Four Methods of Transfer Printing Fabric Technology

  •  

    1. Sublimation method

    This is the most commonly used method for transfer printing fabric. Based on the sublimation characteristics of disperse dyes, disperse dyes with molecular weight of 250~400 and particle diameter of 0.2~2 microns, water-soluble carrier (such as sodium alginate) or alcohol-soluble carrier (such as ethyl cellulose) and oil-soluble resin are used to make ink, which is treated on a transfer printing machine at 200~230°C for 20~30 seconds to transfer the disperse dyes to synthetic fibers such as polyester

    2. Swimming method

    Dyes in the ink layer of transfer paper are selected according to the properties of fibers. First, the fabric was padded with a mixture of fixing AIDS and paste, then the dye was transferred from the transfer printing paper to the fabric and fixed by hot-pressing migration in wet state, and finally, it was wet treated by steaming and washing. When dye is transferred, there needs to be a great pressure between fabric and transfer paper.

    3. Melting method

    The ink layer of transfer paper is based on dye and wax. By melting and pressing, the ink layer is embedded in the fabric, so that part of the ink is transferred to the fiber, and then the corresponding post-treatment is made according to the nature of the dye. When the melting method is adopted, a large pressure is needed, and the dye transfer rate increases with the increase of pressure.

    4. Ink layer stripping method

    Using ink which can produce strong adhesion to fiber after being exposed to heat, the whole ink layer can be transferred from transfer paper to fabric under a small pressure, and then the corresponding fixation treatment is carried out according to the nature of dye.
