Polyester oxford fabric can be dyed using various dyeing methods such as disperse dyeing, vat dyeing, and reactive dyeing. Here are the general steps involved in the dyeing process of polyester oxford fabric using disperse dyeing method:
Preparation of fabric: The fabric is washed and cleaned to remove any dirt, oil, or other impurities that may interfere with the dyeing process.
Preparation of dye: Disperse dye is dissolved in hot water and then added to a dye bath along with other necessary chemicals such as dispersing agents, leveling agents, and anti-foaming agents.
Dyeing: The fabric is then immersed in the dye bath and heated to a specific temperature and time, which allows the dye to penetrate the polyester fibers. The temperature and time depend on the type of dye used and the desired color intensity.
Rinsing: After dyeing, the fabric is rinsed thoroughly with water to remove any excess dye or chemicals.
Fixation: The dyed fabric is then subjected to a process called fixation, which involves exposing the fabric to high temperature and pressure. This helps to fix the dye onto the fabric fibers, ensuring that the color does not fade or wash out easily.
Finishing: Finally, the fabric is dried, and any necessary finishing treatments such as softening or water-repellent treatment are applied.
