Five materials that were either stretchable, inherently flame retardant, or both were selected for repellent treatment. A Kermel/viscose blend, a flame retardant viscose/pbi blend, a Nomex/Kevlar blend, a Lycra/polycotton blend and a Lycra/cotton blend all exhibited excellent repellent properties (oil, water, phosphate) after treatment. Laundering of treated materials only reduced the oil repellency somewhat and had no effect on the phosphate or water repellencies. The flame retardancy was not degraded by the repellent treatment.
