manufactured fiber means: A fiber which can be produced from an industrial process but isn’t found in nature. These fibers can be made using natural materials which are not suitable for use in textiles. Rayon and lyocell are examples. They can be made of wood chips, cotton linters or rayon. Linters are short fibers that cannot be spun into yarn. Chemicals are used to make synthetic fibers such as nylon or polyester. (in Fashion Dictionary)
