Heatset Opaque Print Paste is water-based fabric colour most suited for the permanent decoration of cotton-based fabrics.
Heatset Opaque Print Paste colours are transparent and will show best on both light and dark fabric. If application is to be on coloured fabric, the end result will be a blend of the fabric colour and the colour applied.
Colours are intermixable and clean with water.
They are not suitable to be used as a fabric dye in a dye bath.
Heatset Opaque Print Paste is best applied by screenprinting or hand painting.
Use “straight from the pot” for screenprinting. If reduced viscosity is required for hand painting, add Heatset Handpaint Medium to reach desired consistency.
For pastel shades, mix colour with Print Paste.
Heatset Opaque Print Paste requires heat fixing to ensure maximum colourfastness when laundered.
Colour must be dry before heat fixing. Use a hand iron on cotton setting (no steam) and heat for 3 – 5 minutes at 150 degrees C. For large areas it is advised to iron small areas at a time.
RECOMMENDED HEAT FIXING TIMES:
3 minutes at 180oC - for hand iron use cotton setting.
5 minutes at 140oC - for hand iron use wool setting
10 minutes at 120oC
Any form of dry heat will fix Heatset Opaque Print Paste.
Wash test to determine best time/heat cycle.
IMPORTANT Before batch printing - TEST the correct fixing procedure by washing and rubbing the test print.
Do not print onto "dressed" fabrics without first removing all the dressing.
New fabric often contains “dressing” which can cause problems with uneven colour uptake and/or colour loss on washing.
Dressing should be removed by washing thoroughly prior to decorating.
