Sublimation transfer features:
1. Anhydrous production, zero discharge of wastewater, meet the requirements of human protection and living environment;
2. The pattern is fine and the scenery is vivid, surpassing any traditional printing process level, especially using lithographic printing transfer printing paper, the printing effect can reach the paper color printing effect;
3. The process is simple and fast without post-processing. Sublimation transfer printing on cotton fabrics is currently the easiest way to polymerize polymer films on the surface of fabrics. The authors have conducted material selection and application tests for this method for many years. There is a ZY-TG cotton cloth sublimation transfer printing treatment agent. The application works well and is briefly described as follows:
One. Features 1. The pattern transferred on the fabric is bright, full and clear.
2. Friction, soaping, washing color fastness can reach 3 to 4 levels.
3. Feel soft.
Two. Coating method 1. The padding machine dries the fabric after two dipping and two rolling.
2. The fabric transfer surface is sprayed and dried.
3. Drying after screen printing on the fabric transfer surface.
4. The fabric was immersed in a dilute treatment agent for 10 minutes, and the excess treatment agent was removed and dried.
III. <br> <br> transfer using batch lithographic, drum continuous sublimation heat transfer printing machine for transfer printing. The temperature is 190~210°C, the pressure is 150 g/cm2, and the time is shortened or extended with the temperature.
The method of applying polymer film on the surface of fabrics is used for sublimation and transfer printing on cotton cloth and small textiles. Compared with traditional printing, it is not only environmentally friendly, it has less equipment investment, the technique is simple, the operation is convenient, the pattern is fine, and it is suitable for small batches, varieties, and speeds. Fast market demand, but also can get very good economic benefits.
