Polyester fabrics and filament were treated by heat transfer printing. The temperature rise of the fabrics during the treatment and the changes of mechanical properties of the fabrics and the fine structure of the filament due to the treatment were investigated.
The heat transfer printing was more effective for the temperature rise than the conventional heat treatment in hot air. In the case of the heat transfer printing, the time taken to reach a fixed temperature was about 20-30 sec. The thickness and the compressibility of the fabrics treated by the heat transfer printing decreased remarkably with the rise of the treating temperature. Also the stiffness increased by the treatment. The crystallinity and the crystallite size of the filament by the treatment were larger than those by the conventional heat setting.
