The successful development of the thermal transfer printing machine makes the printing process easier and easier to operate. The thermal transfer printing machine is a new printing and dyeing process that has gradually emerged internationally in recent years. Special printing and dyeing with advanced printing technology, printing all the required color patterns on special paper, making transfer printing paper with various fancy, the development of printing technology makes more and more printing equipment in the industry It is widely used.
The thermal transfer printing machine has the unique advantages of fast and environmental protection:
The principle of thermal transfer printing is somewhat similar to the transfer printing method. In thermal transfer printing, first print patterns on paper with disperse dyes and printing inks, and then store the printing paper (also called transfer paper) for use by textile printing plants.
When printing fabrics, the transfer paper and the unprinted surface are stuck together face to face through a thermal transfer printing machine, and pass through the machine at about 210 ° C (400T). At such high temperatures, the dye on the transfer paper sublimates and transfers On the fabric, the printing process is completed without further processing. The process is relatively simple and does not require the expertise required in the production of roller printing or rotary screen printing.
Disperse dyes are the only dyes that can sublimate, in a sense, the only dyes that can be used for thermal transfer printing, so this process can only be used on fabrics composed of fibers that have affinity for such dyes, including acetate fibers and acrylic Nitrile fiber, polyamide fiber (nylon) and polyester fiber. When thermal transfer printing, fabric printing factories have to buy this printing paper from highly specialized printing paper manufacturers. The transfer paper can be printed according to the requirements of the pattern designer and customers (ready-made patterns can also be used for transfer paper printing).
The thermal transfer printing can be used to print clothing pieces (such as edge printing, chest pocket embroidery, etc.). In this case, a specially designed pattern is used. Thermal transfer printing stands out from the printing process as a complete fabric printing method, therefore, the use of a large and expensive dryer, steamer, washing machine and stenter is omitted. Because the printed paper can be inspected before printing, this eliminates inaccurate registration and other defects. Therefore, thermal transfer printing fabrics rarely appear defective.
