Transfer Printing Shawls with Modal and Silk

What is heat transfer printing:
Heat transfer printing technology was developed by European printing technologists in the late 1960s. This process uses the sublimation principle of disperse dyes or inks, takes paper as the carrier, and transfers the patterns printed on paper to fabric through temperature sublimation.
Heat transfer printing technology began to be put into production in some printing factories in the early 1970s, but most of this stage is to transfer the pattern of transfer printing paper to chemical fiber fabrics such as clothing pieces, ready-made clothes, bags or cutting pieces. In the mid-1970s, transfer printing technology began to be put into continuous production like traditional printing. Due to the improvement of printing equipment, the quality of transfer printing base paper was correspondingly improved. Its machine printing paper production energy was generally 2000~3000m/h.

Classification of heat transfer printing:
Heat transfer printing is usually divided into hot-melt transfer printing and heat sublimation transfer printing. Hot-melt transfer printing is commonly used in all cotton products, with the disadvantage of poor hand feel and air permeability. Thermal sublimation transfer printing is often used in polyester transfer printing, but its disadvantage is that the plate making cost is high.
Sublimation is the most commonly used method in heat transfer printing. The principle is to transfer the disperse dyes to synthetic fibers such as polyester and fix them at high temperature by using the sublimation characteristics of disperse dyes.

The specific process is to pass the pattern through the roller or flat screen after plate making, or the circular screen printing machine can print it on the paper with disperse dye or ink. Then, the transfer printing paper printed with patterns will be combined with the fabric through the transfer printing machine under the applicable temperature and pressure conditions. Through the physical and chemical action, the pattern on the paper will be sublimated and transferred to the fabric surface instantly, and at the same time, it will diffuse and penetrate into the fiber inner layer to be fixed. This is the current process of heat transfer printing of polyester fabric. Heat sublimation transfer printing can be divided into offset printing, gravure printing, silk screen printing and data printing according to different printing methods.
