Crimplene

Crimplene (polyester) is a thick yarn used to make a fabric of the same name. The resulting cloth is heavy, wrinkle-resistant and retains its shape well. Britain's defunct ICI Fibres Laboratory developed the fibre in the early 1950s and named it after the Crimple Valley in which the company was situated. Crimplene was used in garments that required a permanently pressed look, such as skirts and trousers.
