Colorfastness to laundering of reactive dyed 100% cotton poplin fabrics having functional finishes of (1) bleach, scour, desize (BSD); (2) bleach, scour, desize/durable press (BSD/DP); (3) bleach, scour, desize/durable press/fluorochemical (BSD/BP/FL) was studied. The bleached, scoured, desized fabric type accepted the greatest amount of dyestuff initially and continued to exhibit the best colorfastness following successive launderings.
