Thermal transfer printing is referred to as thermal transfer printing. The principle of transfer printing fabric is somewhat similar to the transfer printing method. In thermal transfer printing, first use disperse dyes and printing inks to print patterns on paper, and then store the printing paper (also called transfer paper) for use in textile printing plants.
When fabric printing, through a thermal transfer printing machine, the transfer paper and the unprinted surface are stuck together, and the machine passes through the machine at about 210℃ (400T). Under such high temperature, the dye on the transfer paper is sublimated and transferred On the fabric, the printing process is completed without further processing. The process is relatively simple and does not require professional knowledge required in the production of roller printing or rotary screen printing.
Disperse dyes are the only dyes that can be sublimated. In a sense, they are the only dyes that can be used for thermal transfer printing. Therefore, this process can only be used on fabrics composed of fibers that have an affinity for this type of dye, including acetate fibers and acrylic. Nitrile fiber, polyamide fiber (nylon), and polyester fiber.
In heat transfer printing, the fabric printing plant purchases this printing paper from a highly specialized printing paper manufacturer. Transfer paper can be printed according to the requirements of pattern designers and customers (ready-made patterns can also be used for transfer paper printing). Thermal transfer printing can be used to print garment pieces (such as edge printing, breast pocket embroidery, etc.). In this case, a specially designed pattern should be used.
Thermal transfer printing, as a complete fabric printing method, stands out from the printing process. Therefore, it eliminates the need for large and expensive dryers, steaming machines, washing machines, and centers.
Since the printed paper can be inspected before printing, inaccuracy of the pattern and other defects are eliminated. Therefore, the thermal transfer printed fabric rarely appears defective.
Advantages and applications of transfer printing fabric:
Transfer printing has the characteristics of lightfastness, washing resistance, strong colorfastness, and rich colors. It can be used for printing on clothing, home textiles (curtains, sofas, tablecloths, umbrellas, shower curtains, luggage) and other products.
