The Principle and Characteristics of Textile Sublimation Transfer Technology

Sublimation transfer technology has developed rapidly in China and has a wide range of applications. In addition, due to its low investment in equipment, outstanding printing effect, no pollution, resource saving and other reasons, the application prospect has huge development space.

Process principle and characteristics

Dye sublimation transfer printing firstly uses a printing method to print special printing dyes on transfer paper, and then heat and pressurize to transfer the dyes to fabrics. Specifically, it is based on the sublimation characteristics of disperse dyes, selects disperse dyes with a sublimation temperature range of 180~240℃, mixes them with slurry to make color ink, and uses Ep~J, The color ink is printed on the transfer paper by the method of printing the color ink on the transfer paper, and the transfer paper printed with the pattern and the pattern is in close contact with the fabric, and is processed on a transfer printing machine at 200~230 ° C for 10~30s, and the dye is transferred from the printing paper to the fabric. After diffusion, it enters the interior of the fabric to achieve the purpose of coloring.

In the process of heating sublimation, in order to enable the dye to diffuse in a directional manner, a vacuum is often drawn on the lower side of the bottom pole of the dyed object, so that the dye can achieve directional diffusion and transfer and improve the transfer quality.

At present, the technology that is really used in commercial and industrial digital printing on a large scale is mainly dye-sublimation transfer printing technology.

With the introduction of dye-sublimation inks with price advantages in China (the dye-sublimation transfer inks are mainly imported from South Korea and Italy are expensive), and the digitization of printing technology, the application fields of dye-sublimation transfer technology have become more extensive. To sum up, the thermal sublimation transfer technology has the following four characteristics:

Features of dye sublimation transfer technology

1. The printing effect is good.

The fabrics printed by sublimation transfer technology have fine patterns, bright colors, rich and clear layers, high artistry and strong three-dimensional sense, which are difficult to achieve by general printing methods, and can print patterns in photography and painting styles.

1. The printed product is soft to the touch and has a long service life.

The biggest feature of sublimation transfer printing is that the dye can diffuse into polyester or fiber, the printed product feels very soft and comfortable, and the existence of the ink layer is basically not felt. In addition, because the ink has been dried during the transfer process, the life of the image is as long as the life of the garment itself, and there will be no wear and tear on the printed graphics and text, which affects the beauty of the fabric.

1. The process is simple, the equipment investment is small, the flexibility is strong, and the genuine product rate is high.

Sublimation transfer printing can be done at one time with Ep~, J multi-color patterns without matching flowers. According to the individual needs of customers, the job can be printed in a short period to meet the individual needs of customers.

1. Save resources and protect the environment.

Different from traditional fabric printing, sublimation transfer printing does not require post-processing such as steaming and washing, saving a lot of water resources and no sewage discharge, which can save resources and protect the environment.
