Description

Discharge screen printing ink  formula is a type of ink used in textile printing that removes (discharges) the dye from the fabric, leaving the original fabric color or allowing for the addition of new color in the discharged area. This ink is particularly useful for printing on dark fabrics because it allows for bright, vibrant designs without the need for a heavy layer of ink, which can make the fabric feel stiff.

Process of Using Discharge Screen Printing Ink

  1. Preparation:
    • Fabric Selection: Choose the appropriate fabric for discharge printing. Natural fibers like cotton work best.
    • Screen Preparation: Create a stencil on the screen for the desired design. A mesh count suitable for the level of detail in the design should be chosen.
  2. Mixing the Ink:
    • Formulation: Mix the discharge ink components according to the desired formulation. Ensure the discharge agent and activator are properly combined with the binder and other additives.
    • Pigment Addition: If a colored discharge is desired, mix the appropriate pigments into the discharge ink.
  3. Printing:
    • Application: Load the ink onto the screen and use a squeegee to press the ink through the mesh onto the fabric.
    • Multiple Passes: Depending on the fabric and design, multiple passes may be necessary to ensure even application.
  4. Curing:
    • Heat Activation: Cure the printed fabric at a specific temperature (typically around 160°C or 320°F) to activate the discharge agent. This process usually takes 2-3 minutes.
    • Steaming (if needed): Some formulations might require steaming at around 96°C (205°F) for a fixed time using saturated steam.
  5. Post-Processing:
    • Washing: After curing, wash the fabric to remove any residual chemicals and unreacted discharge agent.
    • Drying: Dry the fabric at room temperature or using a dryer.

Properties of Discharge Screen Printing Ink

  • Color Brightness: Produces bright and vibrant colors, especially on dark fabrics.
  • Soft Hand Feel: Maintains the natural feel of the fabric since the ink removes the dye rather than adding a thick layer.
  • Detail: Capable of producing detailed and intricate designs.
  • Compatibility: Works best on natural fibers like cotton.

Applications

  • Apparel: T-shirts, hoodies, and other garments requiring vibrant prints.
  • Home Textiles: Bedding, curtains, and other home decor items.
  • Promotional Items: Bags, hats, and other promotional materials.
