What is Urea or Organic nitrogen?
Urea or Organic nitrogen is called a wetting agent. It keeps the textiles damp for a longer period of time. The longer the fabric is damp and active with the dyes, the stronger the color will be. In dry or arid conditions, Organic nitrogen is a good thing to add to your dye baths. For thinner fibers, especially silks, this chemical is essential to keep things moist for as long as is necessary to get the colors we need.
