Refers to a specific manufactured fiber, which is a modification, a variant, of an existing generic fiber and which has been registered with the government as a particular brand and whose distribution and use is controlled by the manufacturer. For example, Spandex can be used by any company which makes the fiber but Lycra (a confined formula of Lycra) can only be used by the company which created and registered it. Other generic fibers: Acetate, Acrylic, Nylon, Olefin, Polyester, Dacron, Rayon, Spandex, Aramid, Lyocell, Sulfar PBI. Because of the larger amount of money dedicated to educating the consumer about these branded fibers, they develop an appeal which is helpful to retail selling. Cooperative advertising dollars can support both the fiber and the retailer purchasing the fiber within the garments advertised.
