Urea, a humectant, is used where direct application of dyes is required (handpainting and printing reactive dyes), not used in vat or low water immersion dyeing.
What is the purpose of using Urea?
Urea makes it possible to dissolve more dye in a given volume, this leads to darker more vivid colours. It does this by slowing the drying process (Humectant properties) allowing more time for the dye to react.
Combine with Sodium Alginate to thicken screen printing direct dye applications.
How much Urea do I use?
By adding 5-10gm (maximum 10g) of Urea per kilo of Textile Printing Ink slows down the drying process
