Qiana is a silky nylon fiber first developed by DuPont in 1968 [1].
Initially intended for high-end fashions, it became a popular material
in the 1970s for faux-silk, men's shirts, displaying bold patterns. The
shirts were generally cut tight and included wide collars to fit over
the collars of the double-knit suit coats which were worn popularly to discos.
