (off-the-shelf patterns can also be used for transfer paper printing).
Heat transfer printing can be used to print pieces (such as border prints, chest embroidery, etc.), in which case a specially designed pattern is used. Thermal transfer printing machine printing as a complete fabric printing method stands out from the printing process. Thus eliminating the inaccuracy and other symptoms. Therefore, thermal transfer printing fabrics rarely appear defective.
