Discharge Screenprinting?
  • I'm looking for anyone with experience in using Jacquard Discharge Paste with screenprinting?

    When drying the garment, can it go through a gas conveyer belt dryer or does it absolutely have to be steamed? If steaming is necessary, can you just spray the garment with a light coat of water while it runs down the dryer? What would I set the dryer temp too?

    Also, water-based emulsion on the screen would be a necessity with this product, correct?

    I haven't used this yet, but a client of mine wants to do this and I'm not 100% sure if I can. Thanks for any help in advance and any other helpful tips would be appreciated.
  • Hi,

    The discharge paste must be steamed and I don't think that spraying with water in the dryer will work unfortunately. Here are our instructions for stove top steaming or you can use a steam iron for small projects.

    There are commercial steamers available or smaller pieces can be steamed at home with the following method. You will need a large pot with a rack that fits inside, white newsprint, masking tape, and aluminum foil.

    Roll the fabric in newsprint, making sure there is a layer of paper between each roll of fabric. The paper should extend a few inches beyond the fabric on either end of the roll.
    When all the fabric has been rolled, wrap newsprint around the bundle a few extra times. Secure the roll by taping length of roll. Coil gently to a size that will fit into the pot. Tape securely.
    Place rack into the pot. Pour water to a level that is well below the bottom of the rack. Make sure top of rack is dry and place bundle on the rack.
    Shape a piece of aluminum foil into a dome and place it over the bundle for protection. This will keep condensation from dripping on the silk. Make sure neither the packet nor the foil touches the sides of the pot.
    Cover the pot with the lid. Place the pot on the stove and bring water to a boil. Reduce the heat but keep it high enough to produce steam. Steam the packet for 1 hour. Allow packet to cool. Unwrap the silk and rinse in cool water to remove excess dye. Lay flat to dry and you're done.


    The emulsion MUST BE WATER RESISTANT!!!!
