The artificial fibers research program took place at DuPont's Experimental Research Station in Wilmington, Delaware, where the researchers spent nearly a decade testing materials and spinning processes. Their first experiments in the late 1920s and early 1930s had suggested that polymers might become the building blocks for an entirely new kind of fiber. After experimenting briefly with caprolactam (which they could not get to polymerize at that time) and polyester based fibers (which could not withstand the heat of boiling water and were therefore neither washable nor ironable), they turned their attention to another class of chemicals, polyamides.
