Description

technical field [0001] The invention relates to the field of vacuum heat transfer printing materials, in particular to a glass fiber reinforced PP / PA6 composite material and its preparation method and application. Background technique [0002] Thermal transfer printing is an emerging printing process. The principle of thermal transfer printing is to pre-print the pattern on the surface of the film, and then heat it to sublimate the pigment and diffuse it to the printed object. The printed pattern is rich in layers and bright in color. Ever-changing, small color difference, good reproducibility, can achieve the effect required by the designer, and is suitable for mass production. [0003] Vacuum thermal transfer printing is a kind of thermal transfer printing. It is mainly used to print irregular objects. Generally, vacuum thermal transfer printing needs to be vacuumed during the processing process, and the temperature is controlled at 150°C for about half an hour. Due to th...
